  • nginx php-fpm empty site

    - by Katafalkas
    I am writing this as I was stuck trying to fix it whole night. We have recently migrated to a new server. Before migration we have been running our site on nginx + cgi (script). After migration we decided to try apache + mod_php. It was rather terrible, and I would like to migrate back to nginx, but this time I want it with php-fpm (as people say its a cool) So I did follow a number of guides and I think i done everything correctly. As well as that I have our old config files for "server" section, which i reviewed and places into new config. So I ended up having an empty site when I enter our URL. (By empty I mean blank page, no letter, errors or anything at all.) In the access log there are some weird errors like: 123.242.148.54 - - [22/Mar/2012:06:08:11 +0200] "-" 400 0 "-" "-" My guess is that php-fpm is not working, but not sure how to confirm it. Maybe some1 could give some help ? Would much appreciate. my nginx config: user nginx; worker_processes 12; error_log /var/log/nginx/error.log; #error_log /var/log/nginx/error.log notice; #error_log /var/log/nginx/error.log info; pid /var/run/nginx.pid; events { worker_connections 4096; } http { include /etc/nginx/mime.types; #default_type application/octet-stream; log_format main '$remote_addr - $remote_user [$time_local] "$request" ' '$status $body_bytes_sent "$http_referer" ' '"$http_user_agent" "$http_x_forwarded_for"'; access_log /var/log/nginx/access.log main; sendfile on; #tcp_nopush on; #keepalive_timeout 0; keepalive_timeout 65; tcp_nodelay on; gzip on; gzip_disable "MSIE [1-6]\.(?!.*SV1)"; fastcgi_buffer_size 256k; fastcgi_buffers 4 256k; server { listen 80; server_name www.example.com; access_log /var/log/nginx/example.access.log; error_log /var/log/nginx/error.log; root /home/www/example; index index.php; client_max_body_size 50M; #error_page 404 /404.html; # phpMyAdmin location /phpmyadmin { root /usr/share/; error_log /var/log/nginx/phpmyadmin.log; try_files $uri $uri/ /index.php; } location ~ ^/phpmyadmin/.*\.php$ { root /usr/share/; error_log /var/log/nginx/phpmyadmin.log; include /etc/nginx/fastcgi_params; fastcgi_pass 127.0.0.1:9000; } # Munin location /monitoring { root /var/www/; auth_basic "Restricted"; auth_basic_user_file /etc/nginx/conf.d/monitoring_users; error_log /var/log/nginx/monitoring.log; index index.html; } # The site location / { try_files $uri $uri/ /index.php/?$uri&$args; } # PHP interpreter location ~ \.php { include /etc/nginx/fastcgi_params; fastcgi_pass 127.0.0.1:9000; } }

  • Broken cups installation on a ubuntu server 64

    - by user67046
    Hi, I am having trouble with an cups installation. It seems to be in a broken state. When i try to reinstall it it stalls, the same if i try to remove it completely. I am running the server version 64 bit of Ubuntu 10.10 with kernel Linux version 2.6.35-22-server. When i try to start the cups daemon with the following command sudo service cups start It just stays there and nothing happens. I have tried to remove it, to be able to reinstall it, with the following command sudo apt-get purge cups It finally stalls with the following message Removing cups ... After that nothing happens. The process tree for the apt-get command looks like this. 1404 1404 1404 ? 00:00:00 sshd 26495 26495 26495 ? 00:00:00 sshd 26581 26495 26495 ? 00:00:00 sshd 26582 26582 26582 pts/4 00:00:00 bash 27158 27158 26582 pts/4 00:00:00 apt-get 27172 27172 27172 pts/2 00:00:00 dpkg 27176 27172 27172 pts/2 00:00:00 cups.prerm 27178 27172 27172 pts/2 00:00:00 stop I have tried to leave the process running for a while to see if i get any error messages but without success.

  • Intelligent "Subtraction" of one text logfile from another

    - by Vi
    Example: Application generates large text log file A with many different messages. It generates similarly large log file B when does not function correctly. I want to see what messages in file B are essentially new, i.e. to filter-out everything from A. Trivial prototype is: Sort | uniq both files Join files sort | uniq -c grep -v "^2" This produces symmetric difference and inconvenient. How to do it better? (including non-symmetric difference and preserving of messages order in B) Program should first analyse A and learn which messages are common, then analyse B showing with messages needs attention. Ideally it should automatically disregard things like timestamps, line numbers or other volatile things. Example. A: 0:00:00.234 Received buffer 0x324234 0:00:00.237 Processeed buffer 0x324234 0:00:00.238 Send buffer 0x324255 0:00:03.334 Received buffer 0x324255 0:00:03.337 Processeed buffer 0x324255 0:00:03.339 Send buffer 0x324255 0:00:05.171 Received buffer 0x32421A 0:00:05.173 Processeed buffer 0x32421A 0:00:05.178 Send buffer 0x32421A B: 0:00:00.134 Received buffer 0x324111 0:00:00.137 Processeed buffer 0x324111 0:00:00.138 Send buffer 0x324111 0:00:03.334 Received buffer 0x324222 0:00:03.337 Processeed buffer 0x324222 0:00:03.338 Error processing buffer 0x324222 0:00:03.339 Send buffer 0x3242222 0:00:05.271 Received buffer 0x3242FA 0:00:05.273 Processeed buffer 0x3242FA 0:00:05.278 Send buffer 0x3242FA 0:00:07.280 Send buffer 0x3242FA failed Result: 0:00:03.338 Error processing buffer 0x324222 0:00:07.280 Send buffer 0x3242FA failed One of ways of solving it can be something like that: Split each line to logical units: 0:00:00.134 Received buffer 0x324111,0:00:00.134,Received,buffer,0x324111,324111,Received buffer, \d:\d\d:\d\d\.\d\d\d, \d+:\d+:\d+.\d+, 0x[0-9A-F]{6}, ... It should find individual words, simple patterns in numbers, common layouts (e.g. "some date than text than number than text than end_of_line"), also handle combinations of above. As it is not easy task, user assistance (adding regexes with explicit "disregard that","make the main factor","don't split to parts","consider as date/number","take care of order/quantity of such messages" rules) should be supported (but not required) for it. Find recurring units and "categorize" lines, filter out too volatile things like timestamps, addresses or line numbers. Analyse the second file, find things that has new logical units (one-time or recurring), or anything that will "amaze" the system which has got used to the first file. Example of doing some bit of this manually: $ cat A | head -n 1 0:00:00.234 Received buffer 0x324234 $ cat A | egrep -v "Received buffer" | head -n 1 0:00:00.237 Processeed buffer 0x324234 $ cat A | egrep -v "Received buffer|Processeed buffer" | head -n 1 0:00:00.238 Send buffer 0x324255 $ cat A | egrep -v "Received buffer|Processeed buffer|Send buffer" | head -n 1 $ cat B | egrep -v "Received buffer|Processeed buffer|Send buffer" 0:00:03.338 Error processing buffer 0x324222 0:00:07.280 Send buffer 0x3242FA failed This is a boring thing (there are a lot of message types); also I can accidentally include some too broad pattern. Also it can't handle complicated things like interrelation between messages. I know that it is AI-related. May be there are already developed tools?

  • http.conf setup to simplify using 'localhost:81'

    - by Will
    I'm installing portable wampserver within my dropbox folder so I can access anywhere.

  • Is the Cloud ready for an Enterprise Java web application? Seeking a JEE hosting advice.

    - by Jakub Holý
    Greetings to all the smart people around here! I'd like to ask whether it is feasible or a good idea at all to deploy a Java enterprise web application to a Cloud such as Amazon EC2. More exactly, I'm looking for infrastructure options for an application that shall handle few hundred users with long but neither CPU nor memory intensive sessions. I'm considering dedicated servers, virtual private servers (VPSs) and EC2. I've noticed that there is a project called JBoss Cloud so people are working on enabling such a deployment, on the other hand it doesn't seem to be mature yet and I'm not sure that the cloud is ready for this kind of applications, which differs from the typical cloud-based applications like Twitter. Would you recommend to deploy it to the cloud? What are the pros and cons? The application is a Java EE 5 web application whose main function is to enable users to compose their own customized Product by combining the available Parts. It uses stateless and stateful session beans and JPA for persistence of entities to a RDBMS and fetches information about Parts from the company's inventory system via a web service. Aside of external users it's used also by few internal ones, who are authenticated against the company's LDAP. The application should handle around 300-400 concurrent users building their product and should be reasonably scalable and available though these qualities are only of a medium importance at this stage. I've proposed an architecture consisting of a firewall (FW) and load balancer supporting sticky sessions and https (in the Cloud this would be replaced with EC2's Elastic Load Balancing service and FW on the app. servers, in a physical architecture the load-balancer would be a HW), then two physical clustered application servers combined with web servers (so that if one fails, a user doesn't loose his/her long built product) and finally a database server. The DB server would need a slave backup instance that can replace the master instance if it fails. This should provide reasonable availability and fault tolerance and provide good scalability as long as a single RDBMS can keep with the load, which should be OK for quite a while because most of the operations are done in the memory using a stateful bean and only occasionally stored or retrieved from the DB and the amount of data is low too. A problematic part could be the dependency on the remote inventory system webservice but with good caching of its outputs in the application it should be OK too. Unfortunately I've only vague idea of the system resources (memory size, number and speed of CPUs/cores) that such an "average Java EE application" for few hundred users needs. My rough and mostly unfounded estimate based on actual Amazon offerings is that 1.7GB and a single, 2-core "modern CPU" with speed around 2.5GHz (the High-CPU Medium Instance) should be sufficient for any of the two application servers (since we can handle higher load by provisioning more of them). Alternatively I would consider using the Large instance (64b, 7.5GB RAM, 2 cores at 1GHz) So my question is whether such a deployment to the cloud is technically and financially feasible or whether dedicated/VPS servers would be a better option and whether there are some real-world experiences with something similar. Thank you very much! /Jakub Holy PS: I've found the JBoss EAP in a Cloud Case Study that shows that it is possible to deploy a real-world Java EE application to the EC2 cloud but unfortunately there're no details regarding topology, instance types, or anything :-(

  • How to serve static files for multiple Django projects via nginx to same domain

    - by thanley
    I am trying to setup my nginx conf so that I can serve the relevant files for my multiple Django projects. Ultimately I want each app to be available at www.example.com/app1, www.example.com/app2 etc. They all serve static files from a 'static-files' directory located in their respective project root. The project structure: Home Ubuntu Web www.example.com ref logs app app1 app1 static bower_components templatetags app1_project templates static-files app2 app2 static templates templatetags app2_project static-files app3 tests templates static-files static app3_project app3 venv When I use the conf below, there are no problems for serving the static-files for the app that I designate in the /static/ location. I can also access the different apps found at their locations. However, I cannot figure out how to serve all of the static files for all the apps at the same time. I have looked into using the 'try_files' command for the static location, but cannot figure out how to see if it is working or not. Nginx Conf - Only serving static files for one app: server { listen 80; server_name example.com; server_name www.example.com; access_log /home/ubuntu/web/www.example.com/logs/access.log; error_log /home/ubuntu/web/www.example.com/logs/error.log; root /home/ubuntu/web/www.example.com/; location /static/ { alias /home/ubuntu/web/www.example.com/app/app1/static-files/; } location /media/ { alias /home/ubuntu/web/www.example.com/media/; } location /app1/ { include uwsgi_params; uwsgi_param SCRIPT_NAME /app1; uwsgi_modifier1 30; uwsgi_pass unix:///home/ubuntu/web/www.example.com/app1.sock; } location /app2/ { include uwsgi_params; uwsgi_param SCRIPT_NAME /app2; uwsgi_modifier1 30; uwsgi_pass unix:///home/ubuntu/web/www.example.com/app2.sock; } location /app3/ { include uwsgi_params; uwsgi_param SCRIPT_NAME /app3; uwsgi_modifier1 30; uwsgi_pass unix:///home/ubuntu/web/www.example.com/app3.sock; } # what to serve if upstream is not available or crashes error_page 400 /static/400.html; error_page 403 /static/403.html; error_page 404 /static/404.html; error_page 500 502 503 504 /static/500.html; # Compression gzip on; gzip_http_version 1.0; gzip_comp_level 5; gzip_proxied any; gzip_min_length 1100; gzip_buffers 16 8k; gzip_types text/plain text/css application/x-javascript text/xml application/xml application/xml+rss text/javascript; # Some version of IE 6 don't handle compression well on some mime-types, # so just disable for them gzip_disable "MSIE [1-6].(?!.*SV1)"; # Set a vary header so downstream proxies don't send cached gzipped # content to IE6 gzip_vary on; } Essentially I want to have something like (I know this won't work) location /static/ { alias /home/ubuntu/web/www.example.com/app/app1/static-files/; alias /home/ubuntu/web/www.example.com/app/app2/static-files/; alias /home/ubuntu/web/www.example.com/app/app3/static-files/; } or (where it can serve the static files based on the uri) location /static/ { try_files $uri $uri/ =404; } So basically, if I use try_files like above, is the problem in my project directory structure? Or am I totally off base on this and I need to put each app in a subdomain instead of going this route? Thanks for any suggestions TLDR: I want to go to: www.example.com/APP_NAME_HERE And have nginx serve the static location: /home/ubuntu/web/www.example.com/app/APP_NAME_HERE/static-files/;

  • Debian Lenny to Debian Squeeze upgrade problems

    - by Roland Soós
    Hi! Yesterday I made a dist-upgrade on my Debian Lenny server. I thought it will be easy as an usual upgrade, but it's not. I got a lot of problem after the update: # apt-get upgrade Reading package lists... Done Building dependency tree Reading state information...

  • nginx 502 Bad Gateway on every external site

    - by Leandros
    I just installed nginx and followed the guides on the official site, to set it up with php5-fpm, but it just won't work. Not even the default site, without php is working outside of my server. Tried listen = 127.0.0.1:7777 and listen = /var/run/php5-fpm.sock Both don't work. I can access http://localhost with lynx on my server, but not from somewhere else (with external ip obviously).

  • Windows 7: How to place SuperFetch cache on an SSD?

    - by Ian Boyd
    I'm thinking of adding a solid state drive (SSD) to my existing Windows 7 installation. I know I can (and should) move my paging file to the SSD: Should the pagefile be placed on SSDs? Yes. Most pagefile operations are small random reads or larger sequential writes, both of which are types of operations that SSDs handle well. In looking at telemetry data from thousands of traces and focusing on pagefile reads and writes, we find that Pagefile.sys reads outnumber pagefile.sys writes by about 40 to 1, Pagefile.sys read sizes are typically quite small, with 67% less than or equal to 4 KB, and 88% less than 16 KB. Pagefile.sys writes are relatively large, with 62% greater than or equal to 128 KB and 45% being exactly 1 MB in size. In fact, given typical pagefile reference patterns and the favorable performance characteristics SSDs have on those patterns, there are few files better than the pagefile to place on an SSD. What I don't know is if I even can put a SuperFetch cache (i.e. ReadyBoost cache) on the solid state drive. I want to get the benefit of Windows being able to cache gigabytes of frequently accessed data on a relativly small (e.g. 30GB) solid state drive. This is exactly what SuperFetch+ReadyBoost (or SuperFetch+ReadyDrive) was designed for. Will Windows offer (or let) me place a ReadyBoost cache on a solid state flash drive connected via SATA? A problem with the ReadyBoost cache over the ReadyDrive cache is that the ReadyBoost cache does not survive between reboots. The cache is encrypted with a per-session key, making its existing contents unusable during boot and SuperFetch pre-fetching during login. Update One I know that Windows Vista limited you to only one ReadyBoost.sfcache file (I do not know if Windows 7 removed that limitation): Q: Can use use multiple devices for EMDs? A: Nope. We've limited Vista to one ReadyBoost per machine Q: Why just one device? A: Time and quality. Since this is the first revision of the feature, we decided to focus on making the single device exceptional, without the difficulties of managing multiple caches. We like the idea, though, and it's under consideration for future versions. I also know that the 4GB limit on the cache file was a limitation of the FAT filesystem used on most USB sticks - an SSD drive would be formatted with NTFS: Q: What's the largest amount of flash that I can use for ReadyBoost? A: You can use up to 4GB of flash for ReadyBoost (which turns out to be 8GB of cache w/ the compression) Q: Why can't I use more than 4GB of flash? A: The FAT32 filesystem limits our ReadyBoost.sfcache file to 4GB Can a ReadyBoost cache on an NTFS volume be larger than 4GB? Update Two The ReadyBoost cache is encrypted with a per-boot session key. This means that the cache has to be re-built after each boot, and cannot be used to help speed boot times, or latency from login to usable. Windows ReadyDrive technology takes advantage of non-volatile (NV) memory (i.e. flash) that is incorporated with some hybrid hard drives. This flash cache can be used to help Windows boot, or resume from hibernate faster. Will Windows 7 use an internal SSD drive as a ReadyBoost/*ReadyDrive*/SuperFetch cache? Is it possible to make Windows store a SuperFetch cache (i.e. ReadyBoost) on a non-removable SSD? Is it possible to not encrypt the ReadyBoost cache, and if so will Windows 7 use the cache at boot time? See also SuperUser.com: ReadyBoost + SSD = ? Windows 7 - ReadyBoost & SSD drives?

  • Nginx + PHP - No input file specified for 1 server block. Other server block works fine

    - by F21
    I am running Ubuntu Desktop 12.04 with nginx 1.2.6. PHP is PHP-FPM 5.4.9. This is the relevant part of my nginx.conf: http { include mime.types; default_type application/octet-stream; sendfile on; keepalive_timeout 65; server { server_name testapp.com; root /www/app/www/; index index.php index.html index.htm; location ~ \.php$ { fastcgi_intercept_errors on; fastcgi_pass 127.0.0.1:9000; fastcgi_index index.php; fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name; include fastcgi_params; } } server { listen 80 default_server; root /www index index.html index.php; location ~ \.php$ { fastcgi_intercept_errors on; fastcgi_pass 127.0.0.1:9000; fastcgi_index index.php; fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name; include fastcgi_params; } } } Relevant bits from php-fpm.conf: ; Chroot to this directory at the start. This value must be defined as an ; absolute path. When this value is not set, chroot is not used. ; Note: you can prefix with '$prefix' to chroot to the pool prefix or one ; of its subdirectories. If the pool prefix is not set, the global prefix ; will be used instead. ; Note: chrooting is a great security feature and should be used whenever ; possible. However, all PHP paths will be relative to the chroot ; (error_log, sessions.save_path, ...). ; Default Value: not set ;chroot = ; Chdir to this directory at the start. ; Note: relative path can be used. ; Default Value: current directory or / when chroot chdir = /www In my hosts file, I redirect 2 domains: testapp.com and test.com to 127.0.0.1. My web files are all stored in /www. From the above settings, if I visit test.com/phpinfo.php and test.com/app/www, everything works as expected and I get output from PHP. However, if I visit testapp.com, I get the dreaded No input file specified. error. So, at this point, I pull out the log files and have a look: 2012/12/19 16:00:53 [error] 12183#0: *17 FastCGI sent in stderr: "Unable to open primary script: /www/app/www/index.php (No such file or directory)" while reading response header from upstream, client: 127.0.0.1, server: testapp.com, request: "GET / HTTP/1.1", upstream: "fastcgi://127.0.0.1:9000", host: "testapp.com" This baffles me because I have checked again and again and /www/app/www/index.php definitely exists! This is also validated by the fact that test.com/app/www/index.php works which means the file exists and the permissions are correct. Why is this happening and what are the root causes of things breaking for just the testapp.com v-host? Just an update to my investigation: I have commented out chroot and chdir in php-fpm.conf to narrow down the problem If I remove the location ~ \.php$ block for testapp.com, then nginx will send me a bin file which contains the PHP code. This means that on nginx's side, things are fine. The problem is that something must be mangling the file paths when passing it to PHP-FPM. Having said that, it is quite strange that the default_server v-host works fine because its root is /www, where as things just won't work for the testapp.com v-host because the root is /www/app/www.

  • How to recover data files from xampp-windows to xampp-linux after crash?

    - by David Buehler
    My Windows box died after I developed a database in xampp on it; fortunately I have a backup of the entire F:/TestWeb/Xampp partition. Unfortunately, I did not do an Export (nor dump) of the "Lws2" database before the crash. I have replaced the defunct machine with one running Mint7 (based on Ubuntu 9.04 "Jaunty Jackalope") and installed xampp-linux into the /opt partition, so the new xampp now runs fine in /opt/lampp, and says all the elements are secured by passwords (which I just assigned during this installation.) I assumed that Xamp-Windows installed in November would migrate easily to xampp-linux installed iin February -- a bad assumption. It apparently would have been simple if I had known enough to do an Export or a Dump before the crash, but.... The backup was done to a Network Attached Storage drive, which is formatted as "vfat" so the backup does not carry with it any valid ownership permissions from MySql on NTFS. I now see from my backup that the old data resided in \TestWeb\Xampp\Mysql\Data\Lws2\ and consists of 7 ".frm" files which define my tables. The actual data -- I suppose a ".sql" file or files -- has disappeared, and I am resigning myself to two days of retyping it. But I do not wish to do the table layouts all over again. So I copied Data tree to /opt/lampp/Data -- PhpMyAdmin does not see it. So I copied Lws2 tree to /opt/lampp/Lws2 -- PhpMyAdmin does not see it. So I copied Data tree to /opt/lampp/var/mysql/Data -- PhpMyAdmin does not see it. So I copied Lws2 tree to /opt/lampp/var/mysql/Lws2 -- PhpMyAdmin does not see it. So I adjusted all the permissions to stop saying owner "nobody" to owner "root" and gave full permissions to all groups and to all others, with permissions percolating down, in all 4 trees. You guessed it -- PhpMyAdmin does not see any database named Lws2, only its 4 default ones. I double-checked the permissions and rebooted Linux and repeated the tests. At some point in that process I did see PhpMyAdmin showing "lws2(7)" but when I clicked on it I saw a "no table found" message. I have not been able to recreate that experience. Apparently there are some setup files for MySql and for PhpMyAdmin which need to be set up by running a wizard or two or by editing the files directly. I grepped the TestWeb tree and found an old "ldir = "C:TestWeb\Xampp\MySql\" and a "DataDir = C:TestWeb\Xampp\MySql\" in a .php file and in a .bat file, but I cannot find the corresponding config file names on the /opt partition/ -- so it looks as if these wizards have not been run to create them. What config files files does Linux use to setup MySql config files for PhpMyAdmin? What wizards do I need to run to point the MySql engine and the PhpMyAdmin at the folder /opt/lampp/data/ with its lws2 folder inside it? Or which files do I need to edit, with a sample of what it normally says under Linux? Incidentally, I remember I converted from MyISAM with its .MYD and .MYI files to InnoDB after entering only a small amount of the data -- and I do not know what file types to look for -- perhaps my data is still there but under another guise or in another place? Is it something as simple as linux needing to see "/data/" instead of /Data? I will check that out while waiting for a response. If anyone can point me to documentation that discusses this level of detail -- I will read it avidly! In any case, thanks for any clarification you can give on this thorny problem. wizdum

  • nginx - 403 Forbidden

    - by michell90
    I've trouble to get aliases working correctly on nginx. When i try to access the aliases, /pma and /mba (see secure.example.com.conf), i get a 403 Forbidden but the base url works correctly. I read a lot of posts but nothing helped, so here i am. Nginx and php-fpm are running as www-data:www-data and the permissions for the directories are set to: drwxrwsr-x+ 5 www-data www-data 4.0K Dec 5 22:48 ./ drwxr-xr-x. 3 root root 4.0K Dec 4 22:50 ../ drwxrwsr-x+ 2 www-data www-data 4.0K Dec 5 13:10 mda.example.com/ drwxrwsr-x+ 11 www-data www-data 4.0K Dec 5 10:34 pma.example.com/ drwxrwsr-x+ 3 www-data www-data 4.0K Dec 5 11:49 www.example.com/ lrwxrwxrwx. 1 www-data www-data 18 Dec 5 09:56 secure.example.com -> www.example.com/ Im sorry for the bulk, but i thought better too much than too little.

  • Can I get advice on my nginx configuration (as a proxy in front of Jira and Confluence)?

    - by Nate
    I was wondering if I could get some advice on my nginx configuration. The config seems to be working, but I'm unsure if I'm doing everything properly. The basic idea is to have a Jira and Confluence server (in separate Tomcat instances) running on the same machine, with nginx in front to handle SSL for both. I want only SSL connections to be made to Jira/Confluence. Jira is running on 127.0.0.1:9090 and Confluence on 127.0.0.1:8080. Here is my nginx.conf, any advice or tips would be greatly appreciated. user nginx; worker_processes 1; error_log /var/log/nginx/error.log; pid /var/run/nginx.pid; events { worker_connections 1024; } http { include /etc/nginx/mime.types; default_type application/octet-stream; log_format main '$remote_addr - $remote_user [$time_local] $request ' '"$status" $body_bytes_sent "$http_referer" ' '"$http_user_agent" "$http_x_forwarded_for"'; access_log /var/log/nginx/access.log main; sendfile on; #tcp_nopush on; #keepalive_timeout 0; keepalive_timeout 65; #gzip on; # Load config files from the /etc/nginx/conf.d directory include /etc/nginx/conf.d/*.conf; # Our self-signed cert ssl_certificate /etc/ssl/certs/fissl.crt; ssl_certificate_key /etc/ssl/private/fissl.key; # redirect non-ssl Confluence to ssl server { listen 80; server_name confluence.example.com; rewrite ^(.*) https://confluence.example.com$1 permanent; } # redirect non-ssl Jira to ssl server { listen 80; server_name jira.example.com; rewrite ^(.*) https://jira.example.com$1 permanent; } # # The Confluence server # server { listen 443; server_name confluence.example.com; ssl on; access_log /var/log/nginx/confluence.access.log main; error_log /var/log/nginx/confluence.error.log; location / { proxy_pass http://127.0.0.1:8080; proxy_set_header X-Forwarded-Proto https; proxy_set_header Host $http_host; } error_page 404 /404.html; location = /404.html { root /usr/share/nginx/html; } redirect server error pages to the static page /50x.html error_page 500 502 503 504 /50x.html; location = /50x.html { root /usr/share/nginx/html; } } # # The Jira server # server { listen 443; server_name jira.example.com; ssl on; access_log /var/log/nginx/jira.access.log main; error_log /var/log/nginx/jira.error.log; location / { proxy_pass http://127.0.0.1:9090/; proxy_set_header X-Forwarded-Proto https; proxy_set_header Host $http_host; } error_page 404 /404.html; location = /404.html { root /usr/share/nginx/html; } # redirect server error pages to the static page /50x.html # error_page 500 502 503 504 /50x.html; location = /50x.html { root /usr/share/nginx/html; } } }

  • virtual host setup: can't access wordpress site without www

After installing everything, I get a 500 Internal server error. If I check logs, I see this: 012/09/27 08:55:54 [error] 11565#0: *8 rewrite or internal redirection cycle while internally redirecting to "/index.html", client: xxx.xxx.xxx.xxx, server: localhost, request: "GET /favicon.ico HTTP/1.1", host: "www.mydomain.com" 2012/09/27 08:59:32 [error] 11618#0: *1 rewrite or internal redirection cycle while internally redirecting to "/index.html", client: xxx.xxx.xxx.xxx, server: localhost, request: "GET /phpmyadmin HTTP/1.1", host: "www.mydomain.com" My conf files are the following: nano /etc/nginx/sites-available/mydomain.com server { listen 80 default_server; server_name mydomain.com *.mydomain.com; root /srv/www/aciup.com/public; access_log /srv/www/mydomain.com/log/access.log; error_log /srv/www/mydomain.com/log/error.log; location / { index index.php; try_files $uri $uri/ /index.php?$args; } # Add trailing slash to */wp-admin requests. rewrite /wp-admin$ $scheme://$host$uri/ permanent; # Directives to send expires headers and turn off 404 error logging. location ~* \.(js|css|png|jpg|jpeg|gif|ico)$ { expires 24h; log_not_found off; } # this prevents hidden files (beginning with a period) from being served location ~ /\. { access_log off; log_not_found off; deny all; } # Pass uploaded files to wp-includes/ms-files.php. rewrite /files/$ /index.php last; if ($uri !~ wp-content/plugins) { rewrite /files/(.+)$ /wp-includes/ms-files.php?file=$1 last; } # Rewrite multisite '.../wp-.*' and '.../*.php'. if (!-e $request_filename) { rewrite ^/[_0-9a-zA-Z-]+(/wp-.*) $1 last; rewrite ^/[_0-9a-zA-Z-]+.*(/wp-admin/.*\.php)$ $1 last; rewrite ^/[_0-9a-zA-Z-]+(/.*\.php)$ $1 last; } location ~ \.php$ { client_max_body_size 25M; fastcgi_pass unix:/var/run/php5-fpm.sock; fastcgi_index index.php; include /etc/nginx/fastcgi_params; } } nano /etc/nginx/nginx.conf user www-data; worker_processes 4; worker_cpu_affinity 0001 0010 0100 1000; error_log /var/log/nginx/error.log; pid /var/run/nginx.pid; events { worker_connections 2048; } http { include /etc/nginx/mime.types; access_log /var/log/nginx/access.log; sendfile on; tcp_nopush on; keepalive_timeout 5; tcp_nodelay on; server_tokens off; gzip on; gzip_types text/plain text/css application/x-javascript text/xml application/xml application/xml+rss text/javascript; gzip_disable "MSIE [1-6]\.(?!.*SV1)"; include /etc/nginx/conf.d/*.conf; include /etc/nginx/sites-enabled/*; } Any help will be appreciated.

  • How to place SuperFetch cache on an SSD?

    - by Ian Boyd
    I'm thinking of adding a solid state drive (SSD) to my existing Windows 7 installation. I know I can (and should) move my paging file to the SSD: Should the pagefile be placed on SSDs? Yes. Most pagefile operations are small random reads or larger sequential writes, both of which are types of operations that SSDs handle well. In looking at telemetry data from thousands of traces and focusing on pagefile reads and writes, we find that Pagefile.sys reads outnumber pagefile.sys writes by about 40 to 1, Pagefile.sys read sizes are typically quite small, with 67% less than or equal to 4 KB, and 88% less than 16 KB. Pagefile.sys writes are relatively large, with 62% greater than or equal to 128 KB and 45% being exactly 1 MB in size. In fact, given typical pagefile reference patterns and the favorable performance characteristics SSDs have on those patterns, there are few files better than the pagefile to place on an SSD. What I don't know is if I even can put a SuperFetch cache (i.e. ReadyBoost cache) on the solid state drive. I want to get the benefit of Windows being able to cache gigabytes of frequently accessed data on a relativly small (e.g. 30GB) solid state drive. This is exactly what SuperFetch+ReadyBoost (or SuperFetch+ReadyDrive) was designed for. Will Windows offer (or let) me place a ReadyBoost cache on a solid state flash drive connected via SATA? A problem with the ReadyBoost cache over the ReadyDrive cache is that the ReadyBoost cache does not survive between reboots. The cache is encrypted with a per-session key, making its existing contents unusable during boot and SuperFetch pre-fetching during login. Update One I know that Windows Vista limited you to only one ReadyBoost.sfcache file (I do not know if Windows 7 removed that limitation): Q: Can use use multiple devices for EMDs? A: Nope. We've limited Vista to one ReadyBoost per machine Q: Why just one device? A: Time and quality. Since this is the first revision of the feature, we decided to focus on making the single device exceptional, without the difficulties of managing multiple caches. We like the idea, though, and it's under consideration for future versions. I also know that the 4GB limit on the cache file was a limitation of the FAT filesystem used on most USB sticks - an SSD drive would be formatted with NTFS: Q: What's the largest amount of flash that I can use for ReadyBoost? A: You can use up to 4GB of flash for ReadyBoost (which turns out to be 8GB of cache w/ the compression) Q: Why can't I use more than 4GB of flash? A: The FAT32 filesystem limits our ReadyBoost.sfcache file to 4GB Can a ReadyBoost cache on an NTFS volume be larger than 4GB? Update Two The ReadyBoost cache is encrypted with a per-boot session key. This means that the cache has to be re-built after each boot, and cannot be used to help speed boot times, or latency from login to usable. Windows ReadyDrive technology takes advantage of non-volatile (NV) memory (i.e. flash) that is incorporated with some hybrid hard drives. This flash cache can be used to help Windows boot, or resume from hibernate faster. Will Windows 7 use an internal SSD drive as a ReadyBoost/*ReadyDrive*/SuperFetch cache? Is it possible to make Windows store a SuperFetch cache (i.e. ReadyBoost) on a non-removable SSD? Is it possible to not encrypt the ReadyBoost cache, and if so will Windows 7 use the cache at boot time? See also SuperUser.com: ReadyBoost + SSD = ? Windows 7 - ReadyBoost & SSD drives?

  • Why are my httpd mpm_prefork processes being reaped so quickly?

    - by Dan Pritts
    We've got a system running RHEL6, x64. We are using a local installation of apache 2.2.22 from source. we serve primarily: mod_perl applications (with a local installation of perl 5.16.0) tomcat applications proxied with mod_jk Here is some context; the main question is below. All of this talks to an Oracle backend. We are having issues with Oracle becoming unresponsive. We think this is because we're hitting the maximum process limit in oracle. We've upped the process limit, but now we are hitting memory pressure on the oracle server. We have tons of oracle sessions sitting idle. I can trace a bunch of them back to the httpd processes. We have mod_perl's Apache::DBI start up a new connection to the database with each httpd child that's spawned. We are concerned that these are not always getting closed out properly when the httpd's exit...and the httpd's are exiting very frequently. I know that it would be good to modify the mod_perl applications to use some better form of db connection pooling; we plan to pursue that but would like to solve our immediate problem sooner. So here's the main question. We are using the prefork MPM. The apache child processes are lasting at most a few minutes. Log analysis shows that each one is serving fewer than 50 clients before exiting; the last request each child serves is OPTIONS * HTTP/1.0 on some sort of internal connection; I'm under the impression that this is a "ping" from the master process. I've adjusted the MPM config as follows. I didn't want to raise MinSpareServers too high, because, after all, i'm trying to minimize the number of sessions to oracle. MinSpareServers 5 MaxSpareServers 30 MaxClients 150 MaxRequestsPerChild 10000 Right now we're serving 250-300 requests per minute. We've got 21 httpd's running, the eldest (other than the master, owned by root) being 3 minutes old. This rate of reaping of the apache children really seems excessive. What could be causing it? Apache was built with: $ ./configure --prefix=/opt/apache --with-ssl=/usr/lib --enable-expires --enable-ext-filter --enable-info --enable-mime-magic --enable-rewrite --enable-so --enable-speling --enable-ssl --enable-usertrack --enable-proxy --enable-headers --enable-log-forensic Apache config info: % /opt/apache/bin/httpd -V Server version: Apache/2.2.22 (Unix) Server built: Jul 23 2012 22:30:13 Server's Module Magic Number: 20051115:30 Server loaded: APR 1.4.5, APR-Util 1.4.1 Compiled using: APR 1.4.5, APR-Util 1.4.1 Architecture: 64-bit Server MPM: Prefork threaded: no forked: yes (variable process count) Server compiled with.... -D APACHE_MPM_DIR="server/mpm/prefork" -D APR_HAS_SENDFILE -D APR_HAS_MMAP -D APR_HAVE_IPV6 (IPv4-mapped addresses enabled) -D APR_USE_SYSVSEM_SERIALIZE -D APR_USE_PTHREAD_SERIALIZE -D SINGLE_LISTEN_UNSERIALIZED_ACCEPT -D APR_HAS_OTHER_CHILD -D AP_HAVE_RELIABLE_PIPED_LOGS -D DYNAMIC_MODULE_LIMIT=128 -D HTTPD_ROOT="/opt/apache" -D SUEXEC_BIN="/opt/apache/bin/suexec" -D DEFAULT_PIDLOG="logs/httpd.pid" -D DEFAULT_SCOREBOARD="logs/apache_runtime_status" -D DEFAULT_LOCKFILE="logs/accept.lock" -D DEFAULT_ERRORLOG="logs/error_log" -D AP_TYPES_CONFIG_FILE="conf/mime.types" -D SERVER_CONFIG_FILE="conf/httpd.conf" modules are compiled into apache rather than shared libs: % /opt/apache/bin/httpd -l Compiled in modules: core.c mod_authn_file.c mod_authn_default.c mod_authz_host.c mod_authz_groupfile.c mod_authz_user.c mod_authz_default.c mod_auth_basic.c mod_ext_filter.c mod_include.c mod_filter.c mod_log_config.c mod_log_forensic.c mod_env.c mod_mime_magic.c mod_expires.c mod_headers.c mod_usertrack.c mod_setenvif.c mod_version.c mod_proxy.c mod_proxy_connect.c mod_proxy_ftp.c mod_proxy_http.c mod_proxy_scgi.c mod_proxy_ajp.c mod_proxy_balancer.c mod_ssl.c prefork.c http_core.c mod_mime.c mod_status.c mod_autoindex.c mod_asis.c mod_info.c mod_cgi.c mod_negotiation.c mod_dir.c mod_actions.c mod_speling.c mod_userdir.c mod_alias.c mod_rewrite.c mod_so.c One final note - the red hat httpd, apr, and perl packages are all installed, but ldd shows that none of those libraries are linked with the running httpd.

  • nginx serving php for download (previously: nginx multiple location alias 404)

    - by torsten
    Im having issues with the alias location in the following configuration server { listen 80; server_name localhost; root /srv/http/share; index index.php; include php.conf; location / { try_files $uri $uri/ /index.php$is_args$args; } location /phpmemcachedadmin { alias /srv/http/phpmemcachedadmin; } location /webgrind { alias /srv/http/webgrind; } } while / works well, im getting a 404 for /webgrind and /phpmemcachedadmin. If i switch the root directory to /srv/http and alias the / location, die /phpmemcachedadmin and webgrind work, but not the / location. UPDATE: I managed the probems getting all location to work, so here is the updated config #user html; worker_processes 2; #error_log logs/error.log; #error_log logs/error.log notice; #error_log logs/error.log info; #pid logs/nginx.pid; events { worker_connections 1024; } http { include mime.types; default_type application/octet-stream; sendfile on; keepalive_timeout 65; gzip on; server { listen 80; server_name localhost; location / { root /srv/http/share; index index.php; try_files $uri $uri/ /index.php$is_args$args; include php.conf; } location /phpmemcachedadmin { root /srv/http; index index.php; try_files $uri $uri/ /index.php$is_args$args; include php.conf; } location /webgrind { root /srv/http; index index.php; try_files $uri $uri/ /index.php$is_args$args; include php.conf; } } } The php.conf looks like this: location ~ \.php$ { try_files $uri =404; fastcgi_pass unix:/run/php-fpm/php-fpm.sock; fastcgi_index index.php; include fastcgi.conf; } while the fastcgi.conf like this: fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name; fastcgi_param QUERY_STRING $query_string; fastcgi_param REQUEST_METHOD $request_method; fastcgi_param CONTENT_TYPE $content_type; fastcgi_param CONTENT_LENGTH $content_length; fastcgi_param SCRIPT_NAME $fastcgi_script_name; fastcgi_param REQUEST_URI $request_uri; fastcgi_param DOCUMENT_URI $document_uri; fastcgi_param DOCUMENT_ROOT $document_root; fastcgi_param SERVER_PROTOCOL $server_protocol; fastcgi_param HTTPS $https if_not_empty; fastcgi_param GATEWAY_INTERFACE CGI/1.1; fastcgi_param SERVER_SOFTWARE nginx/$nginx_version; fastcgi_param REMOTE_ADDR $remote_addr; fastcgi_param REMOTE_PORT $remote_port; fastcgi_param SERVER_ADDR $server_addr; fastcgi_param SERVER_PORT $server_port; fastcgi_param SERVER_NAME $server_name; # PHP only, required if PHP was built with --enable-force-cgi-redirect fastcgi_param REDIRECT_STATUS 200; But there is a problem serving phpmemcachedadmin. If i call localhost/phpmemcachedadmin/index.php it works quite well (i get a log that i got served the file in access log). On the other hand, if i just call localhost/phpmemcachedadmin/ he serves me the file for download. Neither the error.log nor the access.log log anything when i get served the the file for download. Any ideas?

  • Unable to remove limit on memory usage for PHP script.

    - by Jess Telford
    The Situation I am having an issue with a PHP script getting the following error message: Fatal error: Out of memory (allocated 359923712) (tried to allocate 72 bytes) in /path/to/piwik/core/DataTable.php on line 969 The script I'm running is: /path/to/piwik/misc/cron/archive.sh I am assuming the numbers are Bytes, which means that total is approximately 360MB. For all intents and purposes, I have increased the memory limits on the server well above 360MB, yet this is the number (give or take a byte) it consistently errors out at. Please note: This question is not about fixing a memory leak in the script, nor about why the script itself is using so much memory. The script is part of the Piwik archiving process, so I cannot just fix any memory leaks, etc. For more info on this script and why I am increasing the memory limit, see "How to setup auto archiving" The question Given that the script is attempting to use over 360MB of memory, which I cannot change, why does it not seem possible for me to increase the amount of memory available to php on my server? What I've tried Increasing PHP's memory_limit Given the php.ini file: php -i | grep php.ini Configuration File (php.ini) Path => /usr/local/lib Loaded Configuration File => /usr/local/lib/php.ini I have edited that file, so the memory_limit directive reads; memory_limit = -1 Restart Apache, and check the new value has stuck; $ php -i | grep memory_limit memory_limit => -1 => -1 Run the script, and get the same error. I've also tried 1G, 768M, etc, all to the same result (ie; no change). Update 22nd June: Based on Vangel's help, I have attempted to set post_max_size to 20M in combination with setting memory_limit. Again, this has no effect. Removing the memory limit on child processes of Apache I have found and edited the httpd.conf file to make sure there is no RLimitMEM directive. I then used WHM's Apache Configuration Memory Usage Restrictions to generate a restriction, which it claimed was at 1000M (and confirmed by checking httpd.conf). Both of these resulted in no change to the script erroring at 360MB. Increasing the per process memory limits of Linux The current limits set on the system: $ ulimit -m 524288 $ ulimit -v 524288 I have attempted to set both of these to unlimited: $ ulimit -m unlimited $ ulimit -v unlimited $ ulimit -m unlimited $ ulimit -v unlimited Once again, this has resulted in absolutely no improvement in my problem. My setup $ cat /etc/redhat-release CentOS release 5.5 (Final) $ uname -a Linux example.com 2.6.18-164.15.1.el5 #1 SMP Wed Mar 17 11:30:06 EDT 2010 x86_64 x86_64 x86_64 GNU/Linux $ php -i | grep "PHP Version" PHP Version => 5.2.9 $ httpd -V Server version: Apache/2.0.63 Server built: Feb 2 2011 01:25:12 Cpanel::Easy::Apache v3.2.0 rev5291 Server's Module Magic Number: 20020903:13 Server loaded: APR 0.9.17, APR-UTIL 0.9.15 Compiled using: APR 0.9.17, APR-UTIL 0.9.15 Architecture: 64-bit Server compiled with.... -D APACHE_MPM_DIR="server/mpm/prefork" -D APR_HAS_SENDFILE -D APR_HAS_MMAP -D APR_HAVE_IPV6 (IPv4-mapped addresses enabled) -D APR_USE_SYSVSEM_SERIALIZE -D APR_USE_PTHREAD_SERIALIZE -D SINGLE_LISTEN_UNSERIALIZED_ACCEPT -D APR_HAS_OTHER_CHILD -D AP_HAVE_RELIABLE_PIPED_LOGS -D HTTPD_ROOT="/usr/local/apache" -D SUEXEC_BIN="/usr/local/apache/bin/suexec" -D DEFAULT_PIDLOG="logs/httpd.pid" -D DEFAULT_SCOREBOARD="logs/apache_runtime_status" -D DEFAULT_LOCKFILE="logs/accept.lock" -D DEFAULT_ERRORLOG="logs/error_log" -D AP_TYPES_CONFIG_FILE="conf/mime.types" -D SERVER_CONFIG_FILE="conf/httpd.conf" Output of $ php -i: http://pastebin.com/EiRut6Nm
