• Restart a single apache vhost

  - by snowflake

  I've got an Apache (2) server with several virtual hosts. I currently have mysql db locks problems on one virtual host. A common and practical way to easy release those locks and unlock the site (while the dev team refactor its application to avoid the locks), is to simply restart the apache server. I'm wondering if there is a way to restart the single vhost that is in trouble. Thank you for any comments

• Host couldn't be reached by domain name, only by IP: Apache's fault?

  - by MaxArt

  I have this Windows Server 2003 R2 32 bit machine running Apache 2.4.2 with OpenSSL 1.0.1c and PHP 5.4.5 via mod_fcgid 2.3.7. This config worked just fine for some hours, but then the site couldn't be reached with its domain name, say www.example.com, but it could be still reached by its IP address. In particular, while https://www.example.com/ yielded a connection error, http://123.1.2.3/ worked just fine. Yes, first https then http. Error and access logs were clean, i.e. they showed no signs of problems. Just the usual messages, that were interrupted while the site couldn't be reached. After some investigation, a simple restart of Apache solved the problem. Unfortunately, I didn't have the chance to test if https://123.1.2.3/ worked as well, or if http://www.example.com/ was still redirected to https as usual. So, has anyone have any idea of what happened? Before I get tired of Apache and ditch it in favor of Nginx? Edit: Some log informations. The last line of sslerror.log is from 90 minutes before the problem occurred, so I guess it's not important. ssl_request.log shows nothing interesting, too: these are the last two lines before the problem: [28/Aug/2012:17:47:54 +0200] x.x.x.x TLSv1.1 ECDHE-RSA-AES256-SHA "GET /login HTTP/1.1" 1183 [28/Aug/2012:17:47:45 +0200] y.y.y.y TLSv1 ECDHE-RSA-AES256-SHA "POST /upf HTTP/1.1" 73 The previous lines are all the same and don't seem interesting, except 4 lines like these 30-40 seconds before the problem: [28/Aug/2012:17:47:14 +0200] z.z.z.z TLSv1 ECDHE-RSA-AES256-SHA "-" - These are the corrisponding lines from sslaccess.log: z.z.z.z - - [28/Aug/2012:17:47:14 +0200] "-" 408 - ... x.x.x.x - - [28/Aug/2012:17:47:54 +0200] "GET /login HTTP/1.1" 200 1183 y.y.y.y - - [28/Aug/2012:17:47:45 +0200] "POST /upf HTTP/1.1" 200 73

• How to config PHP libxml path after updated libxml from 2.2.26 to 2.9

  - by Cauliturtle

  our servers need to update the libxml2 version from 2.2.26 to 2.9 (latest version). It is no problem that we have been installed the libxml2-2.9 version on our servers. but the problem is how can we config the libs path of libxml2 path in php? Since it still show the old version on phpinfo(). What we have do is 1. Install libxml2 2.7.X on CentOS 5.X Using yum to install local files, and typed yum info libxml2, it shows 2.9 was installed. Thanks!

• Nginx, proxy passing to Apache, and SSL

  - by Vic

  I have Nginx and Apache set up with Nginx proxy-passing everything to Apache except static resources. I have a server set up for port 80 like so: server { listen 80; server_name *.example1.com *.example2.com; [...] location ~* \.(?:ico|css|js|gif|jpe?g|png|pdf|te?xt)$ { access_log off; expires max; add_header Pragma public; add_header Cache-Control "public, must-revalidate, proxy-revalidate"; add_header Vary: Accept-Encoding; } location / { proxy_pass http://127.0.0.1:8080; include /etc/nginx/conf.d/proxy.conf; } } And since we have multiple ssl sites (with different ssl certificates) I have a server{} block for each of them like so: server { listen 443 ssl; server_name *.example1.com; [...] location ~* \.(?:ico|css|js|gif|jpe?g|png|pdf|te?xt)$ { access_log off; expires max; add_header Pragma public; add_header Cache-Control "public, must-revalidate, proxy-revalidate"; add_header Vary: Accept-Encoding; } location / { proxy_pass https://127.0.0.1:8443; include /etc/nginx/conf.d/proxy.conf; proxy_set_header X-Forwarded-Port 443; proxy_set_header X-Forwarded-Proto https; } } server { listen 443 ssl; server_name *.example2.com; [...] location ~* \.(?:ico|css|js|gif|jpe?g|png|pdf|te?xt)$ { access_log off; expires max; add_header Pragma public; add_header Cache-Control "public, must-revalidate, proxy-revalidate"; add_header Vary: Accept-Encoding; } location / { proxy_pass https://127.0.0.1:8445; include /etc/nginx/conf.d/proxy.conf; proxy_set_header X-Forwarded-Port 443; proxy_set_header X-Forwarded-Proto https; } } First of all, I think there is a very obvious problem here, which is that I'm double-encrypting everything, first at the nginx level and then again by Apache. To make everything worse, I just started using Amazon's Elastic Load Balancer, so I added the certificate to the ELB and now SSL encryption is happening three times. That's gotta be horrible for performance. What is the sane way to handle this? Should I be forwarding https on the ELB - http on nginx - http on apache? Secondly, there is so much duplication above. Is the best method to not repeat myself to put all of the static asset handling in an include file and just include it in the server?

• Protect all XML-RPC calls with HTTP basic auth but one

  - by bodom_lx

  I set up a Django project for smartphone serving XML-RPC methods over HTTPS and using basic auth. All XML-RPC methods require username and password. I would like to implement a XML-RPC method to provide registration to the system. Obviously, this method should not require username and password. The following is the Apache conf section responsible for basic auth: <Location /RPC2> AuthType Basic AuthName "Login Required" Require valid-user AuthBasicProvider wsgi WSGIAuthUserScript /path/to/auth.wsgi </Location> This is my auth.wsgi: import os import sys sys.stdout = sys.stderr sys.path.append('/path/to/project') os.environ['DJANGO_SETTINGS_MODULE'] = 'project.settings' from django.contrib.auth.models import User from django import db def check_password(environ, user, password): """ Authenticates apache/mod_wsgi against Django's auth database. """ db.reset_queries() kwargs = {'username': user, 'is_active': True} try: # checks that the username is valid try: user = User.objects.get(**kwargs) except User.DoesNotExist: return None # verifies that the password is valid for the user if user.check_password(password): return True else: return False finally: db.connection.close() There are two dirty ways to achieve my aim with current situation: Have a dummy username/password to be used when trying to register to the system Have a separate Django/XML-RPC application on another URL (ie: /register) that is not protected by basic auth Both of them are very ugly, as I would also like to define a standard protocol to be used for services like mine (it's an open Dynamic Ridesharing Architecture) Is there a way to unprotect a single XML-RPC call (ie. a defined POST request) even if all XML-RPC calls over /RPC2 are protected?

• duplicate cache pages: Varnish

  - by Sukhjinder Singh

  Recently we have configured Varnish on our server, it was successfully setup but we noticed that if we open any page in multiple browsers, the Varnish send request to Apache not matter page is cached or not. If we refresh twice on each browser it creates duplicate copies of the same page. What exactly should happen: If any page is cached by Varnish, the subsequent request should be served from Varnish itself when we are opening the same page in browser OR we are opening that page from different IP address. Following is my default.vcl file backend default { .host = "127.0.0.1"; .port = "80"; } sub vcl_recv { if( req.url ~ "^/search/.*$") { }else { set req.url = regsub(req.url, "\?.*", ""); } if (req.restarts == 0) { if (req.http.x-forwarded-for) { set req.http.X-Forwarded-For = req.http.X-Forwarded-For + ", " + client.ip; } else { set req.http.X-Forwarded-For = client.ip; } } if (!req.backend.healthy) { unset req.http.Cookie; } set req.grace = 6h; if (req.url ~ "^/status\.php$" || req.url ~ "^/update\.php$" || req.url ~ "^/admin$" || req.url ~ "^/admin/.*$" || req.url ~ "^/flag/.*$" || req.url ~ "^.*/ajax/.*$" || req.url ~ "^.*/ahah/.*$") { return (pass); } if (req.url ~ "(?i)\.(pdf|asc|dat|txt|doc|xls|ppt|tgz|csv|png|gif|jpeg|jpg|ico|swf|css|js)(\?.*)?$") { unset req.http.Cookie; } if (req.http.Cookie) { set req.http.Cookie = ";" + req.http.Cookie; set req.http.Cookie = regsuball(req.http.Cookie, "; +", ";"); set req.http.Cookie = regsuball(req.http.Cookie, ";(SESS[a-z0-9]+|SSESS[a-z0-9]+|NO_CACHE)=", "; \1="); set req.http.Cookie = regsuball(req.http.Cookie, ";[^ ][^;]*", ""); set req.http.Cookie = regsuball(req.http.Cookie, "^[; ]+|[; ]+$", ""); if (req.http.Cookie == "") { unset req.http.Cookie; } else { return (pass); } } if (req.request != "GET" && req.request != "HEAD" && req.request != "PUT" && req.request != "POST" && req.request != "TRACE" && req.request != "OPTIONS" && req.request != "DELETE") {return(pipe);} /* Non-RFC2616 or CONNECT which is weird. */ if (req.request != "GET" && req.request != "HEAD") { return (pass); } if (req.http.Accept-Encoding) { if (req.url ~ "\.(jpg|png|gif|gz|tgz|bz2|tbz|mp3|ogg)$") { # No point in compressing these remove req.http.Accept-Encoding; } else if (req.http.Accept-Encoding ~ "gzip") { set req.http.Accept-Encoding = "gzip"; } else if (req.http.Accept-Encoding ~ "deflate") { set req.http.Accept-Encoding = "deflate"; } else { # unknown algorithm remove req.http.Accept-Encoding; } } return (lookup); } sub vcl_deliver { if (obj.hits > 0) { set resp.http.X-Varnish-Cache = "HIT"; } else { set resp.http.X-Varnish-Cache = "MISS"; } } sub vcl_fetch { if (beresp.status == 404 || beresp.status == 301 || beresp.status == 500) { set beresp.ttl = 10m; } if (req.url ~ "(?i)\.(pdf|asc|dat|txt|doc|xls|ppt|tgz|csv|png|gif|jpeg|jpg|ico|swf|css|js)(\?.*)?$") { unset beresp.http.set-cookie; } set beresp.grace = 6h; } sub vcl_hash { hash_data(req.url); if (req.http.host) { hash_data(req.http.host); } else { hash_data(server.ip); } return (hash); } sub vcl_pipe { set req.http.connection = "close"; } sub vcl_hit { if (req.request == "PURGE") {ban_url(req.url); error 200 "Purged";} if (!obj.ttl > 0s) {return(pass);} } sub vcl_miss { if (req.request == "PURGE") {error 200 "Not in cache";} }

• APC PHP cache size does not exceed 32MB, even though settings allow for more

  - by hardy101

  I am setting up APC (v 3.1.9) on a high-traffic WordPress installation on CentOS 6.0 64 bit. I have figured out many of the quirks with APC, but something is still not quite right. No matter what settings I change, APC never actually caches more than 32MB. I'm trying to bump it up to 256 MB. 32MB is a default amount for apc.shm_size, so I am wondering if it's stuck there somehow. I have run the following echo '2147483648' > /proc/sys/kernel/shmmax to increase my system's shared memory to 2G (half of my 4G box). Then ran ipcs -lm which returns ------ Shared Memory Limits -------- max number of segments = 4096 max seg size (kbytes) = 2097152 max total shared memory (kbytes) = 8388608 min seg size (bytes) = 1 Also made a change in /etc/sysctl.conf then ran sysctl -p to make the settings stick on the server. Rebooted, too, for good measure. In my APC settings, I have mmap enabled (which happens by default in recent versions of APC). php.ini looks like: apc.stat=0 apc.shm_size="256M" apc.max_file_size="10M" apc.mmap_file_mask="/tmp/apc.XXXXXX" apc.ttl="7200" I am aware that mmap mode will ignore references to apc.shm_segments, so I have left it out with default 1. phpinfo() indicates the following about APC: Version 3.1.9 APC Debugging Disabled MMAP Support Enabled MMAP File Mask /tmp/apc.bPS7rB Locking type pthread mutex Locks Serialization Support php Revision $Revision: 308812 $ Build Date Oct 11 2011 22:55:02 Directive Local Value apc.cache_by_default On apc.canonicalize O apc.coredump_unmap Off apc.enable_cli Off apc.enabled On On apc.file_md5 Off apc.file_update_protection 2 apc.filters no value apc.gc_ttl 3600 apc.include_once_override Off apc.lazy_classes Off apc.lazy_functions Off apc.max_file_size 10M apc.mmap_file_mask /tmp/apc.bPS7rB apc.num_files_hint 1000 apc.preload_path no value apc.report_autofilter Off apc.rfc1867 Off apc.rfc1867_freq 0 apc.rfc1867_name APC_UPLOAD_PROGRESS apc.rfc1867_prefix upload_ apc.rfc1867_ttl 3600 apc.serializer default apc.shm_segments 1 apc.shm_size 256M apc.slam_defense On apc.stat Off apc.stat_ctime Off apc.ttl 7200 apc.use_request_time On apc.user_entries_hint 4096 apc.user_ttl 0 apc.write_lock On apc.php reveals the following graph, no matter how long the server runs (cache size fluctuates and hovers at just under 32MB. See image http://i.stack.imgur.com/2bwMa.png You can see that the cache is trying to allocate 256MB, but the brown piece of the pie keeps getting recycled at 32MB. This is confirmed as refreshing the apc.php page shows cached file counts that move up and down (implying that the cache is not holding onto all of its files). Does anyone have an idea of how to get APC to use more than 32 MB for its cache size?? **Note that the identical behavior occurs for eaccelerator, xcache, and APC. I read here: http://www.litespeedtech.com/support/forum/archive/index.php/t-5072.html that suEXEC could cause this problem.

• Enforcing a specific order for cookie headers

  - by Paul

  We have an application that cares about the order of cookie headers. It shouldn't, since this isn't mandated by the standards and indeed we're getting the headers in various different orders So we would like to rewrite the headers in Apache so that the cookie headers always appear in a specific order. Is there any way of doing this? An ideal solution would be specifically about cookie headers, but something that lets us mess with the header order more generally would do too.

• Fatal error: Out of memory (allocated ...) (tried to allocate ... bytes) not due to memory_limit setting

  - by Lorenz Meyer

  Since a few days, I get the following error on my server: Fatal error: Out of memory (allocated 262144) (tried to allocate 393216 bytes) Usually this error is due to a memory consumption that is exceeding the configured memory_limit, but in my case there is no relation. The memory_limit is set to 128MB, and in this case, we not even reach 1MB. Also the server does not have a big load, in fact it is an intranet server, and there are just a few people conected to it. System: Windows Server 2003, 1Go RAM, only 600 MB used. Apache 2.2.4 PHP 5.2.3 This error is appearing randomly. The memory limit reached also is randomly between a few kB to a few MB. Sometimes restarting Apache is required to get rid of the error, sometimes it disapears itself. Restarting Apache or the entire server helps temporarily. Where could this problem come from ? How could I narrow down the error source ?

• 403 Error when accessing vhost directive

  - by Ortix92

  I'm having some troubles with setting up my webserver (Centos 5.8). It's a brand new server and I'm trying to set a vhost to the following dir: /home/exo/public_html However whenever I restart httpd I get the following warning: Code: Starting httpd: Warning: DocumentRoot [/home/exo/public_html] does not exist Yes the directory does exist. So whenever I visit the domain exo-l.com it gives me a 403 error. This is my config file (I put this inside my httpd.conf because the files in conf.d were not included for some reason. Or at least my newly created vhost conf file, but that has 0 priority for now) <VirtualHost *:80> DocumentRoot /home/exo/public_html ServerName www.exo-l.com ServerAlias exo-l.com <Directory /home/exo/public_html> Order allow,deny Allow from all </Directory> </VirtualHost I'm completely clueless because this should work as far as I know. httpd is being run as apache:apache i tried chowning the public_html directory (also recursively) to exo:apache, apache:apache, root:root with no success. chmod 777 doesn't do anything either. a tail from the log: [Sat Oct 13 15:10:04 2012] [error] [client 82.***.***.61] (13)Permission denied: access to / denied [Sat Oct 13 15:10:04 2012] [error] [client 82.***.***.61] (13)Permission denied: access to / denied I also found something about selinux and that disabling it might help, but do I really want to do that?

• How Do I Use Multiple Versions of OpenSSL ... One for Apache and one for PHP

  - by Ken S.

  I have an Apache 2.2 (self-compiled version) server that is getting dinged during a PCI scan because it does not support TLS 1.1 or 1.2 ciphers. After some digging I found that the installed version of OpenSSL (0.9.8e) does not contain the newest TLS ciphers. So I went and downloaded and compiled the latest version of OpenSSL (1.0.1c) and have it installed in an alternate location within /opt so it wouldn't interfere with the installed version. What I would like to do is to compile Apache against the 1.0.1 libraries and keep the system-installed libraries for use with PHP, cURL, openssh, etc. I'm hoping that doing it this way will allow Apache to use the newest TLS but not break anything with any other programs that require the old libraries. I thought I could do this by adding an entry in to /etc/ld.so.conf that pointed to the new libraries, but I think this will conflict with the existing ones. i.e. two references to libcrypto could cause everything to have issues. The main reason for doing this is because of issues with PHP cURLing to external servers and having issues with the latest OpenSSL libs thus requiring edits to our PHP code. Would love some guidance on how best to accomplish this.

• Retrieve malicious IP addresses from Apache logs and block them with iptables

  - by Gabriel Talavera

  Im trying to keep away some attackers that try to exploit XSS vulnerabilities from my website, I have found that most of the malicious attempts start with a classic "alert(document.cookie);\" test. The site is not vulnerable to XSS but I want to block the offending IP addresses before they found a real vulnerability, also, to keep the logs clean. My first thought is to have a script constantly checking in the Apache logs all IP addresses that start with that probe and send those addresses to an iptables drop rule. With something like this: cat /var/log/httpd/-access_log | grep "alert(document.cookie);" | awk '{print $1}' | uniq Why would be an effective way to send the output of that command to iptables? Thanks in advance for any input!

• Nginx proxy to Apache - resolve HTTP ORIGIN

  - by Fratyr

  I have a server setup with nginx serving static content and proxy all PHP/dynamic requests to apache on 127.0.0.1 I'm building an API for my databases, and I need to allow clients by their origin (domain name), rather than just IP. Based on CORS rules. So when I send an HTTP header header("Access-Control-Allow-Origin: www.client-requesting.myapi.com"); from my API server, I have to tell it which origin I allow, otherwise client side requests won't work to my API due to same-origin policy. The question is how can I know which domain name (if any) called my API? What should be the nginx and apache configuration to pass the origin parameter? I tried to google, and all I found is some possible solution with mod_rpaf, but I wanted to be sure. Thanks!

• reverse proxy http to tomcat

  - by John Q

  I've configured an Apache server with SSL and reverse proxy to a tomcat <VirtualHost domain.com:1443> [...] ProxyRequests Off ProxyPreserveHost On ProxyPass / http://local.com:8080/ ProxyPassReverse / http://local.com:8080 SSLEngine on [...] </VirtualHost> Tomcat is listening on 8080. The issue is that the app on tomcat is redirecting the request (HTTP 302 Moved temporairly). For example, if I use the URL https:// domain.com:1443/folder, reverse proxy launch the request http:// local.com:8080/folder, then, the app redirect to "/subfolder", so the final request is: http://domain.com:1443/folder/subfolder. Result is a 400 Bad request error code, as the request is HTTP on my SSL port. Do you know how I can fix this issue ? Thanks in advance.

• How to setup Wordpress High Availability

  - by Ketam

  I have installed Galera Cluster on 3 cluster + 1 management. I wanted to make it like this, Server1: Home (www.domain.com) Server2: For BBpress/Forum (Forum Tab Menu will forward to forum.domain.com) Server3: BuddyPress Activity (Social Tab Menu will forward to social.domain.com) The purpose I am doing this is to distribute my resource and load balancing each other at same time. However, I have difficulty to setup Apache Load-Balancing/mod_proxy/clustering or any suitable to have high availability WordPress. Any best suggestion/solution to make high availability WordPress? Or how to? And another question is I tried to copy whole WordPress files & folders to Server2 connecting to local database (same data inside since it is already on Galera Cluster) but the page blank. Any advice? OS: Centos 6.2 Thanks in advanced.

• Amazon EC2: Instances, IPs and a wordpress blog (LAMP)

  - by JustinXXVII

  I had a link to my blog posted on Reddit yesterday and MySQL crashed on my EC2 Micro instance. I know I didn't have that many visitors because I used a marketing link that tracks hits. The link got 167 hits over the course of the last 18 hours, and MySQL crashed twice. So anyway, 167 visits is not a lot, so I've done some short term optimizations like restricting the number of Apache threads to limit the MySQL calls. I also set up WP Super Cache to serve static content. Soon I'm going to offload all of my images to S3 or CloudFront. So this leads me to my question. If this doesn't seem to help, and if i have another traffic "spike", how do AMIs work when you have a MySQL database? I think I understand that if you have more than one instance and assign the same Elastic IP to both of them, the incoming traffic gets distributed among both. But what happens when the MySQL database gets updated on one of the instances? I just need to wrap my mind around what happens when I create an AMI and then launch a new instance to help with traffic. Thanks for your suggestions.

• How can I setup BluePill to Monitor a Rails App Running via Passenger (mod_rails)

  - by Jim Jeffers

  I recently launched a site running phusion passenger. Unfortunately, the site went down due to a frozen thread. I was able to save the server by doing kill -9 to the specific PID. Still though, I thought passenger was able to manage this automatically. I have a server with 1GB of memory running one rails app with passenger allotted up to 7 instances. However, when I came to discover the site went down I found that passenger had spawned 6 instances with one of them using up over 800mb of memory causing the server to swap. As a result I am hoping to setup something like bluepill on the server but I'm slightly confused as to how you go about doing it. Mainly because bluepill expects to start/stop the processes it's monitoring. However, in our case, passenger already restarts processes for us so we only need to monitor the pids of passengers instances and kill them once they've gotten too large. Has anyone here setup BluePill to monitor a rails app running under phusion's passenger? Any insight would be useful.

• .htaccess deny from all does not work?

  - by jeffery_the_wind

  I am running Apache 2.2.20 on a Ubuntu 11.04 web server. I have a Joomla site running on it, but I have also added some custom content. In the main web directly I have added a folder /images/sub_folder and in this sub_folder I have put a bunch of pictures. I do not want anyone to be able to simply access these pictures directly from the web, so I made a .htaccess file in that sub_folder and just put the following line in it: deny from all There doesn't seem to be any effect, I can still access the images directly from a web browser. I have restarted the Apache service. What am I doing wrong? Thanks Tim

• Flush mod_pagespeed cache in Debian

  - by Ivar

  I need a way to flush the mod_pagespeed cache while developing. According to mod_pagespeed documents, I should run the following command: sudo touch /var/mod_pagespeed/cache/cache.flush In Debian it's "su" instead of "sudo". However, it doesn't work for me; there's no "touch" command, nor is there any "cache.flush" file in the defined directory. Have I missed something? You kick-ass Linux users, please be humble - I'm pretty new to these stuff. Thank you in advance!

• What are the risks in putting website files in the "root" folder of a shared web hosting server?

  - by Obay Ouano

  A site I've been asked to manage is hosted (shared) on GoDaddy, with this folder structure: / public_html public_ftp mail stats logs etc... However, the website files are stored in the / folder, and NOT in public_html. I'm not sure if this is how GoDaddy sets up their customers' accounts, or if the old web developer accidentally changed it from public_html to root. But when we call up GoDaddy to tell them to correct this (move files to public_html), they won't change it and insist that there is no security risk unless someone gets a hold of the FTP password. Is this true? (I have always read that website files should be inside public_html.) If not, where could this setting be changed? The .htaccess is empty.
