nginx connection pool race condition?

- by wlf

I have a shared hosting server with high traffic. I have a lightweight apache mod_proxy for static content that from time to time has a "504 proxy error" problem proxing to apache/mod_php. Error log says: error reading status line from remote server 127.0.0.1:8080 Error reading from remote server returned by / This is what the apache documentation says about it. proxy-initial-not-pooled If this variable is set no pooled connection will be reused if the client connection is an initial connection. This avoids the "proxy: error reading status line from remote server" error message caused by the race condition that the backend server closed the pooled connection after the connection check by the proxy and before data sent by the proxy reached the backend. It has to be kept in mind that setting this variable downgrades performance, especially with HTTP/1.0 clients. I am really concerned about this downgrade in performance therefore I started to look at nginx immediately. I am new to nginx and time is crucial right now, I can't afford to waste days to study it just to find out there is the same race condition issue. Is nginx affected by this connection pool race condition? Thanks

Passwordless SSH not working - keys copied and permissions set

- by Comcar

I know this question has been asked, but I'm certain I've done what all the other answers suggest. Machine A: used keygen -t rsa to create id_rsa.pub in ~/.ssh/ copied Machine A's id_rsa.pub to Machine B user's home directory Made the file permissions of id_rsa.pub 600 Machine B added Machine A's pub key to authorised_keys and authorised_keys2: cat ~/id_rsa.pub ~/.ssh/authorised_keys2 made the file permissions of id_rsa.pub 600 I've also ensured both the .ssh directories have the permission 700 on both machine A and B. If I try to login to machine B from machine A, I get asked for the password, not the ssh pass phrase. I've got the root users on both machines to talk to each other using password-less ssh, but I can't get a normal user to do it. Do the user names have to be the same on both sides? Or is there some setting else where I've missed. Machine A is a Ubuntu 10.04 virtual machine running inside VirtualBox on a Windows 7 PC, Machine B is a dedicated Ubuntu 9.10 server UPDATE : I've run ssh with the option -vvv, which provides many many lines of output, but this is the last few commands: debug3: check_host_in_hostfile: filename /home/pete/.ssh/known_hosts debug3: check_host_in_hostfile: match line 1 debug1: Host '192.168.1.19' is known and matches the RSA host key. debug1: Found key in /home/pete/.ssh/known_hosts:1 debug2: bits set: 504/1024 debug1: ssh_rsa_verify: signature correct debug2: kex_derive_keys debug2: set_newkeys: mode 1 debug1: SSH2_MSG_NEWKEYS sent debug1: expecting SSH2_MSG_NEWKEYS debug3: Wrote 16 bytes for a total of 1015 debug2: set_newkeys: mode 0 debug1: SSH2_MSG_NEWKEYS received debug1: SSH2_MSG_SERVICE_REQUEST sent debug3: Wrote 48 bytes for a total of 1063 debug2: service_accept: ssh-userauth debug1: SSH2_MSG_SERVICE_ACCEPT received debug2: key: /home/pete/.ssh/identity ((nil)) debug2: key: /home/pete/.ssh/id_rsa (0x7ffe1baab9d0) debug2: key: /home/pete/.ssh/id_dsa ((nil)) debug3: Wrote 64 bytes for a total of 1127 debug1: Authentications that can continue: publickey,password debug3: start over, passed a different list publickey,password debug3: preferred gssapi-keyex,gssapi-with-mic,gssapi,publickey,keyboard-interactive,password debug3: authmethod_lookup publickey debug3: remaining preferred: keyboard-interactive,password debug3: authmethod_is_enabled publickey debug1: Next authentication method: publickey debug1: Trying private key: /home/pete/.ssh/identity debug3: no such identity: /home/pete/.ssh/identity debug1: Offering public key: /home/pete/.ssh/id_rsa debug3: send_pubkey_test debug2: we sent a publickey packet, wait for reply debug3: Wrote 368 bytes for a total of 1495 debug1: Authentications that can continue: publickey,password debug1: Trying private key: /home/pete/.ssh/id_dsa debug3: no such identity: /home/pete/.ssh/id_dsa debug2: we did not send a packet, disable method debug3: authmethod_lookup password debug3: remaining preferred: ,password debug3: authmethod_is_enabled password debug1: Next authentication method: password

nginx server over https using up all available file handles

- by mmr

Hi all, So I have an nginx server that's working over https with Sinatra. When I try to download a jnlp file in a configuration that works fine over Mongrel and http (no s), the nginx server fails to serve the file with a 504 error. Subsequent checking of the logs states that this error is due to overflowing the available number of file handles, ie, "24: too many open files". Running sudo lsof -p <nginx worker pid> gets me a huge list of files, all looking like: nginx 1771 nobody 11u IPv4 10867997 0t0 TCP localhost:44704->localhost:https (ESTABLISHED) nginx 1771 nobody 12u IPv4 10868113 0t0 TCP localhost:https->localhost:44704 (ESTABLISHED) nginx 1771 nobody 13u IPv4 10868114 0t0 TCP localhost:44705->localhost:https (ESTABLISHED) nginx 1771 nobody 14u IPv4 10868191 0t0 TCP localhost:https->localhost:44705 (ESTABLISHED) nginx 1771 nobody 15u IPv4 10868192 0t0 TCP localhost:44706->localhost:https (ESTABLISHED) nginx 1771 nobody 16u IPv4 10868255 0t0 TCP localhost:https->localhost:44706 (ESTABLISHED) nginx 1771 nobody 17u IPv4 10868256 0t0 TCP localhost:44707->localhost:https (ESTABLISHED) nginx 1771 nobody 18u IPv4 10868330 0t0 TCP localhost:https->localhost:44707 (ESTABLISHED) nginx 1771 nobody 19u IPv4 10868331 0t0 TCP localhost:44708->localhost:https (ESTABLISHED) nginx 1771 nobody 20u IPv4 10868434 0t0 TCP localhost:https->localhost:44708 (ESTABLISHED) Increasing the number of files that can be opened is no help, because then nginx just blows right past that limit. And no wonder, it looks like it's in some kind of loop to pull all available files. Any idea what's going on, and how to fix it?

HTTP responses curl and wget different results

- by Fab

To check HTTP response header for a set of urls I send with curl the following request headers foreach ( $urls as $url ) { // Setup headers - I used the same headers from Firefox version 2.0.0.6 $header[ ] = "Accept: text/xml,application/xml,application/xhtml+xml,"; $header[ ] = "text/html;q=0.9,text/plain;q=0.8,image/png,*/*;q=0.5"; $header[ ] = "Cache-Control: max-age=0"; $header[ ] = "Connection: keep-alive"; $header[ ] = "Keep-Alive: 300"; $header[ ] = "Accept-Charset: ISO-8859-1,utf-8;q=0.7,*;q=0.7"; $header[ ] = "Accept-Language: en-us,en;q=0.5"; $header[ ] = "Pragma: "; // browsers keep this blank. curl_setopt( $ch, CURLOPT_URL, $url ); curl_setopt( $ch, CURLOPT_USERAGENT, 'Googlebot/2.1 (+http://www.google.com/bot.html)'); curl_setopt( $ch, CURLOPT_HTTPHEADER, $header); curl_setopt( $ch, CURLOPT_REFERER, 'http://www.google.com'); curl_setopt( $ch, CURLOPT_HEADER, true ); curl_setopt( $ch, CURLOPT_NOBODY, true ); curl_setopt( $ch, CURLOPT_RETURNTRANSFER, true ); curl_setopt( $ch, CURLOPT_FOLLOWLOCATION, true ); curl_setopt( $ch, CURLOPT_HTTPAUTH, CURLAUTH_ANY ); curl_setopt( $ch, CURLOPT_TIMEOUT, 10 ); //timeout 10 seconds } Sometimes I receive 200 OK which is good other time 301, 302, 307 which I consider good as well, but other times I receive weird status as 406, 500, 504 which should identify an invalid url but when I open it on the browser they are fine for example the script returns http://www.awe.co.uk/ => HTTP/1.1 406 Not Acceptable and wget returns wget http://www.awe.co.uk/ --2011-06-23 15:26:26-- http://www.awe.co.uk/ Resolving www.awe.co.uk... 77.73.123.140 Connecting to www.awe.co.uk|77.73.123.140|:80... connected.

Password Protect XML-RPC

- by Terence Eden

I have a service running on a server which I want to access via XML-RPC. I've installed all the necessary bits. Within /etc/apache2/httpd.conf I have the single line SCGIMount /RPC2 127.0.0.1:5000 I can run xmlrpc commands from my server - and any server which connects to /RPC2. What I want to do is password protect the directory to stop unauthorised usage. Within /etc/apache2/httpd.conf I've added <Location /RPC2> AuthName "Private" AuthType Basic AuthBasicProvider file AuthUserFile /home/me/myhtpasswd Require user me </Location> Trying to access /RPC2 brings up the "Authorization Required" box and it accepts my username and password. However, xmlrpc now doesn't work! If I run xmlrpc localhost some_command on my server, I get the error Failed. Call failed. HTTP response code is 401, not 200. (XML-RPC fault code -504) Is there any way I can password protect my /RPC2 directory and have xmlrpc commands work?

nginx error page and internal directives not working as expected

- by Romain

I'd like to setup my nginx server to return a specific error page on HTTP 50x status codes, and I'd like this page to be unavailable by a direct request from users (e.g., http//mysite/internalerror). For that, I'm using nginx's internal directive, but I must be missing something, as when I put that directive on my /internalerror location, nginx returns a custom 404 error (which isn't even my own 404 error page) when a page crashes. So, to summarize, here's what seems to happen: GET /Home nginx passes the query to Python I'm simulating an application bug to get the 502 error code nginx tries to return /InternalError from its error_page rule because of the internal rule, it finally fails back to a custom 404 error code <-- why? the documentation says error_page directives are not concerned by internal: http://wiki.nginx.org/HttpCoreModule#internal Here's an extract from nginx.conf with a few comments to point things out: error_page 404 /NotFound; error_page 500 502 503 504 =500 /InternalError; # HTTP 500 Error page declaration location / { try_files /Maintenance.html $uri @pythonbackend; } location @pythonbackend { include uwsgi_params; uwsgi_pass unix:///tmp/uwsgi.sock; } location ~* \.(py|pyc)$ { # This internal location works OK and returns my own 404 error page internal; } location /__Maintenance.html { # This one also works fine internal; } location ~* /internalerror { # This one doesn't work and returns nginx's 404 error page when I trigger an error somewhere on my site internal; } Thanks very much for your help!!

Facing application redirection issue on nginx+tomcat

- by Sunny Thakur

I am facing a strange issue on application which is deployed on tomcat and nginx is using in front of tomcat to access the application from browser. The issue is, i deployed the application on tomcat and now setup the virtual host on nginx under conf.d directory [File i created is virtual.conf] and below is the content i am using for the same. server { listen 81; server_name domain.com; error_log /var/log/nginx/domain-admin-error.log; location / { proxy_pass http://localhost:100; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_set_header Host $http_host; } error_page 500 502 503 504 /50x.html; location = /50x.html { root html; } Now the issue is this when i am using rewrite ^(.*) http://$server_name$1 permanent; in server section and access the URL then this redirects to https://domain.com and i am able to log in to app and able to access the links also [I am not using ssl redirection in this host file and i don't know why this is happening] Now when i removed this from server section then i am able to access the application from :81 and able to logged into the application but when i click on any link in app this redirect me to the login page. I am not getting any logs in application logs as well as tomcat logs. Please help on this if this is a redirection issue of nginx. Thanks, Sunny

I don't know if it's relevant :)

Disconnect from PHP after output generated

- by Oli

I have a LEMP stack. Nginx sitting in front of PHP-FPM. Because some of the sites are heavy and there's OPCode caching, PHP is set up so that there are only 5 child processes running. The aim being that each child can deal with any request in less than half-a-second and then move onto the next request. One problem I've found is that if it's a big chunk of HTML that's getting sent out, and the user has a slow connection, that PHP thread stays occupied until they've finished downloading. Because of my current setup, I have a pretty unforgiving timeout inside PHP where the script is killed after 20 seconds. This is to make sure everybody gets a turn but on a slow connection, this can mean the user gets cut off with a 504 Gateway timeout. I was wondering if there was some sort of buffer solution that I could implement within or just behind Nginx that sent the request through and then... well... buffered the content into its own cache and feed that onto the client as and when they could download it. The aim being that the underlying PHP thread can be freed up. What I'm asking for doesn't have to be PHP-specific. Anything that deals with FastCGI, or even any Nginx-upstream might have a similar issue to this.

Forward real IP through Haproxy => Nginx => Unicorn

Nginx and Gunicorn hanging on GET requests

nginx reverse proxy to apache mod_wsgi doesn't work

I'd appreciate any advice to point me in the right direction. I've tried several tutorials online to no avail.

How to test nginx proxy timeouts

- by mkorszun

Target: I would like to test all Nginx proxy timeout parameters in very simple scenario. My first approach was to create really simple HTTP server and put some timeouts: Between listen and accept to test proxy_connect_timeout Between accept and read to test proxy_send_timeout Between read and send to test proxy_read_timeout Test: 1) Server code (python): import socket import os import time import threading def http_resp(conn): conn.send("HTTP/1.1 200 OK\r\n") conn.send("Content-Length: 0\r\n") conn.send("Content-Type: text/xml\r\n\r\n\r\n") def do(conn, addr): print 'Connected by', addr print 'Sleeping before reading data...' time.sleep(0) # Set to test proxy_send_timeout data = conn.recv(1024) print 'Sleeping before sending data...' time.sleep(0) # Set to test proxy_read_timeout http_resp(conn) print 'End of data stream, closing connection' conn.close() def main(): s = socket.socket(socket.AF_INET, socket.SOCK_STREAM) s.setsockopt(socket.SOL_SOCKET, socket.SO_REUSEADDR, 1) s.bind(('', int(os.environ['PORT']))) s.listen(1) print 'Sleeping before accept...' time.sleep(130) # Set to test proxy_connect_timeout while 1: conn, addr = s.accept() t = threading.Thread(target=do, args=(conn, addr)) t.start() if __name__ == "__main__": main() 2) Nginx configuration: I have extended Nginx default configuration by setting explicitly proxy_connect_timeout and adding proxy_pass pointing to my local HTTP server: location / { proxy_pass http://localhost:8888; proxy_connect_timeout 200; } 3) Observation: proxy_connect_timeout - Even though setting it to 200s and sleeping only 130s between listen and accept Nginx returns 504 after ~60s which might be because of the default proxy_read_timeout value. I do not understand how proxy_read_timeout could affect connection at so early stage (before accept). I would expect 200 here. Please explain! proxy_send_timeout - I am not sure if my approach to test proxy_send_timeout is correct - i think i still do not understand this parameter correctly. After all, delay between accept and read does not force proxy_send_timeout. proxy_read_timeout - it seems to be pretty straightforward. Setting delay between read and write does the job. So I guess my assumptions are wrong and probably I do not understand proxy_connect and proxy_send timeouts properly. Can some explain them to me using above test if possible (or modifying if required).

Trouble with nginx and serving from multiple directories under the same domain

I have nginx setup to serve from /usr/share/nginx/html, and it does this fine. I also want to add it to serve from /home/user/public_html/map on the same domain. So: my.domain.com would get you the files in /usr/share/nginx/html my.domain.com/map would get you the files in /home/user/public_html/map With the below configuration (/etc/nginx/nginx.conf) it appears to be going to my.domain.com/map/map as noticed by this: 2011/03/12 09:50:26 [error] 2626#0: *254 "/home/user/public_html/map/map/index.html" is forbidden (13: Permission denied), client: <edited ip address>, server: _, request: "GET /map/ HTTP/1.1", host: "<edited>" I've tried a few things but I'm still not able to get it to cooperate, so any help would be greatly appreciated. ####################################################################### # # This is the main Nginx configuration file. # ####################################################################### #---------------------------------------------------------------------- # Main Module - directives that cover basic functionality #---------------------------------------------------------------------- user nginx; worker_processes 1; error_log /var/log/nginx/error.log; pid /var/run/nginx.pid; #---------------------------------------------------------------------- # Events Module #---------------------------------------------------------------------- events { worker_connections 1024; } #---------------------------------------------------------------------- # HTTP Core Module #---------------------------------------------------------------------- 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; keepalive_timeout 65; server { listen 80; server_name _; #access_log logs/host.access.log main; location / { root /usr/share/nginx/html; index index.html index.htm; } location /map { root /home/user/public_html/map; index index.html index.htm; } error_page 404 /404.html; location = /404.html { root /usr/share/nginx/html; } error_page 500 502 503 504 /50x.html; location = /50x.html { root /usr/share/nginx/html; } } include /etc/nginx/conf.d/*.conf; }

Nginx redirect all request that does not match a file to a php file

- by cyrbil

I'm trying to get all request to: http://mydomain.com/downloads/* redirect to http://mydomain.com/downloads/index.php except if the requested file exist in /downloads/ ex: http://mydomain.com/downloads = /downloads/index.php http://mydomain.com/downloads/unknowfile = /downloads/index.php http://mydomain.com/downloads/existingfile = /downloads/existingfile My current problem is I have either the redirection to php working but static files not served or the opposite. Here is my current vhost conf: (which redirect fine but static files are send to php and fail) server { listen 80; ## listen for ipv4; this line is default and implied server_name domain.com; root /data/www; index index.php index.html; location / { try_files $uri $uri/ /index.html; } error_page 404 /404.html; # redirect server error pages to the static page /50x.html error_page 500 502 503 504 /50x.html; location = /50x.html { root /usr/share/nginx/www; } location ^~ /downloads { fastcgi_pass unix:/var/run/php5-fpm.sock; fastcgi_split_path_info ^(.+\.php)(/.+)$; fastcgi_index index.php; include fastcgi_params; try_files $uri @downloads; } location @downloads { rewrite ^ /downloads/index.php; } # pass the PHP scripts to FastCGI server # location ~ \.php$ { try_files $uri =404; fastcgi_split_path_info ^(.+\.php)(/.+)$; fastcgi_pass unix:/var/run/php5-fpm.sock; fastcgi_index index.php; include fastcgi_params; } } Precision: static files are symlinks created by /downloads/index.php Thank you for your help.

Nginx and 1000 WordPress Installs - Optimization

- by GTE

Hey, I'm trying to create a rather unusual (imo) configuration where I have: nginx php-fastcgi mysql 1000 seperate WordPress installs (with WP Super Cache). Each WP install corresponds to a seperate subdomain. Furthermore, I have 1000 cron jobs being called every hour that in turn call a WP plugin (using wget) which retrieves data from an API and posts it to the respective blog. This is all being run on a virtual server with 1024MB of RAM, 4 shared processors, etc. The server is not doing well, especially during the times that the cron jobs are being executed. Nginx constantly throws 504 errors and the site has a significant lag. 1) Am I crazy for having 1000 individual WP installs? Should I be using WP-MU and will this help significantly? (I have certain plugin restrictions that I prefer having seperate installs but could switch if need be.) 2) Instead of having 1000 unique cron jobs - should be calling say a bash script that will then process the 1000 HTTP requests I need? Could this be done in a succesive order instead of a sequential one? 3) Any other kind of suggestion you may have for optimization? Should I be proxying to Apache instead of just using nginx, etc. Any kind of advice would be appreciated. Thanks in advance

SPARC T5-4 LDoms for RAC and WebLogic Clusters

- by Jeff Taylor-Oracle

I wanted to use two Oracle SPARC T5-4 servers to simultaneously host both Oracle RAC and a WebLogic Server Cluster. I chose to use Oracle VM Server for SPARC to create a cluster like this: There are plenty of trade offs and decisions that need to be made, for example: Rather than configuring the system by hand, you might want to use an Oracle SuperCluster T5-8 My configuration is similar to jsavit's: Availability Best Practices - Example configuring a T5-8 but I chose to ignore some of the advice. Maybe I should have included an alternate service domain, but I decided that I already had enough redundancy Both Oracle SPARC T5-4 servers were to be configured like this: Cntl 0.25 4 64GB App LDom 2.75 CPU's 44 cores 704 GB DB LDom One CPU 16 cores 256 GB The systems started with everything in the primary domain: #

Nginx as a proxy to Tomcat

- by Langali

Pardon me, this is my first attempt at Nginx-Jetty instead of Apache-JK-Tomcat. I deployed myapp.war file to $JETTY_HOME/webapps/, and the app is accessible at the url: http://myIP:8080/myapp I did a default installation of Nginx, and the default Nginx page is accessible at http://myIP Then, I modified the default domain under /etc/nginx/sites-enabled to the following: server { listen 80; server_name mydomain.com; access_log /var/log/nginx/localhost.access.log; location / { #root /var/www/nginx-default; #index index.html index.htm; proxy_pass http://127.0.0.1:8080/myapp/; } error_page 500 502 503 504 /50x.html; location = /50x.html { root /var/www/nginx-default; } } Now I get the index page of mypp (running in jetty) when I hit myIP, which is good. But all the links are malformed. eg. The link to css is mydomain.com/myapp/css/style.css while what it should have been is mydomain.com/css/style.css. It seems to be mapping http://mydomain.com to http://127.0.0.1:8080 instead of http://127.0.0.1:8080/myapp/ Any idea what am missing? Do I need to change anything on the Jetty side too?

java.lang.NoSuchMethodException: javax.ejb.EJBHome.getHomeHandle()

I'm trying to figure out why I'm getting the following exception when a client app is connecting to JBoss.

Passenger, Nginx, and Capistrano - Passenger not launching Rails app at all

- by Throlkim

Essentially, my route is working perfectly, Passenger seems to be loading - all is hunky-dory. Except that nothing Railsy happens. Here's my Nginx log from starting the server to the first request (ignore the different domain/route - it's because I haven't moved the new domain over yet, and it's returning a 403 error because there's no index file in the public folder): [ pid=24559 file=ext/nginx/HelperServer.cpp:826 time=2009-11-10 00:49:13.227 ]: Passenger helper server started on PID 24559 [ pid=24559 file=ext/nginx/HelperServer.cpp:831 time=2009-11-10 00:49:13.227 ]: Password received. 2009/11/10 00:49:53 [error] 24578#0: *1 directory index of "/var/www/***/current/public/" is forbidden, client: 188.221.195.27, server: ***, request: "GET / HTTP/1.1", host: "***" 2009/11/10 00:49:54 [error] 24578#0: *1 open() "/var/www/***/current/public/favicon.ico" failed (2: No such file or directory), client: 188.221.195.27, server: ***, request: "GET /favicon.ico HTTP/1.1", host: "***", referrer: "***" Someone on the RubyOnRails IRC channel suggested that it might be a webserver permissions problem. I had a suspicion that it might be a filesystem permission problem, but then Nginx runs as www-data and Passenger as root. I can load static files from within the public directory fine, but no Rails application is being launched. Does anyone have an idea? My head is gradually melting away figuring this one out! Edit: Here's the vhost file: server { listen 80; server_name ***; passenger_enabled on; location / { root /var/www/***/current/public; index index.html index.htm; } #error_page 404 /404.html; # redirect server error pages to the static page /50x.html # error_page 500 502 503 504 /50x.html; location = /50x.html { root html; } }
