Nginx + php-fpm "504 Gateway Time-out" error with almost zero load (on a test-server)

Solution 1:

I found answer on my posting on the nginx forum - http://forum.nginx.org/read.php?2,127854

The answer, in my case, is to set:

request_terminate_timeout=30s

in php-fpm config (usually /etc/php5/fpm/php-fpm.conf)

Note, you can use values other than 30s also.

I used it to match my value in main php.ini file which is:

max_execution_time = 30

Thanks All. :-)

Solution 2:

Here how it resolved my issue:

make following changes to /etc/nginx/nginx.conf in http { section

proxy_connect_timeout  600s;
proxy_send_timeout  600s;
proxy_read_timeout  600s;
fastcgi_send_timeout 600s;
fastcgi_read_timeout 600s;

and then restart nginx

/etc/init.d/nginx restart

Solution 3:

If you are using php 5.3, increase the backlog.

If you are using php 5.2, backport the patch to increase the backlog size from 128.

Also, use a unix socket rather than a TCP socket. unix:/tmp/php5-cgi.sock (or the relevant path)

Solution 4:

Great, thanks

request_terminate_timeout=30s

It works perfectly for me

but, I had to insert the line in this file : "/etc/php5/fpm/pool.d/www.conf" that is to say in the "Worker Section".

PHP 5.3.21-1 - Wordpress 3.5.1

Solution 5:

in my case (same nginx error message), some problematic php scripts are not ending to execute and waiting for something, resulting no more php5-fpm children for nginx to pick.

fix:

1. add execution time limit other mentioned it this post. request_terminate_timeout=30s
2. raise children number. and everything worked like a charm. pm.max_spare_servers=16 pm.min_spare_servers=2

now everything worked like a charm.
