If you have a large WordPress setup or a server with limited resources, then you will often see the “504 Gateway Time-out” error.
You can follow the steps given below to increase the timeout value. PHP default is 30s.
Changes in php.ini
If you want to change max execution time limit for php scripts from 30 seconds (default) to 300 seconds.
vim /etc/php5/fpm/php.iniSet…
max_execution_time = 300In Apache, applications running PHP as a module above would have suffice. But in our case we need to make this change at 2 more places.
Changes in PHP-FPM
This is only needed if you have already un-commented request_terminate_timeout parameter before. It is commented by default, and takes value of max_execution_time found in php.ini
Edit…
vim /etc/php5/fpm/pool.d/www.confSet…
request_terminate_timeout = 300Changes in Nginx Config
To increase the time limit for example.com by
vim /etc/nginx/sites-available/example.comlocation ~ .php$ {
include /etc/nginx/fastcgi_params;
fastcgi_pass unix:/var/run/php5-fpm.sock;
fastcgi_read_timeout 300;
}If you want to increase time-limit for all-sites on your server, you can edit main nginx.conf file:
vim /etc/nginx/nginx.confAdd following in http{..} section
http {
#...
fastcgi_read_timeout 300;
#...
}Reload PHP-FPM & Nginx
Don’t forget to do this so that changes you have made will come into effect:
service php5-fpm reload
service nginx reload
