“504 Gateway Time-out” error
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.
If you want to change max execution time limit for php scripts from 30 seconds (default) to 300 seconds.
vim /etc/php5/fpm/php.ini
In 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.
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
vim /etc/php5/fpm/pool.d/www.conf
request_terminate_timeout = 300
To increase the time limit for example.com by
vim /etc/nginx/sites-available/example.com
location ~ \.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.conf
Add following in http.. section
http #... fastcgi_read_timeout 300; #...
Don’t forget to do this so that changes you have made will come into effect:
service php5-fpm reload service nginx reload Update: Sometimes it helps to disable the plugin for wordpress particular cache.
