Configure Nginx and PHP-FPM to use sockets

The following guide describes how to configire Nginx and PHP-FPM to use Sockets on Centos 6. This guide assumes you have already installed a LEMP stack as shown in Install LEMP on Centos

Step 1 – Configure PHP-FPM

Edit the PHP-FPM configuration file and set the required values

vi /etc/php-fpm.d/www.conf

listen = /var/run/php-main.socket
listen.owner = nginx
listen.group = nginx
listen.mode = 0660

Alternatively the following sed commands will set the variables for you

sed -i s'/listen = 127.0.0.1:9000/listen = \/var\/run\/php-main.socket/' /etc/php-fpm.d/www.conf
sed -i s'/;listen.owner = nobody/listen.owner = nginx/' /etc/php-fpm.d/www.conf
sed -i s'/;listen.group = nobody/listen.group = nginx/' /etc/php-fpm.d/www.conf
sed -i s'/;listen.mode = 0660/listen.mode = 0660/' /etc/php-fpm.d/www.conf

Step 2 – Configure Nginx config

Edit the PHP-FPM configuration file and set the required values

vi /etc/nginx/conf.d/default.conf

fastcgi_pass unix:/var/run/php-main.socket;

Alternatively the following sed commands will set the variables for you

sed -i s'/fastcgi_pass   127.0.0.1:9000;/fastcgi_pass unix:\/var\/run\/php-main.socket;/' /etc/nginx/conf.d/default.conf

Step 3 – Restart the Services

All that’s left is to restart the services and test.

service php-fpm restart
service nginx restart
