Install Nginx PHP-FPM on CentOS

Install Nginx PHP-FPM on CentOS

NGINX (pronounced engine-x) is an open source web server that excels at large scale web integration, application security, web acceleration, content and application delivery and  PHP-FPM (FastCGI Process Manager) is an alternative PHP FastCGI implementation with some additional features useful especially for heavy traffic sites.

Below are the steps to install Nginx + PHP-FPM  on CentOS 6 Server.

First of all you will have to add the remi repository and install php-fpm with php modules.

rpm -Uvh http://rpms.famillecollet.com/enterprise/remi-release-6.rpm
yum --enablerepo=remi install php php-common php-cli php-fpm php-mysql php-pdo php-pecl-apc php-mcrypt php-xml php-gd php-mbstring

The add the nginx repo and install nginx.   Create file /etc/yum.repos.d/nginx.repo and add the below contents to it

[nginx]
name=nginx repo
baseurl=http://nginx.org/packages/centos/$releasever/$basearch/
gpgcheck=0
enabled=1

Now install the nginx

yum -y install nginx

Now it’s time to do the configuration. PHP-FPM daemon process by default listens on port 9000 and the default user is apache. We can configure it to listen on unix socket and run as user nginx. Edit the file /etc/php-fpm.d/www.conf and make the below changes

#listen = 127.0.0.1:9000
listen = /var/run/php-fpm/php-fpm.sock

# change user to nginx instead of apache
#user = apache
user = nginx
#group = apache
group = nginx

Now edit the nginx configuration file /etc/nginx/conf.d/default.conf and make the below changes.( Add the lines if they don’t exist)

location ~ \.php$ {
      #include /etc/nginx/fastcgi.conf;
      fastcgi_split_path_info  ^(.+\.php)(.*)$;
      #fastcgi_pass   127.0.0.1:9000;
      fastcgi_pass unix:/var/run/php-fpm/php-fpm.sock;
      fastcgi_index  index.php;
      fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
      #fastcgi_param  SCRIPT_FILENAME  $request_filename;
      include fastcgi_params;
}
