For those of you who didn’t know, Nginx is one of the most popular web servers in the world and is responsible for hosting some of the largest and highest-traffic sites on the internet. It is more resource-friendly than Apache in most cases and can be used as a web server or a reverse proxy.
This article assumes you have at least basic knowledge of linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple. I will show you through the step by step installation nginx with fast-cgi on CentOS 6.
Step 1. To install, first you must add the EPEL yum repository information corresponding to your CentOS/RHEL version.
1 2 3 | ## RHEL/CentOS 6 32-Bit ## # wget http://download.fedoraproject.org/pub/epel/6/i386/epel-release-6-8.noarch.rpm # rpm -ivh epel-release-6-8.noarch.rpm |
1 2 3 | ## RHEL/CentOS 6 64-Bit ## # wget http://download.fedoraproject.org/pub/epel/6/x86_64/epel-release-6-8.noarch.rpm # rpm -ivh epel-release-6-8.noarch.rpm |
Step 2. Install Nginx package and dependencies.
1 2 | yumupdate yum-yinstallnginx |
Step 3. Install required php packages.

1 | chmod+x/etc/init.d/php-cgi |
Step 5. Configure Nginx web server.

Step 5. Start Nginx and PHP-FastCGI service.
1 2 | etc/init.d/nginxstart etc/init.d/php-cgistart |
Important: For security reasons, you’ll want to change/add the following line to /etc/php.ini and restart nginx:
1 | cgi.fix_pathinfo=0 |
Congratulation’s! You have successfully installed Nginx and PHP-FastCGI. Thanks for using this tutorial for installing Nginx and PHP-FastCGI on CentOS 6 systems.
