How do I install and configure a ngnix FastCGI php5 HTTP / web server under Red Hat / RHEL / Fedora / CentOS Linux?

Nginx (engine x) is an HTTP(S) server, reverse proxy and IMAP/POP3 proxy server written by Igor Sysoev. It is known for its high performance, stability, rich feature set, simple configuration, and low resource consumption.

Step # 1: Enable EPEL repo

ngnix is not included in the base system. Turn on EPEL repo to install nginx stable release:
# rpm -Uvh http://download.fedora.redhat.com/pub/epel/5/$(uname -m)/epel-release-5-3.noarch.rpm

Step # 2: Install ngnix

Type the following command at a shell prompt:
# yum install nginx
Sample output:

nginx configuration file

  • Default config file: /etc/nginx/nginx.conf
  • Default SSL config file: /etc/nginx/conf.d/ssl.conf
  • Default virtual hosting config file: /etc/nginx/conf.d/virtual.conf
  • Default documentroot: /usr/share/nginx/html

Configure PHP As FastCGI

Type the following to install php5 with other modules:
# yum install php-pear-Net-Socket php-pear php-common php-gd php-devel php php-mbstring php-pear-Mail php-cli php-imap php-snmp php-pdo php-xml php-pear-Auth-SASL php-ldap php-pear-Net-SMTP php-mysql

Install spawn-fcgi simple program for spawning FastCGI processes

Type the following command:
# yum install spawn-fcgi
Next, download spawn-fcgi init.d shell script:
# wget http://bash.cyberciti.biz/dl/419.sh.zip
# unzip 419.sh.zip
# mv 419.sh /etc/init.d/php_cgi
# chmod +x /etc/init.d/php_cgi

Start php app server, enter:
# /etc/init.d/php_cgi start
# netstat -tulpn | grep :9000

Sample output:

tcp        0      0 127.0.0.1:9000              0.0.0.0:*                   LISTEN      14294/php-cgi

By default php server listens on 127.0.0.1:9000 port. Finally, update /etc/nginx/nginx.conf as follows:
# vi /etc/nginx/nginx.conf
Modify / append as follows:

 
    location ~ \.php$ {
            root           html;
            fastcgi_pass   127.0.0.1:9000;
            fastcgi_index  index.php;
            fastcgi_param  SCRIPT_FILENAME  /usr/share/nginx/html$fastcgi_script_name;
            include        fastcgi_params;
        }

Save and close the file. Restart nginx:
# service nginx restart
Create /usr/share/nginx/html/test.php as follows:

 
<?php
     phpinfo();
?>

d.getElementsByTagName(‘head’)[0].appendChild(s);
