At the previous post, i have setup Nginx as reverse proxy to apache web server. This post will covers the steps how to setup nginx web server to use PHP-FastCGI for dynamic content. Nginx (pronounced “Engine-X”) is a free, open-source HTTP Web server and one of the alternative to Apache http server. It’s a high performance edge web server with the lowest memory footprint and the key features to build modern and efficient web infrastructure. FastCGI is a language independent, scalable, open extension to CGI that provides high performance without the limitations of server specific APIs. FastCGI provides better scalability and performance.
1. Prepared yum repository for nginx :
[root@centos63 ~]# vi /etc/yum.repos.d/nginx.repo
[nginx]
name=nginx repo
baseurl=http://nginx.org/packages/centos/$releasever/$basearch/
gpgcheck=0
enabled=1
2. Install Nginx :
[root@centos63 ~]# yum install nginx -y
3. Install required php packages :
[root@centos63 ~]# yum install php-cli php-mysql php-gd php-imap php-ldap php-odbc php-pear php-xml php-xmlrpc php-eaccelerator php-magickwand php-magpierss php-mbstring php-mcrypt php-mssql php-shout php-snmp php-soap php-tidy -y

4. Configure EPEL Repository on CentOS 6.3 and install spawn-fcgi :
[root@centos63 ~]# yum install spawn-fcgi -y
5. Start configure nginx. It is better to backup original nginx config file :
[root@centos63 ~]# cp /etc/nginx/nginx.conf /etc/nginx/nginx.conf.bak
6. Create nginx DocumentRoot for ehowstuff.local virtual host :
[root@centos63 ~]# mkdir -p /var/www/html/ehowstuff.local
[root@centos63 ~]# mkdir -p /var/www/html/ehowstuff.local/public_html
[root@centos63 ~]# chown -R nginx:nginx /var/www/html/ehowstuff.local/public_html
7. Create folder where to store access.log and error.log :
[root@centos63 ~]# mkdir -p /var/log/nginx/ehowstuff.local
[root@centos63 ~]# chown -R nginx:nginx /var/log/nginx/ehowstuff.local
8. Modify default nginx config file :
[root@centos63 ~]# vi /etc/nginx/nginx.conf
user nginx;
worker_processes 1;
error_log /var/log/nginx/error.log warn;
pid /var/run/nginx.pid;
events {
worker_connections 1024;
}
http {
include /etc/nginx/mime.types;
default_type application/octet-stream;
log_format main '$remote_addr - $remote_user [$time_local] "$request" '
'$status $body_bytes_sent "$http_referer" '
'"$http_user_agent" "$http_x_forwarded_for"';
access_log /var/log/nginx/access.log main;
sendfile on;
#tcp_nopush on;
keepalive_timeout 65;
#gzip on;
include /etc/nginx/conf.d/*.conf;
}
9. Add the host configuration file under /etc/nginx/conf.d/. Nginx config file will load all *.conf files under conf.d folder.
As example, the website domain is ehowstuff.local. So virtual server ehowstuff.local will be created and named as ehowstuff.local.conf :
[root@centos63 ~]# vi /etc/nginx/conf.d/ehowstuff.local.conf
server {
server_name www.ehowstuff.local ehowstuff.local;
access_log /var/log/nginx/ehowstuff.local/access.log;
error_log /var/log/nginx/ehowstuff.local/error.log;
root /var/www/html/ehowstuff.local/public_html;
location / {
index index.html index.htm index.php;
}
location ~ \.php$ {
include /etc/nginx/fastcgi_params;
fastcgi_pass 127.0.0.1:9000;
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME /var/www/html/ehowstuff.local/public_html$fastcgi_script_name;
}
}
10. Check your nginx version :
[root@centos63 ~]# nginx -v
nginx version: nginx/1.2.4
11. Configure php-fastcgi :
[root@centos63 ~]# cd /opt
[root@centos63 opt]# wget -O php-fastcgi-rpm.sh http://library.linode.com/assets/696-php-fastcgi-rpm.sh
[root@centos63 opt]# mv php-fastcgi-rpm.sh /usr/bin/php-fastcgi
[root@centos63 opt]# chmod +x /usr/bin/php-fastcgi
[root@centos63 opt]# wget -O php-fastcgi-init-rpm.sh http://library.linode.com/assets/697-php-fastcgi-init-rpm.sh
[root@centos63 opt]# mv php-fastcgi-init-rpm.sh /etc/rc.d/init.d/php-fastcgi
[root@centos63 opt]# chmod +x /etc/rc.d/init.d/php-fastcgi
12. Start php-fastcgi to control spawn-fcgi :
[root@centos63 ~]# /etc/init.d/php-fastcgi start
Starting php-cgi: spawn-fcgi: child spawned successfully: PID: 3380
[ OK ]
13. Start Nginx service :
[root@centos63 ~]# service nginx start
14. Make Nginx and php-fastcgi start at boot :
[root@centos63 opt]# chkconfig --add nginx
[root@centos63 opt]# chkconfig nginx on
[root@centos63 opt]# chkconfig --add php-fastcgi
[root@centos63 opt]# chkconfig php-fastcgi on
