nginx

Nginx is a fast and lean http web server … its faster than apache.

http://nginx.org

1. Install from Source

Install required packages

yum install -y pcre pcre-devel

Install from source. By default nginx will install to /usr/local/nginx

Grab the latest version from http://nginx.org/en/download.html

cd /usr/local/src
ver=0.7.67
wget http://sysoev.ru/nginx/nginx-$ver.tar.gz
tar xzf nginx-$ver.tar.gz
cd nginx-$ver
./configure
make
sudo make install

2. Setup init.d script

vi /etc/init.d/nginx
#!/bin/sh
#
# nginx - this script starts and stops the nginx daemin
# Taken from http://www.hikaro.com
# chkconfig:   - 85 15 
# description:  Nginx is an HTTP(S) server, HTTP(S) reverse \
#               proxy and IMAP/POP3 proxy server
