How to install nginx on centos

How can I install Nginx web server On CentOS Linux 6 or Red Hat? Nginx is faster at serving static files and consumes much less memory for concurrent requests because Nginx is event-based it doesn’t need to spawn new processes or threads for each request, so its memory usage is very low.

Add nginx yum repository

nano /etc/yum.repos.d/nginx.repo

add this to Centos

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

add this if to RHEL

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

Install nginx web-server

yum install nginx
