Add repo linux from EPEL

EPEL (Extra Packages for Enterprise Linux) is a volunteer-based community effort from the Fedora project to create a repository of high-quality add-on packages that complement the Fedora-based Red Hat Enterprise Linux (RHEL) and its compatible spinoffs, such as CentOS and Scientific Linux. As part of the Fedora packaging community, EPEL packages are 100% free/libre open source software (FLOSS).

I Use Centos 5.3 as my system operation. I Have a problem when I want to install fftw3 library. I try to get from rpmbone, but I get fftw3-3.1.1 version, but I want to install fftw3-3.2.2. I can compile source code, but I want more simple method with use yum command. When I try searching in internet, I can get new version of fftw3 from EPEL. This is a method how to add repo from EPEL to my system.

1. Open a terminal/konsole. login as root. Download fire repo from EPEL in here (this is for Redhat/Centos 5 32bit) or here (Redhat/Centos 5.3 64 bit) . You can get any version of EPEL for your Linux in here.
2. Install that file rpm with command : rpm -i epel-release-5-4.noarch.rpm.
3. Update your repo with command : yum update.
4. Check new software with command : yum search fftw3.

This is a simple method to add EPEL repo to your Redhat system operation. You can get more information about EPEL in this address :
