Learn how to install EPEL repository (Extra Packages for Enterprise Linux) in YUM based Linux. It enables you to install open source packages.
What is EPEL
EPEL stands for Extra Packages for Enterprise Linux. EPEL repository is helpful and rich with packages that are normally used/needed for commonly used Linux software. This repository is managed by the EPEL group. This repository contains all 100% free open source packages which may not available in the core
EPEL repos should be used in production with extra caution.
As you know EPEL group is the Fedora project, EPEL repository can be enabled for YUM based systems like RHEL, Oracle Linux, Fedora, CentOS, etc distributions.
How to configure EPEL
Adding EPEL repository can take a different route than adding https, FTP repositories in YUM. For EPFL, you need to download related RPM from link using any Linux downloaders. Choose correct distro and architecture while choosing a download link for the EPEL package. Or you can choose noarch rpm as I did below.
I downloaded rpm using wget as below :
# wget https://dl.fedoraproject.org/pub/epel/epel-release-latest-6.noarch.rpm

Thats it. EPEL repository is accommodated by your YUM configuration now.
EPEL repository test
Let’s test the EPEL repository if it’s configured properly. You should see below the new repo in directory /etc/yum.repos.d This is the first indication EPEL is configured.
# pwd
/etc/yum.repos.d
# ll
total 32
-rw-r--r--. 1 root root 957 Nov 4 2012 epel.repo
-rw-r--r--. 1 root root 1056 Nov 4 2012 epel-testing.repo
Now extract repolist from yum to verify configuration.
# yum repolist
Loaded plugins: amazon-id, rhui-lb, security
repo id repo name status
