What is EPEL

EPEL (Extra Packages for Enterprise Linux) is open source and free community based repository project from Fedora team which provides 100% high quality add-on software packages for Linux distribution including RHEL (Red Hat Enterprise Linux), CentOS, and Scientific Linux. Epel project is not a part of RHEL/Cent OS but it is designed for major Linux distributions by providing lots of open source packages like networking, sys admin, programming, monitoring and so on. Most of the epel packages are maintained by Fedora repo.

Why we use EPEL repository?

1. Provides lots of open source packages to install via Yum.
2. Epel repo is 100% open source and free to use.
3. It does not provide any core duplicate packages and no compatibility issues.
4. All epel packages are maintained by Fedora repo.

How To Enable EPEL Repository in RHEL/CentOS 7/6/5?

First, you need to download the file using Wget and then install it using RPM on your system to enable the EPEL repository. Use below links based on your Linux OS versions. (Make sure you must be root user).

Doing it with Systemd

You can also use Systemd to accomplish this. This is arguably the better method since you're managing the state of the system directly through Systemd and its CLIs.

You can see what your current default target is:
$ sudo systemctl get-default
multi-user.target

And then change it to graphical:
$ sudo systemctl set-default graphical.target

sudo yum install epel-release
