Introduction
The EPEL (Extra Packages for Enterprise Linux) repository contains additional software packages not available in the default Red Hat and CentOS repositories. EPEL was formed because Fedora developers wished to use the packages they maintain on Red Hat Enterprise Linux (RHEL) and its derivatives such as CentOS, Oracle Linux, and Scientific Linux.
You may access well-known software packages like Nginx, R, and Python Pip by enabling this repository.
Prerequisites
Make sure you are logged in as a user with sudo privileges before starting the lesson.
Enabling the EPEL Repository on CentOS 7
Since the EPEL rpm package is already present in the CentOS extras repository, enabling the EPEL repository on CentOS 7 is a simple task.
Please enter the following command to install the EPEL release package:
sudo yum install epel-release
Run the yum repolist command, which lists all accessible repositories, to make sure the EPEL repository is enabled.
sudo yum repolist
The repo ID, name, and the number of packages for the enabled repositories are displayed by the command. The EPEL repository should be listed in the output.

All done. The EPEL repository has been activated on your CentOS system.
Enabling the EPEL Repository on RHEL
The RHEL-based distributions including Red Hat, CentOS 6 and 7, Oracle Linux, Amazon Linux, and Scientific Linux are all compatible with this method.
Run the following command to download and install the EPEL release package and enable the EPEL repository:
sudo yum install https://dl.fedoraproject.org/pub/epel/epel-release-latest-$(rpm -E '%{rhel}').noarch.rpm
rpm -E '%{rhel}' will print the distribution version (6 or 7).Conclusion
