How to configure EPEL repository on CentOS 8



The EPEL repository is an additional package repository that provides useful software packages that are not included in the official CentOS 8 repositories and easy access to install packages for commonly used software.
This article describes enabling EPEL on CentOS 8. It can be installed by below two methods.

Method 1. The package to enable EPEL repository is available in CentOS 8 repository and it can be installed by yum command.

Step 1. Package installation: Follow the below command to Install and Enable EPEL repository using yum:

[root@linuxcnf ~]# dnf install epel-release -y
……………..
Installed:
  epel-release-8-5.el8.noarch

Complete!
[root@linuxcnf ~]#

Step 2. Verification: Verify the installation using the below command:

[root@linuxcnf ~]# dnf repolist
………………………..
repo id                                                       repo name                                                                                           status
AppStream                                                     CentOS-8 - AppStream                                                                                4,928
BaseOS                                                        CentOS-8 - Base                                                                                     2,713
*epel                                                         Extra Packages for Enterprise Linux 8 - x86_64                                                      1,706
extras                                                        CentOS-8 - Extras                                                                                       3
[root@linuxcnf ~]#
