How To Install and Enable EPEL Repository on Rocky Linux/Centos 8

In this guide, we will learn how to install and enable EPEL repository on Rocky Linux/Centos 8. This guide will also work for RHEL 8 and its derivatives like Alma Linux, Oracle Linux, Scientific Linux, etc.

EPEL is a repository that provides extra packages for Enterprise Linux. The EPEL repository is an additional package repository that provides easy access to install packages for commonly used software. This repo was created because Fedora contributors wanted to use Fedora packages they maintain on RHEL and other compatible distributions. The EPEL group creates, maintains and manages a high-quality set of additional packages. These packages may be software not included in the core repository, or sometimes updates which haven’t been provided yet.

# 3. Confirming EPEL installation

Use the following command to confirm epel repository:

$ sudo dnf repolist epel | grep epel
epel             Extra Packages for Enterprise Linux 8 - x86_64          enabled

List packages available on EPEL repository.

sudo dnf --disablerepo="*" --enablerepo="epel" list available

You can filter further to check if the required package is available on EPEL repository by piping the output to grep.

$ sudo dnf --disablerepo="*" --enablerepo="epel" list available | grep -i monit
gnome-monitor-config.x86_64                                       0-0.1.20190520.gitbc2f76c.el8                   epel

nordugrid-arc-monitor.noarch                                      6.13.0-1.el8                                    epel
perl-Monitoring-Plugin.noarch                                     0.40-1.el8                                      epel

To install package from EPEL repository, use the

--enablerepo="epel" argument to dnf install:

sudo dnf --enablerepo="epel" install <package>

Example

<meta charset="utf-8">sudo dnf --enablerepo="epel" install monit

The above command might install some dependencies from other repos like the Base repositories.

# Conclusion

In this guide we explored how to install and configure EPEL repo in RHEL 8 based systems like Rocky Linux. We saw that when installed, the installe automatically created a **.repo **file under /etc/yum.repos.d directory. You can disable the repository at any time by turning off the enabled flag.
