How to install EPEL 8 repository on CentOS 8 or Stream

RHEL 8 based CentOS latest operating system 8 is available to use now with BaseOS and APPstream as the default repository. However, there is a provision to install and enable the EPEL repository to add extra packages.

It has been a while the EPEL 8 repo (Extra Packages for Enterprise Linux) is available to install on Redhat 8, however, CentOS 8 is just released on 26 Sep 2019, thus, the method to install EPEP 8 on ti will be the same.

Now, what is the need for EPEL repo on CentOS or Redhat?

Actually there are so many packages or software that are not available to install using the official repository of RHEL, to compensate that lacking we can use this unofficial one. For example Sea monkey, AWStats, bionic client, byobu windows manager etc.

Furthermore, EPEL is a project of Fedora SIG, that has a responsibility to create and maintain additional packages for the enterprise Linux. It has more than 1,614 packages.

In this tutorial, we will see how to add EPEL 8 to RHEL 8 / CentOS 8/ Stream.

Open the command terminal

If you are using the CentOS 8 server with command-line interface then simply move to the next step. Those are on GUI go to Activites given on the left top side of the OS, click on that and select Terminal icon given on the left side menu bar.


Login as Root

To install EPEL 8 on CentOS 8, you must have the root access. To access root user type: su and then its password.


Check existing Repo

Let’s first check the existing repo which is officially available on our system, this will also give you an idea which repo has how many packages to install. For that type:

As we know RHEL 8 officially now support DNF package manager thus we can use that too:

dnf repolist

The total packages, while installing EPEL 8 on our testing were:

Install EPEL 8 on CentOS 8/Stream or RHEL 8

Finally, the command is here, just a single line and you are done. I hope you already have the root access. So either uses yum or dnf along with EPEL repo URL.

dnf install https://dl.fedoraproject.org/pub/epel/epel-release-latest-8.noarch.rpm

or

yum install https://dl.fedoraproject.org/pub/epel/epel-release-latest-8.noarch.rpm

As you run the command the system will validate the URL and ask for your permission to download the required package to enable the EPEL 8 repo.

Press Y and to give your permission.

Output:

[root@localhost ~]# dnf install https://dl.fedoraproject.org/pub/epel/epel-release-latest-8.noarch.rpm
