How to Enable EPEL Repository on CentOS 8 and RHEL 8 Server
======
**EPEL** Stands for Extra Packages for Enterprise Linux, it is a free and opensource additional packages repository available for **CentOS** and **RHEL** servers. As the name suggests, EPEL repository provides extra and additional packages which are not available in the default package repositories of [CentOS 8][1] and [RHEL 8][2].
In this article we will demonstrate how to enable and use epel repository on CentOS 8 and RHEL 8 Server.

### Prerequisites of EPEL Repository
* Minimal CentOS 8 and RHEL 8 Server
* Root or sudo admin privileges
* Internet Connection
### Install and Enable EPEL Repository on RHEL 8.x Server
Login or ssh to your RHEL 8.x server and execute the following dnf command to install EPEL rpm package,
```
[root@linuxtechi ~]# dnf install https://dl.fedoraproject.org/pub/epel/epel-release-latest-8.noarch.rpm -y
```
Output of above command would be something like below,
![dnf-install-epel-repo-rehl8][3]
Once epel rpm package is installed successfully then it will automatically enable and configure its yum / dnf repository.  Run following dnf or yum command to verify whether EPEL repository is enabled or not,
```
[root@linuxtechi ~]# dnf repolist epel
Or
[root@linuxtechi ~]# dnf repolist epel -v
```
![epel-repolist-rhel8][3]
### Install and Enable EPEL Repository on CentOS 8.x Server
Login or ssh to your CentOS 8 server and execute following dnf or yum command to install **epel-release** rpm package. In CentOS 8 server, epel rpm package is available in its default package repository.
```
[root@linuxtechi ~]# dnf install epel-release -y
Or
[root@linuxtechi ~]# yum install epel-release -y
```
Execute the following commands to verify the status of epel repository on CentOS 8 server,
```

### Search a package from epel repository
Lets assume if we want to search Zabbix package in epel repository, execute the following dnf command,
```
[root@linuxtechi ~]# dnf repository-packages epel list | grep -i zabbix
```
Output of above command would be something like below,
![epel-repo-search-package-centos8][3]
### Install a package from epel repository
Lets assume we want to install htop package from epel repo, then issue the following dnf command,
Syntax:
# dnf enablerepo=”epel” install <pkg_name>
```
[root@linuxtechi ~]# dnf --enablerepo="epel" install htop -y
```
**Note:** If we dont specify the “**enablerepo=epel**” in above command then it will look for htop package in all available package repositories.
Thats all from this article, I hope above steps helps you to enable and configure EPEL repository on CentOS 8 and RHEL 8 Server, please dont hesitate to share your comments and feedback in below comments section.
