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
|
||
```
|
||
|
||

|
||
|
||
### 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,
|
||
|
||
```

Above command’s output confirms that we have successfully enabled epel repo. Let’s perform some basic operations on EPEL repo.
|
||
|
||
### List all available packages from epel repository
|
||
|
||
If you want to list all the packages from epel repository then run the following dnf command,
|
||
|
||
```
|
||
[root@linuxtechi ~]# dnf repository-packages epel list

||
[root@linuxtechi ~]#

||
```
|
||
|
||
### Search a package from epel repository
|
||
|
||
Let’s 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
|
||
|
||
Let’s 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 don’t specify the “**–enablerepo=epel**” in above command then it will look for htop package in all available package repositories.
|
||
|
||
That’s all from this article, I hope above steps helps you to enable and configure EPEL repository on CentOS 8 and RHEL 8 Server, please don’t hesitate to share your comments and feedback in below comments section.
