Search Package from EPEL Repo

Let’s assume if we want to search Zabbix package in epel repository, execute the following dnf command,

[[email protected] ~]# dnf repository-packages epel list | grep -i zabbix

Output of above command would be something like below,

epel-repo-search-package-centos8

Install a package from epel repo

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>

[[email protected] ~]# 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.
