Install EPEL repository¶

preliminary note¶

Extra Packages for Enterprise Linux (or EPEL) is a Fedora Special Interest Group that creates, maintains, and manages a high quality set of additional packages for Enterprise Linux, including, but not limited to, Red Hat Enterprise Linux (RHEL),CentOS and Scientific Linux (SL).

EPEL packages are usually based on their Fedora counterparts and will never conflict with or replace packages in the base Enterprise Linux distributions. EPEL uses much of the same infrastructure as Fedora, including buildsystem, bugzilla instance, updates manager, mirror manager and more.

as of CentOS7-1810 there is no need to download the .rpm anymore.
You may install the EPEL-repo directly via

yum install epel-release

Download EPEL release package¶

cd ~
wget http://dl.fedoraproject.org/pub/epel/7/x86_64/Packages/e/epel-release-7-11.noarch.rpm

Install Package¶

yum install epel-release-7-11.noarch.rpm

This will add a yum repository config file and import the appropriate GPG keys.
