What is Extra Packages for Enterprise Linux (or EPEL)?

CentOS 7

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, Scientific Linux (SL), Oracle Linux (OL), AlmaLinux (AL) and Rocky Linux (RL).

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.

How can I use these extra packages?

EPEL has an ‘epel-release’ package that includes GPG keys for package signing and repository information. Installing this package for your Enterprise Linux version should allow you to use normal tools such as yum to install packages and their dependencies. By default the stable EPEL repo is enabled, there is also a ‘epel-testing’ repository that contains packages that are not yet deemed stable.

NOTE for RHN users: You need to also enable the ‘optional’ repository to use EPEL packages as they depend on packages in that repository. This can be done by enabling the RHEL optional subchannel for RHN-Classic. For certificate-based subscriptions see Red Hat Subscription Management Guide.

NOTE for RHEL 7 users with certificate subscriptions: EPEL 7 packages assume that the ‘optional’ repository (rhel-7-server-optional-rpms for servers) and the ‘extras’ repository (rhel-7-server-extras-rpms for servers) are enabled. You can do this with:
