What is EPEL

EPEL (Extra Packages for Enterprise Linux) is open source and free community based repository project from Fedora team which provides 100% high quality add-on software packages for Linux distribution including RHEL (Red Hat Enterprise Linux), CentOS, and Scientific Linux. Epel project is not a part of RHEL/Cent OS but it is designed for major Linux distributions by providing lots of open source packages like networking, sys admin, programming, monitoring and so on. Most of the epel packages are maintained by Fedora repo.

Why we use EPEL repository?

  1. Provides lots of open source packages to install via Yum.
  2. Epel repo is 100% open source and free to use.
  3. It does not provide any core duplicate packages and no compatibility issues.
  4. All epel packages are maintained by Fedora repo.

How To Enable EPEL Repository in RHEL/CentOS 7/6/5?

First, you need to download the file using Wget and then install it using RPM on your system to enable the EPEL repository. Use below links based on your Linux OS versions. (Make sure you must be root user).

RHEL/CentOS 7 64 Bit

## RHEL/CentOS 7 64-Bit ##
# wget http://dl.fedoraproject.org/pub/epel/7/x86_64/e/epel-release-7-2.noarch.rpm

How Do I Verify EPEL Repo?

You need to run the following command to verify that the EPEL repository is enabled. Once you ran the command you will see epel repository.

# yum repolist

How Do I Use EPEL Repo?

You need to use YUM command for searching and installing packages. For example we search for Zabbix package using epel repo, lets see it is available or not under epel.

# yum --enablerepo=epel info zabbix

Sample Output

Available Packages
Name       : zabbix
Arch       : i386
Version    : 1.4.7
Release    : 1.el5
Size       : 1.7 M
Repo : epel
Summary    : Open-source monitoring solution for your IT infrastructure
URL        : http://www.zabbix.com/
License    : GPL
Description: ZABBIX is software that monitors numerous parameters of a network.

Let’s install Zabbix package using epel repo option –enablerepo=epel switch.

# yum --enablerepo=epel install zabbix

Note: The epel configuration file is located under /etc/yum.repos.d/epel.repo.

This way you can install as many as high standard open source packages using EPEL repo.

    Nice article. Helped me sorting epel installation.

  5. Anand says:

    After the installation of epel, commands like service, chkconfig, iptables and others have stopped working with an error that “command not found”. Now the only way to run these command is sbin/service. Any idea why?

  6. Steve says:

    Now I can use a stable version of Linux as a workstation. Fedora got too unreliable for me.

    I enabled my epel on my centos 6.4 box. Since we installed Oracle Linux the output looks different from what you post here.
    Is this ok ?

    I have a redhat 5.5 i386, Perform all steps in this tutorial but when trying to install net-snmp gives me the following error:

    A common cause of this error code is due to having an Mistakenly setup

    on the account as a universal default, you can disable this key and retry to avoid
    Requiring a Management entitlement.

    • Ravi Saive says:

      It seems your RedHat 5.5 system haven’t registered at RHN Network and it also indicates that your organization don’t have enough entitlements to register your server ot Red Hat Network. Please raise a ticket at RHN support team.

    • Randeep says:

      It seems the command string you are using “# Yum – enablerepo = net-snmp EPEL info” isn’t correct (in comparison to the one provided in above screenshot), please check the same.

  14. monkeynote says:

    hello! I am using Oracle Linux 7 and i followed epel repo instruction for 64 bit.

    wget http://dl.fedoraproject.org/pub/epel/beta/7/x86_64/epel-release-7-0.2.noarch.rpm
    rpm -ivh epel-release-7-0.2.noarch.rpm

    however, i cant see the Epel repo when i execute yum repolist.

    I also checked the files in /etc/yum.repos.d/ and epel.repo is not there.

    • Ravi Saive says:

      Please run the following command and post the output here. If you see epel-release, that means epel is installed correctly.

      # rpm -q epel-release

    Thank you very much for the post.

    I’ve been trying to install packstack on a Centos 6.6 and have experienced some issues due to epel repo. Thanks to your last Note on the Sample OUTPUT I have enabled the repo list for all the other packages since this was tough to do it for all the packages, and it’s working. I can see all of the packages installing.
