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?
- Provides lots of open source packages to install via Yum.
- Epel repo is 100% open source and free to use.
- It does not provide any core duplicate packages and no compatibility issues.
- 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-7-8.noarch.rpm # rpm -ivh epel-release-7-8.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
Sample Output
Loaded plugins: downloadonly, fastestmirror, priorities Loading mirror speeds from cached hostfile * base: centos.aol.in * epel: ftp.cuhk.edu.hk * extras: centos.aol.in * rpmforge: be.mirror.eurid.eu * updates: centos.aol.in Reducing CentOS-5 Testing to included packages only Finished 1469 packages excluded due to repository priority protections repo id repo name status base CentOS-5 - Base 2,718+7 epel Extra Packages for Enterprise Linux 5 - i386 4,320+1,408 extras CentOS-5 - Extras 229+53 rpmforge Red Hat Enterprise 5 - RPMforge.net - dag 11,251 repolist: 19,075
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.
This no longer works if I enter the commands for installation on CentOS 7.
# wget http://dl.fedoraproject.org/pub/epel/7/x86_64/e/epel-release-7-8.noarch.rpm
# rpm -ivh epel-release-7-8.noarch.rpm
The download works but then when ever I run yum I get this unknown repo message I do not know how to get rid of and I do not have access the the epel repo
Loaded plugins: fastestmirror, langpacks
epel/i386/metalink | 40 kB 00:00:00
Could not parse metalink https://mirrors.fedoraproject.org/metalink?repo=epel-7&arch=i386 error was
No repomd file
One of the configured repositories failed (Unknown),
and yum doesn’t have enough cached data to continue. At this point the only
safe thing yum can do is fail. There are a few ways to work “fix” this:
1. Contact the upstream for the repository and get them to fix the problem.
2. Reconfigure the baseurl/etc. for the repository, to point to a working
upstream. This is most often useful if you are using a newer
distribution release than is supported by the repository (and the
packages for the previous distribution release still work).
3. Disable the repository, so yum won’t use it by default. Yum will then
just ignore the repository until you permanently enable it again or use
–enablerepo for temporary usage:
yum-config-manager –disable
4. Configure the failing repository to be skipped, if it is unavailable.
Note that yum will try to contact the repo. when it runs most commands,
so will have to try and fail each time (and thus. yum will be be much
slower). If it is a very temporary problem though, this is often a nice
compromise:
yum-config-manager –save –setopt=.skip_if_unavailable=true
File /var/cache/yum/i386/7/epel/metalink.xml does not exist
@Antony,
Okay, just do yum install epel on the terminal to install Epel repository..
After “yum install epel”, i can’t find epel listed on my “yum repolist”
How do I add it to yum?
@Steven,
It should be yum install epel-release, try this command and see you will get epel under yum repolist or /etc/yum..
this is cool. it helps to setup epel.
Thank you Ravi, you saved my day.
IF Your graph is not showing just change the TIME ZONE under vi /etc/php.ini
I faced the issue because my system time zone and cacti time is different .
Hey Ravi,
You want to update the path for CentOS6 repo
http://dl.fedoraproject.org/pub/epel/6/i386/epel-release-6-8.noarch.rpm
It is moved from old domain “download.fedoraproject.org”
@Tarun,
Thanks for update, but the old links still working, no need to change I think, when required will do..
