What is EPEL

EPEL (Extra Packages for Enterprise Linux) is an open-source and free community-based repository project from the Fedora team which provides 100% high-quality add-on software packages for Linux distribution including RHEL (Red Hat Enterprise Linux), CentOS Stream, AlmaLinux, and Rocky Linux.

EPEL project is not a part of RHEL/CentOS but it is designed for major Linux distributions by providing lots of open-source packages like networking tools, sysadmin tools, programming, monitoring, and so on. Most of the EPEL packages are maintained by the Fedora repo.

Why Do We Use the EPEL Repository?

Provides lots of open-source packages to install via Yum and DNF.
Epel repo is 100% open source and free to use.
It does not provide any core duplicate packages and has no compatibility issues.
All EPEL packages are maintained by the Fedora repo.

How to Install EPEL Repository on RHEL 9 Systems

# dnf config-manager --set-enabled crb
# dnf install epel-release epel-next-release

Install EPEL Repo on AlmaLinux 9

# dnf config-manager --set-enabled crb
# dnf install epel-release

How to Install EPEL Repository on RHEL 8 Systems

To install the EPEL repository on RHEL 8-based release systems, use:

Install EPEL Repo on RHEL 8

# subscription-manager repos --enable codeready-builder-for-rhel-8-$(arch)-rpms
# dnf install https://dl.fedoraproject.org/pub/epel/epel-release-latest-8.noarch.rpm

Install EPEL Repo on CentOS Stream 8

# dnf config-manager --set-enabled powertools
# dnf install epel-release

Install EPEL Repo on Rocky/AlmaLinux 8

# dnf config-manager --set-enabled powertools
# dnf install epel-release

How to Install EPEL Repository on RHEL 7 Systems

Install EPEL Repo on RHEL 7

# subscription-manager repos --enable rhel-*-optional-rpms \
                           --enable rhel-*-extras-rpms \
                           --enable rhel-ha-for-rhel-*-server-rpms
# yum install https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm

Install EPEL Repo on CentOS 7

# yum install epel-release

Install EPEL Repo on CentOS 6.x

# yum install epel-release

How Do I Verify EPEL Repo?

Now update the software packages and verify the installation of the EPEL repository using the following commands.

# yum update
# rpm -qa | grep epel

You can also verify that the EPEL repository is enabled on the system by listing all active repositories using the following command.

# yum repolist

To list the software packages that constitute the EPEL repository, run the command.

# dnf --disablerepo="*" --enablerepo="epel" list available
OR
# yum --disablerepo="*" --enablerepo="epel" list available

Alternatively, you can use the following grep command to search for individual package names as shown.

# yum --disablerepo="*" --enablerepo="epel" list available | grep 'htop'
OR
# dnf --disablerepo="*" --enablerepo="epel" list available | grep 'monitorix'

How Do I Use EPEL Repo to Install Packages?

Once the EPEL repository has been successfully installed, a package can be installed using the command.

# dnf --enablerepo="epel" install <package_name>
OR
# yum --enablerepo="epel" install <package_name>

For example, to search and install a package called htop – an interactive Linux process-viewer, run the following command.

# yum --enablerepo=epel info htop

Now, to install the Htop package, the command will be.

# yum --enablerepo=epel install htop

Does the EPEL Repository stay around after the YUM Repository has reached EOL ??

I am tired of depending on YUM and being left hanging after YUM reaches EOL, and then being forced to upgrade just to use Yum. Is EPEL a stable alternative to YUM?

I use my server to solve problems. I’m not into computer systems development.

I like using Centos, but I don’t like the frequency that new versions come out.

Thanks,
Jim

  The following commands will fix this issue..

  If you still see errors, make sure to have repo_gpgcheck is set to 0 in yum.conf file for CentOS.

    Thank you! Turning off the repo gpg check worked. In regards to the security posture of epel, do you think they’ll fix it upstream, soon? Or do I need to get in on the Wednesday meeting to report that I think there’s a change that needs to be made?

Nice article, If we do not have internet on the server. How can we install and configure *epel*? Suppose my desktop is windows and I’ll connect to the server through putty and my servers are in private network. Is there any possible way that we can download all epel rpms and do some kind of local repo config?

  @Manikandan,
  
  Some old NSS is used for SSL within cURL library when you download any package from the web, so it’s rejected. In such case, updating curl combined with nss update will help you..
```
# yum update curl nss nss-util nspr
```
  Hope this helps!

  @Ivan,
  
  Check your network, it seems network issue.. Have you added correct DNS Nameserver entries in /etc/resolv.conf file?

  @Prakash,
  
  I think you’ve installed non-CentOS version of xz package, first remove it.
```
# yum remove xz
```
  And then re-install from the default repositories as shown.
```
# yum install xz
```
  I hope it will fix this issue…

  @Priya,
  
  Please add the DNS Name Servers in /etc/hosts file, if you don’t know DNS, then you can add following line to this file.
```
nameserver 8.8.8.8
```

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

    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..

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”

  @Ankit,
  
  You need to enable your RedHat subscription to get latest package updates from RedHat network, here is the guide to enable RedHat subscription.

  @Vishwajit,
  
  To get package updates from third party repositories like EPEL, you need to first register your RHEL machine to RedHat subscription to enable package updates, here is the guide to do so:

I would say yum update after an repository is installed to bring it to latest version.

  @Ameya,
  
  I totally agreed to your point, yes we should update the repository after installing to bring the software packages to latest version.
