EPEL - Extra Packages for Enterprise Linux.
What is Extra Packages for Enterprise Linux (or EPEL)?
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.
What packages and versions are available in EPEL?
There are two ways to use these packages.
One is to download and install the epel rpm file. Once installed the repository information is automatically set, so we dont want know anything more.
The other is to manually configure the repository information. In this we need to know the url to the packages.
Method 1:
Download the epel rpm file that suites your OS.
If you are using an EL6 version: epel-release-6-5.noarch.rpm
If you are using an EL5 version: epel-release-5-4.noarch.rpm
If you are using an EL4 version: epel-release-4-10.noarch.rpm
Method 2:
This is to manually configure the EPEL repository. To do this create a file named *.repo in the /etc/yum.repos.d/ directory.
On a text editor example on vim,
Eg: # vim /etc/yum.repos.d/epel.repo
The contents inside will vary according to the EL version you are using.
For EL6: i386 version,
x86_64 version,
For EL5: i386 version,
x86_64 version,
For EL5 Server: i386 version,
x86_64 version,
For EL5 Client: i386 version,
x86_64 version,
For EL4: i386 version,
x86_64 version,
For EL4 AS: i386 version,
x86_64 version,
For EL4 ES: i386 version,
x86_64 version,
For EL4 WS: i386 version,
x86_64 version,
Import the GPG Keys
Once you have completed the previous step, you need to download and import the RPM GPG keys manually.
For EPEL click here.
For EPEL-6 click here.
For EPEL-5 click here.
For EPEL-4 click here.
Once you click the above link the key will be opened in a new window as a text file and what you have to do is to copy the displayed key and save as a file annywhere say for example in your home dircetory. Alternatively you can also right-click the link and select save link as option to save the text file.
Now Import the key using
You can verify these packages and their keys from the Fedora project's keys page:

Now you can check whether the repo is corrrectly configured by,
