EPEL & REMI Repository on CentOS

EPEL Repository

Adding EPEL Repository to RHEL / CentOS / Scientific Linux 6.x

EPEL is available as rpm, therefore you can install it on your system. You don’t have to manually add any entries on/etc/yum.repos.d/ directory of your system. Since it is available as noarch rpm, you can install it on both 32 and 64 bit systems. I tested this how-to on CentOS 6.5, however it will work on all 6.x versions.

First go to the EPEL repository download page. Download the latest EPEL rpm and install it as shown below.

# wget http://epel.mirror.net.in/epel/6/i386/epel-release-6-8.noarch.rpm
# rpm -Uvh epel-release-6-8.noarch.rpm

Adding EPEL Repository to RHEL / CentOS / Scientific Linux 5.x

First go to the EPEL repository download page. Download the latest EPEL rpm and install it as shown below.

# wget http://epel.mirror.net.in/epel/5/i386/epel-release-5-4.noarch.rpm
# rpm -Uvh epel-release-5-4.noarch.rpm

Now list out the installed repositories using command:

# yum repolist

Sample output:

 * epel: epel.mirror.net.in
 * extras: mirror.leapswitch.com

Install Packages

Now you can install the packages as usual with command:

# yum install bugzilla

Hence bugzilla is not available in the default repositories, you will see that bugzilla is installed from EPEL repository.

Install packages from EPEL repository only

Let us install a package from EPEL repository. I am gonna install bugzilla package from EPEL repository. The below command shows that i disabled all existing repositories and install the httpd package form EPEL repository.

# yum install --disablerepo="*" --enablerepo=epel bugzilla
