After installing CentOS, your system has only a few repositories, therefore offering a limited range of applications. It is possible and easy to add more repositories that are unofficial but trusted by the community. By doing so, you will access a wide range or applications for your CentOS system.
You have two ways to add more Centos repositories:
*Drop .repo files into your /etc/yum.repos.d/ directory
*Add a repository entry in your /etc/yum.conf file
In this example, we will use yum.conf only, for more consistency.
