Add Epel source under CentOS

Rhel and his derivative distributions such as CentOS, Scientific Linux in order to stabilize, the official RPM repository provided RPM package is often very lag, of course, this is understandable, after all, this is the server version, security and stability is the focus, The official RPM repository provided by the RPM package is not rich enough, many times need to compile themselves that too hard, and epel just can solve both aspects of the problem.

What is Epel?
The full name of
EPEL is called Extra Packages for Enterprise Linux  . Epel is a project built by the Fedora community to deliver high-quality software packages for RHEL and derivative distributions such as CentOS, scientific Linux, and more. After the Epel is loaded, it is equivalent to adding a third-party source.

If you know rpmfusion.org, it is appropriate to compare rpmfusion, rpmfusion mainly provides a large number of RPM packages for the desktop distribution, and EPEL A large number of rpm packages are available for the server version, and most rpm packages are in the official Repository is not found in .

Another feature is that most rpm packages are more than official repository of rpm package version to be new , such as my previous days on the CentOS installation of Php,rhel for stability still in the 5.1.6 version, I remember this is the first half of last year's version, and PHP The latest version has reached 5.3.2, if the phpMyAdmin is installed on the basis of php5.1.6, it will prompt PHP version is too low, this time, the newer PHP rpm provided in Epel can be handy.
