How to install & configure epel repo on Centos 6.x (64 Bit):



Download epel RPM:
 wget http://dl.fedoraproject.org/pub/epel/6/x86_64/epel-release-6-8.noarch.rpm
wget http://rpms.famillecollet.com/enterprise/remi-release-6.rpm
 
Install epel rpms:
rpm -ivh  epel-release-6-8.noarch.rpm
rpm -ivh  remi-release-6.rpm

Update rpms if previously installed:
sudo rpm -Uvh remi-release-6*.rpm epel-release-6*.rpm

We should see some additional repo definitions under the /etc/yum.repos.d directory.
 # ls -1 /etc/yum.repos.d/epel* /etc/yum.repos.d/remi.repo
 /etc/yum.repos.d/epel.repo
/etc/yum.repos.d/epel-testing.repo
/etc/yum.repos.d/remi.repo

Enable the remi repository:
Open the /etc/yum.repos.d/remi.repo repository file using a text editor of your choice:

vi /etc/yum.repos.d/remi.repo

Edit the [remi] portion of the file so that the enabled option is set to 1.
