Sometimes, to quickly install a piece of software, we have to resort to using yum. However, not being able to find the yum package can be quite frustrating. Below, we’ll install EPEL to add extra yum repositories as a solution:

Taking CentOS as an example, here is the installation method:
CentOS 6 32-bit:
rpm -ivh http://dl.fedoraproject.org/pub/epel/6/i386/epel-release-6-8.noarch.rpm
CentOS 6 64-bit:
rpm -ivh http://dl.fedoraproject.org/pub/epel/6/x86_64/epel-release-6-8.noarch.rpm
CentOS 5 32-bit:
rpm -ivh http://dl.fedoraproject.org/pub/epel/5/i386/epel-release-5-4.noarch.rpm
CentOS 5 64-bit:
rpm -ivh http://dl.fedoraproject.org/pub/epel/5/x86_64/epel-release-5-4.noarch.rpm
