First we will install the EPEL repo. For more detail on EPEL repo, we suggest you to read our this post.
Because our system has x86_64 Operating System architecture, we will use only epel repo package for x86_64 . Search epel repo package as per your Operating System architecture(EPEL URL)
wget -r --no-parent -A 'epel-release-*.rpm' http://dl.fedoraproject.org/pub/epel/7/x86_64/e/ rpm -Uvh dl.fedoraproject.org/pub/epel/7/x86_64/e/epel-release-*.rpm
It will create two epel’s repo file inside /etc/yum.repos.d
These are –
1. epel.repo
2.epel-testing.repo
