Enabling EPEL

EPEL is the most important repository for Enterprise Linux and it contains a lot of additional packages. It's also a safe repository, since no package in EPEL will conflict with packages in the base repository.

To enable EPEL in RHEL/CentOS 7, it is enough to just install the epel-release package. To do so in Ansible, we will use the following:

- name: Ensure EPEL is enabled 
  yum: 
    name: epel-release 
    state: present 
  become: True 

As you can see, we have used the yum module, as we did in one of the first examples of the chapter, specifying the name of the package and that we want it to be present.
