On most Linux distribution, Ansible can be installed either using python3-pip or ansible package.

I’m going to show how to get Ansible installed using the second method on CentOS 8.

First add the EPEL repository to the CentOS 8 server.

# yum localinstall https://dl.fedoraproject.org/pub/epel/epel-release-latest-8.noarch.rpm

Next, install ansible package:

# yum install ansible

Is this ok [y/N]:

Let’s confirm that the installation went ok by checking the version of ansible:

$ ansible --version
ansible 2.8.5
  config file = /etc/ansible/ansible.cfg
  configured module search path = ['/home/student/.ansible/plugins/modules', '/usr/share/ansible/plugins/modules']
  ansible python module location = /usr/lib/python3.6/site-packages/ansible
  executable location = /usr/bin/ansible
  python version = 3.6.8 (default, Oct  7 2019, 17:58:22) [GCC 8.2.1 20180905 (Red Hat 8.2.1-3)]
