But Python 2 remains available in RHEL 8. The default version of Python in RHEL 8 is Python 3.6. Typically you’ll work with your favorite terminal program, a text editor, and probably a version control system to keep track of changes to your content. Your library of modules can reside on any machine, and there are no servers, daemons, or databases required. Ansible then executes these modules (over SSH by default), and removes them when finished. These programs are written to be resource models of the desired state of the system. Ansible works by connecting to your nodes and pushing out small programs, called “Ansible modules” to them. It uses no agents and no additional custom security infrastructure, so it’s easy to deploy – and most importantly, it uses a very simple language (YAML, in the form of Ansible Playbooks) that allow you to describe your automation jobs in a way that approaches plain English.

Pip method of installation is easier to follow and we will get updated packages from pip than installing ansible from yum. We have successfully installed ansible using “pip” installer and tested by running a ping over remote servers. Oel7_prod = group of ~]$ ansible -i hosts -m ping oel7_prodĪ | SUCCESS => Run the ansible by pointing to inventory file using “-i”.

Pip can be called as preferred installer program.
