How to Install Ansible Master Node on CentOS 8

Ansible is a free and open source Configuration and automation tool. We can configure, manage, deploy and automate a large number of client machines from a central machine using Ansible. It communicates over SSH and it doesn’t require installing any agent on the client machines. Ansible uses lots of Ad-hoc commands, playbooks and roles that’s are written in YAML.

This article describes How to Install and configure Ansible Master Node on CentOS8.

Step 1. EPEL Configuration: Since ansible packages are not available in CentOS8 repository. Follow the article How toconfigure EPEL repository on CentOS 8 to enable EPEL repository.

Step 2. Package Installation: Once EPEL repository enabled, run the following command to install Ansible packages:

[root@LC-Ansible-Master ~]# dnf install ansible –y …………………………………………….
