How To Install Ansible on CentOS 7

In this tutorial, we will show you how to install Ansible on CentOS 7. For those of you who didn’t know, Ansible is a radically simple IT automation engine that simplifies cloud computing, configuration management, program setup, intra-service orchestration, and several other IT needs. Ansible uses a very simple language (YAML, in the form of Ansible Playbooks) that allows you to spell out your automation jobs in a way that means plain English. Using Ansible you can control multi-host or device simultaneously using a single command. You don’t need to install the client in the apparatus or each server.

This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘sudo‘ to the commands to get root privileges. I will show you the step-by-step installation of Ansible on a CentOS 7 server.

Prerequisites

• A server running one of the following operating systems: CentOS 7.
• It’s recommended that you use a fresh OS install to prevent any potential issues.
• SSH access to the server (or just open Terminal if you’re on a desktop).
• A non-root sudo useror access to the root user. We recommend acting as a non-root sudo user, however, as you can harm your system if you’re not careful when acting as the root.
