Ansible - Install Ansible on Linux

This article describes how to install Ansible but not Ansible Tower. Refer to Install Ansible Tower on Linux if you also want Tower.


Prerequisites

  • Linux OS - The system that Ansible is installed on is known as the control node. Windows is not supported for the control node. Instead, Ansible must be installed on a Linux distribution.
  • Python - The control node must have Python version 2.7 or higher or Python version 3.5 or higher installed. The python --version command can be used to determine if Python is installed and the version that is installed. If Python is not installed, the installation of Ansible will also install Python.

Install

On a Red Hat distribution, the yum install command can be used to install Ansible.

yum install ansible

 

Note that Ansible does not create a daemon, thus the systemctl command will not be used. Instead, Ansible uses SSH to manage remote systems (or a different networking protocol could be used). If the install was successful, the /etc/ansible directory should contain the following.

-rw-r--r--. 1 root root 19179 Jan 29  2018 ansible.cfg
-rw-r--r--. 1 root root  1016 Jan 29  2018 hosts
drwxr-xr-x. 2 root root     6 Jan 29  2018 roles

 

The yum info command should return the following.

            : Ansible is a radically simple model-driven configuration management,
            : multi-node deployment, and remote task execution system. Ansible works

            : on remote nodes. Extension modules can be written in any language and
            : are transferred to managed machines automatically.

 

Additionally, the ansible --version command should return output, like this.

ansible --version
