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 ansible command can be used to install Ansible. However, be aware that this will setup Ansible to use Python version 2.7.5. Python 2.7 reached it's end of life support in January of 2020. For this reason, it is preferrable to use pip3 to install Ansible. The pip3 --version can be used to determine if pip3 is installed. If pip3 is installed, something like this should be displayed. If pip3 is not installed, refer to Installing PIP on Linux CentOS.

pip3 --version

pip 9.0.3 from /usr/lib/python3.6/site-packages (python 3.6)

 

The hash command caches the paths to commands, and if a command is relocated then bash will not pick it up unless that cache is cleared. Issue the following command to clear Ansible from the cache.

hash -d ansible

 

Use pip3 to install ansible.

pip3 install --user ansible

 

The pip3 list command can be used to ensure that Ansible was installed. In this example, Ansible version 2.9.12 is installed.

pip3 show ansible

Name: 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). When installing Ansible using pip (or from source), the config file should return None. In this scenario, you can create the /etc/ansible directory (mkdir /etc/ansible) and the ansible.cfg file (touch /etc/ansible/ansible.cfg).

ansible 2.9.12
  config file = None
  configured module search path = ['/home/jeremy.canfield/.ansible/plugins/modules', '/usr/share/ansible/plugins/modules']
  ansible python module location = /usr/local/lib/python3.6/site-packages/ansible
  executable location = /usr/local/bin/ansible
  python version = 3.6.8 (default, Apr  2 2020, 13:34:55) [GCC 4.8.5 20150623 (Red Hat 4.8.5-39)]
