Ansible – Installing Ansible

There are a few of ways to install ansible. For the rest of these articles I'll be running Ansible on Centos 7.

Install Ansible using yum

This is done like this:

$ yum install epel-release
$ yum install ansible

Then check the version of ansible installed:

$ ansible --version

It is actually recommended to install ansible on all client's and just the controller. That way the clients ends up installing all the python related dependencies.

 

However the downside with this approach is that the version of ansible that get's installed is a few versions behind the latest stable version.

Install Ansible from source

To install a newer version, you can run this script as the root user:

[github file = "/Sher-Chowdhury/vagrant-ansible/blob/master/scripts/install-ansible.sh"]

After running the above script, log into the machine as the user, "ansible" and password "vagrant".

Then check what version of ansible is installed:

[ansible@controller ~]$ ansible --version

Set up ansible development environment using vagrant

I created a ansible-vagrant project on github to create your very own ansible vagrant environment. If you are new to ansible, then I recommend this approach. That's because not only will it install a recent version of ansible, but will also set up passwordless ssh access so that your controller can access both client vms without a password prompt.
