How To: Install Ansible on Red Hat Enterprise Linux 7 (RHEL 7)

For some time now you have been able to download and use for personal development Red Hat Enterprise Linux 7 as part of the “No-cost RHEL Developer Subscription” programme.

There are plenty of tutorials out there on how to install Ansible on RHEL and other Linux variations so this guide serves as the process I went through to install & configure Ansible on a freshly deployed RHEL 7 instance.

Step 0 – Prepping RHEL 7

If you have just downloaded the RHEL 7 ISO as part of the developer subscription model we will need to perform some initial tasks to get it up to scratch

  1. Authenticate your subscription
    subscription-manager register --username your_username --password your_password
  2. Update the OS
    yum update && yum upgrade
  3. Let’s install some classics such as ifconfig & wget
  4. We also need access to the “Extra Packages for Enterprise Linux” for downloading packages outside the normal channels

So at this point we should have a RHEL 7 instance ready to go.

Step 1 – Installing Python, Python Tooling & Ansible

  1. We’ll install Python first
    sudo yum install python
  2. Next we’ll install PIP which is a “package management system used to install and manage software packages written in Python”
    sudo yum install python-pip
  3. Now we need to upgrade it
    sudo pip install --upgrade pip
  4. Next we’ll use PIP to install some liraries and modules for python & Ansible
  5. And finally we will install Ansible
    sudo yum install ansible
  6. To confirm that it has been installed correctly we’ll execute
    ansible --version
    Which should generate the following output

    Done! We now have a working Ansible installation on Red Hat Linux 7!
