Install Ansible on RHEL

Posted byZachary Flower on

As far as automated configuration management tools go, Ansible is “the new hotness” on the market. I admit, I am pretty new to Ansible. Until recently, the majority of my configuration management experience has been rooted solely in Puppet. Tack onto that my recent foray back into the world of Red Hat and I have a lot to learn, starting with getting Ansible installed and running on RHEL. There are two ways to install Ansible—via yum, or directly from source. Yum is obviously easier. However, in the event you are working in a closed system, compiling from source may be your only option. I’ll cover both in this article.

Via Yum

Ansible is not available in the default RHEL repositories, so we need to install Extra Packages for Enterprise Linux (EPEL) in order to install it via yum. To do so, head on over to http://fedoraproject.org/wiki/EPEL and download the newest version of epel-release for your version of RHEL. Once you’ve downloaded that file, navigate to the download location in a terminal and install the RPM using the following command:

sudo rpm -i epel-release-latest-7.noarch.rpm

After installing EPEL, you need to update your package list. This tells yum about all the new packages you can install.

sudo yum update

And that’s it! Well, not really. We still need to install Ansible, but we’re done with the setup portion. Installing Ansible via yum works much the same way as any other yum package. Simply pop open a terminal and run the following command:

sudo yum install ansible

Now, we are done. To test things out, simply ping your Ansible server on localhost. You should receive a “pong” in response.

ansible localhost -m ping

Via Source

If using third-party package repositories is impractical or impossible, your next best option is compiling Ansible via source. While this seems like a much more involved process, it is just as straightforward as the yum install. To begin, let’s clone the GitHub repository:

git clone git://github.com/ansible/ansible.git --recursive
cd ./ansible
git submodule update --init --recursive

Once the Ansible repository is finished downloading, we need to install some dependencies. First, we need to install Python via yum:

sudo yum install python

Next, we need to install a few required Python modules:

sudo easy_install pip

And finally, we simply need to install Ansible to our system:

sudo make install

Now, like before, simply run the ping command to test our newly installed Ansible!

ansible localhost -m ping

And that’s it! Ansible is now ready to rock and roll on Red Hat Enterprise Linux! For more in-depth information about properly configuring and using Ansible, head on over to their website at https://www.ansible.com/ .
