Ansible is a simple open-source automation tool that can automate cloud deployment, application deployment or Linux OS maintenance. Comparing Ansible to other automation tools (i.e. Puppet), it’s the simplest tool, because it’s agentless. Ansible once installed on a control node, connects to a managed node via SSH, which doesn’t require any client applications installed on that node.
Installation of Ansible on Fedora based control node is pretty simple and straightforward, since it can be installed from RPM packages. In this tutorial we are installing Ansible on Fedora 23 via dnf package manager.

1. Locate Ansible package
