How to install Ansible in RHEL 6.8

Ansible Installation:

-          

•     Epel-release repositry has to be downloaded and installed
•         Using rpm package or yum
•        Check wether epel has been in the list of repolist
•       We are going to install ansible package on control node 

   

      Control node requirements:

•            It should be RHEL 6 and above
•          Linux or any other BSD based Unix system
•           Control node must have Python 2.6 or 2.7 installed.
•           Windows not supported

      Managed host requirements:

•           Ssh connection should be established
•           Must have python 2.4 and later installed.
•          Python-simple.json package must also be installed on RHEL 5.0 managed host.

Ansible will be ready to use . You can check ansible installation by the following command:

            "ansible --version"

      

      Now you take some managed hosts(windows or linux machines) and start playing on that machine by running different ansible playbooks for configuration management.
