OPS635 Lab 2 : System Configuration Management using Ansible
=OPS635 Lab 2 : System Configuration Management using Ansible=
==Overview==
In an enterprise environment, the existence of different hardware and Operating Systems operating systems running on production servers is very common. You may find the same software running on different OS OSes and even different hardware platforms. To manage the software configuration on different platforms by using a script, your script would have to be aware of and account for their differences. Your scripts would need to be written in way that they know how to query the operating environment and execute the appropriate installation and configuration actions based on the operating environment it is running on.  There are commercial and open source configuration management systems which aware of and know how to handle such difference in operating platforms. "'''Ansible" ''' is another a CMS (Content Management System) that we are going to study for this lab. In this lab, we will start by trying to convert the script that you have written for configuringNagios on Centos7 CentOS 7 to an Ansible playbook, test it on your testing environment and then deploy it to a new VM. 
==Investigation 1: Installing Ansible on Your Host Machine==
*Install the Ansible package on your host machine.
==Investigation 2: Creating an Ansible Playbook==
*Convert the installation script/puppet manifest from the previous labs into an ansible Ansible playbook that will configure a centos CentOS VM and another non-centos CentOS VM as nagios Nagios servers performing the same checks as in lab 1.
==Investigation 3: Applying a Playbook==
*Use the ansible-playbook command to execute your play on both VMs in the same play. If anything goes wrong, fix it and re-run the play. Continue doing so until the play runs successfully.
 
==Submission==
Demonstrate your ansible Ansible playbook working in class, then upload it to blackboardBlackboard.
