1. Challenge

   Install Ansible on the control host.

   Run the following commands on the control host:

   sudo yum install epel-release

   sudo yum install ansible

2. Challenge

   Create an `ansible` user on both the control host and workstation host being sure to set a password you can remember.

   On each host, run the noted commands below. Make sure you set a password you can remember (you will need it later).

   Assuming you are logged in as cloud_user:

   sudo useradd ansible

   sudo passwd ansible

3. Challenge

   Configure a pre-shared key for Ansible that allows the user to log in from `control` to `workstation` without a password.

   Assuming you are logged into control as cloud_user, run the following commands providing the appropriate passwords when prompted and default options otherwise:

   sudo -i -u ansible (provide cloud_user a sudo password)

   ssh-keygen (accept default options by pressing enter )

   ssh-copy-id workstation (provide ansible user a password)

   logout

4. Challenge

   Configure the Ansible user on the workstation host so that Ansible may sudo without a password.

   1. Log into the workstation host as cloud_user and run the following commands:
      sudo visudo

   • Add text at the end of the file that is opened:
     ansible ALL=(ALL) NOPASSWD: ALL
   • Save file:
     (:wq in vim)
5. Challenge

   Create a simple inventory in `/home/ansible/inventory` consisting of only the `workstation` host.

   1. On the control host as the ansible user run the following commands:

   vim /home/ansible/inventory (note: you may use any text editor with which you are comfortable)

   • Add the text "workstation" to the file and save using (:wq in vim).
6. Challenge

   Write an Ansible playbook in `/home/ansible/git-setup.yml` on the control node that installs `git` on `workstation` then execute the playbook.

   1. On the control host as the ansible user run the following commands:
      vim /home/ansible/git-setup.yml (You may use any text editor with which your are comfortable.)

   • Add the following text to the file:

       --- # install git on target host
       - hosts: workstation
         become: yes
         tasks:
         - name: install git
           yum:
             name: git
             state: latest
   

   • Save (:wq in vim) and quit the text editor.

   • Run ansible-playbook -i /home/ansible/inventory /home/ansible/git-setup.yml.
