Install and configure ansible
User bob has been created on your control node. Give him the appropriate permissions on the control node. Install the necessary packages to run ansible on the control node.
Create a configuration file /home/bob/ansible/ansible.cfg to meet the following requirements:
* The roles path should include /home/bob/ansible/roles, as well as any other path that may be required for the course of the sample exam.
* The inventory file path is /home/bob/ansible/inventory.
* Ansible should be able to manage 10 hosts at a single time.
* Ansible should connect to all managed nodes using the bob user.
Create an inventory file for the following five nodes:
nodel.example.com
node2.example.com
node3.example.com
node4.example.com
node5.example.com
Configure these nodes to be in an inventory file where node1 is a member of group dev. nodc2 is a member of group test, nodc3 is a member of group proxy, nodc4 and node 5 are members of group prod. Also, prod is a member of group webservers.

Create a file in /home/sandy/ansible/ called report.yml. Using this playbook, get a file called report.txt (make it look exactly as below). Copy this file over to all remote hosts at /root/report.txt. Then edit the lines in the file to provide the real information of the hosts. If a disk does not exist then write NONE.

Generate a hosts file:
* Download an initial template file hosts.j2 from http://classroom.example.com/
hosts.j2 to
/home/admin/ansible/ Complete the template so that it can be used to generate a file with a line for each inventory host in the same format as /etc/hosts:
172.25.250.9 workstation.lab.example.com workstation
* Create a playbook called gen_hosts.yml that uses this template to generate the file /etc/myhosts on hosts in the dev host group.
* When completed, the file /etc/myhosts on hosts in the dev host group should have a line for each managed host:
127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4
::1 localhost localhost.localdomain localhost6 localhost6.localdomain6
172.25.250.10 serevra.lab.example.com servera
172.25.250.11 serevrb.lab.example.com serverb
172.25.250.12 serevrc.lab.example.com serverc
172.25.250.13 serevrd.lab.example.com serverd
-----------------------------------------------------------------
while practising you to create these file hear. But in exam have to download as per questation.
hosts.j2 file consists.
localhost localhost.localdomain localhost4 localhost4.localdomain4
::1
localhost localhost.localdomain localhost6 localhost6.localdomain6
-------------------------------------------------------------------

Create an ansible vault password file called lock.yml with the password reallysafepw in the /home/sandy/ansible directory. In the lock.yml file define two variables. One is pw_dev and the password is 'dev' and the other is pw_mgr and the password is 'mgr' Create a regular file called secret.txt which contains the password for lock.yml.
