Create an Ansible vault to store user passwords as follows:

* The name of the vault is valut.yml

* The vault contains two variables as follows:

- dev_pass with value wakennym

- mgr_pass with value rocky

* The password to encrypt and decrypt the vault is atenorth

* The password is stored in the file /home/admin/ansible/password.txt

Install and configure ansible

User sandy has been created on your control node with the appropriate permissions already, do not change or modify ssh keys. Install the necessary packages to run ansible on the control node. Configure ansible.cfg to be in folder /home/sandy/ansible/ansible.cfg and configure to access remote machines via the sandy user. All roles should be in the path /home/sandy/ansible/roles. The inventory path should be in /home/sandy/ansible/invenlory.

You will have access to 5 nodes.

node1.example.com

node2.example.com

node3.example.com

node4.example.com

node5.example.com

Configure these nodes to be in an inventory file where node I is a member of group dev. nodc2 is a member of group test, node3 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 playbook called timesvnc.yml in /home/sandy/ansible using rhel system role timesync. Set the time to use currently configured nip with the server 0.uk.pool.ntp.org. Enable burst. Do this on all hosts.

Create a playbook /home/bob /ansible/motd.yml that runs on all inventory hosts and docs the following: The playbook should replaee any existing content of/etc/motd in the following text. Use ansible facts to display the FQDN of each host

On hosts in the dev host group the line should be "Welcome to Dev Server FQDN".

On hosts in the webserver host group the line should be "Welcome to Apache Server FQDN".

On hosts in the database host group the line should be "Welcome to MySQL Server FQDN".

Create a jinja template in /home/sandy/ansible/ and name it hosts.j2. Edit this file so it looks like the one below. The order of the nodes doesn't matter. Then create a playbook in /home/sandy/ansible called hosts.yml and install the template on dev node at /root/myhosts

Create a file called specs.empty in home/bob/ansible on the local machine as follows:

HOST=

MEMORY=

BIOS=

VDA_DISK_SIZE=

VDB_DISK_SIZE=

Create the playbook /home/bob/ansible/specs.yml which copies specs.empty to all remote nodes' path /root/specs.txt. Using the specs.yml playbook then edit specs.txt on the remote machines to reflect the appropriate ansible facts.

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
