Question 1

Create a file called adhoc.sh in /home/sandy/ansible which will use adhoc commands to set up a new repository. The name of the repo will be 'EPEL' the description 'RHEL8' the baseurl is 'https://dl.fedoraproject.org/pub/epel/epel-release-latest-8.noarch.rmp' there is no gpgcheck, but you should enable the repo.

* You should be able to use an bash script using adhoc commands to enable repos. Depending on your lab setup, you may need to make this repo "state=absent" after you pass this task.

AExplanation:
chmod 0777 adhoc.sh
vim adhoc.sh
#I/bin/bash
ansible all -m yum_repository -a 'name=EPEL description=RHEL8
baseurl=https://dl.fedoraproject.org/pub/epel/epel-release-latest-8.noarch.rmp
gpgcheck=no enabled=yes'

Answer : A

Answer : A

Question 3

===================================================================================

control.realmX.example.com _ workstation.lab.example.com

node1.realmX.example.com _ servera.lab.example.com

node2.realmX.example.com _ serverb.lab.example.com

node3.realmX.example.com _ serverc.lab.example.com

node4.realmX.example.com _ serverd.lab.example.com

node5.realmX.example.com

- username:root, password:redhat

- username:admin, password:redhat

note1. don't change 'root' or 'admin' password.

note2. no need to create ssh-keygen for access, its pre-defined

note3. SELinux is in enforcing mode and firewalld is disabled/stop on whole managed hosts.

===================================================================================

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

-------------------------------------------------------------------

AExplanation:
Solution as:
# pwd
/home/admin/ansible
# wget http://classroom.example.com/hosts.j2
# vim hosts.j2
127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4 ::1
localhost localhost.localdomain localhost6 localhost6.localdomain6
{% for host in groups['all'] %}
{{ hostvars[host]['ansible_facts']['default_ipv4']['address'] }} {{ hostvars[host]
['ansible_facts']['fqdn'] }} {{ hostvars[host]['ansible_facts']['hostname'] }}
{% endfor %}
:wq!
