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

Modify file content.

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

Create a playbook called /home/admin/ansible/modify.yml as follows:

* The playbook runs on all inventory hosts

* The playbook replaces the contents of /etc/issue with a single line of text as

follows:

--> On hosts in the dev host group, the line reads: “Development”

--> On hosts in the test host group, the line reads: “Test”

--> On hosts in the prod host group, the line reads: “Production”

Use Ansible Galaxy with a requirements file called /home/admin/ansible/roles/

install.yml to download and install roles to /home/admin/ansible/roles from the

following URLs:

http:// classroom.example.com /role1.tar.gz The name of this role should be balancer

http:// classroom.example.com /role2.tar.gz The name of this role should be phphello

Create a playbook called hwreport.yml that produces an output file called /root/

hwreport.txt on all managed nodes with the following information:

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

--> Inventory host name

--> Total memory in MB

--> BIOS version

--> Size of disk device vda

--> Size of disk device vdb

Each line of the output file contains a single key-value pair.

* Your playbook should:

--> Download the file hwreport.empty from the URL http://classroom.example.com/

hwreport.empty and

save it as /root/hwreport.txt

--> Modify with the correct values.

note: If a hardware item does not exist, the associated value should be set to NONE

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

while practising you to create these file hear. But in exam have to download as per

questation.

hwreport.txt file consists.

my_sys=hostname

my_BIOS=biosversion

my_MEMORY=memory

my_vda=vdasize

my_vdb=vdbsize

Create a playbook called packages.yml that:

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

--> Installs the php and mariadb packages on hosts in the dev, test, and prod host

groups.

--> Installs the Development Tools package group on hosts in the dev host group.

--> Updates all packages to the latest version on hosts in the dev host group.

Create a playbook called webdev.yml in 'home/sandy/ansible. The playbook will create a directory Avcbdev on dev host. The permission of the directory are 2755 and owner is webdev. Create a symbolic link from /Webdev to /var/www/html/webdev. Serve a file from Avebdev7index.html which displays the text "Development" Curl http://nod e1.example.com/webdev/index.html to test

Create the users in the file usersjist.yml file provided. Do this in a playbook called users.yml located at /home/sandy/ansible. The passwords for these users should be set using the lock.yml file from TASK7. When running the playbook, the lock.yml file should be unlocked with secret.txt file from TASK 7.

All users with the job of 'developer' should be created on the dev hosts, add them to the group devops, their password should be set using the pw_dev variable. Likewise create users with the job of 'manager' on the proxy host and add the users to the group 'managers', their password should be set using the pw_mgr variable.

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 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.

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.
