RedHat Red Hat Certified Engineer (RHCE) exam for Red Hat Enterprise Linux 8 EX294 Exam Practice Test

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.

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 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.

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 called web.yml as follows:

* The playbook runs on managed nodes in the "dev" host group

* Create the directory /webdev with the following requirements:

--> membership in the apache group

--> regular permissions: owner=r+w+execute, group=r+w+execute, other=r+execute

s.p=set group-id

* Symbolically link /var/www/html/webdev to /webdev

* Create the file /webdev/index.html with a single line of text that reads:

''Development''

--> it should be available on http://servera.lab.example.com/webdev/index.html

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 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
