Problem Statement

Nautilus Application development team wants to test the Apache and PHP setup on one of the app servers in Stratos Datacenter. They want the DevOps team to prepare an Ansible playbook to accomplish this task. Below you can find more details about the task.

There is an inventory file ~/playbooks/inventory on jump host.

Create a playbook ~/playbooks/httpd.yml on jump host and perform the following tasks on App Server 1.

a. Install httpd and php packages (whatever default version is available in yum repo).

b. Change default document root of Apache to /var/www/html/myroot in default Apache config /etc/httpd/conf/httpd.conf. Make sure /var/www/html/myroot path exists (if not please create the same).

c. There is a template ~/playbooks/templates/phpinfo.php.j2 on jump host. Copy this template to the Apache document root you created as phpinfo.php file and make sure user owner and the group owner for this file is apache user.

d. Start and enable httpd service.

Note: Validation will try to run the playbook using command ansible-playbook -i inventory httpd.yml, so please make sure the playbook works this way without passing any extra arguments.

Solution:

  1. Navigate to the Playbooks Directory:

    cd ~/playbooks

  2. Inspect Inventory File:

    cat inventory
      stapp01 ansible_host=172.16.238.10 ansible_ssh_pass=Ir0nM@n ansible_user=tony
  stapp02 ansible_host=172.16.238.11 ansible_ssh_pass=Am3ric@ ansible_user=steve
  stapp03 ansible_host=172.16.238.12 ansible_ssh_pass=BigGr33n ansible_user=banner

  3. Inspect Templates Directory:

    cd templates/
ls
 phpinfo.php.j2

  4. Create the Playbook:

    Create the playbook file httpd.yml in the ~/playbooks/ directory with the following content:

    - hosts: stapp01
  become: yes
  tasks:
  - name: Install Packages
    package:
      name:
        - httpd
        - php
      state: latest

  - name: Create document root
    file:
      path: /var/www/html/myroot
      state: directory
      group: apache
      owner: apache
      mode: '0755'

  - name: Change the document root
    replace:
      path: /etc/httpd/conf/httpd.conf
      regexp: 'DocumentRoot "/var/www/html"'
      replace: 'DocumentRoot "/var/www/html/myroot"'

  - name: Copy template phpinfo.php.j2
    ansible.builtin.template:
      src: phpinfo.php.j2
      dest: /var/www/html/myroot/phpinfo.php
      owner: apache
      group: apache

  - name: Start and enable the httpd service
    service:
      name: httpd
      state: started
      enabled: true

  5. Execute the Playbook:

    Run the playbook using the following command:

    ansible-playbook -i inventory httpd.yml

Validation of Output:

Upon successful execution, you should see output indicating that all tasks have completed successfully. The expected output should be:
