Ansible Commonly Used Modules

On the command line run ansible -m ping all.

Your playbook, webservers.yml should look something like this:

---
# Common Modules Playbook
#

- name: Common Modules Playbook
  become: yes
  hosts: webservers

  tasks:
   - name: Install httpd on webservers
     yum:
      name: httpd
      state: present

In this task all we have to do is add the following to the webservers.yml playbook:

   - name: Start the httpd service
     service:
      name: httpd
      state: started
      enabled: yes

Your playbook, dbserver.yml, should look similar to this:

---

- name: DB server playbook
  become: yes
  hosts: dbservers

  tasks:
   - name: Add the 'dba' user to the dbservers
     user:
       name: dba

You can add to your dbserver.yml playbook something similar to the following:

   - name: Copy required DBA files
     copy:
      src: /root/DBAstuff.txt
      dest: /home/dba/
      owner: dba
      group: dba
      mode: 0600

The final addition to your webserver.yml playbook should look similar to:

   - name: Create index.html
     file:
      path: /var/www/html/index.html
      state: touch

Your admin.yml playbook will look something like this:

---

- name: Use git to clone the Ansible repo
  hosts: admins
  become: yes

  tasks:
   - name: Install git
     yum:
      name: git
      state: present

   - name: Use the git module
     git:
      repo: https://github.com/ansible/ansible.git
      dest: /opt
