Ansible - Part 9 - Pbooks to scripting multiple commands in Linux
Haziran 6, 2015 by

Earlier articles, we installed Ansible and added necessary admin users for managing nodes from Ansible server and implemented SSH key authentication to access nodes without password as SSH tunnel. We tested if our Ansible controller is working with pinging nodes and looked at few adhoc commands to centralized server management.

In this article, we will see how to use Ansible playbooks to bring together commands in one script for template way execution.

We use following Ansible yml file template to add our commands. 




tasks:

  - name: Add epel-release repo

    yum:

      name: epel-release

      state: present



  - name: Install nginx

    yum:

      name: nginx

      state: present


Lets see it in a shell example.

USA citadel

In above example, we created a file called "ansible_pbook1.yml" and added our yml template into it. In that first simple "yml" file, we added ping command only and "Ansible-playbook" command used our "yml" and executed our Ansible commands.
