Ansible Playbook Essentials

By: Gourav Shah, GOURAV JAWAHAR SHAH

Overview of this book

Ansible Playbook Essentials will show you how to write a blueprint of your infrastructure, encompassing multitier applications using Ansible's playbooks. Beginning with basic concepts such as plays, tasks, handlers, inventory, and YAML Ain't Markup Language (YAML) syntax that Ansible uses, you'll understand how to organize your code into a modular structure. Building on this, you will study techniques to create data-driven playbooks with variables, templates, logical constructs, and encrypted data, which will further strengthen your application skills in Ansible. Adding to this, the book will also take you through advanced clustering concepts, such as discovering topology information about other nodes in the cluster and managing multiple environments with isolated configurations. As you approach the concluding chapters, you can expect to learn about orchestrating infrastructure and deploying applications in a coordinated manner. By the end of this book, you will be able to design solutions to your automation and orchestration problems using playbooks quickly and efficiently.

Configuring WordPress requisites


While creating a role to install WordPress in Chapter 4, Bringing In Your Code – Custom Commands and Scripts, we created tasks to download, extract, and copy the WordPress application. However, that's not enough to launch WordPress, which has the following prerequisites:

  • A web server

  • PHP bindings for a web server

  • The MySQL database and MySQL users

An Nginx web server and MySQL service have already been installed in our case. We still need to install and configure PHP along with the MySQL database and a user required for our WordPress application. To handle PHP requests, we choose to implement the PHP5-FPM handler, which is an alternative to the traditional FastCGI implementation.
