Hands-On Enterprise Automation on Linux

By: James Freeman

Overview of this book

Automation is paramount if you want to run Linux in your enterprise effectively. It helps you minimize costs by reducing manual operations, ensuring compliance across data centers, and accelerating deployments for your cloud infrastructures. Complete with detailed explanations, practical examples, and self-assessment questions, this book will teach you how to manage your Linux estate and leverage Ansible to achieve effective levels of automation. You'll learn important concepts on standard operating environments that lend themselves to automation, and then build on this knowledge by applying Ansible to achieve standardization throughout your Linux environments. By the end of this Linux automation book, you'll be able to build, deploy, and manage an entire estate of Linux servers with higher reliability and lower overheads than ever before.

Technical requirements

This chapter includes examples, based on the following technologies:

  • Ubuntu Server 18.04 LTS
  • CentOS 7.6
  • Ansible 2.8

To run through these examples, you will need access to two servers or virtual machines running one each of the operating systems just listed, and also, Ansible. Note that the examples given in this chapter may be destructive in nature (for example, they add and remove databases and tables, and change database configuration) and, if run as is, are only intended to be run in an isolated test environment. Once you are satisfied that you have a safe environment in which to operate, let's get started on looking at the installation of new software packages with Ansible.
