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.

  2. Create the configuration file as a template and deploy it using the template across all servers. Where configurations are split across multiple files, either ensure that all files are managed by Ansible or remove the include statement from the files to ensure parameters cannot be accidentally overridden.
  3. Ansible performs all its operations on the database machine using SSH—hence, there is no need to open your database server to the network to manage it.
  4. You would use the shell module when the native module you need cannot perform the operation you require. For example, older versions of Ansible could do most things on PostgreSQL, but couldn...
