      abstract = {Study the material in this book to prepare for the RHCE  exam EX294 and to learn how using Ansible within your own  environment improves system administration productivity.  This book covers all of the objectives of the exam and  extends further, ensuring that you know how to use Ansible  to manage Linux. The book uses CentOS, a Red Hat-based  distribution, and Ubuntu instead of using a single Red Hat  distribution. By using the two distributions, you will  understand the power of Ansible and how easily you can deal  with multiple platforms, which is crucial for your  understanding of Ansible in the real world. The book  assumes no previous knowledge of Ansible but some knowledge  of Linux system administration from the command line. You  will learn how to manage Linux systems that are installed  with different distributions, including CentOS Enterprise  Linux 8 and Ubuntu 18.04. You will be able to manage these  systems using ad hoc commands from the command line as well  as creating Ansible playbooks that can be replayed reliably  many times. To save on the code that you have to create,  you will learn how to use Ansible Galaxy to search for and  download roles and collections that are pre-written to  manage elements of your Linux installations. By the end of  this book, you will be able to write efficient and  effective YAML playbooks to manage your entire estate. You  will: Prepare systems so that password-less access can be  used with Ansible remotely Use ad hoc commands to quickly  configure systems Use and format YAML files correctly  Create playbooks that grow in their complexity as your  experience develops Ensure that services are restarted on  configuration changes.},
