Preface

Linux is everywhere, from personal devices to the largest supercomputers, from the computer labs at universities to Wall Street or the International Space Station, and even Mars! Red Hat Enterprise Linux (RHEL for short) is the Linux distribution most used in enterprise environments and knowing how to use it is a key skill for anyone in technology. No matter whether you are completely into managing infrastructure or you are a developer interested in knowing more about the platform you want to deploy on, learning about Linux – and, more precisely, about RHEL – will help you be more effective and could even boost your career.

In this book, we cover the basic RHEL administration skills from a very practical perspective, providing examples and tips that we have learned from our experience in "the trenches." You will be able to follow it from beginning to end, being able to practice with each step while learning about how things are built and why they behave as they do.

We hope you enjoy this book, that you make the most of it, and that you end up, after reading it, with a strong foundation of RHEL administration skills. That's what we wrote it for.

Enjoy reading ... and practicing!
