Overview of this book

Linux plays a significant role in modern data center management and provides great versatility in deploying and managing your workloads on-premises and in the cloud. This book covers the important topics you need to know about for your everyday Linux administration tasks. The book starts by helping you understand the Linux command line and how to work with files, packages, and filesystems. You'll then begin administering network services and hardening security, and learn about cloud computing, containers, and orchestration. Once you've learned how to work with the command line, you'll explore the essential Linux commands for managing users, processes, and daemons and discover how to secure your Linux environment using application security frameworks and firewall managers. As you advance through the chapters, you'll work with containers, hypervisors, virtual machines, Ansible, and Kubernetes. You'll also learn how to deploy Linux to the cloud using AWS and Azure. By the end of this Linux book, you'll be well-versed with Linux and have mastered everyday administrative tasks using workflows spanning from on-premises to the cloud. If you also find yourself adopting DevOps practices in the process, we'll consider our mission accomplished.

Chapter 1: Installing Linux

The recent years have marked a significant rise in the adoption of Linux as the operating system of choice for both server and desktop computing platforms. From enterprise-grade servers and large-scale cloud infrastructures to individual workstations and small-factor home appliances, Linux has become an ever-present platform for a wide range of applications.

The prevalence of Linux, perhaps now more than ever, brings into the spotlight much-needed administration skills for a growing community of system administrators and developers. In this book, we take a practical approach to Linux administration essentials, with the modern-day system administrator, DevOps, or developer in mind.

In this first chapter, we'll guide you through the Linux installation process, either on physical hardware (bare metal) or using a Virtual Machine (VM). We'll take you further with a few case studies on choosing a Linux distribution based on functional requirements. Along the way, we introduce you to the Linux graphical user interface with some hands-on examples of configuring GNOME and KDE. Finally, we build a Linux workstation suitable for our daily computing needs.

Here are the topics we cover in this chapter:

  • The Linux operating system
  • Linux distributions
  • Choosing the right Linux distribution
  • Installing Linux - the basics
  • The Windows Subsystem for Linux (WSL)
  • Installing Linux graphical user interfaces
  • Setting up and using the Linux workstation
