Book Description

Ubuntu Server is taking the server world by storm - and for a good reason! The server-focused spin of Ubuntu is a stable, flexible, and powerful enterprise-class distribution of Linux with a focus on running servers both small and large.

Mastering Ubuntu Server is a book that will teach you everything you need to know in order to manage real Ubuntu-based servers in actual production deployments. This book will take you from initial installation to deploying production-ready solutions to empower your small office network, or even a full data center. You'll see examples of running an Ubuntu Server in the cloud, be walked through set up popular applications (such as Nextcloud), host your own websites, and deploy network resources such as DHCP, DNS, and others. You'll also see how to containerize applications via LXD to maximize efficiency and learn how to build Kubernetes clusters. This new fourth edition updates the popular book to cover Ubuntu 22.04 LTS, which takes advantage of the latest in Linux-based technologies.

By the end of this Ubuntu book, you will have gained all the knowledge you need in order to work on real-life Ubuntu Server deployments and become an expert Ubuntu Server administrator who is well versed in its feature set.

What you will learn

• Install Ubuntu Server on physical servers and on the Raspberry Pi
• Deploy Ubuntu Server in the cloud and host websites on your own server
• Deploy your applications to their own containers and scale your infrastructure
• Set up popular applications such as Nextcloud
• Automate deployments and configuration with Ansible to save time
• Containerize applications via LXD to maximize efficiency
• Discover best practices and troubleshooting techniques

Who this book is for

This book is for System Administrators, Site Reliability Engineers, DevOps professionals, enthusiasts, as well as for individuals looking to make a career change and learn the skills they'll need to work with Ubuntu servers. Prior knowledge of Ubuntu is not required but a basic understanding of basic computing concepts is assumed. Some IT administration, Linux, and shell scripting experience is preferred, although the first several chapters will bring newcomers up to speed as well.

What’s new in this edition?

The primary purpose for the fourth edition was to update it for Ubuntu Server 22.04 LTS. This makes the latest edition a great fit for anyone jumping in to manage Ubuntu Server while getting up to speed with the latest LTS release. Another new aspect of this latest version is that there are matching video lessons from LearnLinuxTV for many of the concepts taught within the book. You will benefit from these concepts that you grasp, and the videos will reinforce what you've learned.

What is the key takeaway of this book?

You’ll take away valuable skills that can be used to manage real Ubuntu servers. And I mean that very literally – Mastering Ubuntu Server is modeled after real-world scenarios that system administrators and engineers actually encounter on a regular basis. For example, if you want to know how to deploy Ubuntu Server, it's covered; if you're looking for guidance on how to deploy a hosted application, it's covered; and if you're tasked with migrating solutions to the cloud, that’s also covered. If your server isn't operating correctly, troubleshooting skills are covered too.

Compared to previous editions, what is different about this edition?

Quite a bit of effort was put into testing each of the examples against Ubuntu 22.04, so there's countless changes and adjustments throughout. Since the previous edition was written, many new educational videos have been released on the LearnLinuxTV YouTube channel, and most of the chapters in this version link to videos from that channel whenever there's a match with the current topic. In fact, many of those videos were updated for Ubuntu 22.04 as well. Therefore, I think Mastering Ubuntu Server is part of a learning platform of its own instead of being just a book.
