Overview of this book

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.

  • 10-GB hard disk (16 GB or more is recommended)

64-bit CPU support is now a requirement, with the only exception being the Raspberry Pi version. This is because Canonical no longer makes versions of Ubuntu available for 32-bit PC and server processors. While this may seem like a downside, all computers sold today support 64-bit operating systems, and consumer CPUs have been 64-bit capable since at least 2003. Even if you have an older PC lying around that you don’t think is capable of running a 64-bit operating system, you’d be surprised—even the later models of the Pentium IV (which is quite old) support this, so this requirement shouldn’t be hard to meet.
