Overview of this book

Ubuntu is a Debian-based Linux operating system, and has various versions targeted at servers, desktops, phones, tablets and televisions. The Ubuntu Server Edition, also called Ubuntu Server, offers support for several common configurations, and also simplifies common Linux server deployment processes. With this book as their guide, readers will be able to configure and deploy Ubuntu Servers using Ubuntu Server 16.04, with all the skills necessary to manage real servers. The book begins with the concept of user management, group management, as well as file-system permissions. To manage your storage on Ubuntu Server systems, you will learn how to add and format storage and view disk usage. Later, you will also learn how to configure network interfaces, manage IP addresses, deploy Network Manager in order to connect to networks, and manage network interfaces. Furthermore, you will understand how to start and stop services so that you can manage running processes on Linux servers. The book will then demonstrate how to access and share files to or from Ubuntu Servers. You will learn how to create and manage databases using MariaDB and share web content with Apache. To virtualize hosts and applications, you will be shown how to set up KVM/Qemu and Docker and manage virtual machines with virt-manager. Lastly, you will explore best practices and troubleshooting techniques when working with Ubuntu Servers. By the end of the book, you will be an expert Ubuntu Server user well-versed in its advanced concepts.

Clonezilla essentially allows you to create hard disk images, similar to paid tools such as Acronis. It can be used as either bootable live media, or it can be installed on a server and clients can reach it via Preboot eXecution Environment (PXE) boot.

Clonezilla itself is not actually related to Ubuntu in any way, but I bring it up in this book because this tool is extremely useful and a disk imaging solution is a very worthy aspect of a good deployment scheme. Using Clonezilla, you can use disk images to greatly reduce setup time, and also to back up complex setups. For example, imagine that you typically have a check-list of 20 configuration tweaks that need to be made to each server before you put one into production. With Clonezilla, you can set...
