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.

Creating virtual machines


Now the time has come to put your new virtual machine server to the test. In order for us to give this new server a test run, you'll need an ISO of an operating system to install. You can download just about any Linux distribution ISO image, and copy it to your /vm_store/iso directory to make it available for use. You can even copy a Microsoft Windows ISO image there and install that; I won't judge you. After you copy the file over to the /vm_store/iso directory, we're ready to begin.

Note

Before continuing, I highly recommend that you set up public key authentication for SSH between your workstation and virtual machine server. If you're using a local connection, you won't need to do this. But when you're connecting to a remote KVM instance, without setting up public key authentication between your workstation and server, you will likely be asked for your SSH password repeatedly. It can be very annoying. If you haven't used public key authentication for SSH yet, please...
