Book Description

Linux kernel development is perhaps the world's largest collaborative project to date. With Fedora 31 Essentials, you'll be given easily accessible information to install, use, and administer the Fedora 31 distribution.

The book begins with a concise history of the Linux operating system and the Fedora project. You'll learn how to install Fedora 31 using the dual boot configuration so that it can coexist with Windows on the same drive. After installing Fedora 31, you'll learn how to use GNOME 3 — the desktop environment included with Fedora 31 that helps you navigate through the distribution. As you progress, you'll explore the Cockpit web interface that enables you to perform tasks via a web browser instead of using the command-line. You'll also learn how to manage user access and roles on the Fedora 31 system by adding, removing, and managing users and groups. While learning advanced topics, you'll discover how to use Fedora Modularity to list, install, and remove the software packages that make up a functioning Fedora 31 system.

By the end of the book, you'll have all the information you need to confidently start working with Fedora 31.

What you will learn

  • Manage swap space efficiently to maintain the performance of the Fedora 31 system
  • Perform systemd unit configuration tasks using the systemctl command-line tool
  • Add new disk space to increase the capacity of the root file system
  • Configure a basic Linux-based email environment
  • Configure a Fedora 31 system to act as a web server using Apache
  • Create and manage containers on Fedora 31

Who this book is for

Fedora 31 Essentials is the ideal book if you're looking for essential information on getting started using the Fedora 31 distribution. Whether you are a developer, a system administrator, or a tech lover with no previous Linux administration background, you'll be able to start your adventure with this book.
