About this book
systemd is a new type of Linux init system for today’s high-performance, multi-CPU, and multi-core hardware that is now used on all major enterprise-grade Linux distros. The main goal of this Linux systemd book is to help you get an in-depth understanding of systemd to set up your servers securely and efficiently.
This book starts by explaining systemd management, which will help you manage your servers effectively. You’ll then learn how to edit and create your own systemd units, which will be particularly helpful if you need to create custom services or timers and add features or security to an existing service. Next, you'll understand how to analyze and fix boot-up challenges and set system parameters. Later, you'll come across cgroups, that'll help you control system resource usage for both processes and users. The book also shows you how cgroups are structured, the differences between cgroups Version 1 and 2, and how to set resource limits on both. Finally, you'll learn about the systemd way of performing time-keeping, networking, logging, and login management. You'll discover how to configure servers accurately and gather system information to analyze system security and performance.
By the end of this Linux book, you’ll be able to efficiently manage all aspects of a server running the systemd init system.
