Overview of this book

Linux plays a significant role in modern data center management and provides great versatility in deploying and managing your workloads on-premises and in the cloud. This book covers the important topics you need to know about for your everyday Linux administration tasks. The book starts by helping you understand the Linux command line and how to work with files, packages, and filesystems. You'll then begin administering network services and hardening security, and learn about cloud computing, containers, and orchestration. Once you've learned how to work with the command line, you'll explore the essential Linux commands for managing users, processes, and daemons and discover how to secure your Linux environment using application security frameworks and firewall managers. As you advance through the chapters, you'll work with containers, hypervisors, virtual machines, Ansible, and Kubernetes. You'll also learn how to deploy Linux to the cloud using AWS and Azure. By the end of this Linux book, you'll be well-versed with Linux and have mastered everyday administrative tasks using workflows spanning from on-premises to the cloud. If you also find yourself adopting DevOps practices in the process, we'll consider our mission accomplished.

A detailed study of Linux processes and daemons could be a major undertaking. Where worthy volumes on the topic have admirably succeeded, a relatively brief chapter may pale in comparison. Yet in this chapter, we tried to put on a real-world, down-to-earth, practical coat on everything we've considered to make up for our possible shortcomings in the abstract or scholarly realm.

At this point, we hope you are comfortable working with processes and daemons. The skills you've gathered so far should include a relatively good grasp on process types and internals, with a reasonable understanding of process attributes and states. Special attention has been paid to interprocess communication mechanisms, and signals in particular. For each of these topics, we did a practical dive and explored the related commands, tools, and scripts that we thought would be relevant in everyday Linux administration tasks.

The next chapter will take our journey further into working with...
