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.

Now that you have a clear idea of how to manage software packages, here are some exercises that will contribute further to your learning.

  1. Make a list of all the packages installed on your system.
  2. Find the sources of an open source program that you love and build it from source.
  3. Add support for flatpaks on your Ubuntu system.
  4. Add support for snaps on your CentOS system.
  5. Test other distributions and use their package managers. We recommend that you try openSUSE and, if you feel confident, Arch Linux.

No hints this time, as we want you to discover all the ups and downs of package management on Linux.
