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.

Chapter 8: Configuring Linux Servers

In this chapter, you will learn how to configure different types of Linux servers, from Domain Name System (DNS) and Domain Host Configuration Protocol (DHCP) servers to web servers, Samba file servers, File Transfer Protocol (FTP) servers, and Network File System (NFS) servers. All these servers, in one way or another, are powering the backbone of the World Wide Web (WWW). The reason your computer is showing the exact time is because of a well-implemented Network Time Protocol (NTP) server. You can shop online and transfer files between your friends and colleagues thanks to good working DHCP, web, and file servers. Configuring different types of Linux services that power all these servers represents the knowledge base for any Linux system administrator.

In this chapter, we're going to cover the following main topics:

  • Introduction to Linux services
  • Setting up a DNS server
  • Setting up a DHCP server
  • Setting up an NTP server...
