Mastering CentOS 7 Linux Server

Overview of this book

Most server infrastructures are equipped with at least one Linux server that provides many essential services, both for a user's demands and for the infrastructure itself. Setting up a sustainable Linux server is one of the most demanding tasks for a system administrator to perform. However, learning multiple, new technologies to meet all of their needs is time-consuming. CentOS 7 is the brand new version of the CentOS Linux system under the RPM (Red Hat) family. It is one of the most widely-used operating systems, being the choice of many organizations across the world. With the help of this book, you will explore the best practices and administration tools of CentOS 7 Linux server along with implementing some of the most common Linux services. We start by explaining the initial steps you need to carry out after installing CentOS 7 by briefly explaining the concepts related to users, groups, and right management, along with some basic system security measures. Next, you will be introduced to the most commonly used services and shown in detail how to implement and deploy them so they can be used by internal or external users. Soon enough, you will be shown how to monitor the server. We will then move on to master the virtualization and cloud computing techniques. Finally, the book wraps up by explaining configuration management and some security tweaks. All these topics and more are covered in this comprehensive guide, which briefly demonstrates the latest changes to all of the services and tools with the recent shift from CentOS 6 to CentOS 7.

Chapter 3. Linux for Different Purposes

The plans we make to set up a server infrastructure or a data center are generally the same. We always try to organize services between the servers that we are running, respecting our needs. Servers operating on a Linux system can be used to run multiple services at once or just one depending on how much processing power that service will need and its position inside the network. Following the needs of the users, system administrators should always be ready to set up or to take down services in their infrastructure. Usually, for a basic system installation, there will be a number of services already installed but not well configured.

This chapter will cover some of the main Linux services that most users are in need of, and also how to set up, configure, and operate them. Then we are going to explore some of those service's aspects, how to secure them, and how to operate them in the best way possible.

In this chapter, we are going to learn to:
