Summary

In our first chapter, we focused on the steps involved in downloading and setting up a server. We began by discussing the process of downloading the server’s operating system, which is a crucial step in the setup process. We then delved into the topic of downloading and setting up a hypervisor, which is a virtualization platform that enables the creation of virtual machines. The hypervisor provides an isolated environment for each virtual machine, which allows multiple virtual machines to run on the same physical server.

Moving on, we discussed the importance of package installation commands in the server setup process. These commands allow system administrators to install, upgrade, and remove packages from the server, which are essential for the server to function properly. We also provided an overview of some common package installation commands such as yum.

Finally, in the fourth section, we highlighted the role of informational commands in the server setup process. These commands provide important information about the system, including information about the operating system and the hardware. We covered three common information commands in CentOS, including uname, lsb_release, and hostnamectl, and described their uses and benefits. These information commands are useful for monitoring and troubleshooting the server and ensuring that it is functioning optimally.

In our next chapter, we dive into Linux users and groups management. Essential for system security, stability, and resource allocation, this chapter covers key commands and tools for system administrators to manage users and groups.
