This is Linux in one volume!
The complete book covering Linux from A to Z!

CentOS is a clone of RHEL and was the most widely used Linux distribution by universities and companies/organizations that require large-scale servers.
However, in December 2020, Red Hat announced that it would end support for CentOS 8 (with updates until December 31, 2021) and transition to CentOS Stream.
However, CentOS Stream is actually closer to a beta version of RHEL.
This has led many companies/organizations and individuals who have built servers to yearn for a next-generation Linux distribution that can replace CentOS.

After CentOS announced its transition to CentOS Stream, the Linux world has been divided into several Linux distributions.
The person who appeared like a comet at this time was CentOS co-founder Greg Kurtzer.
He created a new Linux distribution called Rocky Linux, a 1:1 counterpart to RHEL, named after another co-founder, the late Rocky McGaugh.
Against this backdrop, Rocky Linux has received full support from Microsoft, Google, Arm, Amazon, and others, becoming the next-generation Linux distribution to replace CentOS.


To fully address these market conditions while maintaining the goal of establishing a practical, hands-on learning environment, 『This is Linux (3rd Edition)』 has been completely revised to Rocky Linux 9.
Therefore, even beginners to Linux and junior engineers can experience everything from the basics of Linux server operation to building mail servers, database servers, web servers, and FTP servers with this one book.
If you want to learn a new distribution in a practical way, don't hesitate and choose "This is Linux (3rd Edition)"!
