Linux is free and open source. It is based on Unix. It is a multi-user and multi-tasking operating system. Anyone can modify its code and pages. , the main purpose is to avoid commercial restrictions, and deploying the server on a Linux system will be more efficient, stable and secure. (Recommended learning: linux operation and maintenance)

Linux was originally designed by Linus Torvalds, a student at the University of Helsinki in Finland, as a personal hobby in 1991. It officially adopted the GPL protocol in 1994.
GPL: General Public License, which ensures that software is free to all users and anyone can modify the software code. It is applicable to most free software foundations.

Its predecessor is Red Hat Linux, which allows anyone to freely modify and redistribute it. It is managed and controlled by the Fedora Foundation. Due to the poor stability of Fedora, it is generally only used for desktop applications.
Debian: Born in 1993, it is jointly maintained by many developers. It is currently the system that most abides by the Linux GPL agreement. Because it is text-based, the operation is cumbersome and the use process is particularly annoying. It is relatively simple. In other words, as a server platform, Debian is known for its stability.
Linux has the program interface and operation method of the Unix system, and also inherits the stability and efficiency of Unix.
It is common for a host with Linux installed on the network to run continuously for more than a year without crashing or shutting down. However, Linux does not have to bear huge copyright fees like ordinary Unix, and it does not It needs to be used on dedicated expensive hardware;
Linux can be executed on a general i386 PC and has high performance. It naturally absorbs the program resources and users accumulated on Unix over the past few decades. In addition, the copyright of GPL allows everyone to freely distribute the source code of Linux and modify the program according to their own needs, making Linux a very popular multi-person multi-tasking, free, stable, high-efficiency, and can be used on i386, etc. , Sparc, Alpha, Mips, PPC and other operating systems that execute on many different computer system platforms.
