First introduction to Linux
The birth of Linux
Linux founder: Linus Torvalds
Linux was born in 1991. When the author was in college, because the founder often needed to browse news and process emails during college, he found that the existing operating system was not easy to use, so he decided to write an operating system in protected mode. This is The prototype of Linux was created when he was 21 years old. Later, with the support of netizens around the world, it is now compatible with a variety of hardware and has become one of the most popular server operating systems.
Linux kernel
The composition of the Linux system is as follows:
- Linux system kernel
- system level application
The kernel provides the core functions of the system , such as: scheduling CPU, scheduling memory, scheduling file system, scheduling network communication, scheduling IO, etc.
System-level applications can be understood as factory-installed programs that allow users to quickly get started with the operating system, such as: file manager, task manager, picture viewing, music playback, etc.
Linux distribution
The kernel is free and open source, which means: Anyone can obtain and modify the kernel, and integrate system-level programs by themselves to provide a complete package of kernel + system-level programs, which is called a Linux distribution.
Anyone can package Linux. There are currently many Linux distributions on the market. The commonly used and well-known ones are as follows:
Different distributions:
- The basic commands are almost the same
- Some operations are different (such as software installation)
There is no need to worry about which distribution to choose. No matter which distribution you use, it is Linux, and what you learn is universal.
Introduction to virtual machines
To learn the Linux system, you need to have a usable Linux system.
It is obviously unrealistic to reinstall your own computer to Linux because the Linux system is not suitable for daily office use.
Therefore, we need to use a virtual machine to obtain an available Linux system environment for learning.
With virtualization technology, we can simulate computer hardware through software in the system and install a real operating system on the virtual hardware. In this way, a complete computer can be virtualized in the computer for us to learn the Linux system.
VMware WorkStation installation
Through virtualization software we can obtain virtual machines.
We choose VMware WorkStation
Download address: https://www.vmware.com/cn/products/workstation-pro.html
Note: Win7 can only download the vmware15 version, and it will not be available in the future.
There is basically nothing to note during the installation process. Note: If you don’t have a license, you can only try it for 30 days.
After the software installation is complete, verify that the network adapter is configured properly.
Install Linux on VMware

Install CentOS operating system in VMware
1. Open the VMware software
2. Follow the steps to create a virtual machine:
3. After clicking Finish, select the KDE graphical interface in the software selection . After a while, the installation of the CentOS system will start. Wait patiently for the installation to complete.
4. Click on the username
5. Enter password
This completes the installation of the Linux system.
