1. Introduction to VMware
VMware Workstation is a professional virtual machine designed by VMware. It can run another operating system on any operating system to build multiple virtual computer systems. The operating system originally installed on that computer is called the main operating system, and the operating system installed on the virtual computer is called the guest operating system.
1. Why use a virtual machine?
Linux has powerful functions, but most computers on the market use windows or mac operating systems. As a novice user, it is unrealistic to transfer all of them to Linux under the existing operating system at once, and the virtual machine can complete any switching between the existing operating system and the Linux operating system.
There are four reasons:
1. Build a network environment with a single computer: Under one computer, users can build a small network environment between the host and multiple virtual operating systems, and can perform network configuration, debugging, and network programming test applications.
2. Cross-platform transplantation of software development: can be developed in the windows environment, and then transplanted to Linux or UNIX for cross-platform testing applications 3.
System learning: can switch to the Linux environment to learn and operate at any time in the windows environment
4. Perform dangerous operations: formatting the Linux partition on the virtual machine will not affect the real windows system partition
Two, VMware installation steps

This is the VMware license, choose one and fill it in.
Step10. Click to complete the installation:
Step11. Enter the interface, the tutorial is over;
well, the VMware installation is complete here
3. Introduction to CentOS
CentOS is one of the Linux distributions, which is compiled from the source code released by Red Hat Enterprise Linux in accordance with the open source code regulations. Because it comes from the same source code, some servers that require high stability
use CentOS instead of the commercial version of Red Hat Enterprise Linux. The difference between the two is that CentOS does not contain closed source software.
4. Detailed steps to create Linux on a virtual machine

Five, virtual machine related operations
If you have already installed a Linux operating system, but you want other virtual systems to interoperate, you don't need to reinstall at this time, just clone the installed virtual machine. To clone a virtual machine, use VMware's clone operation;
note:克隆时必须关闭现在正在运行 Linux 操作系统，否则无法克隆。
1. Clone installation demo;
Step1. After closing the Linux operating system, select the virtual machine --> right click --> manage --> clone
Step2. Click [Next Page]
Step3. Click [Next Page] 
Step4. Click [Next Page]
Step5. Set the virtual machine name and select the installation location, and then click [Finish];
Even if the cloned operating system is copied to other people's computers, it is completely consistent and can be used normally.
2. Virtual machine snapshot
In the process of using the virtual operating system, if you accidentally make a misoperation and want to return to a previous state, you can use VMware's snapshot management function, which is actually a switch between states. Snapshots are also easy to set up.
Tips: Select the virtual machine --> right click --> snapshot --> take a snapshot;
snapshot switching demonstration:
the virtual machine just started, without any operations, we define it as snapshot 1, then create a folder on the desktop, and define the state as snapshot 2;
Check the snapshot manager at this time, we can clearly see the operation records;
there is no operation in snapshot 1,
snapshot 2 creates a guan.txt file on the desktop
, but we want to go from snapshot 2 to snapshot 1, just click [Snapshot 1], and then click [Go];
3. Virtual machine migration and deletion
After the virtual machine is successfully installed, it is placed in the folder, so you can directly cut and paste it with Ctrl + X for migration; delete it in VMware and then delete the file.
