2. CentOS installation

This demonstration uses Windows as an example

Note: If you have an Apple Mac M1 pro chip computer, follow this article to install the centos7 virtual machine:

mac pro M1 (ARM) installation: VMWare Fusion and linux (centos7/ubuntu) (1) - Tencent Cloud Developer Community - Tencent Cloud mac released the m1 chip. Its powerful performance has been sought after by many developers, but it is also because The replacement of its architecture has caused problems in the installation of many software or environments. Today we will talk about how to install a Linux virtual machine in m1

The centos official website is located abroad, so downloading must be very slow. There are many mirror addresses in China, so you can download them from domestic ones, such as Tsinghua University open source software mirror station:

Tsinghua University Open Source Software Mirror Station | Tsinghua Open Source Mirror Tsinghua University Open Source Software Mirror Station is committed to providing domestic and on-campus users with high-quality open source software mirrors and Linux mirror source services to help users obtain open source software more conveniently. This mirror site is operated and maintained by Tsinghua University TUNA Association.

Find the appropriate version and download it

However, I have prepared these images. You can download them from the network disk and use them.

Although the latest version is version 8.x, the version 7.x is still used most by enterprises. We can use 7.8.2003:

But I have prepared it for everyone. After downloading the resource, unzip it and open it as follows:

Next start the installation

1. First create a folder specifically for the virtual machine.

I created an all_system folder on drive E to store the installed virtual machine.

2. Open the VM and create a new virtual machine

3. Select typical and next step

4. Install the operating system later and then next step

5. Select Linux, then select CentOS 7 64-bit, next step

6. Give the virtual machine a name and select the folder you just created.

7. The disk size is determined by you based on the remaining capacity of your computer (it can be increased later)

8. Click Finish

9. Open 'Edit virtual machine settings'

10. Select the downloaded or CentOS-7.8-x86_64-DVD-2003.iso file I provided and click OK

11. Click to start the virtual machine

12. When the font changes to white, it means it is selected. Select the first one (the up and down keys can be used to select up and down) and press Enter.

13, then wait, and finally as follows, select Chinese

14. As follows, the default system automatically installs very few software. As a server, less software needs to be installed, but for our own study and research, we still install more.

15, as follows, below GNOME means desktop. We don’t need a desktop to learn Linux. We can’t learn the essence by using a desktop. Moreover, the desktop itself is also a program, which consumes system resources and performance, so desktops are basically not installed on enterprise servers.

16. As follows, we set the partition. Like Windows, Linux also has partitions.

17. As shown below, the default partitioning is automatic, but the effect of distinguishing the default partitions is not good. Whether it should be larger or smaller, we still partition manually.

18, as follows

19. Unlike Windows, Linux has drive letters such as C drive, D drive, etc. It only has one root drive letter, which is /, and the remaining directories are subdirectories under it. First give all space to /

20, then click Finish

21. The following warning may be given, saying that our division is unreasonable. It’s okay. Ignore it for now and click Finish directly.

22. There will be a prompt like this, just click to accept.

23, as follows, turn off the Kdump function, because it is of no use for our current study and will instead occupy memory.

24. Uncheck and click Finish

25. Next set the network and host name

26. After opening, click Finish

27. Next, click to start the installation:

28. As follows, during installation, set a password during the installation process. Linux has a root user by default, which is similar to our administrator user in Windows. It is a super administrator user. We only have such a root user when we come up. Set a password for it. Otherwise, you will still be asked to set a password when you enter the system later.

29. After the setting is completed, press the completion button twice ( weak passwords require two clicks on the completion button )

30. Click Finish again.

31. The password setting is completed, just wait for the installation of the system to be completed.

32. The system is finally installed, click Restart.

33. After the restart is complete, enter the account root

34. Enter the password you set

35. System installation is completed

36. It is best to take a snapshot after the installation is completed, so that it can be restored to the current post-installation appearance in case of damage. If you take a snapshot ,

You can shut down using the command

shutdown -h now

37. Take snapshots

38, then click to take a snapshot

39. This is done. If the system is damaged in the future, or if you want to go back to the way it was just installed, you can do it by restoring the snapshot.

40. After selecting the snapshot you want to restore, click 'Go' below

41. Just select 'Yes' and you will be back to the system state when we took the snapshot.

We found that the Linux system fonts are very small, and it is very inconvenient to operate like this all the time. Next, install the remote connection tool xshell

3. Installation of xshell tool

3-1 Tool download and installation

You can download it from the official website, address:

XSHELL - NetSarang Websitehttps://www.xshell.com/zh/xshell/

1. Double-click to install

2. Next step

3. Next step after accepting the agreement

4. Change the path and then proceed to the next step (try not to install on the C drive by default)

5. The default is enough, click to install.

6. Click Finish

7. Click OK

8. Click OK to update, otherwise use

9. Just go to the next step

10. Next step

11. Completed

12. There is a shortcut on the desktop, double-click to open it.

13. If you have an email address, enter your account number and log in. If you don’t have an email address, register.

14. Confirm

15. Installation successful
