Install VirtualBox

This is the same as normal software. Just select the location and follow along. I won’t go into details.

2. Create a new virtual machine in VirtualBox

1. Press Ctrl+N to open the new virtual machine window and fill in the relevant information

Name: Fill in according to your needs. Folder: Choose a disk with a larger space to store it. Try not to put it in the system disk such as the C drive. The system disk can be as many T as you want. Type: Choose Linux Version: Choose according to the image

2. Allocate corresponding memory and adjust it according to your needs

3. Create a virtual hard disk (you can choose the second one for the first installation. Of course, if you already have a virtual disk, you can also choose your own. Here, use the second option)

4. Create a virtual hard disk

VDI is the native format of Virtual Box

VMDK was developed by VMware and is also supported by Sun xVM, QEMU, VirtualBox, SUSE Studio, and .NET DiscUtils.

VHD is the native format of Microsoft Virtual PC and is popular in Microsoft products.

5. Choose the space allocation rule according to your needs

6. The path selection is usually here by default in the folder just now. Select the required size by yourself and click Create.

3. Partial configuration of virtual machine

1. Click the newly created virtual machine and click Settings

2. Configure the iso image of centos8.1 to be a virtual CD: Click Storage,點擊存儲-->點擊沒有盤片-->點擊右側紅標的光盤圖標

3. Select choose a disk file and find the ISO file we downloaded earlier

4. Click Open and then click Network, set Network Card 1 to Bridge Network Card and pay attention to the configuration information at the red mark

5. Now you can start the server (there is a small triangle here, it is recommended to click the separate start button to prevent the virtual machine from shutting down automatically when we close the console later)

6. After waiting for the first time to start, the following prompt will pop up to confirm that it is the one we selected and click Start

7 Select install centos linux 8

8 After waiting for loading, you can continue directly

9. Enter the configuration page and confirm the information first

• keyboard is english(us)
• LanguageSupport is English
• Time & Date is Shanghai time zone (see the following figure)
• Software Selection settings (illustration will be provided later)
• installation destination (see diagram below)
• Network settings () See the following diagram

Set the time zone

Set up a minimal installation (because the subsequent work is basically command line, in order to adapt to the minimal installation I choose here)

Confirm that the disk is checked and click done

Network card settings: Turn on the switch at the specified location and click done.

10. After confirming the above, start the installation

11. Wait for the installation and set the root password yourself during the process (you must set it!)

12. After waiting for the installation to complete, click the reboot button, select the device button on the console, click to assign the CD-ROM drive, and then remove the virtual disk (to ensure smooth entry into the system after restarting)

13. After the restart is complete, enter the system and enter the root account password. After successful entry, our system has been installed.

Subsequent supplement

1. If you are testing a virtual machine, it is recommended to turn off the firewall

Disable firewall systemctl stop firewalld.service
Disable boot startup systemctl disable firewalld.service
Check the firewall status and confirm that it is closed systemctl status firewalld.service
