Solution to the IP address not being displayed under Linux

Preface

Environment: Create a Linux virtual machine on VMware Workstation

Problem: When checking the IP address through ifconfig on Linux, the IP address cannot be displayed

When you enter ifconfig to view, the IP address is not displayed in the middle, as shown below

The network icon in the lower right corner is found to be disconnected, and it is determined that the problem is caused by the virtual network card not being connected.

Solution:

Step 1

Directly click the icon to connect manually, as shown below

Enter ifconfig again to view the IP address, the problem is solved; but shut down the virtual machine, and then open it again, the network is still disconnected

Step 2

Enter the following command in the command box, the result is as shown below

vi /etc/sysconfig/network-scripts/ifcfg-ens33

(Note: ens33 is the name of the network card)

Click i to enter the file editing state (Note: this needs to be done under the administrator account root);

Change ONBOOT=no to ONBOOT=yes (Note: ONBOOT indicates whether to activate the network card when the system starts);

Click Esc, enter: wq and press Enter to save and exit;

Enter the command service network restart (Note: restart service command), as shown below

When the computer is shut down and restarted again, the problem is solved. The final result is as shown below.
