Solution for Linux virtual machine unable to display IP

1. An IP address is required, so let's first learn to check the IP address of the Centos7 in the virtual machine.

Enter ip query name on the command line: ip a

2. It is found that ens33 does not have the attribute inet, so it is impossible to connect to the virtual machine through the IP address.

Next, take a look at the configuration of the ens33 network card: vi / etc/sysconfig/network-scripts/ifcfg-ens33

Pay attention to the space after vi

Vi is Linux's built-in text editor command to open a file.

3. From the configuration list, you can find that CentOS 7 does not start the network card by default (ONBOOT=no).

Change this item to YES (ONBOOT=yes)

Then press Esc to exit and exit command: wq and then press Enter. (note: wq means to save and then exit)

Then restart the network service: systemctl restart network

4, and then we can enter the ip addr or ip a command to check it.
