1. Modify the configuration file

Use vi editor to modify /etc/sysconfig/network-scripts/ifcfg-eth0

Enter the /etc/sysconfig/network-scripts directory and the command is as follows:

cd /etc/sysconfig/network-scripts

Open the configuration file

vi ifcfg-ens33

(Recommended tutorial: centos usage tutorial)

Your file name may not be this, but just look for ifcfg-ens in front of it.

Change ONBOOT=no in the file to ONBOOT=yes, then save and exit (don’t forget to save!!)

2. Restart the network service

After the modification is completed, you need to restart the network service to take effect. Use the following command.

service network restart
