The following column centos system tutorial will introduce you to the CentOS7 networking solution. I hope it will be helpful to friends in need!
When using CentOS7 for the first time, everything is installed. Switch from the command line to the desktop and use firefox to try to see if you can access the Internet.
Sure enough, when you worry about something, it will happen, Murphy's Law.
Getting to the point, how can CentOS7 be able to access the Internet? Generally, there are two situations in which the Internet cannot be accessed:
1. ONBOOT is set to no

Save and exit (1.esc 2 :wq 3. Enter)
Restart network
