CentOS sets the default startup command line (does not start the graphical interface)

The modification method in centOS is as follows:

1. Log in as root to avoid sudo

2. Open the /etc/inittab file

   #vim /etc/inittab
3. In the default run level setting, you can see that the first line is written as: id:5:initdefault:(The default run level is 5, that is, the graphical
interface )
4. Change the 5 in the first line to 3.

5. After saving the file, restart the system and you can see the text interface that is started.
