Su root # The system will prompt you to enter the password of the root user

Chmod u + w/etc/sudoers

Vim/etc/sudoers

Find

In the following example

Xiaojing ALL = (ALL: ALL) AL # xiaojing is a new user

(Note: In vim, press: I to enter edit mode. Save: Press ESC to Enter command mode, and then enter ": wq" to save and exit)

Chmod u-w/etc/sudoers
