Ordinary users under centos execute the sudo command and prompt that the permissions are insufficient.

Solution:

Switch to the root user first, and then modify the file:

[daixiang@localhost ~]$ su root
Password: 
[root@localhost daixiang]# vim /etc/sudoers

(Recommended tutorial: centos tutorial )

We need to modify the sudoers file and add the user name to the file:

In command line mode, move the cursor to the beginning of the root ALL=(ALL) ALL line and press yy to copy the line. , press p on the next line to paste, and change root to the user name that needs to be given sudo permissions.

Note that you need to force save and exit (:wq!) when exiting.
