In Linux, add the sudo permission and rootsudo to non-root users.
In Linux, when a non-root user is added with the sudo permission, if a non-root user runs the sudo command in linux, a message similar to the following is displayed:

Xxx is not in the sudoers file. This incident will be reported.

Here, xxx is the current user name and the user cannot execute the sudo command. The solution is as follows:

1. Enter the superuser mode. That is, enter "su-". The system will ask you to enter the superuser password and enter the password to enter the superuser mode. (You can also log on directly with the root user );

2. Add the write permission to the configuration file "/etc/sudoers. Enter the following command:

Chmod u + w/etc/sudoers

3. Edit the "/etc/sudoers" file. Enter the command

Vim/etc/sudoers

Press "I" to enter the editing mode and find this line: "root ALL = (ALL) ALL" add "xxx ALL = (ALL) ALL "(here xxx is your user name), save and exit;

4. unwrite the file and enter the command

Chmod u-w/etc/sudoers

You can.
