This article mainly introduces how to set the permissions of the/etc/sudoers file in centos. It has certain reference value. Interested friends can refer to it. I hope you will gain a lot after reading this article. Let Xiaobian take you to understand it together.

We see this setting in the/etc/sudoers file:

## Allows people in group wheel to run all commands # %wheel ALL=(ALL) ALL ## Same thing without a password # %wheel ALL=(ALL) NOPASSWD: ALL

What does NOPASSWD: ALL mean? Take a look below:

*#FULLTIMERS can run any command on any host without entering your own password FULLTIMERS ALL = NOPASSWD: ALL*

Very good, that is to say, users who are set to NOPASSWD: ALL can become root users with only sudo, very good!

We can set a user as:

somealreadyexistuser ALL=(ALL) NOPASSWD: ALL

Then somealreadyexistuser can become root at any time!
