UbuntuServer adds shutdown users

For various reasons, the server is the most broken. In my opinion, we still need to ensure the comfort of developers and improve their work efficiency. As for servers, the current team size and management model do not require good hardware. Hardware Reliability, especially hard disk reliability, can basically meet your needs. Therefore, it is understandable that a M memory celon assumes this responsibility. Because it is a very old computer, the power supply still does not support ACPI.

Because it is a very old computer, the power supply still does not support ACPI. So some time ago, the power button failed to shut down. Because I remember that there is a PowerUser group in Windows (which may be called this name) to complete this action, so I believe that Linux can also complete this function.

Google Keyword: Ubuntu only allows users to shut down. The simplest solution based on relevant articles is to add a common user to the operator group.

1 usermod-G group user

But still prompt... Is not in the sudoers file.

It seems that the final solution is to modify the file/etc/sudoers.

Modification content:
1. Add the following content under # Cmnd alias specification
Cmnd_Alias SHUTDOWN_CMDS =/sbin/poweroff,/sbin/reboot,/sbin/halt
# Shutdown commands that can be executed by users

2. Add the following under # User priviledge specification
Username ALL = (ALL) NOPASSWD: SHUTDOWN_CMDS

In this way, the user can be shut down, but other administrators cannot work.
