Add user test
useradd test -d /home/test -m -s /bin/bash -G sudo,users -c 备注内容
set password
passwd test
The above command creates the default group and user home directory at the same time, and adds the sudo and users groups.
Because the sudo group in the /etc/sudoers file is set to be able to perform all sudo operations, if you want to have sudo permissions, you can add the user to the sudo group.
The following is the content of the /etc/sudoers file
#
# This file MUST be edited with the 'visudo' command as root.
#
# Please consider adding local content in /etc/sudoers.d/ instead of
# directly modifying this file.
#
# See the man page for details on how to write a sudoers file.
