[[email protected] ~]$ sudo vim /etc/sudoers
We trust you have received the usual lecture from the local System
Administrator. It usually boils down to these three things:

#1) Respect the privacy of others.
#2) Think before you type.
#3) With great power comes great responsibility.
[sudo] password for admin:
admin is not in the sudoers file. This incident will be reported.
切换至root用户下
[[email protected] ~]$ su root
Password:
[[email protected] admin]# ls -l /etc/sudoers
-r--r-----. 1 root root 4328 Oct 30 10:38 /etc/sudoers
[[email protected] admin]# chmod -v u+w /etc/sudoers
mode of ‘/etc/sudoers’ changed from 0440 (r--r-----) to 0640 (rw-r-----)
[[email protected] admin]# ls -l /etc/sudoers
-rw-r-----. 1 root root 4328 Oct 30 10:38 /etc/sudoers
[[email protected] admin]# vim /etc/sudoers
在 root ALL=（ALL） ALL 后面加上 username ALL = （ALL） ALL，其中username表示用户名
[[email protected] admin]# chmod -v u-w /etc/sudoers
mode of ‘/etc/sudoers’ changed from 0640 (rw-r-----) to 0440 (r--r-----)
[[email protected] admin]# ls -l /etc/sudoers
-r--r-----. 1 root root 4438 Mar 11 09:34 /etc/sudoers
退出root用户
[[email protected] admin]# exit
exit
[[email protected] ~]$
添加用户
先切换至root用户下
adduser jiangshan
passwd jiangshan
adduser jinyan
passwd jinyan
chmod -v u+w /etc/sudoers
vim /etc/sudoers
在这一行root ALL=(ALL) ALL下
jiangshan ALL=(ALL) ALL # add by jiangshan with hands
jinyan ALL=(ALL) ALL # add by jiangshan with hands
chmod -v u-w /etc/sudoers
退出root用户
exit
