rocky linux:添加sudoer用户(Rocky Linux 9.1)

一，查看sudo的版本:

[root@img ~]# sudo -V
Sudo version 1.9.5p2
Configure options: --build=x86_64-redhat-linux-gnu --host=x86_64-redhat-linux-gnu
…

如未安装，可以用yum命令安装

 

二，添加用户:

[root@img ~]# groupadd webop
[root@img ~]# useradd -g webop webop
[root@img ~]# ls /home/webop/
[root@img ~]# grep webop /etc/passwd
webop:x:1000:1000::/home/webop:/bin/bash
[root@img ~]# passwd webop
Changing password for user webop.
New password:
Retype new password:
passwd: all authentication tokens updated successfully.

三，使新添加用户可sudo

1,用新添加的用户sudo,会报错

[webop@img ~]$ sudo -i


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

2，把webop添加到wheel组

[root@img ~]# groups webop
webop : webop
[root@img ~]#
[root@img ~]# usermod -aG wheel webop
[root@img ~]# groups webop
webop : webop wheel

再次sudo,成功了

[webop@img ~]$ sudo -i
[sudo] password for webop:
[root@img ~]#

四，为什么把用户加入wheel组后可以sudo?

[root@img ~]# grep wheel /etc/sudoers
## Allows people in group wheel to run all commands
%wheel  ALL=(ALL)       ALL
# %wheel        ALL=(ALL)       NOPASSWD: ALL

说明：可以看到 wheel用户组是被配置为运行所有命令的sudoer

五,查看linux的版本:

[root@blog ~]# cat /etc/redhat-release
