Linux 用户添加sudo权限

本文简单介绍下在Linux环境下如何创建一个用户并给此用户赋予sudo权限。

1 root创建测试用户test

[root@ha-4 ~]# useradd test

2 切换test用户检查sudo权限

[root@ha-4 ~]# su - test
[test@ha-4 ~]$ sudo date

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.

3 切换root用户用visudo添加test用户sudo权限

[root@ha-4 ~]# visudo

通过visudo打开/etc/sudoers文件，添加以下行并保存

test    ALL=(ALL)       NOPASSWD: ALL

4 再次切换test用户检查sudo权限

[root@ha-4 ~]# su - test
[test@ha-4 ~]$ sudo date
