linux 普通用户授权root相关权限

先查看当前用户(test)是否有特权

[test@web01 ~]$ sudo -l

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.
