开启Fedora的root用户

Fedora的root用户是默认禁止的，但是我们在使用一些命令时必须用到root用户，要不就得一直加sudo。

下面设置一下开启超级用户
首先，建一个终端。

输入su—
然后输入密码，密码是你在安装Fedora时输入的一个管理密码，回车
输入命令vi /etc/pam.d/gdm
出现文本框,进入插入模式，直接按i键，具体操作如下：（蓝色为需要修改的部分）[test@test ~]$ su -
密码：
[root@test ~]# id
uid=0(root) gid=0(root) 组
=0(root),1(bin),2(daemon),3(sys),4(adm),6(disk),10(wheel) 环境
