ubuntu如何創建root用戶

1、系統信息

liujiaxin01@liujiaxin01-virtual-machine:~/Desktop$ lsb_release -a No LSB modules are available. Distributor ID: Ubuntu Description: Ubuntu 20.04.2 LTS Release: 20.04 Codename: focal

 

2、創建root用戶

liujiaxin01@liujiaxin01-virtual-machine:~/Desktop$ sudo passwd root
New password: 
Retype new password: 
passwd: password updated successfully

 

3、切換至root用戶

liujiaxin01@liujiaxin01-virtual-machine:~/Desktop$ su - root
Password: 
root@liujiaxin01-virtual-machine:~# whoami
root
