How to solve the root user password error in linux

Today, what I want to share with you is how to solve the root user password error in linux. I believe many people don't know much about it. In order to make you understand better, I summed up the following contents and looked down together. I'm sure you'll get something.

Question:

Enter the command su root, but enter the password incorrectly.

Reason:

Because the newly installed Linux system does not set a password for root.

Solution:

First enter the following command:

Sudo passwd root

[sudo] password for sam (user name): enter the password of the current login liunx user name

Enter new UNIX password: enter the new password and confirm that the password at this time is the new root password

Retype new UNIX password: reconfirm the new root password

Pop-up: passwd: password updated successfully (password updated successfully)

Then enter the root permission, as follows:

Su root

Switch to an ordinary user, such as the user name configured by yourself is sam.

Su sam
