Forget the Linux user password and root password processing method

Linux Root has the supremacy of power, once the root password forgotten or stolen, is a very headache, then how to retrieve the root password, I summed it up as follows:

(i) Linux system password cracking

1. Enter edit mode by E in the Grub options menu

2. (press e) Edit kernel line add/init 1 (or/single)

3. Restart by B

4. After entering, execute the following command

#vi/etc/passwd into passwd file

The first line of the root:x:0 .... In the x Delete, become root::0 .... Then save the exit!

In the system at this time the root password is empty.

Modify password

#passwd Root
