This article introduces the relevant knowledge of "what methods can be used to retrieve the root password of linux system". In the operation of actual cases, many people will encounter such a dilemma, so let the editor lead you to learn how to deal with these situations. I hope you can read it carefully and be able to achieve something!

Linux root password recovery method 1

Step 1: when the system enters the single-user state, use passwd root to change it directly.

Step 2: boot the system with the installation CD, perform linux rescue status, and attach the original / partition as follows:

Cd / mnt mkdir hd mount-t auto / dev/hdaX (the partition number of the original / partition) hd cd hd chroot. / passwd root

Step 3: remove the local hard drive and hang it on other linux systems in the same way as the second one.

Linux root password recovery method 2

Step 1: when booting the system with lilo: type linux single at the lilo: prompt

The screen shows lilo: linux single

Step 2: enter the linux command line directly.

Step 3: use the following command "vi / etc/shadow" to delete the first line, after root: and before the next:, that is, the line that begins with root. The first line will be similar to root::.. Save

Vi / etc/shadow

Step 4: restart reboot with empty root password.

Method 3 of linux root password recovery

Step 1: when booting the system with grub: when the grub screen appears, use the up and down keys to select the item where you usually start linux (do not select dos), and then press the e key

Step 2: use the up and down keys again to select the item where you normally start linux (similar to kernel / boot/vmlinuz-2.4.18-14 ro root=LABEL=/), and then press the e key

Step 3: modify the command line you see now and add single. The result is as follows:

Kernel / boot/vmlinuz-2.4.18-14 single ro root=LABEL=/ single

Step 4: enter and return, then press the b key to start, you can directly enter the linux command line.

Step 5: use the following command "vi / etc/shadow" to delete the contents of the first line, after root: and before the next:, that is, the line beginning with root. The first line will be similar to root::.. Save

Vi / etc/shadow

Step 6: restart reboot with empty root password.
