Forgotten root Password
I forgot my Red Hat Server root password. What i need to do to recover the root password?
In RedHat Linux, we can recover the root password by log in single-user mode and create a new root password.
Below are the steps:-
- Power on, or reboot your RedHat Machines
- At the boot loader menu, use the arrow keys to highlight the installation you want to edit and type [A] to enter into append mode.

- After that, you should see the screen similar to the following
grub append> ro root=/dev/VolGroup00/LogVol00 rhgb quiet
- Press the Spacebar once to add a blank space, then add the word single and press Enter to tell GRUB to boot into single-user Linux mode.
grub append> ro root=/dev/VolGroup00/LogVol00 rhgb quiet single
- After it finishes loading, you will get a shell prompt
sh-3.2#
- Now you can change the root password by enter the following command
sh-3.2# passwd root
- After that, reboot your machine
sh-3.2# reboot
Now you should able to log in to root with your new changed password.
