Recover Root Password In Liunx Machine
Recover Root Password
Probably the simplest way to solve a forgotten root password problem is to boot your system in the single-user mode.
If you are using LILO, at the LILO boot prompt (graphical LILO users can press Ctrl-x to exit the graphical screen and go to the boot: prompt), and then enter:
Code:
linux single
This will make you the "root" user without asking for a password. Once the system has booted, you can change the root password using the password command:
Code:
passwd
GRUB users will follow basically the same steps, except that the GRUB boot loader doesn't have a default boot prompt, but you can choose "e'' when the menu displays to edit the boot parameters. Just select the kernel line for the kernel you want to boot. Go to the end of that line and type "single" as a separate word, then press ENTER to exit the edit mode. Once back at the GRUB screen, press "b" to boot into single user mode.
