Reset root Password for Redhat/CentOS/Sl Linux 5.x Rumi, November 1, 2012November 1, 2012 You can log in using single-user mode and create a new root password. To enter single-user mode, reboot your computer. If you use the default boot loader, GRUB, you can enter single user mode by performing the following: 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. You are presented with a prompt that looks similar to the following: grub append> ro root=LABEL=/ Press the Spacebar once to add a blank space, then add the word single to tell GRUB to boot into single-user Linux mode. The result should look like the following: ro root=LABEL=/ single Press [Enter] and GRUB will boot single-user Linux mode. After it finishes loading, you will be presented with a shell prompt similar to the following: sh-2.05b# You can now change the root password by typing passwd root You will be asked to re-type the password for verification. Once you are finished, the password will be changed. You can then reboot by typing reboot at the prompt; then you can log in to root as you normally would.
