Boot into root shell without prompting password
1) Reboot server
2) Next, you will see grub-boot loader screen. Select Recovery mode the version of the kernel that you wish to boot and type e for edit. Select the line that starts with kernel and type e to edit the line.
3) Go to the end of the line and type init=/bin/bash as a separate one word (press the spacebar and then type init=/bin/bash). Press enter key to exit edit mode.
init=/bin/bash
4) Back at the GRUB screen, type b to boot into single user mode. This causes the system to boot the kernel and run /bin/bash instead of its standard init. This will allow us gain root privileges (w/o password) and a root shell.
