Setting 'root' Password for Centos.
Today my friend was having an issue where he was not able to set 'root' password.
As the default installation had a default account without "sudo" privilege.
To set the "root" password for Cent OS Follow below steps.
1. In the grub boot menu prompt - enter "e" (for edit) to edit boot parameters.
2. Select menu this will bring up 3 or more based on the installation type. root, kernel, initrd
5. Now at the boot menu enter "b" for boot
6. This will bring the system up in single user mode.
7. Enter "passwd root" >> Change your root password.
Enjoy!!
