How to reset root password on CentOS 6
When we forgot password root on Centos, we can reset that password easily. We have to use single mode to do that.

Step 2: Choose kernel line and type “e”
Step 3: In kernel configuration , we have 2 methods to change to single mode. 1 we can use number “1”, 2 we can use character “S”. Enter after done.
Step 4: Choose kernel which we just made change and type “b” to boot
