Booting into single user mode and changing root password Centos / Redhat 7
since among other things this process is also now different in redhat 7 / CentOS 7
here is how you do it in redhat 7
During boot, press "e" at the grub loader.
Scroll down using the arrow keys to the line starting with "linux". It would look like this.
Remove the following from that line. "rhgb" and "quiet".
Add the following to the end of the line. "init=/bin/sh".
Press ctrl+x to continue the boot process.
Once the system is booted, you will be at the root user in single user mode. But this is in a read only file system.
You need to mount the / filesystem.
mount -o remount, rw /
Test that you can write to /, following command should work without error.
Now change your password for root
Touch the following file to make sure things are ok on SELinux, this is a fix file process.
Finally start the normal boot process.
