Recover a forgotten root password on Redhat Linux
Boot up/ restart your server. As soon as the grub menu loads, hit e to edit.
Look for this line, rhgb quiet LANG-en_US.UTF-8 Add rd.break at the end of that line. Then hit ctrl + x to boot into single user mode
- 
    mount -o remount,rw /sysroot 
- 
    chroot /sysroot 
Now you can change the password by typing passwd root and creating new password
- 
    passwd root–change the password 
- 
    exit 
Finally, relable all files when system boots up, this is important so as to maintain due to SElinux contexts
- touch / .autorelabel#if this is not done passwd change will not be successful ~~~
