CentOS 7 root password reset

If we have a CentOS 7 or Red Hat Enterprise Linux (RHEL 7) with a selinux in enforced mode, the password resetting procedure need to be modified.

  • From the Grub menu type “e” in order to edit the default menu item.
  • Find the line that starts with “linux16”. At the end of this line append the text “rd.break”
  • touch /.autorelabel
  • Type exit once
  • type reboot
