Root Password Expired

less than 1 minute read


I ran into an issue while trying to lock down my testlab Centos 7 VM where a bash script I ran made the root password expire! Here is how to resolve:

To Resolve:

  1. Reboot the machine.

  2. Follow steps in my post about getting in to pre-boot

    chroot /sysroot
    # Set password to never expire (probably not best practice, but we change ours every 180 days anyways)
    chage -I -1 -m 0 -M 99999 -E -1 root
    # Go ahead and change it for now
    passwd root
    # Update SELinux Info
    touch /.autorelabel
    reboot -f
  3. Now log back in locally and see if it works!
