Forgot root Password = Please help

plumberg

Ok, so it finally happened. I have a VM which I did not access for a long time and I don't seem to recollect the root password (sorry, I am yet to advance to keys - that will be my next step).

I have access to the console and can mount a rescue disk too.

Any quick pointers to get access to my vm please?

Thanks in advance

If you have console access just put it in single usermode and reset the password.

Google example: centos 7 single user mode

Fastest way if you have access to the grub menu is to append init=/bin/sh to the linux ... line. It should pop you into a root shell where you can reset the password via passwd.

Just Google for more specifics on the init=/bin/sh option and you'll find enough to help you through.

I think this did the trick. Thank you @InceptionHosting

@InceptionHosting Turns out I had another user created which was supposed to be used for login instead of root; whose password is working already.

Guess a nice new thing learned today
