How to protects Linux and Unix machines from accidental shutdowns/reboots with molly-guard

How to protects Linux and Unix machines from accidental shutdowns/reboots with molly-guard
Oops! I did it again. I thought I was logged into my home server. Turns out I rebooted the db server. Another my not so favorite is typing “shutdown -h 0” into the wrong terminal. I know a few people who have admitted to doing that here.

My anger that can't be contained
Is there any end to the madness? Do I need to suffer from accidentally random reboots and shutdowns? After all, it is human nature to make mistakes, but one should not keep on making the same mistakes again and again.
