What process is resurrecting mysqld?

Question

I'm following this guide to reset my mysql root password (I'm on ubuntu). When I kill the mysqld process, it immediately gets resurrected. The parent process ID is 1.

How can I find what keeps resurrecting mysqld?

$ ps -ef | grep mysql
mysql    30136     1  0 07:16 ?        00:00:00 /usr/sbin/mysqld
root     30295 30274  0 07:18 pts/0    00:00:00 grep --color=auto mysql
$ kill -9 30136
$ ps -ef | grep mysql
mysql    30302     1  2 07:18 ?        00:00:00 /usr/sbin/mysqld
root     30404 30274  0 07:18 pts/0    00:00:00 grep --color=auto mysql
$

Ubuntu uses upstart:

You already found your answer - but for the sake of clarity.

You should try not to kill daemons or processes which are working okay - and you should certainly try and avoid kill -9. There is usually always a way to request daemons to stop gracefully which allow them to tidy up.

Kill on it's own (e.g. kill 30136 in your case) can sometimes correctly stop a process, but it depends on the process in question and what signals it is looking for.
