Try: "sudo service mysqld stop" and then "sudo service mysqld start"

So the PID file is literally just a text file containing the Process ID of the running MySQL process. If you're on a Unix-like system (OS X or Linux), you can do something like this:

myprompt$ ps aux | grep mysql
...
mysql     2888  0.2  4.0 1747972 324024 ?      Sl   Mar04  12:24 /usr/sbin/mysqld --basedir=/usr --datadir=/var/lib/mysql...

ps aux is listing the running processes on your system, while the grep mysql bit filters to output to only lines containing mysql. You might see a few more lines than this, but look for/some/path/mysqlor/some/path/mysqld`. It should look something like my example. The PID is the second column.

Once you have the PID, you literally can just send a signal to shut it down:

myprompt$ kill -TERM <your-pid-goes-here>

That will send the TERM signal to MySQL which should get it shutting down.

I don't have much experience with MySQL on Windows, but this might help. You'll probably need to change the paths in their examples to point to your installation.

That said, if you have frequent problems stopping MySQL because of PID issues it's pretty likely there's some configuration issue.
