Hello -
First, try using the ip address of the machine that is running the mySQL server as your Host on meteobridge. and if that does not work change the user from "Larry" to Meteobridge. Also if I recall my setup (on Linux) you will need to create and grant permission to user Meteobridge on your mySQL db.
Personally, I would use phpmyadmin to make changes, etc to your databases instead of the terminal.
