If you're worried about ssh brute force or just don't like all the noise in your logs, moving the port tends to drop off about 95% of them. In addition, running iptables tarpit rules (or your OS equivalent) tends to kill the rest fairly quickly.
One easy way to manage it is make a folder for each hostname, and add things like mysql root password, ssh port, public IP, pivate IP as different entries relating to the all aspects of managing the host.
