You could perhaps start all 4 servers at the same time but not start the applications automatically or perhaps only the database server. The script that starts the database could have a ssh command to the application server to start the application start script. This script in turn could start the two webserver applications.

Alternatively you could start all servers at the same time and put a wait loop at the beginning of the application start script on the application server that keeps checking if the database is availably. Likewise the webserver start scripts could check if the application is available.

The second option is probably the most trouble-free.
