Hi For testing reasons I've set up 3 Virtual Boxes running Ubuntu-Server an prepared them with the necessary steps out of http://www.howtoforge.com/perfect-server-ubuntu-9.04-ispconfig-3 Box 1: - MySQL Server - ISPConfig Interface Box 2: - Mailserver Box 3: - Apache (for the hosting) Everything works fine for now! But a few questions are still bugging me... Why do I need a MySQL-Server running on every Box? The Installation (only) creates an "ISPConfig DB" there and inputs just the server running on! Also it moves the interface to /var/www even if I choose not to do !! If I choose to join an existing setup for Box2 and 3 it creates the Servers in the DB on Box1 and in the DB on themselves... Why that???
