Started to read the Manual for ISPConfig 3.1, and it looks like I've to restart with installation?! Used the perfect Server for Debian 8.4, which didn't seems to includes the changes for Debian 8.7.1, the version I used for to install. Upfront I asked for the Scripts for 8.7.1 and got answered that I've to use 8.4 (because I need Apache2), and done that. Reading now, seems I miss quite a bit?! But I run out of time now and have 1 week left for to get things working! The installation done went mainly OK, except some very few problems and I didn't installed Metronome at all. Now in Chapter 3.2.xxx is the 'talking' from installing Multi Server's for Web, Mail, Db and so on! Do I need to do that? I was thinking that I simply need to install a Single Server, with all different modules on it. What do I need to install extra? Please explain in details. I simply was thinking that I could now start to configure the installed ISPConfig on Debian 8.7.1! Where do I start with the configure for a Single Server Setup? Thanks for any advice.
