Installing a cluster with 3 servers

[CedricD]

Hi!

I'm new to ISPConfig (I used Kloxo before) and I'm doing some of the tutorials now.
ISPConfig 3 on Debian 6 x86

I've done this one:
http://www.howtoforge.com/installing...th-ispconfig-3

No problem, everything works. Very good tutorial.

But what I want to do is this with 3 servers (not with 2 like in the tutorial).
I've tried it but it doesn't work.

What has to be changed to let it work?
MySQL Master - Master - Master?
Or MySQL Master - Master - Slave?
Replication with Unison to all 3 servers?

Replication works between server 1 & server 2. I said in ISPConfig that server 3 is a mirror from server 1 but nothing gets mirrored. No sites, no clients, no DNS templates etc.
I also don't see server 1 & server 2 when I login into my server 3 ISPConfig.
I see server 3 when logging in into ispconfig on server 1/2.

Anybody that can tell the steps how to make it work?
I'm just a newby but the tutorials are very clear. I want to have it explained like in the tutorials with the correct commands. Not like do this and change that etc.

btw: English is not my native language, sorry for the mistakes.

Thanks in advance!
