I have tried to add a second server to an existing and working server, the problems I face is this: Due to that I do not find a guide describing multi server setup when using nginx i tried to modify the guide slightly and ended up missing to install postfix. both server will have everything installed accept that the second server will not have a ispconfig web-interface. When installing ISPconfig on the second server I succesfully added it to master server but everything halted when postfix was missing. I installed required software to my debian server and restarted the install process again but this time everything halted due to that: " - database already have some fields already" When going to my ispconfig panel on the master server I can see the the newly added server but I am not sure it was added correctly. What I need to know is how do I revert the previous setup and start all over without the second server removing the fields added on the master database?
