Installation Issues... (First Discourse Installation Experience)

Thank you.

I want a multisite Setup - so i need the reverse proxy thing… but for any more advanced guide i found here - i’ll need first a working base installation.

is there somewhere a more manual installation manual - or is it really needed to reduce the machine first totally to build later up… ?

Discourse should’nt be the only Software that will run on this machine… and i just want to have an idea how to keep it on his own layer - while accessing to it - over a public proxy layer…

Because thats a throw away machine anyway - i will try for sure… its the first time ever i have to do it for a web app - just because “to keep it easy”…
