Of course, there is probably a solution to use Discourse’s API between two separates instances. But this isn’t my main concern today.
And I don’t want to multiply droplets, each one has a substantionnal monthly cost.
This tutorial looks to be a good beginning, but there are some big lacks at several steps. How to edit app.yml, how to change listening port on Apache… It is really too synthetic : How to set up Discourse on a server with existing Apache sites
Any ideas ? Someone knows a more detailled tutorial ?
