In March, I’ve set up a Redmine application with the Ruby webserver Webrick. Since then, I’ve migrated to Apache, and then the question was: Which Ruby bridge module to use? It’s not that the choice is large, you have mod_fastcgi, mod_fcgid and mod_rails a.k.a. Passenger. I’ve tried the three of them, and only one was a success.
As for the last post about Redmine, I’ve compiled everything (Apache included) in a custom location and I start the server from there (without root rights).
