Getting Rails to work with Apache

I'm trying to get Rails to work with Apache. To my supreme frustration, many of the instructions I've found for doing this are wildly divergent from one another. I tried following a few of them with no success.

I'm on Ubuntu 10.10, Rails 3.0.3 and Apache 2.2.16. I've already installed passenger. I don't really know what to do next.

Can anyone help me out, or at least give me a link to a decent, up-to-date set of instructions?

This RailsCast should make it a breeze.

You can try phusion_passenger. I had success with that.

Simple version sudo apt-get install libapache2-mod-passenger. More options on the official installation guide

Edit acc. to comment about wrong installation line.

Slicehost has some lovely simple guides for setting things up.
