Server setup option for rails with different ruby and rails versions

Question

I'm in the process of setting up my VPS (linode) to host a few rails websites. What are some good options for setting up one server that will be hosting rails websites that are on different versions of rails and ruby. For example

foo.com - ruby 1.9.2, rails 3.0
bar.com - ruby 1.9.3, rails 3.2.3

I've seen only one blog post (using passenger) regarding a setup like this but I'm interested in finding out what some other solutions look like. Or if this is a BAD idea and I should be using different VPS's for each I'd like to know othat too.

例如，您可以在每个应用程序中使用独立的Passenger或Unicorn实例，并通过Apache或Nginx对其进行反向代理，以便它将在默认端口80上响应
