Re: [phusion-passenger] Rails3 application, but wrongly detected as a Rails1 or Rails2 application

[Hongli Lai]

Do you have a 'RailsBaseURI /' directive in your Apache config? That
forces Phusion Passenger to detect the app as a Rails 1 or 2 app, so
please remove it to allow proper autodetection.

Well in that case: does your application root contain a 'config.ru'?
Phusion Passenger autodetects the application type as follows:

1. If config.ru exists: it is a Rack or Rails 3 app
2. If not, and config/environment.rb exists: it is a Rails 1 or Rails 2 app
3. If not, there is no app and the request should be handled by the web server

Hongli - In my case, I have config.ru at the root of the app AND config/environment.rb exists. 

Is this why I'm running into this issue? Any work around?

Had the same problem, found a ticket in bug tracker with working workaround at:

https://code.google.com/p/phusion-passenger/issues/detail?can=2&start=0&num=100&q=wrongly%20detected&colspec=ID%20Type%20Status%20Priority%20Milestone%20Stars%20Summary&groupby=&sort=&id=882

change RailsBaseURI to RackBaseURI in your apache2 config 

[Najam Farooq Alvi]

1. If config.ru exists: it is a Rack or Rails 3 app

Thanks  Hongli Li, 

I spent few hours to find a solution for redmine showing index of problem and only found it over here. Config.ru was missing in my base redmine folder.
