rails + apache2 + fcgi: Default Rails application fails with "ActionController::RoutingError (no route found to match "/" with {:method=>:get})"

[Matej Kenda]

Binary package hint: libfcgi-ruby1.8

I was setting up the environment for developing Ruby on Rails applications.

The howtos recommend setting apache2 server with fcgi to improve the performance of RoR applications.

I followed the instructions from various places. All of the instructions on the net are similar to each other. I was not able to find the reason for the behaviour that is happening on my computer.

The overview of my setup is logged in https://wiki.ubuntu.com/MatejKenda/RubyOnRails.

I have installed everything that is required to run RoR applications via Apache2 + fcgi using apt.

After creating an empty rails application the default rails page displays if the fcgi is disabled. As soon as I enable the fcgi, the page displays only:

ActionController::RoutingError
no route found to match "/" with {:method=>:get}

The development.log contains the following log:

ActionController::RoutingError (no route found to match "/" with {:method=>:get}):

Output of ruby -d dispatch.fcgi contains statements of various missing files. Many of those files are installed (e.g. html/tokenizer), some are not.

Solved the problem by myself (it was not a bug at all). RewriteRule in .htaccess for fcgi was specified twice by mistake.
