Hello World works on Mongrel but not in Passenger (Error 500), and nothing in the logs?

I’m sure this is something common I’m missing.

I have installed Rails on Ubuntu using the helpful information at
Getting Started with Rails — Ruby on Rails Guides and
RubyOnRails - Community Help Wiki

I’m just trying to get Hello World working before moving on to other
things. I have deleted the public/index.html (which displays fine with
Apache) and done the following:
script/generate controller home index
edit config/routes.rb and add the line map.root :controller => “home”
above the default routes

Pretty simple… so I got the Passenger error at first because root
owned config/environment.rb so it is now owned by www-data.

Now, I get Error 500 no matter what I do.

Fire up Mongrel and go to http://blah.mydomain.com:3000/ and it works
perfectly. Go to http://blah.mydomain.com/ and, Error 500 “We’re
sorry, but something went wrong.”

I hope this is something simple with the Apache config I’m simply
missing. I presume since the error shows up at all that my Passenger
config is at least correct in part.

Anyone?
Thanks,

I was suffering the same thing so:

I did this:

first in httpd.conf file, after:
 LoadModule passenger_module /opt/ruby-enterprise/lib/ruby/gems/

1.8/gems/passenger-2.1.2/ext/apache2/mod_passenger.so
PassengerRoot /opt/ruby-enterprise/lib/ruby/gems/1.8/gems/
passenger-2.1.2
PassengerRuby /opt/ruby-enterprise/bin/ruby

 RailsSpawnMethod conservative  #This I wrote it, just because the

user guide says that is necesary to do it, when works well in mongrel
not in Passenger.

Next inside apache2/conf/extra/httpd_vhosts.conf

<VirtualHost *:80>
ServerName www.sitename.com.mx #Domain name to
public
DocumentRoot “/usr/local/apache2/htdocs/sitename/public” #the
place where where app is in filesystem --erase this comment because
apache give an error.
RailsEnv development #Say to
pasenger that our app is in development.

 </VirtualHost>

It could be necesary check the path to ruby binary files ...

I hope this help.

I’ve been trying to figure out this problem for a while and stumbled
onto this forum entry. RailsEnv worked for me.

Thanks!!

Just have to say thank you for this post.
I have Ubuntu 12.04 LTS and have been trying to learn ruby on rails and
this has been something I am stuck on now for 2 days. :slight_smile: RAILS_ENV
helped, but did not solve it for me yet.

It is no good replying to a three year old thread saying that you have
the problem too. Start a new thread and describe the problem you are
seeing.
