I finally completed my own app, so the only work left is deploying the app.

I'm using Ubuntu 10.04 and apache2(installed by apt-get), so I'm trying to deploy through passenger.

I installed passenger gem like this:

sudo gem install passenger
rvmsudo passenger-install-apache2-module

and I configured apache settings as what the installation message says.

I added below lines in the middle of /etc/apache2/apache2.conf file.

LoadModule passenger_module /home/admin/.rvm/gems/ruby-1.9.3-p194/gems/passenger-3.0.17/ext/apache2/mod_passenger.so
PassengerRoot /home/admin/.rvm/gems/ruby-1.9.3-p194/gems/passenger-3.0.17
PassengerRuby /home/admin/.rvm/wrappers/ruby-1.9.3-p194/ruby

and, I appended below lines in /etc/apache2/sites-available/default file.

<VirtualHost *:80>
  ServerName localhost
  # !!! Be sure to point DocumentRoot to 'public'!
  DocumentRoot /home/admin/homepage/public
  <Directory /home/admin/homepage/public>
     # This relaxes Apache security settings.
     AllowOverride all
     # MultiViews must be turned off.
     Options -MultiViews
  </Directory>

But when I restart the apache service and hit the address, 500 error occurs.

At first, it was same 500 error but the 500 error page is from apache's, but when I reinstalled the libapache2-module-passenger, the 500 error page is changed to that from rails'.

Because of rails' 500 error page(which is located at public/500.html), I think passenger module is properly connected with apache.

What should I do to fix this problem?

Do I need to configure something inside my app before deployment?
