Not a valid directory (didn't found the answer on the net)

Question

Here is my question i have made a standard rail and redmine installation under ubuntu 12. And i have this error : The directory "/var/www" does not appear to be a valid Ruby on Rails application root.

It seems to be a common error but no solution on the net : http://www.google.fr/search?q=The+directory+%22%2Fvar%2Fwww%22+does+not+appear+to+be+a+valid+Ruby+on+Rails+application+root.+&ie=utf-8&oe=utf-8&aq=t&rls=org.mozilla:fr:official&client=firefox-a

Here is my default file :

<VirtualHost *:80>

        DocumentRoot /var/www

</VirtualHost>
Include /etc/apache2/mods-available/passenger.conf

and my passenger.conf :

<IfModule mod_passenger.c>
  PassengerRoot /usr
  PassengerRuby /usr/bin/ruby
  PassengerDefaultUser www-data
</IfModule>

And i don't understand why ... Regards Bussiere

Answer 1

You should point DocumentRoot tho the public dir inside the rails app

DocumentRoot /var/www/YOUR_APP_NAME/public

[...]

<Directory /var/www/YOUR_APP_NAME/public>

Answer 2

乘客下的Rails应用程序的DocumentRoot应该是该应用程序的public目录。

Answer 3

Some installation instruction had a mistake with simlink creating. The right simlink is the following for using.

sudo ln -s /usr/share/redmine /var/www/redmine

vhost should be like this:

<VirtualHost *:80>
  ServerName redmine.yourdomain.tld  

  DocumentRoot /var/www/redmine/public  

  PassengerMaxPoolSize 4
  PassengerDefaultUser www-data
  RailsEnv production
  RailsBaseURI /  

  <Directory /var/www/redmine/public>
    Options FollowSymLinks
    AllowOverride None
    Order allow,deny
    Allow from all
  </Directory>  

  LogLevel info
  ErrorLog /var/log/apache2/redmine-error.log
  CustomLog /var/log/apache2/redmine-access.log combined
</VirtualHost>
