I am running Ruby on Rails 3.0.9 in production mode on a remote VPS

  • 0

I am running Ruby on Rails 3.0.9 in production mode on a remote VPS machine running Ubuntu 10.04 LTS (in development mode I use RoR on a MAC OS Snow Leopard) and I would like to know how to manage the following scenario.

I use Apache2 and Phusion Passenger and I have set Virtual Host as-like this:

<VirtualHost *:80>
  ServerName project_name.com
  DocumentRoot /srv/www/project_name.com/public

  <Directory /srv/www/project_name.com/public>
    AllowOverride all
    Options -MultiViews
  </Directory>
</VirtualHost>

More, I use the Paperclip gem and, as a lot of people on the web using it in production mode, I get the following error on handling (image) files:

Errno::EACCES (Permission denied - /srv/www/project_name.com/public/images/001):
...

I heard that a solution in order to avoid those kind of errors is to set properly folder permissions (manually! – I don’t know if it is possible to automate that “setting” process… BTW: is it possible?) but I think there is a better way to solve that. If so, what can\should I do?

    @M. Cypher is close, although the biggest issue I see is that you’re allowing users to upload arbitrary files and then marking them all executable. This is a disaster looking for a place to happen.

    find /srv/www/project_name.com/public -type d -exec chmod 755 {}\;
find /srv/www/project_name.com/public -type f -exec chmod 644 {}\;

    This will set executable on directories (necessary) but not on files.
