Redmine

My webserver is not the same as my SQL server, so I configured my database.yml file as follows:

production:
  adapter: mysql
  database: redmine
  username: redmine
  password: *****
  encoding: utf8
  host: storage

Note: storage is a resolvable hostname on the webserver.

But then, when I try to load a page, I get the following error:

Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2)

Honestly, I don't know anything about Rails, so maybe it is not the right place to report such a problem. Any help would be appreciated.
