What is the problem?

Sometimes you want to run  several instances of the same application on your server. How to easily do this in rails?

The solution

Rails offers us the environments, allowing to run an application under different status: development, test or production environment.  We can this by adding other environments for our needs.

We just have to create in the database.yml a specific database connection for each new environment:

prod1:

  adapter: mysql

  database: prod_one

  username: root

  password: password

and to create a specific configuration file ‘prod1.yml‘ in the directory config/environments/.

After this, you just have to generate the database schema with the following command:

rake db:migrate RAILS_ENV=prod1

And to run the server on a specified port:

./script/server -p 4000 -e prod1

Now you are able to run as instance you want of your rails app on your server.
