I just created a rails box in Nitrous IO. Rails boxes come predefined to use sqlite3 but I want to use mysql2. Since I can't use mysql from the box because it fires up an error that it can't connect to a socket, they can connect the box to a free database service in Heroku. I created an account in Heroku, and logged in from my box to heroku. I am having problems linking the database (cleardb) to the rails box in NitrousIO, since they only show procedure to link a postgres db.
My database.yml file has the following:
development:
adapter: mysql2
encoding: utf8
database: testdb_development
pool: 5
username: root
password:
host: localhost
