Action Controller: Exception caught.

When I try to access localhost:3000, it shows ActiveRecord::NoDatabaseError. Can anybody tell me how to fix it? I have attached a screenshot of it below.



It appears that you have configured a database, but that database isn't running correctly, or doesn't have a user named "root". That name is commonly used in a default MySQL install. If you're using a different database engine, then the default user may be named differently. That's where I would start looking. The answer will be very specific to your own server.


I think you misconfigure the database.

There is no database username named root.

Please check the database.yml file.

Thank you
