Unable to rake db:migrate in production

Question

I have created a user and granted it full access to the production database:

mysql> show grants for 'myuser'@'localhost';
+-----------------------------------------------------------------------------------------------------------------+
| Grants for myuser@localhost                                                                                   |
+-----------------------------------------------------------------------------------------------------------------+
| GRANT USAGE ON *.* TO 'myuser'@'localhost' IDENTIFIED BY PASSWORD '*xxxxxxxx' |
| GRANT ALL PRIVILEGES ON `myapp_production`.* TO 'myuser'@'localhost'                                       |
+-----------------------------------------------------------------------------------------------------------------+
2 rows in set (0.00 sec)

But when I rake db:migrate , I get:

** [out :: mydomain.com] Mysql2::Error: Access denied for user 'myuser'@'localhost' (using password: NO)

If I enter the root credentials into database.yml then it seems to work but I cannot use root user in production because of internal policies.

Answer 1

The MySQL message has an important pointer:

Access denied for user 'myuser'@'localhost' (using password: NO)

It tells you, that the client doesn't use a password. Apparently, you don't have the password configured correctly in the database.yml for your production db. Once you configure the correct password there, it'll work.

Answer 2

rails by default uses production environment so if you change db to some other environment .

i had the same error this worked

 bundle exec rake db:migrate RAILS_ENV=production
