'root'@'localhost' (using password: YES)

my database.yml is show below my database is sample_app

# SQLite version 3.x
#   gem install sqlite3
#
#   Ensure the SQLite 3 gem is defined in your Gemfile
#   gem 'sqlite3'
development:
  adapter: mysql2
  database: db/development.mysql2
  pool: 5
  timeout: 5000
  database: sample_app
  username: root
  socket: /tmp/mysql.sock

# Warning: The database defined as "test" will be erased and
# re-generated from your development database when you run "rake".
# Do not set this db to the same as development or production.
test:
  adapter: mysql2
  database: db/test.mysql2
  pool: 5
  timeout: 5000
  database: sample_app
  username: root
  socket: /tmp/mysql.sock

 production:
  adapter: mysql2
  database: db/production.mysql2
  pool: 5
  timeout: 5000
  database: sample_app
  username: root
  socket: /var/run/mysqld/mysqld.sock

Answer 1

You should not be using root to connect to a db with an app. Create a new user/password with a name to recognize that it is being used for a specific app\task then use that instead of root.

add this for empty password password:

production:
  adapter: mysql2
  database: db/production.mysql2
  pool: 5
  timeout: 5000
  database: sample_app
  username: root
  password:
  socket: /var/run/mysqld/mysqld.sock

If you still get access denied, then the db is saying that the user\password is not valid
