Rails & Amazon RDS : "프로덕션 데이터베이스가 구성되어 있지 않습니다."

Question

AWS의 새로운 점이며 Beanstalk에서 내 Rails 응용 프로그램을 부팅하려고합니다. recent tutorial을 따르고 있지만 내 앱이 RDS에 연결되는 데 막혔습니다. 승객 화면이 오류와 함께 온다 : 내가 RDS 인스턴스가 구성되어 실행해야합니까

production: 
  adapter: mysql2 
  encoding: utf8 
  database: <%= ENV['RDS_DB_NAME'] %> 
  username: <%= ENV['RDS_USERNAME'] %> 
  password: <%= ENV['RDS_PASSWORD'] %> 
  host: <%= ENV['RDS_HOSTNAME'] %> 
  port: <%= ENV['RDS_PORT'] %> 

:

production database is not configured (ActiveRecord::AdapterNotSpecified) 

내 database.yml는 것 같습니다. 또한 EC2 인스턴스로 ssh'ed하고 RDS_USERNAME, RDS_HOSTNAME 등을 통해 RDS에 성공적으로 연결할 수 있는지 확인했습니다.

아마도 MySQL에서 수동으로 데이터베이스를 만들 필요가 있다고 생각했지만 MySQL 클라이언트를 사용했습니다. 그,하지만 난 여전히 같은 오류가 발생합니다.

그래서 다시 내가 수동으로 프로젝트를 체크 아웃하고 실패 어디에의 더 완전한 그림을 얻기 위해 bundle exec rake db:migrate --trace을 실행 한 EC2 인스턴스 :

** Invoke db:migrate (first_time) 
** Invoke environment (first_time) 
** Execute environment 
** Invoke db:load_config (first_time) 
** Execute db:load_config 
rake aborted!
