Question

我正在尝试按照this tutorial将我的应用部署到Elastic Beanstalk。

如果我使用splite3，该应用可行，但我无法将该应用连接到RDS。

我在Gemfile中添加了group :production do gem 'mysql2' end，并将此代码添加到config/database.yml。

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'] %>

我在Elastic Beanstalk console中添加了RDS。

但production.log显示错误，表示数据库连接失败。

eb status就是这样。

URL     : myAppURL
Status      : Ready
Health      : Green

RDS Database: AWSEBRDSDatabase | myDatabaseURL:port

可能我会错过一些非常基本的东西。我该怎么做才能解决这个问题？

如果您的数据库未命名为ebdb，您可以在YAML文件中对您的数据库名称进行硬编码：

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