Question

我有一个RDS实例，我可以通过命令提示符连接如下：

mysql --host=rds-instance-name.ciplxctxy9hy.us-west-1.rds.amazonaws.com --user=username --password=password database

这很有效。当我尝试eb deploy到Amazon Web Services弹性beanstalk实例时，我收到此错误：

INFO: Deploying new version to instance(s).
ERROR: [Instance: i-08388abd] Command failed on instance. Return code: 1 Output:
 (TRUNCATED)...ash -c 'leader_only bundle exec rake db:migrate' webapp
rake aborted!
Mysql2::Error: Can't connect to MySQL server on 'rds-instance-name.ciplxctxy9hy
.us-west-1.rds.amazonaws.com' (4)

我的ruby实例中的database.yml文件包含以下内容：

production:
  adapter: mysql2
  encoding: utf8
  database: database
  username: username
  password: password
  host: rds-instance-name.ciplxctxy9hy.us-west-1.rds.amazonaws.com

当我在本地启动ruby服务器时，我没有错误：

C:/Development/Ruby/environment-name/bin/rails server -b 0.0.0.0 -p 3000 -e production

我需要更改为rds实例或database.yml以允许我部署？

我会查看RDS实例上的安全组，并确保它允许来自EC2实例的传入连接。

Elastic Beanstalk无法连接到RDS
