Question

我是Amazon RDS的新手，并按照this教程设置了数据库实例。接下来，我按照this教程从eclipse连接到数据库实例。我可以在Amazon RDS选项卡下的AWS Explorer中找到数据库实例。另外，我可以通过MySQL Workbench连接到数据库实例。当我尝试通过eclipse连接时，我收到此错误：

“无法连接到数据库。请确保您的密码正确无误，并确保您可以通过网络和可能连接的任何防火墙访问您的数据库。”

错误日志包含以下内容：

Error-Could not connect to Amazon RDS DB: testconnect - US East (Virginia).

Warning-Error creating JDBC Connection connection to Amazon RDS DB: testconnect - US East (Virginia). (Error: Unknown database 'null')

Warning-Error creating SQL Model Connection connection to Amazon RDS DB: testconnect - US East (Virginia). (Error: Unknown database 'null')

错误日志已扩展到控制台：

检查您是否可以从eclipse主机访问RDS。你可以简单地使用telnet。大部分时间我们在私人区域创建RDS。如果它在私有区域中，您可以使用VPN连接进行连接，并使用适当的安全组配置。
