我为此向 AWS 创建了一个支持请求,他们的答案如下。我会试一试。
嗨阿利斯泰尔,
感谢您联系 AWS 高级支持。今天很高兴为您提供帮助。
我了解到您想从 QuickSight 连接到您的 Prod RDS 数据库,但您收到错误消息:“未验证”。您还想知道是否有解决方法可以看到您的 RDS 实例无法公开访问。
Amazon Web Services 提供了一项名为 CloudFormation 的服务,该服务有助于自动化某些流程。此服务将允许您的 RDS 实例通过自定义 NAT 实例连接到 QuickSight。因此,您不必将数据库放在公共子网中。附件是 CloudFormation 模板 (NAT_RDS_Provisioning.template),在启动 CloudFormation 堆栈 [1] 后,将创建一个实例和一个安全组,然后输入所需的变量。然后,这将允许从您定义的源端口上的源地址访问 EC2 实例的端点,这将允许 QuickSight 访问您的 RDS 实例服务器,而无需公开您的 RDS 实例。
要启动此 CloudFormation 堆栈,请参阅以下步骤……请记住,您创建此堆栈的区域必须与您的数据库所在的区域相同。
1. From your AWS console navigate to " CloudFormation "
2. Click " create stack ", you will then be asked to Select Template, you will then select " Design template".
3. Next to Parameters - click " Mappings ", at the bottom of that page you will see: Components and Template.
4. Select " Template " and copy and paste the provided script in there. (see attached: NAT_RDS_Provisioning.template)(Please use case link below signature)
5. In the top right hand corner you will see a refresh button, click to refresh.
6. On the top left there is a square with a tick inside (clicking this validates the template).
7. Once validated - click the little cloud with the arrow in it , this will create the stack.
8. You will be taken back to the select template page, click "next" in the bottom right corner.
9. Under Specify Details, name your stack and then complete all Parameters, info on parameters provided below:
9.1 Stack name (Example: NAT-RDS-QuickSight)
9.2 DestinationAddress - Add your RDS instance Endpoint here. (That way when a fail-over occurs the endpoint should be updated in 60 seconds maximum).
9.3 DestinationPort - The service remote destination port:
9.4 InstanceType - The EC2 instance class. (The size of the NAT instance will depend on the amount of data you want to pull into QuickSight)
9.5 KeyName - Name of an existing EC2 KeyPair to enable SSH access to the instance:
9.6 SourceAddress - The source range you want to allow access from: example 0.0.0.0/0.
9.7 SourcePort - The port the service must listen on:
9.8 Subnet - a Public Subnet that is in the same VPC as your RDS instance:
10. Click " Next "
11. On the Options page - complete the desired fields and click " Next " (Optional)
12. Review all information - (Confirm the details for your NAT EC2 instance)
13. Under template you will see "Estimate cost - click on cost to give you an idea of the monthly estimate to have this service running)
14. Then select " Create " in the bottom right hand corner.
15. On the main CloudFormation Page, click "refresh" You will the notice the status of your Stack being created.
16. If you navigate to your EC2 console you will notice your NAT instance running / creating.
请确保 NAT 实例可以访问您的 RDS 实例,这包括安全组设置。这应该通过在 RDS 实例数据库的安全组中包含 NAT 实例的 IP 地址来完成。
然后,您应该能够按照设置访问 EC2 IP 地址和端口,这会将流量转发到您的数据库。
在创建上述内容时,您会看到所涉及的估算成本,但是我在下面添加了两个链接以获取更多信息以及成本计算器。
成本将与 EC2 实例相同,这将启动 AWS Linux 最新标准 AMI,吞吐量将由实例类 [2] 和 [3] 确定:

我希望以上信息和解决方案对您有所帮助。
如果您在上述任何方面遇到任何困难,或者如果您不确定任何事情,请随时与我联系,我将非常乐意为您提供帮助。
