您请求的引擎模式 serverless 目前在 5.7 (2.07.1) 中不可用

如何解决您请求的引擎模式 serverless 目前在 5.7 (2.07.1) 中不可用

尝试用 MysqL 2.07.1 少创建一个 RDS aurora 服务器 并收到错误“您请求的无服务器引擎模式当前不可用。（服务：AmazonRDS；状态代码：400；错误代码：InvalidParameterValue；请求 ID：xxxx；代理：null）”

任何建议都会对我有很大帮助

这是示例代码

              },"DBClusterIdentifier" : "my-serverless-cluster","Engine" : "aurora","EngineVersion" : "2.07.1","EngineMode" : "serverless","ScalingConfiguration" : {

              }
          }
      }
  }
}

解决方法

您正在尝试使用 Aurora MySQL 2.07.1（即 MySQL 5.7 版本[+] a link）创建 RDS aurora serverless。 查看上面的代码和模板参数，我可以看到您拥有的“Engine”参数是“aurora”，对于 MySQL 5.7 版本 [+] (https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-resource-rds-dbcluster.html#cfn-rds-dbcluster-engine)，它应该是“aurora-mysql”。
