我正在尝试使用 aws terraform rds 模块来启动 aurora serverless mysql 5.7 版本，但在创建数据库实例时出现以下错误，指向不正确的 DBEngine。

  name        = "test-aurora-cluster-parameter-group"
  family      = "aurora-mysql5.7"
}

根据 AWS Docs，允许的家庭组是“aurora-mysql5.7”，engine_version 是“5.7.12”。https://docs.aws.amazon.com/AmazonRDS/latest/AuroraUserGuide/AuroraMySQL.Updates .serverless_2_07_01.html

尝试使用 EngineVersion：“5.7.mysql_aurora.2.08.2”和 EngineVersion 5.7.12。

【解决方案1】：

我认为这是因为拼写错误：

engine                  = "aurora-msql"

列出了可用的引擎here。因此应该有：

engine                  = "aurora-mysql"

请注意，可能还有其他不明显的错误。但是您的InvalidParameterValue: Invalid DB engine 问题很可能是拼写错误造成的。
