Amazon RDS 模板代码段

Amazon RDS 数据库实例资源

此示例显示了使用托管主用户密码的 Amazon RDS 数据库实例资源。有关更多信息，请参阅《Amazon RDS 用户指南》中的使用 Amazon Secrets Manager 管理密码和《Aurora 用户指南》中的使用 Amazon Secrets Manager 管理密码。由于没有指定可选的 EngineVersion 属性，因此会将默认引擎版本用于此数据库实例。有关默认引擎版本和其他默认设置的详细信息，请参阅 CreateDBInstance。DBSecurityGroups 属性向名为 MyDbSecurityByEC2SecurityGroup 和 MyDbSecurityByCIDRIPGroup 的 AWS::RDS::DBSecurityGroup 资源授予网络入口权限。有关详细信息，请参阅AWS::RDS::DBInstance。数据库实例资源还有一个设置为 Snapshot 的 DeletionPolicy 属性。如果设置了 Snapshot DeletionPolicy，则在堆栈删除期间，Amazon CloudFormation 会首先拍摄该数据库实例的快照，然后再将其删除。

Amazon RDS Oracle Database 数据库实例资源

此示例创建了使用托管主用户密码的 Oracle Database 数据库实例资源。有关更多信息，请参阅《Amazon RDS 用户指南》中的使用 Amazon Secrets Manager 管理密码。此示例将 Engine 指定为 oracle-ee 并使用“自带许可”许可模式。有关 Oracle Database 数据库实例设置的详细信息，请参阅 CreateDBInstance。DBSecurityGroups 属性授权对名为 MyDbSecurityByEC2SecurityGroup 和 MyDbSecurityByCIDRIPGroup 的 AWS::RDS::DBSecurityGroup 资源的网络访问。有关详细信息，请参阅AWS::RDS::DBInstance。数据库实例资源还有一个设置为 Snapshot 的 DeletionPolicy 属性。如果设置了 Snapshot DeletionPolicy，则在堆栈删除期间，Amazon CloudFormation 会首先拍摄该数据库实例的快照，然后再将其删除。

适用于 CIDR 范围的 Amazon RDS DBSecurityGroup 资源

此示例说明一个 Amazon RDS DBSecurityGroup 资源，该资源具有以 ddd.ddd.ddd.ddd/dd 格式指定的 CIDR 范围的入口授权。有关详细信息，请参阅 AWS::RDS::DBSecurityGroup 和 Ingress。

带 Amazon EC2 安全组的 Amazon RDS DBSecurityGroup

此示例展示的 AWS::RDS::DBSecurityGroup 资源具有 MyEc2SecurityGroup 所引用 Amazon EC2 安全组中的入口授权。

要执行此操作，您需要定义一个 EC2 安全组，然后在 DBSecurityGroup 中使用 Ref 内置函数引用该 EC2 安全组。
