用于设置 NeptuneAmazon CloudFormation 的先决条件

在使用Amazon CloudFormation模板创建 Amazon Neptune 集群之前，您需要具备以下条件：

使用创建 Amazon EC2 密钥对，用于启动 Neptune 集群Amazon CloudFormation

要使用Amazon CloudFormation模板启动 Neptune 数据库集群，您必须在创建Amazon CloudFormation堆栈的区域中有 Amazon EC2KEY 对（及其关联的 PEM 文件）可用。

如果您需要创建key pair，请参阅 Linux 实例的 Amazon EC2 用户指南中的使用 Amazon EC2 用户指南中的使用Amazon EC2 创建密钥对。

添加 IAM 策略以授予使用Amazon CloudFormation模板所需的权限

首先，您需要设置一个 IAM 用户，该用户拥有使用 Neptune 所需的权限，如中所述创建具有 Neptune 权限的 IAM 用户。

然后，您需要向该用户添加Amazon托管策略。AWSCloudFormationReadOnlyAccess

最后，您需要创建以下客户管理策略并将其添加到该用户：
