使用设置亚马逊 Neptune 的先决条件 AWS CloudFormation

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

• 亚马逊EC2密钥对。

• 使用所需的权限 AWS CloudFormation。

使用创建用于启动 Neptune 集群的 Amazon EC2 密钥对 AWS CloudFormation

要使用 AWS CloudFormation 模板启动 Neptune 数据库集群，您必须在创建堆栈的区域中提供 Amazon EC2key 配对（及其关联PEM文件）。 AWS CloudFormation

如果您需要创建密钥对，请参阅亚马逊用户指南EC2中的使用亚马逊创建密钥对，或亚马逊EC2用户指南EC2中的使用亚马逊创建密钥对以获取说明。EC2

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

首先，您需要为IAM用户设置使用 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 AWS 托管策略。AWSCloudFormationReadOnlyAccess

最后，您需要创建以下客户管理型策略并将其添加到该用户：

注意

以下权限仅在删除堆栈时需要：iam:DeleteRole、iam:RemoveRoleFromInstanceProfile、iam:DeleteRolePolicy、iam:DeleteInstanceProfile 和 ec2:DeleteVpcEndpoints。

另请注意，ec2:*Vpc 授予 ec2:DeleteVpc 权限。
