使用 設定 Amazon Neptune 的先決條件 AWS CloudFormation

使用 AWS CloudFormation 範本建立 Amazon Neptune 叢集之前，您需要具備下列項目：

建立 Amazon EC2 Key Pair，以用於使用 啟動 Neptune 叢集 AWS CloudFormation

若要使用 AWS CloudFormation 範本啟動 Neptune 資料庫叢集，您必須在建立 AWS CloudFormation 堆疊的區域中有可用的 Amazon EC2key對 （及其相關聯的PEM檔案）。

如果您需要建立金鑰對，請參閱 Amazon EC2使用者指南中的使用 Amazon 建立金鑰對EC2，或參閱 Amazon EC2使用者指南中的使用 Amazon 建立金鑰對EC2以取得指示。

新增IAM政策以授予使用 AWS CloudFormation 範本所需的許可

首先，您需要設定具有使用 Neptune 所需許可IAM的使用者，如 中所述建立具有 Neptune 許可的 IAM 使用者。

然後，您需要將 AWS 受管政策 AWSCloudFormationReadOnlyAccess新增至該使用者。

最後，您需要建立下列客戶受管政策，並將其新增至該使用者：
