# Amazon Cognito 用户群体选项

以下各节涉及 CloudFormation 快速创建链接或快速 URLs创建。快速创建 URL 会将您带到**创建堆栈向导**，您可以在其中提供快速创建堆栈模板输入并部署堆栈。*有关 CloudFormation 快速创建堆栈的更多信息，请参阅《用户指南》中的[为堆栈创建快速创建链接](https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/cfn-console-create-stacks-quick-create-links.html)。AWS CloudFormation *

要维护可用于多个用户 AWS ParallelCluster 界面 (PCUI) 实例的 Amazon Cognito 用户池，请考虑以下选项：
+ 使用链接到基于嵌套堆栈创建的 Amazon Cognito 用户池的现有 PCUI 实例。 CloudFormation 这是您使用快速创建链接部署 PCUI 并将所有 Amazon Cognito 参数留空时创建的内容。
+ 首先，部署一个独立的 Amazon Cognito 用户池。然后，部署一个与您刚刚部署的独立 Amazon Cognito 用户池关联的新 PCUI 实例。这样，您可以将 Amazon Cognito 部署与 PCUI 部署分开。请注意，非嵌套的 PCUI CloudFormation 堆栈更易于更新。

# 将现有 Amazon Cognito 用户池与新 PCUI 实例结合使用
<a name="install-pcui-existing-cognito-v3"></a>

完成以下步骤将现有 Amazon Cognito 用户池与新 PCUI 实例结合使用

**将现有 Amazon Cognito 用户池与新 PCUI 实例结合使用**

1. 在**CloudFormation 控制台**中，选择包含要用于多个 PCUI 实例的 Amazon Cognito 用户池的 PCUI 堆栈。

1. 导航到创建 Amazon Cognito 用户群体的嵌套堆栈。

1. 选择**输出**选项卡。

1. 复制以下参数的值：
   + `UserPoolId`
   + `UserPoolAuthDomain`
   + `SNSRole`

1. 使用快速创建链接并用您复制的输出填充所有 `External PCUI Amazon Cognito` 参数，部署一个新 PCUI 实例。这可防止新 PCUI 堆栈创建新用户池，并将其链接到从嵌套堆栈创建的现有 Amazon Cognito 用户池。您可以随后部署具有相同参数值的新 PCUI 实例，并可以将它们链接到 Amazon Cognito 用户池。

**创建独立的 Amazon Cognito 用户池**

1. 从以下列表中选择一个标有相同 AWS 区域 标签的快速创建链接，即可启动仅限 Amazon Cognito 的堆栈：

1. 堆栈创建完成后，选择**输出**选项卡并复制以下参数的值：
   + `UserPoolId`
   + `UserPoolAuthDomain`
   + `SNSRole`

1. 通过选择 PCUI 快速启动链接并用您复制的值填充所有 `External PCUI Amazon Cognito` 参数，部署一个新 PCUI 实例。新的 PCUI 实例链接到独立的 Amazon Cognito 用户池，不会创建嵌套堆栈或新的用户池。您可以随后部署具有相同参数值的新 PCUI 实例，并可以将它们链接到独立的 Amazon Cognito 用户池。
