# 使用 CloudFormation 启动登录区的先决条件
<a name="lz-apis-cfn-setup"></a>

1. 从 AWS CLI，使用 AWS Organizations `CreateOrganization` API 创建组织并启用所有功能。

   有关更详细的说明，请参阅 [步骤 1：配置登录区](lz-api-prereques.md)。

1. 从 CloudFormation 控制台或使用 AWS CLI，部署 CloudFormation 模板，此模板在管理账户中创建以下资源：
   + 日志存档账户（有时称为“日志记录”账户） 
   + 审计账户（有时称为“安全”账户） 
   + **AWSControlTowerAdmin**、**AWSControlTowerCloudTrailRole**、**AWSControlTowerConfigAggregatorRoleForOrganizations** 和 **AWSControlTowerStackSetRole** 服务角色。

     有关 AWS Control Tower 如何使用这些角色执行登录区 API 调用的信息，请参阅 [Step 1: Configure your landing zone](lz-api-prereques.md)。
