快速入门：部署具有可用性区域的 Azure 防火墙 - ARM 模板

项目
03/28/2023

在本快速入门中，使用 Azure 资源管理器模板（ARM 模板）在三个可用性区域中部署 Azure 防火墙。

资源管理器模板是定义项目基础结构和配置的 JavaScript 对象表示法 (JSON) 文件。模板使用声明性语法。在声明性语法中，你可以在不编写创建部署的编程命令序列的情况下，描述预期部署。

此模板创建带防火墙的测试网络环境。网络具有一个虚拟网络 (VNet)，其中包含三个子网：AzureFirewallSubnet、ServersSubnet 和 JumpboxSubnet。 ServersSubnet 和 JumpboxSubnet 子网均包含一个单个、双核 Windows Server 虚拟机。

防火墙在 AzureFirewallSubnet 子网中，并配置有一个应用程序规则集合，其中包含允许访问 www.microsoft.com 的单个规则。

用户定义的一个路由，它引导来自 ServersSubnet 子网的网络流量穿过应用了防火墙规则的防火墙。

有关 Azure 防火墙的详细信息，请参阅使用 Azure 门户部署和配置 Azure 防火墙。

如果你的环境满足先决条件，并且你熟悉如何使用 ARM 模板，请选择“部署到 Azure”按钮。 Azure 门户中会打开模板。

先决条件

具有活动订阅的 Azure 帐户。创建试用版订阅。

模板中定义了多个 Azure 资源：

部署模板

将 ARM 模板部署到 Azure：

选择“部署到 Azure”，登录到 Azure 并打开模板。该模板将创建 Azure 防火墙、网络基础结构和两个虚拟机。
在门户中的“创建具有区域的 Azure 防火墙的沙盒设置”页上，键入或选择以下值：
- 资源组：选择“新建”，键入资源组的名称，然后选择“确定”。
- 虚拟网络名称：键入新 VNet 的名称。
- 管理员用户名：键入管理员用户帐户的用户名。
- 管理员密码：键入管理员密码。
阅读条款和条件，选择“我同意上述条款和条件”，然后选择“购买”。部署可能需要 10 分钟或更长时间才能完成。

查看已部署的资源

浏览使用防火墙创建的资源。

若要了解模板中防火墙的 JSON 语法和属性，请参阅 Microsoft.Network/azureFirewalls。

清理资源

当不再需要这些资源时，可以通过运行 PowerShell 命令 Remove-AzResourceGroup 来删除资源组、防火墙和所有相关的资源。若要删除名为 MyResourceGroup 的资源组，请运行：

Remove-AzResourceGroup -Name MyResourceGroup
