快速入门：使用 Azure 应用程序网关定向 Web 流量 - ARM 模板

项目
06/04/2024

在本快速入门中，使用 Azure 资源管理器模板（ARM 模板）创建 Azure 应用程序网关。然后，我们对应用程序网关进行测试，确保其正常运行。此示例中使用了标准 v2 SKU。

Azure 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。你可以在不编写用于创建部署的编程命令序列的情况下，描述预期部署。

还可以使用 Azure 门户、Azure PowerShell 或 Azure CLI 完成本快速入门。

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。

注意

应用程序网关前端现在支持双堆栈 IP 地址（预览版）。现在，可以创建最多四个前端 IP 地址：两个 IPv4 地址（公共和专用）和两个 IPv6 地址（公共和专用）。

先决条件

具有活动订阅的 Azure 帐户。免费创建帐户。

查看模板

为简单起见，此模板创建了一项简单设置，其中包含一个公共的前端 IP、一个在应用程序网关上托管单个站点的基本侦听器、一项基本的请求路由规则，以及两个位于后端池的虚拟机。

应用程序网关前端现在支持双堆栈 IP 地址（公共预览版）。现在，可以创建最多四个前端 IP 地址：两个 IPv4 地址（公共和专用）和两个 IPv6 地址（公共和专用）。

提示

可以在 resource\applicationGateWay\properties\sku 下修改 Name 和 Tier 参数的值以使用不同的 SKU。例如：Basic。有关部署自定义模板的信息，请参阅“创建和部署 ARM 模板”。

模板中定义了多个 Azure 资源：

Microsoft.Network/applicationgateways
Microsoft.Network/publicIPAddresses：一个用于应用程序网关，两个用于虚拟机。
Microsoft.Network/networkSecurityGroups
Microsoft.Network/virtualNetworks
Microsoft.Compute/virtualMachines：两个虚拟机
Microsoft.Network/networkInterfaces：两个用于虚拟机
Microsoft.Compute/virtualMachine/extensions：用于配置 IIS 和网页

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。该模板在运行 IIS 的后端池中创建应用程序网关、网络基础结构和两个虚拟机。
选择或创建资源组，键入虚拟机管理员用户名和密码。
选择“查看 + 创建”，然后选择“创建”。

部署可能需要 20 分钟或更长时间才能完成。

验证部署

虽然不需 IIS 即可创建应用程序网关，但安装它可以验证 Azure 是否已成功创建应用程序网关。使用 IIS 测试应用程序网关：

在“概览”页上找到应用程序网关的公共 IP 地址。另外，你也可选择“所有资源”，在搜索框中输入 myAGPublicIPAddress，然后在搜索结果中将其选中。 Azure 会在“概览”页上显示公共 IP 地址。
复制公共 IP 地址，然后将其粘贴到浏览器的地址栏中，以便浏览该 IP 地址。
检查响应。有效响应验证应用程序网关是否已成功创建，以及是否能够成功连接后端。

多次刷新浏览器就会看到与 myVM1 和 myVM2 的连接。

清理资源

如果不再需要通过应用程序网关创建的资源，请删除资源组。这样会删除应用程序网关和所有相关的资源。

若要删除资源组，请调用 Remove-AzResourceGroup cmdlet：

Remove-AzResourceGroup -Name <your resource group name>

后续步骤

通过 Azure CLI 使用应用程序网关管理 Web 流量
