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

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>
