快速入門：使用 Azure 應用程式閘道引導網路流量 - ARM 範本

發行項
06/30/2024

在此快速入門中，您將使用 Azure Resource Manager 範本 (ARM 範本) 建立 Azure 應用程式閘道。然後您會測試應用程式閘道，以確保其運作正常。此範例會使用標準 v2 SKU。

Azure Resource Manager 範本是一個 JavaScript 物件標記法 (JSON) 檔案，會定義專案的基礎結構和設定。範本使用宣告式語法。您可以描述預期的部署，而不需要撰寫程式設計命令順序來建立部署。

您也可以使用 Azure 入口網站、Azure PowerShell 或 Azure CLI 來完成本快速入門。

如果您的環境符合必要條件，而且您很熟悉 ARM 範本，請選取 [部署至 Azure] 按鈕。範本會在 Azure 入口網站中開啟。

注意

應用程式閘道前端現在可支援雙堆疊 IP 位址 (預覽版)。您現在可以建立最多四個前端 IP 位址，包括兩個 IPv4 位址 (公用和私人) 與兩個 IPv6 位址 (公用和私人)。

必要條件

具有有效訂用帳戶的 Azure 帳戶。免費建立帳戶。

為了簡單起見，此範本會建立簡單的設定，包括公用前端 IP、在此應用程式閘道上裝載單一網站的基本接聽程式、基本的要求路由規則，以及後端集區中的兩部虛擬機器。

注意

應用程式閘道前端現在可支援雙堆疊 IP 位址 (公開預覽)。您現在可以建立最多四個前端 IP 位址，包括兩個 IPv4 位址 (公用和私人) 與兩個 IPv6 位址 (公用和私人)。

提示

您可以修改 resource\applicationGateWay\properties\sku 底下的 Name 和 Tier 參數值，以使用不同的 SKU。例如： Basic 。如需部署自訂範本的相關資訊，請參閱建立和部署 ARM 樣本。

範本中定義了多個 Azure 資源：

Microsoft.Network/applicationgateways
Microsoft.Network/publicIPAddresses：一個用於應用程式閘道，兩個用於虛擬機器。
Microsoft.Network/networkSecurityGroups
Microsoft.Network/virtualNetworks
Microsoft.Compute/virtualMachines：兩個虛擬機器
Microsoft.Network/networkInterfaces：兩個用於虛擬機器
Microsoft.Compute/virtualMachine/extensions：可設定 IIS 和網頁

部署範本

將 ARM 範本部署到 Azure：

選取 [部署至 Azure] 以登入 Azure 並開啟範本。此範本會在執行 IIS 的後端集區中建立應用程式閘道、網路基礎結構和兩個虛擬機器。
選取或建立資源群組，輸入虛擬機器系統管理員的使用者名稱和密碼。
選取 [檢閱 + 建立]，然後選取 [建立]。

部署可能需要 20 分鐘或更久的時間才能完成。

驗證部署

雖然不需要 IIS 即可建立應用程式閘道，但仍會加以安裝以確認 Azure 是否已成功建立應用程式閘道。使用 IIS 測試應用程式閘道：

在 [概觀] 頁面上尋找應用程式閘道的公用 IP 位址。或者，您可以選取 [所有資源]，並在搜尋方塊中輸入 myAGPublicIPAddress，然後在搜尋結果中加以選取。 Azure 會在 [概觀] 頁面上顯示公用 IP 位址。
將公用 IP 位址複製並貼到您瀏覽器的網址列，以瀏覽該 IP 位址。
檢查回應。有效的回應會確認應用程式閘道已成功建立，並可與後端順利連線。

多次重新整理瀏覽器後，您應該會看到 myVM1 和 myVM2 的連線。

清除資源

當您不再需要先前為應用程式閘道建立的資源時，請刪除資源群組。這會移除應用程式閘道和所有相關資源。

呼叫 Remove-AzResourceGroup Cmdlet 以刪除資源群組：

Remove-AzResourceGroup -Name <your resource group name>

下一步

使用 Azure CLI 以應用程式閘道管理網路流量
