如何使用 Azure Resource Manager 範本建立 Linux 虛擬機器

適用於:✔️ Linux VM ✔️ 彈性擴展集

了解如何使用 Azure Resource Manager 範本和 Azure CLI,從 Azure Cloud Shell 建立 Linux 虛擬機器 (VM)。 若要建立 Windows 虛擬機器,請參閱從 Resource Manager 範本建立 Windows 虛擬機器

替代方法是從 Azure 入口網站部署範本。 若要在入口網站中開啟範本,請選取 [部署至 Azure] 按鈕。

將 Resource Manager 範本部署至 Azure 的按鈕。

範本概觀

Azure Resource Manager 範本是 JSON 檔案,檔案中定義您的 Azure 解決方案的基礎結構和組態。 透過範本,您可以在整個生命週期中重複部署方案,並確信您的資源會以一致的狀態部署。 若要深入了解範本格式和其建構方式,請參閱快速入門:使用 Azure 入口網站建立及部署 Azure Resource Manager 範本。 若要檢視資源類型的 JSON 語法,請參閱在 Azure Resource Manager 範本中定義資源

快速入門範本

注意

所提供的範本會依預設建立 Azure 第 2 代 VM

注意

使用快速入門範本時,預設只會啟用 SSH 驗證。 出現提示時,提供您自己 SSH 公開金鑰的值,例如 ~/.ssh/id_rsa.pub 的內容。

如果您沒有 SSH 金鑰組,請參閱為 Azure 中的 Linux VM 建立和使用 SSH 金鑰組

您也可以下載或建立範本,並用 --template-file 參數指定本機路徑。

使用 Azure CLI 建立快速入門範本 VM

取得或建立快速入門範本之後,請使用 Azure CLI 建立 VM。

下列命令會要求使用者的數個輸入片段。 其中包括:

  • 資源群組名稱 (resourceGroupName)
  • 裝載 VM 的 Azure 資料中心位置 (location)
  • VM 相關資源的名稱(projectName)
  • 系統管理員使用者的使用者名稱 (username)
  • 用來存取 VM 終端機的公用 SSH 金鑰 (key)

建立 Azure 虛擬機器需要資源群組。 快速入門範本的其中一個流程包括建立資源群組。

若要執行 CLI 指令碼,請按一下 [開啟 Cloudshell]。 存取 Azure Cloudshell 之後,按一下 [複製] 來複製命令,然後以滑鼠右鍵按一下殼層,選取 [貼上]

echo "Enter the Resource Group name:" &&
read resourceGroupName &&
echo "Enter the location (i.e. centralus):" &&
read location &&
echo "Enter the project name (used for generating resource names):" &&
read projectName &&
echo "Enter the administrator username:" &&
read username &&
echo "Enter the SSH public key:" &&
read key &&
az group create --name $resourceGroupName --location "$location" &&
az deployment group create --resource-group $resourceGroupName --template-uri https://raw.githubusercontent.com/azure/azure-quickstart-templates/master/quickstarts/microsoft.compute/vm-sshkey/azuredeploy.json --parameters projectName=$projectName adminUsername=$username adminPublicKey="$key" &&
az vm show --resource-group $resourceGroupName --name "$projectName-vm" --show-details --query publicIps --output tsv

最後一行命令會顯示新建立 VM 的公用 IP 位址。 您需要公用 IP 位址以連線到虛擬機器。

連線至虛擬機器

之後您便可以如常透過 SSH 連線至您的 VM。 提供您自己的公用 IP 位址 (透過先前命令取得):

ssh <adminUsername>@<ipAddress>

其他範本

在此範例中,您建立基本的 Linux VM。 如需其他 Resource Manager 範本,包含應用程式架構,或建立更複雜的環境,請瀏覽 Azure 快速入門範本
