快速入門：在 Azure Stack Hub 中使用 PowerShell 建立 Linux VM

您可以使用 Azure Stack Hub PowerShell 建立 Ubuntu Server 20.04 LTS 虛擬機 (VM) 。 在本文中，您將建立和使用虛擬機器。 本文也會說明如何：

• 使用遠端用戶端連線至 VM。
• 安裝 NGINX Web 伺服器，並且檢視預設首頁。
• 清除未使用的資源。

必要條件

• Azure Stack Hub Marketplace 中的 Linux 映像。 Azure Stack Hub Marketplace 預設沒有 Linux 映像。 讓 Azure Stack Hub 操作員提供您需要的 Ubuntu Server 20.04 LTS 映像。 操作員可以使用將 Marketplace 項目從 Azure 下載到 Azure Stack Hub 中的指示。

• Azure Stack Hub 需要特定版本的 Azure CLI，才能建立和管理其資源。

  • 如果您尚未針對 Azure Stack Hub 設定 PowerShell，請參閱安裝適用於 Azure Stack Hub 的 PowerShell。
  • 設定好 Azure Stack Hub PowerShell 後，您將會連線到 Azure Stack Hub 環境。 如需指示，請參閱以使用者的身分使用 PowerShell 連線到 Azure Stack Hub。

• 名稱為 id_rsa.pub 的公開安全殼層 (SSH) 金鑰應儲存在 Windows 使用者設定檔的 .ssh 目錄中。 如需建立 SSH 金鑰的詳細資訊，請參閱搭配 Azure Stack Hub 使用 SSH 金鑰組。

建立資源群組

資源群組是您可以在其中部署和管理 Azure Stack Hub 資源的邏輯容器。 若要建立資源群組，請執行下列程式碼區塊：

注意

我們已為下列程式碼範例中的所有變數指派值。 不過，您可以指派自己的值。

# Create variables to store the location and resource group names.
$location = "local"
$ResourceGroupName = "myResourceGroup"

New-AzResourceGroup `
  -Name $ResourceGroupName `
  -Location $location

建立儲存體資源

建立要用於儲存開機診斷輸出的儲存體帳戶。

# Create variables to store the storage account name and the storage account SKU information
$StorageAccountName = "mystorageaccount"
$SkuName = "Standard_LRS"

  -Location $location `
  -ResourceGroupName $ResourceGroupName `
  -Type $SkuName `
  -Name $StorageAccountName

建立網路安全性群組和網路安全性群組規則

網路安全性群組可使用輸入和輸出規則來保護 VM。 建立連接埠 3389 的輸入規則以允許傳入的遠端桌面連線，並建立連接埠 80 的輸入規則以允許傳入的網路流量。

連接至 VM

部署 VM 之後，請設定 VM 的 SSH 連線。 若要取得 VM 的公用 IP 位址，請使用 Get-AzPublicIpAddress 命令：

Az 模組

Get-AzPublicIpAddress -ResourceGroupName myResourceGroup | Select IpAddress

AzureRM 模組

Get-AzureRMPublicIpAddress -ResourceGroupName myResourceGroup | Select IpAddress

從已安裝 SSH 的用戶端系統，使用下列命令連線至 VM。 如果您正在使用 Windows，可以使用 PuTTY 來建立連線。

ssh <Public IP Address>

出現提示時，請以 azureuser 登入。 如果您在建立 SSH 金鑰時使用複雜密碼，您必須提供複雜密碼。

安裝 NGINX 網頁伺服器

若要更新套件資源及安裝最新的 NGINX 套件，請執行下列指令碼：

#!/bin/bash

# update package source
apt-get -y update

# install NGINX
apt-get -y install nginx

檢視 NGINX 歡迎使用頁面

在已於 VM 上安裝 NGINX Web 伺服器並開啟連接埠 80 的情況下，您可以使用 VM 的公用 IP 位址存取 Web 伺服器。 開啟網頁瀏覽器，然後前往 http://<public IP address>。

清除資源

您可以使用 Remove-AzResourceGroup 命令清除不再需要的資源。 若要刪除資源群組和其所有資源，請執行下列命令︰

Az 模組

Remove-AzResourceGroup -Name myResourceGroup

AzureRM 模組

Remove-AzureRMResourceGroup -Name myResourceGroup

在本快速入門中，您已部署基本的 Linux 伺服器 VM。 若要深入了解 Azure Stack Hub VM，請移至 Azure Stack Hub 中 VM 的考量。
