SSH into Azure Linux Virtual Machine using SSH public-private key pair with Putty
使用Putty採用SSH private key連線到Azure Linux Virtual Machine

1.下載private key
如果使用Azure Cloud Shell(Bash)建立的Linux VM

az vm create --resource-group myRG1 --name myVM2 --image UbuntuLTS --admin-username azureuser --generate-ssh-keys

SSH public-private key會儲存在~/.ssh/目錄下
~/.ssh/id_rsa是private key
~/.ssh/id_rsa.pub是public key

2.下載id_rsa (private key)

輸入/id_rsa，然後按下Download

3.use the PuTTYgen to convert the key from the OpenSSH format to the PuTTY format.
將private key轉換為Putty可讀取的格式

按下Load，選擇C:\Temp\Azure\id_rsa 檔案

然後按下Save private key，將檔案儲存為C:\Temp\Azure\id_rsa.ppk

4.Configure SSH Keys Authentication for PuTTY
使用Pageant設定SSH KEY授權

啟動Pagent後，在系統右下角常駐程式區，在Pageant圖示按下右鍵選擇Add Key

選擇上一個步驟所產生的 id_rsa.ppk

5.Connect to Azure Linux VM with Putty

使用Putty連線到Azure Linux VM
Host Name輸入 使用者帳號@VM的外部IP，例如 azureuser@13.67.65.46
