azure - 使用 PowerShell 更改 Azure VM 的密码

Question

我尝试过这种方法来更改 Azure VM 的密码:

$resgroup = "rsource1"
$vmName = "virtualmachine1"

$VM = Get-AzVM -ResourceGroupName $resgroup -Name $vmName 

$Credential = Get-Credential

$VM | Set-AzureVMAccessExtension    –UserName $Credential.UserName `
                                    –Password $Credential.GetNetworkCredential().Password

$VM | Update-AzVM

但我不断收到此错误:

Object reference not set to an instance of an object.

当我 console.log $Credential.UserName 和 $Credential.GetNetworkCredential().Password 的值时，我得到了以下值我输入的用户名和密码。

我在这里缺少什么？

我从未使用过 Set-AzureVMAccessExtension，但我使用过 Az PowerShell 等效项 Set-AzVMAccessExtension 。它需要您传递 -Credential $Credential 而不是 -UserName 和 -Password。

您可以尝试我不久前制作的这个脚本来重置 Azure VM 的密码:

# Replace these values with your own
$resourceGroupName = "Servers-RG"
$vmName = "server1"

# Get the VM into an object
$vm = Get-AzVM -ResourceGroupName $resourceGroupName -Name $vmName 

# Store credentials you want to change
$credential = Get-Credential -Message "Enter your username and password for $vmName"

# Store parameters in a hashtable for splatting
# Have a look at https://learn.microsoft.com/en-us/powershell/module/microsoft.powershell.core/about/about_splatting?view=powershell-7
$extensionParams = @{
    'VMName' = $vmName
    'Credential' = $credential
    'ResourceGroupName' = $resourceGroupName
    'Name' = 'AdminPasswordReset'
    'Location' = $vm.Location
}

# Pass splatted parameters and update password
Set-AzVMAccessExtension @extensionParams

# Restart VM
# Don't need to pass any switches since they are inferred ByPropertyName
# Have a look at https://learn.microsoft.com/en-us/powershell/module/microsoft.powershell.core/about/about_pipelines?view=powershell-7
$vm | Restart-AzVM

我发现密码更新只有在重新启动虚拟机后才会发生，因此需要 Restart-VM。
