使用PowerShell更改Azure VM的密码

燃烧器B

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：

你调用的对象是空的。

当我console.log的值$Credential.UserName和$Credential.GetNetworkCredential().Password得到我输入的用户名和密码的值时。

我在这里想念什么？

我从未用过Set-AzureVMAccessExtension，但是我用过等效的Az PowerShell Set-AzVMAccessExtension。它需要您-Credential $Credential而不是-UserName和通过-Password。

您可以尝试使用我之前制作的此脚本来重置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://docs.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://docs.microsoft.com/en-us/powershell/module/microsoft.powershell.core/about/about_pipelines?view=powershell-7
$vm | Restart-AzVM

我发现在重新启动VM之前不会发生密码更新，因此Restart-VM是必需的。
