尝试在无人参与的情况下安装SQL Server 2017时出现错误:生成XML文档时出错

Question

我正在尝试通过巧克力将SQL Server 2017无人参与地安装到Windows 10 Azure虚拟机中，在远程powershell会话上使用以下命令：

choco install sql-server-express -ia ""/IACCEPTSQLSERVERLICENSETERMS /FEATURES=SQLEngine /Q /ACTION=install /INSTANCEID=[INSTANCE_NAME] /INSTANCENAME=SQLCHEMETER /FILESTREAMLEVEL=1 /SECURITYMODE=SQL /SAPWD=[SA_PASSWORD] /UPDATEENABLED=FALSE"" -o -y"

但是安装失败了，日志文件只告诉我抛出了这个异常：

我已经检查过了，启动它的用户拥有管理员权限。

但这只会在我之前没有连接到具有远程桌面的计算机时发生，如果我连接然后启动该进程，它将顺利进行。

问题是，这必须是一个自动化的过程，所以我不能打开与创建的机器的远程桌面连接。

有人知道这是怎么回事吗？

谢谢。

Answer 1

在悬赏后不久我就想通了。CredSSP做到了这一点，但它不像一行程序那么简单。基本上，这是“双跳”问题，如果你没有通过身份验证，你就会遇到这个错误。

要启用CredSSP，您需要在服务器(尝试在其上安装SQL server的远程主机：

Enable-WSManCredSSP -Role Server -Force

您还需要在客户机上启用CredSSP，即委托给服务器的机器：

Enable-WSManCredSSP -Role client -DelegateComputer $nameOrIp -Force

此外，您还需要允许客户端上的凭据委派，这可以在PowerShell中使用以下脚本自动完成：

$allowed = @("WSMAN/$nameOrIp")
$key = 'hklm:\SOFTWARE\Policies\Microsoft\Windows\CredentialsDelegation'
if (!(Test-Path $key)) {
    md $key
}
New-ItemProperty -Path $key -Name AllowFreshCredentials -Value 1 -PropertyType Dword -Force            
$key = Join-Path $key 'AllowFreshCredentials'
if (!(Test-Path $key)) {
    md $key
}
$i = 1
$allowed |% {
    New-ItemProperty -Path $key -Name $i -Value $_ -PropertyType String -Force
    $i++
}

如果尚未设置，请确保两台计算机都已将彼此设置为受信任的主机：

$curList = (Get-Item WSMan:\localhost\Client\TrustedHosts).value
$exists = $curList -match $nameOrIp
if ($exists -eq $false) {
  "Adding IP to trusted hosts..."
  Set-Item WSMan:\localhost\Client\TrustedHosts -Value "$curList, $nameOrIp" -Force
}

最后，使用现有的会话对我不起作用，我必须使用-Authentication CredSSP发送Invoke-Command

$cred = New-Object System.Management.Automation.PSCredential ($adminName, $secureWindowsPassword)
Invoke-Command -Computername $nameOrIp -Authentication CredSSP -Credential $cred -ScriptBlock {
    Param($sqlPass)
    Start-Process -FilePath C:\temp\SQLEXPR_x64_ENU.exe -Args "/ConfigurationFile=C:\temp\MSSQL.ini /SAPWD='$sqlPass' /Q /HIDECONSOLE /UpdateEnabled=FALSE" -Verb RunAs -Wait 4>&1
} -ArgumentList $sqlPass

在启动SQL Server安装程序之前，在powershell会话中运行以下命令：

Enable-WSManCredSSP -Role "Server"
