sql-server - 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”

问题描述

我正在尝试将 SQL Server 2017 无人值守安装到 Windows 10 Azure 虚拟机中，通过巧克力在远程 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，日志文件只告诉我这个异常已经被抛出：

我已经检查过，启动它的用户具有管理员权限。

但这只发生在我之前没有使用远程桌面连接到机器的情况下，如果我连接然后启动该过程它将顺利进行。

问题是这必须是一个自动化的过程，所以我无法打开与创建的机器的远程桌面连接。

有人知道发生了什么吗？

谢谢。

解决方案

发放赏金后不久，我自己就想出了这一点。CredSSP 可以做到这一点，但它不像单线那么简单。基本上，这是“双跳”问题，如果您没有通过身份验证，您将遇到此错误。

要启用 CredSSP，您需要在服务器上运行它（您尝试安装 SQL Server 的远程主机：

Enable-WSManCredSSP -Role Server -Force

您还需要在客户端（委托给服务器的机器）上启用 CredSSP：

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

此外，您需要允许客户端上的凭据委派，这可以在 PowerShell 中使用此脚本自动完成：

$allowed = @("WSMAN/$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++
}

如果您还没有，请确保两台机器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 Session 对我不起作用，我不得不发送Invoke-Commandwith -Authentication CredSSP：

$cred = New-Object System.Management.Automation.PSCredential ($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
