从 CustomScriptExtension 调用时，Chocolatey 在 Azure 中安装 sql-server-express 失败

The system cannot find the file specified我正在尝试启动一个新的 Azure VM，因此正在安装 Chocolatey 并使用它来安装 sql-server-express 包。不幸的是，尽管包已下载成功，但我在 Chocolatey 日志中收到错误。

我怎样才能解决这个问题？

答案1

该错误似乎与 Azure 启动 CustomScriptExtensions 的帐户有关。

我设法使用 Powershell 以管理员用户身份运行安装来解决此问题：

Enable-WSManCredSSP -Role Server -Force
Enable-WSManCredSSP -Role Client -DelegateComputer * -Force
New-Item -Path HKLM:\SOFTWARE\Policies\Microsoft\Windows\CredentialsDelegation -Name AllowFreshCredentialsWhenNTLMOnly -Force
New-ItemProperty -Path HKLM:\SOFTWARE\Policies\Microsoft\Windows\CredentialsDelegation\AllowFreshCredentialsWhenNTLMOnly -Name 1 -Value * -PropertyType String
Set-Item -Path "WSMan:\localhost\Service\Auth\CredSSP" -Value $true
$securePassword = ConvertTo-SecureString 'passwordgoeshere' -AsPlainText -Force
$credential = New-Object System.Management.Automation.PSCredential 'hostname\adminuser', $securePassword
Invoke-Command -Authentication CredSSP -ScriptBlock {choco install sql-server-express} -ComputerName hostname -Credential $credential

请注意，您必须提供主机名和用户名作为凭证（即hostname\adminuser），否则此命令将无法从 CustomScriptExtension 运行。

您还需要使用 CredSSP，否则 SQL 安装将失败并出现以下错误：
