我可以通过 WindowsFeature 资源和 NET-Framework-45-Core 功能使用 PowerShell DSC 在 Windows Server 2012 R2 上安装 .NET Framework 4.5。我的问题是,如何使用 PowerShell DSC 确保已安装 .NET 4.5.2?
答案1
不确定 OP 是否仍需要这样做,但最近我遇到了完全相同的挑战,在尝试在 2012 R2 服务器上仅使用包资源时,发现安装程序本身存在许多问题。最终不得不编写脚本资源并使用 Web 安装程序,因为完整包始终无法解压,并出现非常常见的错误。
无论如何,这是我最终得到的工作脚本资源:
Configuration Net452Install
{
node "localhost"
{
LocalConfigurationManager
{
RebootNodeIfNeeded = $true
}
Script Install_Net_4.5.2
{
SetScript = {
$SourceURI = "https://download.microsoft.com/download/B/4/1/B4119C11-0423-477B-80EE-7A474314B347/NDP452-KB2901954-Web.exe"
$FileName = $SourceURI.Split('/')[-1]
$BinPath = Join-Path $env:SystemRoot -ChildPath "Temp\$FileName"
if (!(Test-Path $BinPath))
{
Invoke-Webrequest -Uri $SourceURI -OutFile $BinPath
}
write-verbose "Installing .Net 4.5.2 from $BinPath"
write-verbose "Executing $binpath /q /norestart"
Sleep 5
Start-Process -FilePath $BinPath -ArgumentList "/q /norestart" -Wait -NoNewWindow
Sleep 5
Write-Verbose "Setting DSCMachineStatus to reboot server after DSC run is completed"
$global:DSCMachineStatus = 1
}
TestScript = {
[int]$NetBuildVersion = 379893
if (Get-ItemProperty -Path 'HKLM:\SOFTWARE\Microsoft\NET Framework Setup\NDP\v4\Full' | %{$_ -match 'Release'})
{
[int]$CurrentRelease = (Get-ItemProperty -Path 'HKLM:\SOFTWARE\Microsoft\NET Framework Setup\NDP\v4\Full').Release
if ($CurrentRelease -lt $NetBuildVersion)
{
Write-Verbose "Current .Net build version is less than 4.5.2 ($CurrentRelease)"
return $false
}
else
{
Write-Verbose "Current .Net build version is the same as or higher than 4.5.2 ($CurrentRelease)"
return $true
}
}
else
{
Write-Verbose ".Net build version not recognised"
return $false
}
}
GetScript = {
if (Get-ItemProperty -Path 'HKLM:\SOFTWARE\Microsoft\NET Framework Setup\NDP\v4\Full' | %{$_ -match 'Release'})
{
$NetBuildVersion = (Get-ItemProperty -Path 'HKLM:\SOFTWARE\Microsoft\NET Framework Setup\NDP\v4\Full').Release
return $NetBuildVersion
}
else
{
Write-Verbose ".Net build version not recognised"
return ".Net 4.5.2 not found"
}
}
}
}
}
Net452Install -OutputPath $env:SystemDrive:\DSCconfig
Set-DscLocalConfigurationManager -ComputerName localhost -Path $env:SystemDrive\DSCconfig -Verbose
Start-DscConfiguration -ComputerName localhost -Path $env:SystemDrive:\DSCconfig -Verbose -Wait -Force
答案2
根据这篇 Microsoft Technet 文章,要安装的功能的名称应该是获取 WindowsFeature命令的结果。因此,如果 .NET 4.5.2 没有出现在列表中,则无法确保它已通过 DSC 安装。
姓名指示要确保添加或删除的角色或功能的名称。这与 Get-WindowsFeature cmdlet 中的 Name 属性相同,而不是角色或功能的显示名称。
因此,我猜您必须通过 DCS(4.5)安装主要版本,然后找出最佳解决方案将其更新到 4.5.2。
