Question

我有Power Shell脚本用于发布/更新用于运行Windows服务的新dll：

Import-Module WebAdministration

function Main(
[string] $siteName = $(Throw "Value cannot be null: siteName"),
[string] $sitePath = $(Throw "Value cannot be null: sitePath"),
[string] $servicePath = $(Throw "Value cannot be null: sitePath"),
[string] $serviceName = $(Throw "Value cannot be null: sitePath"),
[string] $buildConfiguration = $(Throw "Value cannot be null: sitePath"))
{
...

   $serviceBinPath = Join-Path $serviceBinPath $buildConfiguration
   Write-Host "Directory of Windows Service : $($serviceBinPath )`r`n"

   StopWindowsService $serviceName
   RemoveFiles $servicePath 
   CopyFiles $serviceBinPath $servicePath
   StartWindowsService $serviceName
}

function RemoveFiles(
    [string] $path = $(Throw "Value cannot be null: sitePath"))
{
    If (Test-Path $path)
    {
        Write-Host "Removing folder ($path)...`r`n"
        Remove-Item -Recurse -Force "$($path)*"
        Write-Host "Successfully removed website folder ($path)...`r`n"        
    }
}

function CopyFiles(
    [string] $sourcePath = $(Throw "Value cannot be null: sitePath"),
    [string] $destinationPath = $(Throw "Value cannot be null: sitePath"))
{
    If ((Test-Path $sourcePath) -and (Test-Path $destinationPath))
    {
        Write-Host "Copy files from ($sourcePath) to folder ($destinationPath)...`r`n"
        Copy-Item "$($sourcePath)\*" $destinationPath -Recurse -Force
        Write-Host "Successfully copied files from ($sourcePath).`r`n"
    }
}
function StopWindowsService(
    [string] $serviceName = $(Throw "Value cannot be null: siteName"))
{
    $serviceBefore = Get-Service $serviceName
    Write-Host "($serviceName) is now ($serviceBefore.status)...`r`n"

    Write-Host "Stopping Windows Service ($serviceName)...`r`n"
    Stop-Service $serviceName
    Write-Host "Successfully stopped Windows Service ($serviceName)...`r`n"

    $serviceAfter = Get-Service $serviceName
    Write-Host "($serviceName) is now ($($serviceAfter.status))...`r`n"
}

function StartWindowsService(
    [string] $serviceName = $(Throw "Value cannot be null: siteName"))
{
    $serviceBefore = Get-Service $serviceName
    Write-Host "($serviceName) is now ($serviceBefore.status)...`r`n"

    Write-Host "Starting Windows Service ($serviceName)...`r`n"
    Start-Service $serviceName
    Write-Host "Successfully started Windows Service ($serviceName)...`r`n"

    $serviceAfter = Get-Service $serviceName
    Write-Host "($serviceName) is now ($($serviceAfter.status))...`r`n"
}

一切正常，包括开始/停止/复制新的Windows服务Dll。但是当我在停止服务后尝试删除旧文件时，所有文件都被锁定，我收到错误：

Remove-Item : Cannot remove item ...\WindowsService\bin\Autofac.dll: Access to the path '...WindowsService\bin\Autofac.dll' is denied.

适用于所有dll文件。

可能需要卸载/安装服务而不是停止/运行？有什么想法吗？

Answer 1

应该停止服务。请检查以下内容：

您正在使用直接修补文件
运行脚本的应用程序或控制台在正确使用的用户下运行。
检查dlls文件夹的安全性。检查运行的应用程序的用户是否已被删除以删除指定文件夹中的文件

Answer 2

我找到了解决方案。第一件事：我在安装Windows服务处于停止状态后运行此脚本并且dll已经在文件夹中。并且第一次运行没有产生任何错误。第二次运行后，我得到了错误。当我在停止服务之后添加等待并且在删除旧的dll之前，一切都很顺利：

StopWindowsService $serviceName Start-Sleep -s 5 RemoveFiles $servicePath CopyFiles $serviceBinPath $servicePath StartWindowsService $serviceName

我认为这是因为停止服务后文件还没有立即解锁。

非常感谢。抱歉英文不好
