Azure自定义脚本扩展程序不断重新启动

在Windows VM上使用Azure自定义脚本扩展时遇到一些问题。我创建了一个安装特定业务应用程序的脚本。为了实现这一点，脚本会调用其他几个脚本，并且需要在两个脚本之间重新启动。

脚本的设计使得它可以“捡起它停在的地方”。通过检查某些文件是否存在或是否存在注册表项。重启部分很好，但是，我注意到脚本处理程序设置了几个注册表项以跟踪其状态

HKEY_LOCAL_MACHINE \ SOFTWARE \ Microsoft \ Windows Azure \ ScriptHandler

我看到一个名为＆＃34; MreSeqNumStarted＆＃34;的注册表值，我认为这是脚本处理程序如何跟踪它执行的脚本。当前只有一个脚本由扩展名触发，并且此值设置为0。

我所看到的是，在脚本完成后重新启动计算机时，脚本会再次触发。每次重新启动虚拟机时都会发生这种情况。我相信脚本扩展不会将脚本标记为＆＃34;已完成＆＃34;，而且我有点不知道为什么。脚本的基本（已消毒）流程如下：

trap {$_.Exception.Message; Get-PSCallstack;continue}

if(Test-Path C:\ScriptLog.txt)
{
    Add-Content "C:\ScriptLog.txt" "`nScript Previously Run, Prior log exists."
} else {
    Write-Host "Begin Script" | Out-File "C:\ScriptLog.txt"
}

#$storagePath = [uri]::EscapeDataString($storagePath)
#Create Directory Structure and download scripts/files
if(Test-Path C:\PreparePlatform\) {
    Add-Content "C:\ScriptLog.txt" "`nFiles Already Downloaded... Continuing"
} else {
    New-Item -ItemType Directory -Force -Path C:\SoftwareName\PreparePlatform\
    (New-Object Net.WebClient).DownloadFile('SAS-URL-GOES-HERE','C:\SoftwareName\PreparePlatform\PreparePlatform.zip');(new-object -com shell.application).namespace('C:\SoftwareName\PreparePlatform').CopyHere((new-object -com shell.application).namespace('C:\SoftwareName\PreparePlatform\PreparePlatform.zip').Items(),16)
    (New-Object Net.WebClient).DownloadFile('SAS-URL-GOES-HERE','C:\SoftwareName\SOMEZIP.zip');(new-object -com shell.application).namespace('C:\SoftwareName').CopyHere((new-object -com shell.application).namespace('C:\SoftwareName\SOMEZIP.zip').Items(),16)
    Add-Content "C:\ScriptLog.txt" "`nExtracted Install Media"
}

if(Test-Path C:\SoftwareName\preparedone.txt)   {
    Add-Content "C:\ScriptLog.txt" "`nPreparePlatform already completed... Continuing"
} else {

    Write-Host "PreparePlatform Complete" | Out-File "C:\SoftwareName\preparedone.txt"
}
if(Test-Path C:\SoftwareName\UpdatePlatform.txt)    {
    Add-Content "C:\ScriptLog.txt" "`nUpdatePlatform already completed... Continuing"
} else {
    Add-Content "C:\ScriptLog.txt" "`nBegin Update-Platform"
    Invoke-Expression "Set-Location C:\SoftwareName\PreparePlatform\; C:\SoftwareName\PreparePlatform\Update-WindowsPlatform.ps1"
    Write-Host "UpdatePlatform Complete" | Out-File "C:\SoftwareName\UpdatePlatform.txt"
}

if(Test-Path C:\SoftwareName\Rebooted.txt)  {
    Add-Content "C:\ScriptLog.txt" "`nReboot already completed... Continuing"
} else {
    Write-Host "Rebooting" | Out-File "C:\SoftwareName\Rebooted.txt"
    Restart-Computer -Force
    Restart-Computer -Force
    Start-Sleep 3600 #Make sure nothing else executes
}


#  TODO:  Make more robust for potentially more nodes... need to delay 1 hour for each node
If($env:computername -eq 'pvm-SoftwareName-1') { Write-Output "Second Node, waiting 1 hour"; Add-Content "C:\ScriptLog.txt" "`nNot First Node, waiting 1 hour" ;Start-Sleep -Seconds 3600 }

        }

}
catch

    $_.Exception.Message;Get-PSCallStack
    if (-not (Get-Service -Name 'SoftwareName Server').Status -eq 'Running') 
    {throw "Service unavailable"}

}
Write-Output "Install Finished."

}
try

    {throw "Install Finalize Failed"}
}

#Kill the script
Add-Content "C:\ScriptLog.txt" "`nScript Completed"
Exit

以下是C：\ ScriptLog.txt

的预期输出 
Begin Scheduled Job Regstration
Extracted Install Media
Begin PreparePlatform
Completed PreparePlatform
Begin Update-Platform
Script Previously Run, Prior log exists.
Files Already Downloaded... Continuing
PreparePlatform already completed... Continuing
UpdatePlatform already completed... Continuing
Reboot already completed... Continuing
Prepare SOFTWARENAME Installers
Prepare SOFTWARENAME Installers complete
C:\SOFTWARENAME\Script\Install-K2BP.ps1 -parameterValues $values
C:\SOFTWARENAME\Script\Install-K2SF.ps1 -parameterValues $values
C:\SOFTWARENAME\Script\Install-K2SP.ps1 -parameterValues $values
C:\SOFTWARENAME\Script\Install-K2MG.ps1 -parameterValues $values
C:\SOFTWARENAME\Script\Install-Finalize.ps1 -parameterValues $values
Script Completed

重启后，相同的日志文件：

Begin Scheduled Job Regstration
Extracted Install Media
Begin PreparePlatform
Completed PreparePlatform
Begin Update-Platform
Script Previously Run, Prior log exists.
Files Already Downloaded... Continuing
PreparePlatform already completed... Continuing
UpdatePlatform already completed... Continuing

Prepare SOFTWARENAME Installers complete
C:\SOFTWARENAME\Script\Install-SOFTWARENAMEBP.ps1 -neededParameters $values
C:\SOFTWARENAME\Script\Install-SOFTWARENAMESF.ps1 -neededParameters $values
C:\SOFTWARENAME\Script\Install-SOFTWARENAMESP.ps1 -neededParameters $values
C:\SOFTWARENAME\Script\Install-SOFTWARENAMEMG.ps1 -neededParameters $values
C:\SOFTWARENAME\Script\Install-Finalize.ps1 -neededParameters $values

PreparePlatform already completed... Continuing
UpdatePlatform already completed... Continuing
Reboot already completed... Continuing
Prepare SOFTWARENAME Installers
Prepare SOFTWARENAME Installers complete

Edit1：我已经注释掉了对外部脚本的所有调用。此时脚本仅将输出写入文件effectivley并捕获任何异常。每次重新启动VM时，脚本都会继续重新启动。
