如何强制停止处于“停止挂起”状态的一项或多项服务

Question

我想停止一个 Windows 服务，但它挂起或卡在Stopping 状态。我们正在使用混合操作系统，例如 Windows 2008/2012R2。

$ServerList = 'C:\Powershell\SCXAgentDSC\list.txt'  
$SCXAgents = Get-Content -Path $ServerList  

foreach ($scxagent in $SCXAgents) {
  $Hostname = $scxagent
  Write-Host $Hostname
  #Ping host
  $IP = (Test-Connection $hostname -Count 1 -ErrorAction SilentlyContinue |
        Select-Object -ExpandProperty ProtocolAddress)
  if ($IP -eq $null) {
    continue
  }
  #Get state of service 
  $servicestate = Get-Service -ComputerName $Hostname service_name -ErrorAction SilentlyContinue
  #If service is stopped or does not exist, continue otherwise set to stopped and disabled
  if ($servicestate.status -eq 'Stopped' -or $servicestate.status -eq $null) {
    continue
  } else {
    (Get-Service -ComputerName $Hostname service_name).Stop()
    Set-Service -ComputerName $Hostname -Name service_name -StartupType Disabled
    Write-Host "stopped services" -BackgroundColor yellow
    $RPMLines = Get-Service -ComputerName $Hostname service_name

    if ($RPMLines.status -match "Stopped") {
      $ServiceStatus = "STOPPED"
    } else {
      $ServiceStatus = "RUNNING"
    }
    # Port testing (22 and 1270)
    try {
      if ((New-Object System.Net.Sockets.TcpClient("$scxagent", "1270")).Connected -eq $true) {
        $AgentPortStatus = "OK"
      } else {
        $AgentPortStatus = "NOT OK"
      }
    } catch {
      $AgentPortStatus = "NOT OK"
    }
    try {
      if ((New-Object System.Net.Sockets.TcpClient("$scxagent", "22")).Connected) {
        $sshstatus = "OK"
      } else {
        $sshstatus = "NOT OK"
      }
    } catch {
      $sshstatus = "NOT OK"
    }

    Write-Output "$scxagent | SSH : $sshstatus | AgentPort : $AgentPortStatus | AgentServStatus : $ServiceStatus"
  }
}

另外，在我的代码上方，我希望将输出格式化为一行，对吗？例如：

scxagent sshstatus AgentPortStatus AgentServStatus
Server1 OK OK 已停止
Server2 不正常 不正常 正在运行
等等

最后更新：

if (-not ([Security.Principal.WindowsPrincipal][Security.Principal.WindowsIdentity]::GetCurrent()).IsInRole([Security.Principal.WindowsBuiltInRole]"Administrator")) {
  $arguments = "& '" + $myinvocation.mycommand.definition + "'"
  Start-Process powershell -Verb runAs -ArgumentList $arguments
  break
}

$ServerList = 'C:\Powershell\SCXAgentDSC\list.txt'  
$SCXAgents = Get-Content -Path $ServerList  

foreach ($scxagent in $SCXAgents) {
  $Hostname = $scxagent
  Write-Host $Hostname
  #Ping host
  $IP = (Test-Connection $hostname -Count 1 -ErrorAction SilentlyContinue |
        Select-Object -ExpandProperty ProtocolAddress)
  if ($IP -eq $null) {
    continue
  }
  #Get state of service 
  $servicestate = Get-Service -ComputerName $Hostname service_name -ErrorAction SilentlyContinue
  #If service is stopped or does not exist, continue otherwise set to stopped and disabled
  if ($servicestate.Status -eq 'Stopped' -or $servicestate.Status -eq $null) {
    continue
  } else {
    $pid = Get-WmiObject -Computer $hostname -Class Win32_Service -Filter "Name='service_name'" |
           Select-Object -Expand ProcessID

    (Get-Process -Computer $hostname -PID $pid).Kill()

    (Get-Service -ComputerName $Hostname service_name).Stop()
    Set-Service -ComputerName $Hostname -Name service_name -StartupType Disabled
    Write-Host "stopped services" -BackgroundColor yellow

    $RPMLines = Get-Service -ComputerName $Hostname service_name

    if ($RPMLines.Status -match "Stopped") {
      $ServiceStatus = "stop"
    } else {
      $ServiceStatus = "start"
    }
    # Port testing (22 and 1270)
    try {
      if ((New-Object System.Net.Sockets.TcpClient("$scxagent", "1270")).Connected -eq $true ) {
        $AgentPortStatus = "OK"
      } else {
        $AgentPortStatus = "NOT OK"
      }
    } catch {
      $AgentPortStatus = "NOT OK"
    }
    try {
      if ((New-Object System.Net.Sockets.TcpClient("$scxagent", "22")).Connected) {
        $sshstatus = "OK"
      } else {
        $sshstatus = "NOT OK"
      }
    } catch {
      $sshstatus = "NOT OK"
    }

    Write-Output "$scxagent | SSH : $sshstatus | AgentPort : $AgentPortStatus | AgentServStatus : $ServiceStatus"

    Read-Host -Prompt "Press Enter to continue"
  }
}

错误信息：

错误：无法覆盖变量 PID，因为它是只读的或常量。

如果服务在收到停止请求后挂起，那么“强制停止”的唯一方法就是终止进程，正如@autsvet 已经提到的那样。使用PID识别进程：

$processID = Get-WmiObject -Computer $hostname -Class Win32_Service -Filter "Name='service_name'" |
             Select-Object -Expand ProcessID

(Get-Process -Computer $hostname -PID $processID).Kill()

请注意，某些服务被配置为不允许篡改其进程。在这种情况下，您可以尝试change the process settings。如果这不起作用（或者由于某种原因您不能这样做），您将不得不重新启动系统。
