如何強制停止處於「停止等待」狀態的一個或多個服務

Question

我想停止Windows服務並掛起或掛起狀態爲Stopping。我們正在使用混合操作系統，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" 
    } 
} 

此外，我的代碼上面我想輸出格式化爲一行，我是正確的嗎？例如：

scxagent  sshstatus  AgentPortStatus AgentServStatus 
Server1  OK   OK     STOPPED 
Server2  NOT OK  NOT OK    RUNNING 
etc.

最後更新：

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" 
    } 
} 

錯誤消息：

ERROR: Cannot overwrite variable PID because it is read-only or constant. 
getservice.ps1 (32): ERROR: At Line: 32 char: 3 
ERROR: +   $pid = Get-WmiObject -Computer $hostname -Class Win32_Service -Filter "Name='A ...

如果接收到停止請求「逼停」它是殺害的唯一途徑後服務掛起該過程如@autsvet已經提到。使用PID來標識進程：

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

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

請注意，某些服務配置爲不允許篡改其進程。在這種情況下，您可以嘗試change the process settings。如果這不起作用（或者出於某種原因你不能這麼做），你將不得不重新啓動系統。
