Powershell-开始订购服务 [英] Powershell - Start ordered sequence of services

问题描述

我需要启动一个有序的服务序列，我需要每个服务都将启动并运行，然后再尝试启动下一个服务，如何在Powershell中实现这一点？

I need to start an ordered sequence of services, i need that each service will be up and running before try to start the next one, how can I achieve this in Powershell? How can I wait for the stop too?

谢谢，

推荐答案

如果您具有服务名称列表（例如数组），则foreach服务：

If you have a list of service names (say in an array), then foreach service:

1. 获取其状态


2. 如果未运行，则启动它


3. 在循环中有延迟，请检查其状态直到它运行为止

密钥可能正在处理所有可能性对于第3项，包括服务失败。

The key is likely to be handling all the possibilities for #3 including the service failing.

但是轮廓大概是（不处理错误情况）：

But an outline would be something like (without handling the error cases):

$serviceNames | Foreach-Object -Process {
  $svc = Get-Service -Name $_
  if ($svc.Status -ne 'Running') {
    $svc.Start()
    while ($svc.Status -ne 'Running') {
      Write-Output "Waiting for $($svc.Name) to start, current status: $($svc.Status)"
      Start-Sleep -seconds 5
    }
  }
  Write-Output "$($svc.Name) is running"
}

获取服务返回 System.ServiceProcess.ServiceController ，它是实时的，指示服务的当前状态，而不仅仅是创建实例时的状态。

Get-Service returns an instance of System.ServiceProcess.ServiceController which is "live"—indicating the current state of the service, not just the state when the instance was created.

类似的停止过程将用已停止和启动替换正在运行 ，然后点击停止。而且，大概可以颠倒服务列表的顺序。

A similar stop process would replace "Running" with "Stopped" and the "Start" call with "Stop". And, presumably, reverse the order of the list of services.
