如何使用Powershell回收IIS AppPool? [英] How do I recycle an IIS AppPool with Powershell?

问题描述

我根本还没有完成任何Windows脚本编写工作，因此我对如何实现这一功能一无所知.无论如何，基本上我们想要做的是有一个脚本，该脚本将带有一个参数，以决定对哪个IIS AppPool进行回收.我已经在Google上进行了一些研究，但在使事情正常进行方面并没有取得太大的成功.

I haven't really done any Windows scripting at all, so I am at a loss on how to pull this one off. Anyway, basically what we want to do is have a script that will take an argument on which IIS AppPool to recycle. I have done some research on Google and haven't had much success on getting things to work.

这是我现在正在尝试的内容:

Here is what I am trying now:

$appPoolName = $args[0]
$appPool = get-wmiobject -namespace "root\MicrosoftIISv2" -class "IIsApplicationPools" Where-Object {$_.Name -eq "W3SVC/APPPOOLS/$appPoolName"}
$appPool.Recycle()

和我得到的错误:

Get-WmiObject : A parameter cannot be found that matches parameter name '$_.Name -eq "W3SVC/APPPOOLS/$appPoolName"'.

无论如何，如果我也知道如何调试这样的事情，那就太好了.我已经通过执行gwmi -namespace"root \ MicrosoftIISv2" -list修复了原始脚本的一个错误.像这样的任何其他技巧都很好.

Anyway, it would be nice if I also knew how to debug things like this. I already fixed one bug with the original script by doing gwmi -namespace "root\MicrosoftIISv2" -list. Any other tips like that one would be great.

谢谢！

推荐答案

Where-Object 是一个过滤器，期望输入中包含某些内容.在 where过滤器之前，似乎缺少了管道.

Where-Object is a filter that expects something as in input. There seems to be a missing pipe, before the where filter.

尝试:

$appPoolName = $args[0]
$appPool = get-wmiobject -namespace "root\MicrosoftIISv2" -class "IIsApplicationPool" | Where-Object {$_.Name -eq "W3SVC/APPPOOLS/$appPoolName"}
$appPool.Recycle()

编辑:我注意到WMI类是 IISApplicationPools ，如您所见，当通过管道传输到 Get-Member .这需要更改为 IISApplicationPool (非复数).进行此更改后，您就可以使用Recycle方法.上面的代码已更新.

Edit: I noticed that the WMI class was IISApplicationPools, which as you saw, did not show us the Recycle method when piped to Get-Member. This needs to be changed to IISApplicationPool (non-plural). With that change, you are able to use the Recycle method. The code above has been updated.
