如何使用Powershell回收IIS AppPool？

Question

我根本没有真正完成任何Windows脚本,所以我对如何解决这个问题感到茫然.无论如何,基本上我们想要做的是有一个脚本,它将对哪个IIS AppPool进行回收.我已经对谷歌进行了一些研究,并且在开展工作方面没有取得多大成功.

这是我现在正在尝试的:

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

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会很好.我已经通过执行gwmi -namespace"root\MicrosoftIISv2"-list修复了原始脚本的一个错误.像那样的任何其他提示都会很棒.

谢谢!

更新:这里有更多信息

$appPool = gwmi -namespace "root\MicrosoftIISv2" -class "IISApplicationPools" | Get-Member

Answer 1

Where-Object是一个过滤器,它在输入中需要某些东西.在过滤器之前,似乎缺少管道.

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,正如您所见,在向Get-Member传送时没有向我们展示Recycle方法.这需要更改为IISApplicationPool(非复数).通过该更改,您可以使用Recycle方法.上面的代码已更新.

使用这个问题的数据,我能够创建2个非常有用的功能.

• GET-IisAppPools
• 循环型IisAppPool

代码:

function Get-IisAppPools {

    Get-WmiObject -Namespace "root\MicrosoftIISv2" -Class "IIsApplicationPool" -Filter 'name like "W3SVC/APPPOOLS/%"' 
         | ForEach-Object { $_.Name.ToString().SubString(15) } 

}

function Recycle-IisAppPool([string]$appPoolName) { 

     Invoke-WmiMethod -Name Recycle -Namespace "root\MicrosoftIISv2" -Path "IIsApplicationPool.Name='W3SVC/APPPOOLS/$appPoolName'" 

}

你可以使用这样的功能

Recycle-IisAppPool DefaultAppPool
Get-IisAppPools | ? { $_ -match "v4.0$" } | % { Recycle-IisAppPool $_ }
