Recycle Application Pool using Powershell Script

问题

I want to recycle my application pool using one liner command which I can put in my powershell script. I added the following code in my powershell script:

Import-Module WebAdministration

$site = "Default Web Site"

$pool = (Get-Item "IIS:\Sites\$site"| Select-Object applicationPool).applicationPool

Restart-WebAppPool $pool

But I am getting an error that name IIS doesn't exist. Please advise

I like when answers are short and simple, like this...

Restart-WebAppPool (Get-Website -Name <YourSiteName>).applicationPool

回答2:

You can use appcmd.exe:

appcmd recycle apppool /apppool.name='MyAppPool'

---

You can also retrieve the corresponding WMI instance and invoke the Recycle() method:

$myAppPool = Get-WmiObject -Namespace root\WebAdministration -Class ApplicationPool -Filter "Name = 'MyAppPool'"
$myAppPool.Recycle()

Import-Module WebAdministration

$site = "MySite"
$pool = (Get-Item "IIS:\Sites\$site"| Select-Object applicationPool).applicationPool

#Recycle the application pool:
Restart-WebAppPool $pool

The following command works for me

invoke-command -computername servername -scriptblock {C:\Windows\System32\inetsrv\appcmd.exe recycle apppool "apppoolname"}

Maybe someone will find this one useful as well:

Write-Host "App Pool Recycling Started...."
& $env:windir\system32\inetsrv\appcmd list apppools /state:Started /xml | & $env:windir\system32\inetsrv\appcmd recycle apppools /in 
Write-Host "App Pool Recycling Completed"

Works for me in AWS through Run command.
