Create IIS App Pool and Site With Windows Powershell

Here’s a simple code snippet which shows how to create a new app pool and site in IIS via a Powershell script. It also checks for app pool and site existence before trying to create new items. It’s quite a nice example of why Powershell is so easy to work with- yes, you can achieve the same thing in a batch file, but this is just so much cleaner:

Import-Module WebAdministration
$iisAppPoolName = "my-test-app"
$iisAppPoolDotNetVersion = "v4.0"
$iisAppName = "my-test-app.test"
$directoryPath = "D:\SomeFolder"

#navigate to the app pools root
cd IIS:\AppPools\

#check if the app pool exists
if (!(Test-Path $iisAppName -pathType container))
    #create the app pool
    $appPool = New-Item $iisAppPoolName
    $appPool | Set-ItemProperty -Name "managedRuntimeVersion" -Value $iisAppPoolDotNetVersion

#navigate to the sites root
cd IIS:\Sites\

#check if the site exists
if (Test-Path $iisAppName -pathType container)

#create the site
$iisApp = New-Item $iisAppName -bindings @{protocol="http";bindingInformation=":80:" + $iisAppName} -physicalPath $directoryPath
$iisApp | Set-ItemProperty -Name "applicationPool" -Value $iisAppPoolName
