How to set environmentalVariable to the application pool using powershell?

Question

please please anyone can tell me how to add these entries using powershell, I know I'm bit close but having errors.

<applicationPools>  
   <add name="Contoso" managedRuntimeVersion="v4.0" managedPipelineMode="Classic">  
      <environmentVariables>  
         <add name="foo" value="bar" />  
      </environmentVariables>  
   </add>  
</applicationPools>  

There is a cmd version of the command found on Microsoft:

appcmd.exe set config -section:system.applicationHost/applicationPools /+"[name='Contoso'].environmentVariables.[name='foo',value='bar']" /commit:apphost

but I need to do it through powershell

I'm trying something like this:

set-webconfigurationproperty -pspath 'machine/webroot/apphost' -filter "system.applicationhost/applicationpools/add[@DeezNutz ='Contoso']/environmentVariables" -name "foo" -value "bar"

WARNING: Property foo is not found on /system.applicationHost/applicationPools/add[@DeezNutz ='Contoso']/environmentVariables.

Please help

Answer 1

I finally found it.

Add-WebConfigurationProperty -pspath 'MACHINE/WEBROOT/APPHOST'  -filter "system.applicationHost/applicationPools/add[@name='Auth']/environmentVariables" -name "." -value @{name='aaa';value='zzzz'}  

In the configuration editor, I navigated to my Auth app pool and added an environment variable using the collection editor. Then click on the Generate Script action and copy the Powershell statement.

Powershell will happily run executables for you. Just run the appcmd.exe version in your PS script.

Try using Add--webconfigurationproperty instead of Set-webconfigurationproperty.

Answer 3

I just wonder, there must be a way. Add--webconfigurationproperty does nothing but empty command line without errors, no changes are made.

By the way, I'm trying all these because I need global variable to be used in php application. Problem is that .user.ini file is not honored from a virtual directory, IIS sees it only from physical directory, I would be glad to hear any suggestions!!!
