IIS: how to undeploy/delete/remove a webapp from command line? - iis

Suppose there's a webapp deployed on local IIS server. When I need to remove/undeploy it, I can go to IIS Manager, right-click on the app, and then select "Delete application and content" - et voila. But, I need to do the same from the command line - how? It can be assumed that the name of the application is known.
Maybe this can be done via MSDeploy somehow?

If you just want to remove the application from the Web Site in IIS without physically deleting the files (like msdeploy does) or if you don't have the WebDeploy-extension installed, you can use the following command:
C:\Windows\System32\inetsrv\appcmd.exe delete app "Default Web Site/MyAppName"

This is what did it:
"C:\Program Files\IIS\Microsoft Web Deploy\msdeploy" -verb:delete -dest:apphostconfig="Default Web Site/<webapp_name>"

I know the question says "command line", but you can use PowerShell and the IIS Administration Cmdlets to do this task. I provide all of the functions and explain the process of how to automate this on my blog. Also, you can easily swap out the IIS Administration Cmdlet calls with calls to msdeploy, appcmd, IIsVdir.vbs, etc.
For your specific question, this PowerShell code should do the trick:
$block = {
Import-Module WebAdministration
$website = "YourWebsiteName"
$applicationName = "PathUnderWebsite\ToYourApplication"
$fullPath = Join-Path $website $applicationName
Write-Host "Checking if we need to remove '$fullPath'..."
if (Get-WebApplication -Site "$website" -Name "$applicationName")
{
Write-Host "Removing '$fullPath'..."
Remove-WebApplication -Site "$website" -Name "$applicationName"
}
Write-Host "Deleting the directory '$fullPath'..."
Remove-Item -Path "IIS:\Sites\$fullPath" -Recurse -Force
}
$session = New-PSSession -ComputerName "Your.WebServer.HostName"
Invoke-Command -Session $session -ScriptBlock $block
Remove-PSSession -Session $session

iisweb /delete WebSite [/s Computer [/u [Domain ]User /p Password ]]

unable to append data to sharepoint file via Azure Automation

Ok I have asked a question like this but now I am trying to perform the task via Azure Automation. I can connect to the SharePoint site via Azure Automation (powershell). with the correct credentials. I can download the file and append data to it. But I can when I try and upload the file back to SharePoint it adds the contents 3 times and then Azure Automation suspends the Runbook after 3 times.
It does run perfect if I upload this file as a different file name.
$siteurl="https://abc.sharepoint.com/sites/xxx/teamsites/os"
$credSP = Get-AutomationPSCredential -Name 'test'
$fileFolder = "$Env:temp"
Connect-PnPOnline -Url $siteurl -Credentials $credSP
Get-PnPFile -Url "/sites/xxx/teamsites/os/Directory and Operating
Systems/test.csv" -Path $fileFolder -Filename test.csv -AsFile -Force
$test = "31-07-2019 -11:35"
Add-Content -Path $fileFolder\test.csv $test
Add-PnPFile -Path $fileFolder\test.csv -Approve -Folder "Directory and
Operating Systems" #-ErrorAction Ignore
Here are the results
test test
31-07-2019 -11:35
31-07-2019 -11:35
31-07-2019 -11:35
As you can see it added $test 3 times. But I dont have this issue if I upload it as a new file name.
Ok after a while I have fix the issue.
After the add-pnpfile ...... you pipe it to | out-null
Thats it. the sript stops after it uploads ,
happy days

How to find out MACHINE/WEBROOT/APPHOST location of an application

I am currently writing a security auditing script for IIS 10 in Powershell. I have never even remotely worked with IIS before. I am supposed to run commands like this:
Get-WebConfigurationProperty -pspath 'MACHINE/WEBROOT/APPHOST/<website name>' -filter 'system.web/authentication/forms' -name 'protection'
Where can I find the website name ?
Thanks
As lex mentioned, we could use Get-Website or WebApplication to iterate all sites/applications.
If you just want to list the website name in the Powershell you could add below command.
Get-WebSite | Format-List -Property Name
Result example:

Using Powershell to create a web application in a folder that is not an application

I want to create a web application in IIS that does not live at the root of the IIS site.
i.e. MySite/beta/WebApplication.
This is my starting point:
New-WebApplication "WebApplication" -Site "MySite" -ApplicationPool "MyAppPool" -PhysicalPath "C:\Sites\MySite\beta\WebApplication"
That creates me the physical structure I want C:\Sites\MySite\beta\WebApplication , but makes IIS look like this:
MySite (IIS Web Site)
WebApplication (IIS WebApplication)
beta (Folder)
WebApplication (Folder)
Is there a way this can be done via powershell? I do not really want beta to be a web application, just a folder.
I know this post is a little older but here is a powershell script I wrote that converts an existing folder to a web application in IIS or if it doesn't exist creates a new folder and web app. It also creates the app pool for it as well. It receives an array of app names so you can create more than one web application. This was my first powershell script so if you have any suggestions feel free to comment.
#Receives an array of appnames and creates the app pools and web applications or converts the folder to an application
Param([parameter(Mandatory=$true)][string[]]$appNames)
$useDefaultPhysicalPath = Read-Host "Would you like to use the default physical path? (C:\inetpub\wwwroot\)";
Import-Module WebAdministration;
$physicalPath = "C:\inetpub\wwwroot\";
if(!($useDefaultPhysicalPath.ToString().ToLower() -eq "yes" -or $useDefaultPhysicalPath.ToString().ToLower() -eq "y"))
{
$physicalPath = Read-Host "Please enter the physical path you would like to use with a trailing \ (do not include the app name)";
}
$appPath = "IIS:\Sites\Default Web Site\";
foreach($appName in $appNames)
{
if((Test-Path IIS:\AppPools\$appName) -eq 0)
{
New-WebAppPool -Name $appName -Force;
}
if((Test-Path $appPath$appName) -eq 0 -and (Get-WebApplication -Name $appName) -eq $null)
{
New-Item -ItemType directory -Path $physicalPath$appName;
New-WebApplication -Name $appName -ApplicationPool $appName -Site "Default Web Site" -PhysicalPath $physicalPath$appName;
}
elseif((Get-WebApplication -Name $appName) -eq $null -and (Test-Path $appPath$appName) -eq $true)
{
ConvertTo-WebApplication -ApplicationPool $appName $appPath$appName;
}
else
{
echo "$appName already exists";
}
}
Since you are using the same physical file repository that is used by the "MySite" collection, it will create the "beta" folder. If you place this new web application in its own path (i.e., "C:\Sites\WebApps\WebApplication") you will get the desired results. The code below worked for me.
New-WebApplication "TestingViaPosh" -Site "Default Web Site" -ApplicationPool "DefaultAppPool" -
PhysicalPath "C:\Users\MyUserId\Documents\TestWebApp"
EDIT: To create a web application in a folder underneath the root of a website, you need to first create the folder in the site you desire (i.e., "C:\Sites\MySite\Beta"). Then the Powershell command will look like this:
New-WebApplication "TestingViaPosh" -Site "Default Web Site\Beta" -ApplicationPool "DefaultAppPool" -PhysicalPath "C:\Users\MyUserId\Documents\TestWebApp"
Since some people use the term folder and Virtual Directory, I thought it would be worth posting how you create a New Web Application inside a Folder / Virtual Directory. Which looks like this in IIS Manager.
You simply need to use the Path as the site name.
Import-Module WebAdministration
$SiteName = "Act.Web.API" # IIS Site Name
New-WebVirtualDirectory -Site $SiteName -Name APFW-api -PhysicalPath C:\inetpub\wwwroot
New-WebApplication -Name Act.Web.API -Site $SiteName\APFW-api -PhysicalPath "C:\Program Files (x86)\ACT\APFW-api" -ApplicationPool $SiteAppPool
$SiteName\APFW-api equals "Act.Web.API\APFW-api" at run time so the highlighted application is created.

PowerShell Split-Path does not work properly with IIS: drive qualifier

I am using PowerShell v3.0 and the IIS Administration Cmdlets to add and remove websites from my IIS 7 instance. I use Import-Module WebAdministration to make sure the IIS: drive is available, and I am able to use Remove-Item to delete files via the IIS: drive. For some reason though when I use the following code Split-Path always returns an empty string, even though the Remove-Item works fine.
$iisPath = Join-Path "IIS:\Sites" $fullPath
Remove-Item -Path $iisPath
$parent = Split-Path -Path $iisPath -Parent
Even if I comment out the Remove-Item line, Split-Path still returns an empty string. The $iisPath value would look something like this:
IIS:\Sites\Application Services\2.5.12\OurProductServicesDirectory
So I would expect $parent to contain:
IIS:\Sites\Application Services\2.5.12
But $parent is always empty. I have also tried creating the $iisPath using $iisPath = "IIS:\Sites\$fullPath", rather than Join-Path, but still get the same result.
Any ideas why Split-Path doesn't seem to work when using the IIS: drive, or how to fix it?
===UPDATE===
So I created a tiny sample script to see if I could reproduce the problem. Here it is:
$Block = {
Import-Module WebAdministration
$path = "IIS:\Sites\Application Services\2.5.12\OurProductServicesDirectory\"
Test-Path -Path $path
$parent = Split-Path -Path $path -Parent
Write-Host Parent is $parent
}
$Session = New-PSSession -ComputerName "Our.WebServer.local"
Invoke-Command -Session $Session -ScriptBlock $Block
Using this script $parent does get a value, but the text written to the console is:
True
Parent is IIS:Sites\Application Services
when I expect it to be:
True
Parent is IIS:\Sites\Application Services\2.5.12
So in my simple sample script I do get a value back, but it's the wrong value; it returns the grandparent directory instead of the parent directory, and it removes the backslash from after IIS:.
I'm not sure why I get different results in this sample script then in my main script, but both results appear to be wrong. Any suggestions are appreciated.
So because the IIS: qualifier is made valid by importing the WebAdministration module, I'm going to assume that Split-Path was simply never designed to work with the IIS: qualifier, and that is why it doesn't handle it properly.
The work around I found was simply to just exclude IIS:\Sites\ from my path when using Split-Path. So my original example would change to:
Remove-Item -Path "IIS:\Sites\$fullPath"
$parent = Split-Path -Path $fullPath -Parent
So basically I just leave IIS:\Sites\ off of all my paths, and then explicitly add it when needed, such as when calling Remove-Item, Test-Path, Get-ChildItems, etc. It's not the greatest solution, but it works.

Get dbname from multiple web.config files with powershell

I would like to issue a powershell command to return me the connection string (specifically I am looking for the db name value) for all the web sites on a web server...
So I would like to see something like
site1 dbname=Northwind
site2 dbname=Fitch
site3 dbname=DemoDB
I have tried using the IIS Powershell snap-in... I thought I was close with this:
PS C:\Windows\system32> Get-WebApplication | Get-WebConfiguration -filter /connectionStrings/*
but... after looking at the results... my answer doesn't appear to be in there
I am very new to powershell - so excuse my ignornance and inexperience
Any help appreciated!
thanks!
Hopefully, this will get you started. This just assumes there will be a web.config file at the physical path of the web application's physical path. It does not recurse to find other web.config files in the web application. It also assumes your connection strings are in the connectionStrings configuration element.
Import-Module WebAdministration
Get-WebApplication | `
ForEach-Object {
$webConfigFile = [xml](Get-Content "$($_.PhysicalPath)\Web.config")
Write-Host "Web Application: $($_.path)"
foreach($connString in $webConfigFile.configuration.connectionStrings.add)
{
Write-Host "Connection String $($connString.name): $($connString.connectionString)"
$dbRegex = "((Initial\sCatalog)|((Database)))\s*=(?<ic>[a-z\s0-9]+?);"
$found = $connString.connectionString -match $dbRegex
if ($found)
{
Write-Host "Database: $($Matches["ic"])"
}
}
Write-Host " "
}
This post may give you an idea to start with. Basically load in the web.config file as an XML file and then just find the node where the connection string is.
Do something like $myFile = ([xml] Get-Content web.config). You can then pipe that to Get-Member ( $myFile | Get-Member -MemberType Property) to start working your way into the file to see what node has it. I'm not at a computer where I can show you some screenshots to explain it more, but you can check this chapter out from PowerShell.com "Master PowerShell" e-book that explains working with XML very well.
