In this walkthrough you will learn how to create Web-Sites, Web Applications, Virtual Directories and Application Pools.
Introduction
The IIS PowerShell namespace consists of items like Web-Sites, Apps, Virtual Directories and Application Pools. Creating new namespace items and managing them is very easy using the built-in PowerShell cmdlets.
Creating Web-Sites
If you are familiar with PowerShell you know that the New-Item cmdlet is used to create new items in the various PowerShell namespaces. The command "New-Item c:\TestDirectory" creates a new filesystem directory for example (most people use the "MD" or "MKDIR" alias for New-Item however). New-Item is also used to create new Web-Sites within the IIS 7.0 PowerShell namespace.
Parameters
Specifying the name of the directory is the only argument needed when you create a new file system directory. Unfortunately this is not enough when you create a Web-Site. Additional parameters like the file system path and network bindings are needed to create a Web-Site. Here is the command to create a new Web-Site followed by a dir command:
PS IIS:\Sites> New-Item iis:\Sites\TestSite -bindings @{protocol="http";bindingInformation=":80:TestSite"} -physicalPath c:\test
PS IIS:\Sites> dir
Name ID State Physical Path Bindings
---- -- ----- ------------- --------
Default Web Site 1 Started f:\inetpub\wwwroot http *:80:
TestSite 2 Started c:\test http :80:TestSite
Using the -physicalPath argument is pretty straightforward. But you might ask yourself why the -bindings argument looks so complex.
The construct used is a hashtable (go here to learn more about PowerShell hash tables). Within the hash table key=value pairs indicate the settings that reflect the attributes within the IIS site bindings section:
<bindings>
<binding protocol="http" bindingInformation=":80:TestSite" />
</bindings>
Now here is the reason why we use a hash table: IIS configuration is completely extensible (see here for more details) with additional sections and attributes. You can imagine that somebody extending the <binding> element with additional attributes. Key value pairs within a hash table provide the flexibility to incorporate these new attributes without having to completely rewrite the IIS PowerShell Snap-in.
Granted, the syntax is a bit complex. We are thinking about wrapping some typical tasks like creating sites with additional functions or scripts in a later Tech Preview.
Deleting Sites
Here is how you delete the site you just created.
PS IIS:\ >Remove-Item IIS:\Sites\TestSite
Creating Web Applications
Creating Web Applications is easier than creating sites. Here we go:
PS IIS:\> New-Item 'IIS:\Sites\Default Web Site\DemoApp' -physicalPath c:\test -type Application
Name ApplicationPool EnabledProtocols PhysicalPath
---- --------------- ---------------- ------------
DemoApp DefaultAppPool http c:\test
The only parameter you have to specify is the type (-type) because underneath a Web-Site you might want to create an Applications or a Virtual Directories. By specifying the -type parameter you tell the IIS Snap-in to create an application.
To delete the application you can also use Remove-Item.
Creating Virtual Directories
To create a Virtual Directory you also use the New-Item cmdlet. Let's create a Virtual Directory underneath the 'Default Web Site' but and a second one underneath the Web Application we created in the previous step.
PS IIS:\> New-Item 'IIS:\Sites\Default Web Site\DemoVirtualDir1' -type VirtualDirectory -physicalPath c:\test\virtualDirectory1
Name PhysicalPath
---- ------------
DemoVirtualDir1 c:\test\virtualDirectory1
PS IIS:\> New-Item 'IIS:\Sites\Default Web Site\DemoApp\DemoVirtualDir2' -type VirtualDirectory -physicalPath c:\test\virtualDirectory2
Name PhysicalPath
---- ------------
DemoVirtualDir2 c:\test\virtualDirectory2
Creating Application Pools
But it gets even simpler. Creating a new AppPool only requires the name to be specified.
PS IIS:\> new-item AppPools\DemoAppPool
Name State
---- -----
DemoAppPool {}
Simple, wasn't it? Now let's put this together to an end-to-end scenario.
Putting it all Together
In the following end-to-end scenario we will execute the following step:
-
Create a set of new file system directories for the sites, web applications and virtual directories we will create a little later.
-
Copy some very simple web content into the newly created directories.
-
Create new Application Pool
-
Create a new site, a new application and two new virtual directories and assign them to newly created Application Pool.
-
Request the web content via the web browser.
Step 1: Create New Directories
We use the New-Item cmdlet to create four new file system directories. Execute the following commands (use 'md' instead of New-Item if you don't want to specify the -type parameter):
New-Item C:\DemoSite -type Directory
New-Item C:\DemoSite\DemoApp -type Directory
New-Item C:\DemoSite\DemoVirtualDir1 -type Directory
New-Item C:\DemoSite\DemoVirtualDir2 -type Directory
Step 2: Copy Content
Now let's write some simple html content to these directories:
Set-Content C:\DemoSite\Default.htm "DemoSite Default Page"
Set-Content C:\DemoSite\DemoApp\Default.htm "DemoSite\DemoApp Default Page"
Set-Content C:\DemoSite\DemoVirtualDir1\Default.htm "DemoSite\DemoVirtualDir1 Default Page"
Set-Content C:\DemoSite\DemoVirtualDir2\Default.htm "DemoSite\DemoApp\DemoVirtualDir2 Default Page"
Step 3: Create New Application Pool
Create the new Application Pool 'DemoAppPool' for the new site if you deleted the one we created in the previous sample.
New-Item IIS:\AppPools\DemoAppPool
Step 4: Create New Sites, Web Applications and Virtual Directories and Assign to Application Pool
Here comes the beef. We create DemoSite, DemoApp and two Virtual Directories - DemoVirtualDir1 is directly underneath DemoSite and DemoVirtualDir2 is underneath DemoApp. We are assigning DemoSite and DemoApp to DemoAppPool created in the previous step. DemoSite is assigned to port 8080 to not conflict with the 'Default Web Site'
New-Item IIS:\Sites\DemoSite -physicalPath C:\DemoSite -bindings @{protocol="http";bindingInformation=":8080:"}
Set-ItemProperty IIS:\Sites\DemoSite -name applicationPool -value DemoAppPool
New-Item IIS:\Sites\DemoSite\DemoApp -physicalPath C:\DemoSite\DemoApp -type Application
Set-ItemProperty IIS:\sites\DemoSite\DemoApp -name applicationPool -value DemoAppPool
New-Item IIS:\Sites\DemoSite\DemoVirtualDir1 -physicalPath C:\DemoSite\DemoVirtualDir1 -type VirtualDirectory
New-Item IIS:\Sites\DemoSite\DemoApp\DemoVirtualDir2 -physicalPath C:\DemoSite\DemoVirtualDir2 -type VirtualDirectory
Voila. All that's left is to request the web content.
Step 5: Request the Web Content
You can of course open the browser and enter http://localhost:8080/ and all the other URLs. But its a PowerShell walkthrough and we'll use PowerShell to do it by using the .NET WebClient classes:
$webclient = New-Object Net.WebClient
$webclient.DownloadString("http://localhost:8080/");
$webclient.DownloadString("http://localhost:8080/DemoApp");
$webclient.DownloadString("http://localhost:8080/DemoVirtualDir1");
$webclient.DownloadString("http://localhost:8080/DemoApp/DemoVirtualDir2");
If you feeling adventurous you can also use Internet Explorer object itself:
$ie = new-object -com InternetExplorer.Application
$ie.Visible = $true
$ie.Navigate("http://localhost:8080/");
Summary
In this walkthrough you learned how to create Web-Sites, Web Applications, Virtual Directories and Application Pools with PowerShell. Additional PowerShell features were used to build a functional end-to-end scenario.
