Powershell Script to Create Sharepoint Web Application
Microsoft Sharepoint 2007 has a very nice web-based UI to create Web Applications, but there is one catch. The UI creates the backend database on the fly. In a lot of companies, this is the role of a DBA, and only they are allowed to create a new database. In a way this makes sense due to the fact that the DBAs must maintain the intergity of the database server. Microsoft has provided a switch within the stsadm command to create a new Web Application with an existing database, but I thought I could come up with a way to do it using Powersell.
What I wanted to do was to supply a script with an XML configuration that would create 1-N Web Applications with 1-N Sites. The XML looks like the following:
<Sharepoint>
<WebApplication name=”Test Site #1″ hostheader=”http://portal.example.net”>
<AppPoolName>WebApp-Portal</AppPoolName>
<AppPoolUser>Domain\myServiceAccount</AppPoolUser>
<AppPoolPass>test1235</AppPoolPass>
<Port>80</Port>
<DatabaseServer>DBS-SERVER-NAME\MOSS</DatabaseServer>
<DatabaseName>WSS_Content_Potal</DatabaseName>
<RootDirectory>d:\inetpub\wwwroot\wss\portal</RootDirectory>
<Sites>
<Site Path=”/”>
<Title>Root Site</Title>
<Description>Root Site</Description>
<Type>STS#1</Type>
<AdminAccount>DOMAIN\Administrator</AdminAccount>
<AdminName>Administrator1</AdminName>
<AdminEmail>root@jexample.net</AdminEmail>
</Site>
</Sites>
</WebApplication>
<WebApplication></WebApplication>
</Sharepoint>
The first thing that needs to be done is load the Sharepoint .NET assembly and attach to the local farm
[void][System.Reflection.Assembly]::LoadWithPartialName(“Microsoft.SharePoint”)
$farm = [microsoft.sharepoint.administration.spfarm]::local
Then load the XML configuration file and loop through all Web Applications.
function main()
{$moss = “Sharepoint”
$cfg = [xml](gc $cfgFile)if( $? -eq $false ) {
Write-Host “Could not cleanly parase XML file. Exiting . . .”
return $false
}Write-Host “Found Sharepoint Farm on Local Host . . “
Write-Host “Using $cfgFile file . . .”
$cfg.$moss.WebApplication | % {
createWebApp( $_ )
}
}main
Surprisingly to create new Web Application, all you need to do is create a Powershell object of type SPWebApplicationBuilder, assign the proper variables, create and then provision. The command can take up to 10 minutes to complete so be patient.
function createWebApp( [object] $cfg )
{
$webAppBuilder = $nul
$webAppBuilder = new-object _
microsoft.sharepoint.administration.SPWebApplicationBuilder($farm)$secureString = ConvertTo-SecureString $cfg.AppPoolPass -asPlainText -force
$webAppBuilder.Port = $cfg.port
$webAppBuilder.ApplicationPoolId = $cfg.AppPoolName
$webAppBuilder.ApplicationPoolUsername = $cfg.AppPoolUser
$webAppBuilder.ApplicationPoolPassword = $secureString$webAppBuilder.HostHeader = $cfg.hostheader
$webAppBuilder.ServerComment = $cfg.name
$webAppBuilder.DatabaseServer = $cfg.DatabaseServer
$webAppBuilder.DatabaseName = $cfg.DatabaseName
$webAppBuilder.RootDirectory = $cfg.RootDirectoryif( $cfg.AllowAnonymous.ToString().ToLower() -eq “true” ) {
$webAppBuilder.AllowAnonymousAccess = $true
}Write-Host “Will now Provision this Web Application.”
Write-Host “This may take up to 10 minutes. . .”
$webApp = $webAppBuilder.Create()
$webApp.Provision()
Finally, loop through all Sites that are listed in the XML and add them to the Web Application.
$cfg.Sites.Site | % {
$title = $_.SiteTitle.ToString()
$path = $_.Path.ToString()rite-Host “Will now Provision Site – $title ($path). “
Write-Host “This may take up to 10 minutes. . .”$webApp.Sites.Add( $_.Path,
$_.Title,
$_.Description,
1033,
$_.Type,
$_.AdminAccount,
$_.AdminName,
$_.AdminEmail)
}
See easy as 1, 2, 3 . . .
