This is one of the recent additions to my SharePoint 2010 PowerShell scripts & Utilities project on Codeplex. I wrote a generic script cmdlet to take care of iFilter MSI install, make changes to DOCICON.XML, and add the crawl extension to the search service application.
This could be useful to those who perform frequent SharePoint 2010 farm configuration. You can copy just this script @ http://pssp2010utils.codeplex.com/SourceControl/changeset/view/14b6c2e1b6ec#SPInstallUtils.psm1
This script requires to be run at the SharePoint 2010 management shell since there is a dependency on New-SPEnterpriseSearchCrawlExtension cmdlet.
IFilter Install
Whatever iFilters I’d Installed so far were all MSI with silent install support. So, making this a generic script cmdlet was a choice for me.
function Install-SPIFilter { [CmdletBinding()] param ( [Parameter(Mandatory=$true)] [ValidateScript({ if ((Get-Item $_).Extension -eq ".msi") {$true}})] [String]$IFilterMSI, [Parameter(Mandatory=$true)] [String]$filetype, [Parameter(Mandatory=$false)] [String]$Icon, [Parameter(Mandatory=$true)] [String]$SearchServiceApplicationId ) $script:TEMPLATE = $("$env:CommonProgramFiles\Microsoft Shared\Web Server Extensions\14\TEMPLATE") #Install MSI Write-Host Write-Host -NoNewline "Installing $IFilterMSI" try { $msiProcess = [System.Diagnostics.process]::Start("msiexec","/i $IFilterMSI /quiet /qn") $msiProcess.WaitForExit() if ($msiProcess.ExitCode -ne 0) { Write-Host -ForegroundColor Red "`t [Error]" Return $false } else { Write-Host -ForegroundColor Green "`t [Done]" } } catch { Write-Error "`nThere was an error starting the install process" } #Add docicon if $icon exists if ($icon) { Write-Host Write-Host -NoNewline "Adding $icon to DOCICON.XML" $iconName = (Get-Item $icon).Name #Copy the icon file to 14 hive Copy-Item -Path $icon -Destination $("$Script:TEMPLATE\IMAGES") -Force #Create a copy of DOCICON.XML Copy-Item -Path "$script:TEMPLATE\XML\DOCICON.XML" -Destination "$script:TEMPLATE\XML\DOCICON.BAK" -Force #Read XML try { $xml = New-Object XML $xml.Load("$script:TEMPLATE\XML\DOCICON.XML") $cloneNode = @($xml.DocIcons.ByExtension.Mapping)[0] $newNode = $cloneNode.Clone() $newNode.Key = $fileType $newNode.Value = $iconName $newNode.EditText = $fileType $newNode.OpenControl = "" $xml.DocIcons.ByExtension.AppendChild($newNode) | Out-Null $xml.Save("$script:TEMPLATE\XML\DOCICON.XML") } catch { Write-Error "`nError occurred while loading/manipulating XML" return $false } Write-Host -ForegroundColor Green "`t [Done]" } #Add crawl extension Write-Host Write-Host -NoNewline "Adding crawl extension" try { New-SPEnterpriseSearchCrawlExtension -Name $fileType -SearchApplication $SearchServiceApplicationId | Out-Null } catch { Write-Error "`nError occured while adding crawl extension" return $false } Write-Host -ForegroundColor Green "`t [Done]" return $true }
