IIS7.5 PowerShell 预加载已启用

Question

我是否可以使用 PowerShell 命令（例如，New-WebSite）来创建网站并设置网站的 preloadEnabled="true"？

Answer 1

This should do the trick. You can use the get-itemproperty to verify that it worked. It took me a while to figure out where to find preloadEnabled within powershell but if you pipe the site path to get-member , then you can work your way from there.

import-module webadministration
set-itemproperty IIS:\Sites\SiteName -name applicationDefaults.preloadEnabled -value True

Answer 2

There is in fact a way to do this (assuming you have a single application at / that you want to set it for and you know the name of your site):

[System.Reflection.Assembly]::LoadFrom("C:\windows\system32\inetsrv\Microsoft.Web.Administration.dll")
$serverManager = (New-Object Microsoft.Web.Administration.ServerManager)
$serverManager.Sites["YOUR_SITE_NAME"].Applications["/"].SetAttributeValue("preloadEnabled", $true)
$serverManager.CommitChanges()

Answer 3

This is a bit late, but this will help others... This worked for me and was a little less verbose. The key difference is that I removed ApplicationDefaults because I am setting the application, not the defaults here:

Set-ItemProperty IIS:\Sites\<siteName>\<applicationName> -name preloadEnabled -value True

WHERE: 'SiteName' might equal Default Web Site 'ApplicationName' might equal MyApplication

Answer 4

You can enable preload for the root application of a website like this:

$w = New-Item "IIS:\Sites\AAA" -type site –physicalPath "C:\W" -bindings $binding
$w.Collection[0].preloadEnabled = $true
$w | Set-Item

Answer 5

I could offer more granular and deterministic approach:

# Creating the website:
$website = New-WebSite -Name $WebSiteName -PhysicalPath $WebSiteFolder -ApplicationPool $PoolName

# Setting preload enabled:
Set-WebConfigurationProperty `
    -PSPath "IIS:\" `
    -Filter "/system.applicationHost/sites/site[@name='$WebSiteName']/application[@path='/']" `
    -Name "preloadEnabled" `
    -Value $True  # or $False to turn that off

Answer 6

I've been looking for this too, but couldn't find anything in WebAdministration to set this option. Presumably the approach would be to call New-ItemProperty on the correct WebApplication. Unfortunately, I was unable to get the "default" application for a given website, or to set this property on it. It kinda seems like the WebAdministration module (which enables cmdlets like New-WebSite) was written with earlier versions of IIS in mind, and certainly before the Application Initialization module.

This is a workaround, which forces the setting of these properties by editing the underlying applicationHost.config file. This is a slightly simplified version of a script we're now using. You'll need to run this script as an administrator.

# Copy applicationHost.config to the temp directory,
# Edit the file using xml parsing,
# copy the file back, updating the original

$file = "applicationhost.config"
$source = Join-Path "$env:windir" "\system32\inetsrv\config\$file"
$temp = Join-Path "$env:temp" "$([Guid]::NewGuid().ToString())"
$tempFile = Join-Path "$temp" "$file"

#update all applications in websites whose name matches this search term
$search = "website name to search for"

#copy applicationHost.config to  temp directory for edits
#assignments to $null simply silence output
$null = New-Item -itemType Directory -path $temp
$null = Copy-Item "$source" "$temp"

# Load the config file for edits
[Xml]$xml = Get-Content $tempFile

# find sites matching the $search string, enable preload on all applications therein
$applications = $xml.SelectNodes("//sites/site[contains(@name, `"$search`")]/application") 
$applications | % { 
    $_.SetAttribute("preloadEnabled", "true") 
}

#save the updated xml
$xml.Save("$tempFile.warmed")

#overwrite the source with updated xml
Copy-Item "$tempfile.warmed" "$source"

#cleanup temp directory
Remove-Item -recurse $temp

Old question, but I wanted to share my insights.

I needed to do this from an Octopus post-deployment script, where my App was in the Site root. I tried all the suggested solutions here and the one from Robert Moore was the only one working for me.

However, I ended up using this which also did the job:

$Site = Get-Item IIS:\Sites\<site name>
$Site.applicationDefaults.preloadEnabled = $true
$Site | Set-Item -Verbose
