使用PowerShell将绑定添加到IIS，而不会覆盖现有目录

Question

We use OctopusDeploy to create the website and we use the create website template that is on the community step sites. I have modified it slightly to ensure that if the website exists it adds the default binding however it is removing all the existing bindings. Is there a way to simply add a binding to IIS which overwrites if it already exists (or ignores) and doesn't remove all the existing bindings?

The script we currently have is as follows:

$bindingInformation = "${bindingIpAddress}:${bindingPort}:${bindingHost}"

$sitePath = ("IIS:\Sites\" + $webSiteName)

$site = Get-Item $sitePath -ErrorAction SilentlyContinue
if (!$site) { 
    Write-Output "Creating web site $webSiteName" 
    $id = (dir iis:\sites | foreach {$_.id} | sort -Descending | select -first 1) + 1
    new-item $sitePath -bindings ($wsBindings[0]) -id $id -physicalPath $webRoot -confirm:$false
} else {
    write-host "Web site $webSiteName already exists"
    Set-ItemProperty -Path $sitePath -Name Bindings -Value ($wsBindings[0])
}

It seems this line:

        Set-ItemProperty -Path $sitePath -Name Bindings -Value ($wsBindings[0])

Is overwriting all existing bindings but I can't seem to find a way around it.

Answer 1

You can use the New-WebBinding cmdlet:

  New-WebBinding `
        -Name $webSiteName `
        -Protocol 'http' `
        -Port $bindingPort `
        -IPAddress $bindingIpAddress `
        -HostHeader $bindingHost

And use Get-WebBinding cmdlet to check whether the binding already exists.

You can use New-WebBinding as jisaak said, that's mainly for http(s).

If you need to add other types of bindings, you have to use New-ItemProperty , instead of Set-ItemProperty .

New-ItemProperty -path "IIS:\Sites\YourSiteName" `
    -name bindings -value @{protocol="net.pipe";bindingInformation="SiteName"}
