如何使用PowerShell使用增量值设置一组IIS网站的绑定端口号？

Question

I have an IIS back end server with many websites. I just created these sites using powershell. I need to set the binding port for each website to a unique number (starting at 9200) for the proxy. I am trying to find a way to script this out, but I am having a hard time trying to find a solution to this one. Currently I have a list of websites in a text file I want to set the binding port for. Right now this is what I have:

Import-Module WebAdministration

$endpoints = Get-Content C:\scripts\endpoints.txt

foreach ($number in 9200..9310)
{
    foreach ($site in $endpoints)
        {
    Set-WebBinding -Name '$site' -BindingInformation "*:80:" -PropertyName Port -Value $number
    }
  }

The reason I have the first foreach loop is to get the port numbers from 9200-9310 since I have 110 websites in total. Am I going about this the wrong way?

Answer 1

It seems the issue is your two foreach loops. You have your second foreach loop inside of the one containing the port numbers. Therefore, your first loop starts at $number = 9200 and then sets EACH $site equal to the port held in your $number variable at that time and then exits that loop and increments the port number and starts again.

Here is something I came up with that I believe will solve your problem.

Import-Module WebAdministration
$endpoints = Get-Content C:\scripts\endpoints.txt

$ports = New-Object System.Collections.ArrayList
[int] $port = 9200
[int] $counter = 0

while($port -le 9310) {
  $ports.Add($port)
  $port++
}

foreach ($site in $endpoints)
{
   Set-WebBinding -Name '$site' -BindingInformation "*:80:" -PropertyName Port -Value $ports[$counter]
   $counter++
}
