Powershell 和 Machine.config 帮助

我对powershell很陌生,如果可能的话,我需要一个快速的手(我相信这是一个常见的句子)。我正在编写一个优化服务器以成为网络服务器的脚本,我需要使用 powershell 写入 machine.configs。我也有所有需要的优化,我不需要帮助。

我一直在努力解决一个多月,还有很多谷歌搜索,我真的找不到解决方案,所以我想来找专家。希望我也能在 powershell 中变得更好,并在某些时候做出贡献。

到目前为止,我已经取得了令人难以置信的进展,并且已经完成了所有的优化和大部分的 powershell,但我被困在脚本的一部分

  1. 我需要得到机器有多少个cpu核心,我有这条线

    $property = "numberOfCores" Get-WmiObject -class win32_processor -Property $property | 选择对象-属性 $property

这告诉我我有多少个核心,这正是我需要的,但是一旦我有机器有多少个核心,我需要向 machine.config 写入一些值。

在 system.web 下,它有这些值

<system.web>
    <processModel autoConfig="true"/>

我需要用下面列出的这个值覆盖已经存在的值

<system.web>
    <processModel maxWorkerThreads="370" maxIoThreads="370" minWorkerThreads="50" minIoThreads="50"/>
<httpRuntime minFreeThreads="90" minLocalRequestFreeThreads="80"/>

除了在那里写那行(我不知道该怎么做)之外,我需要将 minfreethreads 乘以 CPU 内核的数量,并将该值写在 90 的位置,对于 minLocalRequestFreeThreads 80 也是如此

因此,例如,如果计算看到 2 个核心,它将编写以下行

<processModel maxWorkerThreads="370" maxIoThreads="370" minWorkerThreads="50" minIoThreads="50"/>
<httpRuntime minFreeThreads="180" minLocalRequestFreeThreads="160"/>

之后,我需要添加

<system.net>
<connectionManagement>
<add address = "*" maxconnection = "200" />
</connectionManagement>
</system.net>

和之前一样,然后将200替换为cpu cores和200的乘积值。希望不要问太多,我不知道如何写入xml文件,然后也乘以cores并取那个值并在那里添加?

所以它会喜欢这个

<system.net>
<connectionManagement>
<add address = "*" maxconnection = "400" />
</connectionManagement>
</system.net>

谁能帮我一把?

这是我到目前为止的代码,我很远,我正在逐行处理它,所以有些东西可能行不通,但我认为我走在正确的道路上

$xml = New-Object XML
$xml.Load("C:\Windows\Microsoft.NET\Framework\v2.0.50727\CONFIG\machine.config")
$Path = "C:\Windows\Microsoft.Net\Framework\V2.0.50727\config"
$File = "machine.config"
$current_path = $path + "\" + $file
$text = (get-content ($current_path))
$xml = [XML] (get-content ($current_path))
$p.RemoveAttribute("autoConfig")
$p = $xml.configuration."system.web".processModel
$p.SetAttribute("maxWorkerThreads", "370")
$p.SetAttribute("maxIoThreads", "370")
$p.SetAttribute("minWorkerThreads", "50")
$p = $xml.configuration."system.web".httpRunTime
$p.SetAttribute("minFreeThreads", "90")
$p.SetAttribute("minLocalRequestFreeThreads", "80")
$processor = (Get-CimInstance Win32_processor -Property NumberOfLogicalProcessors | Select -ExpandProperty "NumberOfLogicalProcessors")
$minFT = $processor * 90
$minFT = [string]$minFT
$minFT * 2
$p.SetAttribute("minFreeThreads", [string]$minFT)

$xml_content = [xml]@'
  <system.net>
    <connectionManagement>
      <add address = "*" maxconnection = "200" />
    </connectionManagement>
  </system.net>

Havent 经常使用 XML 和 PowerShell,但这似乎可以满足您的需求。将文件加载为 XML。删除有问题的两个元素,以便我们可以根据需要构建它们。最后我们在配置元素下添加元素和相应的细节。

如果在提交之前将值相乘,您将看到几个涵盖该内容的乘法实例。在您的示例中,您正在对一个简单地复制它的字符串执行乘法运算。考虑以下两个示例。

PS C:\Users\mcameron> "200" * 2
200200

PS C:\Users\mcameron> 200 * 2
400

更改您认为合适的路径。你会在最后看到我写到一个临时位置。我敦促您为测试做同样的事情。

$numberOfCores = Get-WmiObject -class win32_processor numberOfCores | Select-Object -ExpandProperty numberOfCores


$path = "C:\Windows\Microsoft.NET\Framework64\v4.0.30319\Config\machineTest.config"
[xml]$machineConfig = Get-Content $path

# Remove the elements we are going to be replacing
$node = $machineConfig.SelectNodes("/configuration/system.web") 
$node.RemoveChild(($node.SelectSingleNode("processModel"))) | Out-Null

# Create the element processModel and set attributes
$processModelxml = $machineConfig.CreateElement("processModel")
$processModelxml.setAttribute("maxWorkerThreads",370)
$processModelxml.setAttribute("maxWorkerThreads",370)
$processModelxml.setAttribute("maxIoThreads",370)
$processModelxml.setAttribute("minWorkerThreads",50)
$processModelxml.setAttribute("minIoThreads",50)
$node.AppendChild($processModelxml) | Out-Null

# Create the element httpRuntime and set attributes. Adjust values based on number of cores
$httpRuntimexml = $machineConfig.CreateElement("httpRuntime")
$httpRuntimexml.setAttribute("minFreeThreads",(90 * $numberOfCores))
$httpRuntimexml.setAttribute("minLocalRequestFreeThreads",(80 * $numberOfCores))
$node.AppendChild($httpRuntimexml) | Out-Null

# Build the <system.net> section
[xml]$systemnetxml = @"
  <system.net>
    <connectionManagement>
      <add address = "*" maxconnection = "$(200 * $numberOfCores)" />
    </connectionManagement>
  </system.net>
"@

# Import into config
$machineConfig.configuration.AppendChild($machineConfig.ImportNode($systemnetxml."system.net",$true)) | Out-Null

# Save changes
$machineConfig.Save("c:\temp\testing.xml")
# Change back to $path to write back to original file.

您还将看到Out-Null哪个可以抑制正在创建的元素的输出。它不会改变文件发生的情况。
