Powershell和Machine.config帮助
我对powershell很新,如果可能的话我需要一个快速的手(我确信这是一个常见的句子)。我正在编写一个优化服务器成为Web服务器的脚本,我需要使用powershell写入machine.configs。我也需要所有优化,我不需要帮助。
我一直在努力解决这个问题超过一个月,还有很多谷歌搜索,我真的找不到解决方案,所以我想找专家来。希望我也能在PowerShell中获得好处,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,但我仍然坚持脚本中的一部分
我需要知道机器有多少cpu核心,我有这条线
$ property =" numberOfCores" Get-WmiObject -class win32_processor -Property $ property | Select-Object -Propert $ property
这告诉我我有多少核心,这正是我需要的东西但是一旦我拥有机器有多少核心,我需要写入machine.config一些值。
在system.web下,它具有这些值
<system.web>
<processModel autoConfig="true"/>
我需要用下面列出的
覆盖已存在的值<system.web>
<processModel maxWorkerThreads="370" maxIoThreads="370" minWorkerThreads="50" minIoThreads="50"/>
<httpRuntime minFreeThreads="90" minLocalRequestFreeThreads="80"/>
除了在那里写那条线(我无法弄清楚怎么做)之外,我需要将minfreethreads乘以CPU核心数并将该值写入90的位置,并为minLocalRequestFreeThreads 80写入相同的值
因此,例如,如果计算看到2个核心,它将写入以下行
<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>
和以前一样,然后用cpu核心和200的乘积值替换200.我希望不要问太多,我不知道如何写入xml文件,以及然后还乘以核心并获取该值并将其添加到那里?
所以想要这个
<system.net>
<connectionManagement>
<add address = "*" maxconnection = "400" />
</connectionManagement>
</system.net>
任何人都可以帮我一把吗?

这是我到目前为止的代码,我很远,我正在逐行工作,所以有些事可能行不通但我觉得我走的是正确的道路

还没有玩过很多XML和PowerShell,但这似乎适用于你想要的东西。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。
如果值在提交之前成倍增加,您将看到几个覆盖范围的乘法实例。在你的例子中,你是一个字符串的执行乘法,它只是简单地重复它。请考虑以下两个示例。
PS C:\Users\mcameron> "200" * 2
200200
PS C:\Users\mcameron> 200 * 2
400
根据需要更改路径。最后我会看到我写到临时位置。我敦促你做同样的测试。
$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>

"@
# 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.
您还会看到Out-Null
,它可以抑制正在创建的元素的输出。它不会改变文件发生的变化。
