使用 Powershell 在多台服务器上设置电源计划

Question

我想在多台服务器上设置 "High Performance" 电源计划。我有以下脚本，当我在服务器上一个一个地执行它时，它运行很好。

Set-PowerPlan "High performance"

function Set-PowerPlan {

[CmdletBinding(SupportsShouldProcess = $True)]

param (

    [ValidateSet("High performance", "Balanced", "Power saver")]

    [ValidateNotNullOrEmpty()]

    [string] $PreferredPlan = "High Performance"
      )

Write-Host "Setting power plan to `"$PreferredPlan`""

$guid = (Get-WmiObject -Class Win32_PowerPlan -Namespace root\cimv2\power -Filter "ElementName='$PreferredPlan'").InstanceID.ToString()

$regex = [regex]"{(.*?)}$"

$plan = $regex.Match($guid).groups[1].value

powercfg -S $plan

$Output = "Power plan set to "

$Output += "`"" + ((Get-WmiObject -Class Win32_PowerPlan -Namespace root\cimv2\power -Filter "IsActive='$True'").ElementName) + "`""

 Write-Host $Output
}

如何将服务器列表传递给此脚本，以便递归地在所有服务器上设置电源计划？

Answer 1

您必须按照以下建议对脚本进行更改：

[CmdletBinding(SupportsShouldProcess = $True)]
param (

    [ValidateSet("High performance", "Balanced", "Power saver")]

    [ValidateNotNullOrEmpty()]

    [string] $PreferredPlan = "High Performance"
      )

Write-Host "Setting power plan to `"$PreferredPlan`""

$guid = (Get-WmiObject -Class Win32_PowerPlan -Namespace root\cimv2\power -Filter "ElementName='$PreferredPlan'").InstanceID.ToString()

$regex = [regex]"{(.*?)}$"

$plan = $regex.Match($guid).groups[1].value

powercfg -S $plan

$Output = "Power plan set to "

$Output += "`"" + ((Get-WmiObject -Class Win32_PowerPlan -Namespace root\cimv2\power -Filter "IsActive='$True'").ElementName) + "`""

 Write-Host $Output

并使用此命令定位多个服务器：

Invoke-Command -FilePath .\Set-PowerPlan.ps1 -ComputerName (Get-Content -Path C:\temp\computers.txt)

其中 Computers.txt 将使用换行符分隔服务器名称。

只需将 computername 参数添加到您的函数中，并在其中添加 Get-WmiObject。我还使用 this solution 远程启动进程。

function Set-PowerPlan {

    [CmdletBinding(SupportsShouldProcess = $True)]
    param (

        [ValidateSet("High performance", "Balanced", "Power saver")]
        [ValidateNotNullOrEmpty()]
        [string]$PreferredPlan = "High Performance",
        [string]$ComputerName = $env:COMPUTERNAME
    )

    Write-Host "Setting power plan to `"$PreferredPlan`""

    $guid = (Get-WmiObject -Class Win32_PowerPlan -Namespace root\cimv2\power -Filter "ElementName='$PreferredPlan'" -ComputerName $ComputerName).InstanceID.ToString()

    $regex = [regex]"{(.*?)}$"

    $plan = $regex.Match($guid).groups[1].value

    #powercfg -S $plan
    $process = Get-WmiObject -Query "SELECT * FROM Meta_Class WHERE __Class = 'Win32_Process'" -Namespace "root\cimv2" -ComputerName $ComputerName
    $results = $process.Create("powercfg -S $plan")

    $Output = "Power plan set to "
    $Output += "`"" + ((Get-WmiObject -Class Win32_PowerPlan -Namespace root\cimv2\power -Filter "IsActive='$True'" -ComputerName $ComputerName).ElementName) + "`""

    Write-Host $Output
}

$ServerList = @(
    'CompName1',
    'Compname2'
)

foreach ($server in $ServerList ) {
    Set-PowerPlan -PreferredPlan 'High performance' -ComputerName $comp
}
