通过Powershell运行远程命令

Question

我试图通过脚本在一系列远程系统上调用离散的命令行界面命令，但是我无法获得任何接受它们的PowerShell命令。我不会试图解释这个问题的细节，而是在下面提供一些我试图做的伪代码。

请注意，这只是一个简单的示例。不能使用stop-service命令。这些是通过CLI通过Splunk程序使用的显式命令，我需要按此顺序运行这些命令。

简而言之，我只是想不出如何告诉PowerShell在远程机器上逐字运行CLI命令。

foreach ($server in $list)
     cd C:\Program Files\SplunkUniversalForwarder\bin
     splunk stop
     splunk clone-prep-clear-config
     splunk start

Answer 1

有很多方法可以做到这一点。使用WMI c/o Powershell：

Starting,Stopping and Restarting Remote Services with PowerShell

您也可以使用Windows remoting，但我将从这里开始。

Answer 2

你可以试试..。

Foreach($server in $list)
{
    Invoke-command -computername $server -scripblock {
        $splunkpath = 'c:\program files\splunkuniversalforwarder\bin\splunk.exe'
        Start-process -filepath $splunkpath -argumentlist 'stop' -wait -nonewwindow
        Start-process -filepath $splunkpath -argumentlist 'clone-prep-clear-config' -wait -nonewwindow
        Start-process -filepath $splunkpath -argumentlist 'start' -wait -nonewwindow
    }
}

注意:根据进程的行为，您可能需要从命令中删除-wait和/或-nonewwindow。

还有输出重定向参数，请查看下面的文档以了解更多信息。

Invoke-command

Start-process

Answer 3

我今天早上就这么做了。这是我想出的主要部分。

foreach($server in $servers){
Write-Host "From " -nonewline; Write-Host "$server" -ForegroundColor Yellow
Invoke-Command -ComputerName $server -ScriptBlock { C:\SplunkUniversalForwarder\bin\splunk.exe stop } -Credential $cred
Invoke-Command -ComputerName $server -ScriptBlock { C:\SplunkUniversalForwarder\bin\splunk.exe clone-prep-clear-config } -Credential $cred
Invoke-Command -ComputerName $server -ScriptBlock { C:\SplunkUniversalForwarder\bin\splunk.exe start } -Credential $cred

}

我的完整代码如下：

#Author: Christopher Boillot
#Clear config of Splunk Forwarder



[CmdletBinding()]
Param ([Parameter(Mandatory=$False,Position=0)]
         [String[]]$servers = (Get-Content C:\ClearConfig.txt))


Set-Location $PSScriptRoot

#User login
$User = "user.txt" 
$FileExists = Test-Path $User 
If ($FileExists -eq $False) {
Write-Host "Enter your user name. This will be saved as  $User"
read-host | out-file $User
}
$Pass = "securepass.txt" 
$FileExists = Test-Path $Pass 
If ($FileExists -eq $False) {
Write-Host "Enter your password. This will be saved as an encrypted sting as $Pass"
read-host -assecurestring | convertfrom-securestring | out-file $Pass
}

$username = cat $User
$password = cat $Pass | convertto-securestring
$cred = new-object -typename System.Management.Automation.PSCredential `
         -argumentlist $username, $password


#go through each server in list
foreach($server in $servers){



Write-Host "From " -nonewline; Write-Host "$server" -ForegroundColor Yellow
Invoke-Command -ComputerName $server -ScriptBlock { C:\SplunkUniversalForwarder\bin\splunk.exe stop } -Credential $cred
Invoke-Command -ComputerName $server -ScriptBlock { C:\SplunkUniversalForwarder\bin\splunk.exe clone-prep-clear-config } -Credential $cred
Invoke-Command -ComputerName $server -ScriptBlock { C:\SplunkUniversalForwarder\bin\splunk.exe start } -Credential $cred

}
