powershell 运行并行脚本

Question

我正在使用 windows 服务器 2003，现在我有一个脚本可以重新启动一项特定的服务，有人可以指导我如何并行运行这个脚本吗？我已经使用了 start-job，但在后台似乎只有运行但仍然是连续的，下面是我的脚本：

文件名：重启服务.ps1

$start = Get-Date
$Serverlist = Get-Content -path C:\Computers.txt

ForEach ($Server in $Serverlist){
start-job -scriptblock {param($Server) Restart-Service -InputObject $(Get-Service -ComputerName $Server -Name "aspnet_state")} -ArgumentList $Server
}
Get-Job | Wait-Job
Get-Job | Receive-Job
$end = Get-Date
$timespan = $end - $start
$seconds = $timespan.TotalSeconds
Write-Host "This took me $seconds seconds."

或这个

$start = Get-Date
$Server = Get-Content -path C:\Computers.txt

$scriptblock = {
    Param($Server)
    Restart-Service -InputObject $(Get-Service -ComputerName $Server -Name "aspnet_state")
}
$Server | % {Start-Job -Scriptblock $scriptblock -ArgumentList $_ | Out-Null}
Get-Job | Wait-Job | Receive-Job

$end = Get-Date
$timespan = $end - $start
$seconds = $timespan.TotalSeconds
Write-Host "This took me $seconds seconds."

但是我只能看到结果，但是看不到我服务器IP的任何结果相关信息，谁能帮我改进一下...

Answer 1

这是方向，根据您的具体需要对其进行调整...添加计时器等...

$Serverlist = Get-Content -path C:\Computers.txt

Foreach ($Server in $Serverlist)
{
    Start-Job -Name "$Server-Job" -ScriptBlock {
    Get-Service -ComputerName $args[0] -Name "aspnet_state" | Restart-Service 
    } -ArgumentList $Server
}

它将为每个服务器创建一个带有 ServerName 的作业，以获取作业 status/info，使用：

Get-Job | Receive-Job
