修改Powershell脚本以针对多个不同的计算机目标执行

如何解决修改Powershell脚本以针对多个不同的计算机目标执行

我需要修改以下脚本，以便可以对所有DFS服务器成员或多个服务器执行该脚本，而不是手动RDP插入每个服务器然后执行此脚本。

现有脚本在$ComputerName = $env:ComputerName时有效，但在目标服务器为多个时无效。

脚本的用途：检查并报告DFS文件服务器复制的积压。如果导出的结果也为as.CSV文件，那就太好了，这样就可以根据服务器名称对其进行排序了。

Param (
    [String[]]$ReplicationGroupList = ("")
)

$RGroups = Get-WmiObject  -Namespace "root\MicrosoftDFS" -Query "SELECT * FROM DfsrReplicationGroupConfig"
#If replication groups specified,use only those.
if ($ReplicationGroupList) {
    $SelectedRGroups = @()
    foreach ($ReplicationGroup IN $ReplicationGroupList) {
        $SelectedRGroups += $rgroups | Where-Object { $_.ReplicationGroupName -eq $ReplicationGroup }
    }
    if ($SelectedRGroups.count -eq 0) {
        Write-Error "None of the group names specified were found,exiting"
        exit
    }
    else {
        $RGroups = $SelectedRGroups
    }
}

解决方法

假设WinRM已在环境中配置，则无需修改脚本-只需使用Invoke-Command在远程目标上按原样执行脚本即可：

$RemoteDFSServers = "dfs01","dfs2","dfs3"

Invoke-Command -FilePath C:\path\to\existing\script.ps1 -ComputerName $RemoteDFSServers
