powershell遠程管理服務器磁盤空間的實現代碼

時間：2020-01-28來源：系統城作者：電腦系統城

一、啟用遠程管理

1、將管理服務器的trusthost列表改為*

運行Set-item wsman:localhost\client\trustedhosts –value *

2、在遠程服務器上運行Enable-PSremoting

注：

在本地服務器上以Administrator運行“Enable-Psremoting 、 Winrm Quickconfig 、 Set-WSManQuickConfig”，均提示“訪問被拒絕”，可能的原因如下：

1.在工作組計算機上，確認組策略： secpol.msc > Local Policies > Security Options > Network Access: Sharing and security model for local accounts - change to classic
2.修改注冊表：Set-ItemProperty –Path HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\System –Name LocalAccountTokenFilterPolicy –Value 1 –Type DWord
3.確認WinRM服務是否正在運行，Windows Firewall服務是否正在運行，網絡位置是否不是“公用”，如果要啟用PS遠程管理，此時網絡位置不能被設置為public，因為Windows 防火墻例外不能在網絡位置是public時被啟用。
4.Telnet localhost 47001是否可以連通
5.運行 winrm get winrm/config 是否會提示“訪問被拒絕”
6.Administrator密碼不能為空

遠程啟用開啟之后可以在cmd命令窗口輸入wbemtest測試是否可以連接遠程服務器，如圖：

連接成功的狀態如下所示：

下面就可以來取每個服務器的磁盤空間了

二、腳本

$server = "."
$uid = "sa"
$db="master"

}
else
{

$return.Add($cp.Trim())
}
$return

$cc.ExecuteNonQuery()|out-null

$item = "{0} {1} " -f $path,$diskFree
$report += $item + "`n"
