一、启用远程管理1、将管理服务器的trusthost列表改为*
运行Set-item wsman:localhostclient rustedhosts –value *
2、在远程服务器上运行Enable-PSremoting
注:在本地服务器上以Administrator运行“Enable-Psremoting 、 Winrm Quickconfig 、 Set-WSManQuickConfig”,均提示“访问被拒绝”,可能的原因如下:
1.在工作组计算机上,确认组策略: secpol.msc > Local Policies > Security Options > Network Access: Sharing and security model for local accounts - change to classic
2.修改注册表:
Set-ItemProperty –Path HKLM:SOFTWAREMicrosoftWindowsCurrentVersionPoliciesSystem –Name LocalAccountTokenFilterPolicy –Value 1 –Type DWord3.确认WinRM服务是否正在运行,Windows Firewall服务是否正在运行,网络位置是否不是“公用”,如果要启用PS远程管理,此时网络位置不能被设置为public,因为Windows 防火墙例外不能在网络位置是public时被启用。
4.Telnet localhost 47001是否可以连通
5.运行 winrm get winrm/config 是否会提示“访问被拒绝”
6.Administrator密码不能为空
远程启用开启之后可以在cmd命令窗口输入wbemtest测试是否可以连接远程服务器,如图:

连接成功的状态如下所示:

下面就可以来取每个服务器的磁盘空间了
二、脚本$server = "."$uid = "sa"$db="master"$pwd="数据库sa密码"$mailprfname = "test" ---需要跟select name FROM msdb.dbo .sysmail_profile一致$recipients = "接收邮箱,多个用;隔开" $subject = "邮件标题"$computernamexml = "E:powershellcomputername.xml"$alter_xml = "E:powershellcpdisk.xml"$pwd_xml = "E:powershellpwd.xml"function GetServerName($xmlpath){$xml = [xml] (Get-Content $xmlpath)$return = New-Object Collections.Generic.List[string]for($i = 0;$i -lt $xml.computernames.ChildNodes.Count;$i++){if ( $xml.computernames.ChildNodes.Count -eq 1){$cp = [string]$xml.computernames.computername}else{$cp = [string]$xml.computernames.computername[$i]}$return.Add($cp.Trim())}$return}function GetAlterCounter($xmlpath){$xml = [xml] (Get-Content $xmlpath)$return = New-Object Collections.Generic.List[string]$list = $xml.counters.Counter$list}function Getpwd($xmlpath){$xml = [xml] (Get-Content $xmlpath)$returnpwd = New-Object Collections.Generic.List[string]for($i = 0;$i -lt $xml.pwd.ChildNodes.Count;$i++){if ( $xml.pwds.ChildNodes.Count -eq 1){$pw = [string]$xml.pwd.password}else{$pw = [string]$xml.pwd.password[$i]}$returnpwd.Add($pw.Trim())}$returnpwd}function CreateAlter($message){$SqlConnection = New-Object System.Data.SqlClient.SqlConnection $CnnString ="Server = $server; Database = $db;User Id = $uid; Password = $pwd"$SqlConnection.ConnectionString = $CnnString $CC = $SqlConnection.CreateCommand(); if (-not ($SqlConnection.State -like "Open")) { $SqlConnection.Open() } $cc.CommandText=" EXEC msdb..sp_send_dbmail@profile_name = "$mailprfname",@recipients = "$recipients",@body = "$message",@subject = "$subject""$cc.ExecuteNonQuery()|out-null $SqlConnection.Close();}$names = GetServerName($computernamexml)$pfcounters = GetAlterCounter($alter_xml)$upwd = Getpwd($pwd_xml)$report = ""for($m=0;$m -lt $names.count;$m++){$cp=$names[$m]$p=New-Object -TypeName System.Collections.ArrayList$uname="administrator"--因为取的服务器用户名都是administrator,如果每台机器不一样,可以放在XML等文件中读取$pw=$upwd[$m]$upassword=convertto-securestring $pw -AsplainText -force;foreach ($pfc in $pfcounters){$filter="deviceID=""+$pfc.get_InnerText().Trim()+""" #$Disk =get-wmiobject win32_logicaldisk -computername $cp -Filter $filter#$counter=$Disk.Freespace/1024MB$cred=new-object system.management.automation.PSCredential($uname,$upassword);$counter=(get-wmiobject -credential $cred -class win32_logicaldisk -computername $cp -filter $filter).Freespace/1024MB$total=(get-wmiobject -credential $cred -class win32_logicaldisk -computername $cp -filter $filter).Size/1024MB#$pfc = $pfcounters[$i]$path = "机器名:"+$cp+"; 盘符:"+$pfc.get_InnerText()$diskFree=";总磁盘空间大小为:"+[math]::truncate($total).ToString()+"G;当前剩余空间大小为:"+[math]::truncate($counter).ToString()+"G!"$item = "{0} {1} " -f $path,$diskFree$report += $item + "`n"} }$reportif($report -ne ""){CreateAlter $report}
效果:

附:
xml文件格式:
1、computername.xml
<computername><computername>test</computername></computernames>
2、cpdisk.xml
<Counters><Counter>C:</Counter><Counter>D:</Counter></Counters>
3、pwd.xml
<pwd><password> helloworld </password><pwd>
完毕,欢迎拍砖!大笑
