powersheel远程连接密码加密连接高级玩法
ConvertTo-SecureString 和 ConvertFrom-SecureString 命令都支持选项 -Key。在处理密码时通过使用 Key 选项可以提供额外的安全性,并且允许在不同的环境中使用密码文件。
先生成 32 位的 Key 并保存在文件 aes.key 中:
$keyFile = "C:\powersheel\aes.key" #加密的key准备放在这个D盘,最好放在一个文件夹里面 $key = New-Object Byte[] 32 [Security.Cryptography.RNGCryptoServiceProvider]::Create().GetBytes($key) $key | out-file $keyFile
使用 Key 生成并保存密码文件:
Read-Host "Enter Password" -AsSecureString | ConvertFrom-SecureString -key $key | Out-File "C:\powersheel\pwd.txt"
使用密码文件创建和 Key 文件创建 Credential 信息:
$userName = "YourUserName" $passwdFile = "C:\powersheel\pwd.txt" $keyFile = "C:\powersheel\aes.key" $key = Get-Content $keyFile $Cred = New-Object -TypeName System.Management.Automation.PSCredential ` -ArgumentList $userName, (Get-Content $passwdFile | ConvertTo-SecureString -Key $key)
通过这种方法,把 pwd.txt 和 aes.key 文件拷贝到其它的机器上也是可以工作的。但是我们需要额外维护一个 key 文件的安全,这一般通过设置文件的访问权限就可以了。
以上是将密码通过32位的key加密到文件里面,下面的第一个远程连接会用到
第1种方法远程连接(密码加密):
$userName = "administrator" $passwdFile = "C:\powersheel\pwd.txt" $keyFile = "C:\powersheel\AES.key" $key = Get-Content $keyFile $cred = New-Object -TypeName System.Management.Automation.PSCredential -ArgumentList $userName, (Get-Content $passwdFile | ConvertTo-SecureString -Key $key) $remoteServer='www.bai.com' #连接方法 function connRemoteSever { #连接远程服务器 Param ($remoteServer,$cred) #$passwordSecure = ConvertTo-SecureString $pwd -AsPlainText -Force #$cred = New-Object pscredential($userName, $passwordSecure) Write-Host '-----------powersheel默认Port是5985、5986-----------' $mySession = New-PSSession -ComputerName $remoteServer -Port 55985 -Credential $cred return $mySession } #连接到远程服务器 $webSession=connRemoteSever $remoteServer $cred Invoke-Command -Session $webSession -ScriptBlock { dir d: Write-Host '-----------1.在覆盖网站内容前,先停止网站-----------' #Import-Module WebAdministration; Stop-WebAppPool -Name "$appPoolName" #Import-Module WebAdministration; Stop-WebSite -Name "$appWebSiteName" Write-Host '-----------2.备份IIS中绩效的网站-----------' #Copy-Item -Path "D:\web\kpi_dev" "D:\web\Backup\kpi_dev_$backtime" -Recurse -Force Write-Host '-----------3.删除IIS绩效后端-----------' #Remove-Item -Path $DelFilePath -Recurse -Force Write-Host '-----------4.复制最新绩效后端到IIS发布的文件夹-----------' #Copy-Item -Path "D:\web\WebFTP\publish_kpi_BackEnd_dev\$banben\*" "D:\web\kpi_dev\BackEnd\" -Recurse -Force Write-Host '-----------5.复制web.config到IIS发布的文件夹-----------' #Copy-Item -Path "D:\web\kpi_dev\web.config" "D:\web\kpi_dev\BackEnd\" -Recurse -Force Write-Host '-----------6.启动网站-----------' #Import-Module WebAdministration; Start-WebAppPool -Name "$appPoolName" #Import-Module WebAdministration; Start-WebSite -Name "$appWebSiteName" }
第2种方法远程连接(密码不加密):
$userName = 'opsadmin'$pwd = 'ywX*'$remoteServer='192.168.0.100'function connRemoteSever { # 连接远程服务器 Param ($userName,$pwd,$remoteServer,$port) #参数 $passwordSecure = ConvertTo-SecureString $pwd -AsPlainText -Force $cred = New-Object pscredential($userName, $passwordSecure) $mySession = New-PSSession -ComputerName $remoteServer -Port 5985 -Credential $cred return $mySession}# 连接到远程服务器$webSession=connRemoteSever $pwd $userName $remoteServer$banben='V'+$env:BUILD_NUMBER #这边是在windows中的jenkins中使用到的$backtime=Get-Date -Format 'yyyy_M_d_Hms'$DelFilePath='D:\web\kpi_dev\BackEnd\*'$DelFileExcludePath='D:\web\kpi_dev\BackEnd\wwwroot*'$appPoolName='kpi_dev'$appWebSiteName='kpi_dev'Invoke-Command -Session $webSession -ScriptBlock { param($appPoolName,$appWebSiteName,$backtime,$DelFilePath,$banben)#以下都是一些操作都是一些基本操作命令,大家有用到的话借鉴下dir d:Write-Host '-----------1.在覆盖网站内容前,先停止网站-----------'#Import-Module WebAdministration; Stop-WebAppPool -Name "$appPoolName"#Import-Module WebAdministration; Stop-WebSite -Name "$appWebSiteName"Write-Host '-----------2.备份IIS中绩效的网站-----------'#Copy-Item -Path "D:\web\kpi_dev" "D:\web\Backup\kpi_dev_$backtime" -Recurse -ForceWrite-Host '-----------3.删除D:\web\kpi_dev\BackEnd 文件夹下除了wwwroot文件夹,其他的全删除-----------'#Remove-Item -Path $DelFilePath -Recurse -ForceGet-ChildItem -Path $DelFilePath -Recurse -exclude wwwroot | Select -ExpandProperty FullName |Where {$_ -notlike $DelFileExcludePath} |sort length -Descending |Remove-Item -forceWrite-Host '-----------4.复制最新绩效后端到IIS发布的文件夹-----------'#Copy-Item -Path "D:\web\WebFTP\publish_kpi_BackEnd_dev\$banben\*" "D:\web\kpi_dev\BackEnd\" -Recurse -ForceWrite-Host '-----------5.复制web.config到IIS发布的文件夹-----------'#Copy-Item -Path "D:\web\kpi_dev\web.config" "D:\web\kpi_dev\BackEnd\" -Recurse -ForceWrite-Host '-----------6.启动网站-----------'#Import-Module WebAdministration; Start-WebAppPool -Name "$appPoolName"#Import-Module WebAdministration; Start-WebSite -Name "$appWebSiteName"} -ArgumentList $appPoolName,$appWebSiteName,$backtime,$DelFilePath,$banben
第3种方法远程连接:
$Username = 'opsadmin' #远程电脑的用户名$Password = 'ywX*^R' #远程电脑的密码$pass = ConvertTo-SecureString -AsPlainText $Password -Force$Cred = New-Object System.Management.Automation.PSCredential -ArgumentList $Username,$passInvoke-Command -ComputerName 192.168.0.100 -Port 5985 -ScriptBlock { dir D:\web\Backup #查看当前远程服务器这个文件夹下得目录列表情况 } -credential $Cred
