Powershell 的自己主动部署



工作中反复性的版本号移植，一天上线10几次，让我痛不欲生，频繁的操作也可能出现疲劳性失误，导致严重的生产故障。于是乎，闲暇时间。我開始研究使用powershell自己主动部署程序到Linuxserver。

脚本中涉及到下面工具：

1、Wincp：借助其自身的命令行模式完毕程序部署

2、powershell的ssh-session模块。通过载入该模块连接到Linuxserver，运行相关shell命令

3、.net

開始上代码

#Public environment configure

$script:linuxPath="D:\test\newpath.txt"

$script:parentPath="D:\test\"

$script:parentPath2=$parentPath -replace "\\","/"

$script:projectConfigureFile="D:\test\projectConfigureFile.csv"

#运行shell函数

function Exec-Bash($computers,$user,$pwd,$linux_command){

    #Check SshSessions Module

    $modules=Get-Command -Module ssh-sessions

    if($modules -eq $null){

        Import-Module ssh-sessions

    }

    if($computers.GetType().IsArray){

        foreach($computer in $computers){

            $sshsession=Get-SshSession|?{$_.computername -eq $computer}

            if($sshsession.Connected -ne "true"){

                New-SshSession -ComputerName $computer -Username $user -Password $pwd -ErrorAction Stop

            }

            Invoke-SshCommand -ComputerName $computer -Quiet -Command $Linux_command

        }

    }else{

        $sshsession=Get-SshSession|?

{$_.computername -eq $computers}

        if($sshsession -eq $null){

            New-SshSession -ComputerName $computers -Username $user -Password $pwd -ErrorAction Stop

        }

        Invoke-SshCommand -ComputerName $computers -Quiet -Command $Linux_command

    }

    Remove-Item $linuxPath

}

#回收session函数

function Recycle-Session{

    param($computers)

    if($computers.GetType().IsArray){

        foreach($c in $computers){

            Remove-SshSession -ComputerName $c | out-null

        }

    }else{

        Remove-SshSession -ComputerName $computers | out-null

    }

}

#解密函数。主要用于解密server登录password

function Decrypt-String($Encrypted, $Passphrase, $salt="SaltCrypto", $init="IV_Password"){

    if($Encrypted -is [string]){

        $Encrypted = try{[Convert]::FromBase64String($Encrypted)}catch{return $false}

    }

    $r = new-Object System.Security.Cryptography.RijndaelManaged

    $pass = [Text.Encoding]::UTF8.GetBytes($Passphrase)

    $salt = [Text.Encoding]::UTF8.GetBytes($salt)

    $r.Key = (new-Object Security.Cryptography.PasswordDeriveBytes $pass, $salt, "SHA1", 5).GetBytes(32) #256/8

    $r.IV = (new-Object Security.Cryptography.SHA1Managed).ComputeHash( [Text.Encoding]::UTF8.GetBytes($init) )[0..15]

    $d = $r.CreateDecryptor()

    $ms = new-Object IO.MemoryStream @(,$Encrypted)

    $cs = new-Object Security.Cryptography.CryptoStream $ms,$d,"Read"

    $sr = new-Object IO.StreamReader $cs

    Write-Output $sr.ReadToEnd()

    $sr.Close()

    $cs.Close()

    $ms.Close()

    $r.Clear()

}

#在Windows环境下创建备份信息

function Creat-Path{

    Clear-Content $linuxPath -ErrorAction SilentlyContinue

    $toLinuxPath=dir -r $parentPath |%{$_.versioninfo}|select filename

    $n=""

    foreach($p in $toLinuxPath){

        $newPath=$p.filename -replace "\\","/"|%{$_ -replace $parentPath2,""}

        foreach($newP in $newPath){

            $n=$n +  ' ' + $newp

        }

    }

    $n=$n -replace 'newpath.txt',''

    $n > $linuxPath

    $n=""

}
