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

Clear-Content $linuxPath -ErrorAction SilentlyContinue
$toLinuxPath=dir -r $parentPath |%{$_.versioninfo}|select filename
$n=""
foreach($p in $toLinuxPath){
