之前線上伺服器分發配置都是用shell和expect指令碼分發，指令碼寫了很長，上週換了ansible，現在自己用python寫一個，就30行程式碼就可以實現需求，之前的shell寫了快200行了，蛋疼，程式碼如下：

from multiprocessing import Process

import paramiko

import sys

file = sys.argv[1]

Username = "root"

Password = "123456"

Dest_Path = [

    "/data/x5online/%s" %file,

    "/tmp/%s" %file

]

Port = 22

def sftpPut(ip):

    try:

        s = paramiko.Transport((ip,Port))

        s.connect(username=Username,password=Password)

        sftp = paramiko.SFTPClient.from_transport(s)

        localFile = file

        for remoteFile in Dest_Path:

            sftp.put(localFile,remoteFile)

        print("%s put successful." %ip)

    except:

        print("%s not exits."%ip)

def ipProcess():

    for i in range(10,40):

        ip = '192.168.170.%s'%i

        p = Process(target=sftpPut,args=(ip,))

        p.start()

if __name__ == '__main__':

    ipProcess()

雞湯一回，對python感興趣了，學的才快。
