配置两台服务器之间3ssh-key后，可以实现自动化无需手动输入密码，脚本如下：

import argparse
import datetime
from functools import partial
import multiprocessing as mp
import os
import paramiko as pmk
import time

def check_ssh(host, user, port, passwd, dest_path):
  ssh_client = pmk.SSHClient()
  ssh_client.load_system_host_keys()
  ssh_client.set_missing_host_key_policy(pmk.AutoAddPolicy())
  try:
    ssh_client.connect(host, username=user, port=port, timeout=10, password=passwd)
    ssh_client.exec_command('mkdir ' + os.path.join(dest_path, 'data'))
  except BaseException as e:
    print 'failed to connect to host: %r: %r' % (host, e)
    return False
  else:
    return True

def select_from_file(file_path):
  file_list = []
  if os.path.exists(file_path):
    path_dir = os.listdir(file_path)
    for all_dir in path_dir:
      file_list.append(os.path.join('%s' % all_dir))
  return file_list

def sync_file(file_name, remote_host, remote_user, remote_port, src_path, dest_path):
  sync_cmd = "rsync -azrvhP --progress -e 'ssh -p " + str(remote_port) + "' --skip-compress=gz/zip/ " + \
        file_name + " " + remote_user + "@" + remote_host + ":" + os.path.join(dest_path,'data')
  print sync_cmd
  os.chdir(src_path)
  os.system(sync_cmd)

if __name__ == '__main__':
  parser = argparse.ArgumentParser()
  parser.add_argument('-w', '--workers', dest='workers', type=int, default=12)
  parser.add_argument('-H', '--host', dest='host', type=str, default='192.168.254.156')
  parser.add_argument('-u', '--user', dest='user', type=str, default='shubao')
  parser.add_argument('-p', '--password', dest='password', type=str, default='123456')
  parser.add_argument('-P', '--port', dest='port', type=int, default=22)
  parser.add_argument('-r', '--remotepath', dest='remotepath', type=str, default='/home/shubao/')
  parser.add_argument('-s', '--srcpath', dest='srcpath', type=str, default='/home/Jesse/data')
  args = parser.parse_args()
  if not check_ssh(args.host, args.user, args.port, args.password, args.remotepath):
    print 'SSH connect faild!'
    exit(-1)
  pool = mp.Pool(processes=args.workers)
  try:
    while True:
      print "New check start at %s..." % str(datetime.datetime.now())
      file_list_ = select_from_file(args.srcpath)
      print "File_list: "
      print file_list_
      p_work = partial(sync_file, remote_host=args.host, remote_user=args.user, remote_port=args.port,
               src_path=args.srcpath, dest_path=args.remotepath)
      pool.map(p_work, file_list_)
      time.sleep(10)
  finally:
    pool.terminate()
    pool.join()
