paramiko是一个用于做远程控制的模块，使用该模块可以对远程服务器进行命令或文件操作，值得一说的是，fabric和ansible内部的远程管理就是使用的paramiko来现实。
pip install paramiko#!/usr/bin/env python
#coding:utf-8
import paramiko
# 建立一个sshclient对象
ssh = paramiko.SSHClient()
# 允许将信任的主机自动加入到host_allow 列表，此方法必须放在connect方法的前面
ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy())
# 调用connect方法连接服务器
ssh.connect('192.168.1.108', 22, 'alex', '123')
# 执行命令
stdin, stdout, stderr = ssh.exec_command('df')
# 结果放到stdout中，如果有错误将放到stderr中
print(stdout.read().decode('utf-8'))
# 关闭连接

删掉cryptography，安装2.4.2，就不会报错了。
