    sfbahr/PyCrypto-Wheels/raw/master/pycrypto-2.6.1-cp35-none-win_amd64.whl pycrypto
    2.pip3 install paramiko
    3.修改python解释器目录下的Libsite-packagesCryptoRandomOSRNG
t.py
    第28行
    import winrandom 修改成 from Crypto.Random.OSRNG import winrandom 

2.linux（centos）：

1.yum -y install gcc python-devel
2.安装pycrypto
     pip3 install pycrypto
3.安装paramiko
     pip3 install paramiko

paramiko模块，模块基于SSH用于连接远程服务器并执行相关操作

SSHClient

用于连接远程服务器并执行基本命令

基于用户名密码连接：

#!/bin/bin/env python
# -*-coding:utf-8 -*-
# Author : rain

import paramiko

# 创建ssh对象
ssh = paramiko.SSHClient()
# 允许连接不在Know_hosts文件中的主机
ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy())
# 连接服务器
ssh.connect(hostname='127.0.0.1', port=22, username='root', password='123')

# 执行命令(stdout：输出命令执行结果， stderr：输出命令执行中，报错信息)
stdin, stdout, stderr = ssh.exec_command('df -dfjd')

# 获取命令结果，正确结果
result = stdout.read()
print(result.decode())
# 获取命令结果，错误信息
reserr = stderr.read()
print(reserr)
# 关闭连接
ssh.close()

import paramiko

transport = paramiko.Transport(('hostname', 22))
transport.connect(username='root', password='passwd')

ssh = paramiko.SSHClient()
ssh._transport = transport

stdin, stdout, stderr = ssh.exec_command('df')
print(stdout.read().decode())

基于公钥密钥连接：

import paramiko
 
private_key = paramiko.RSAKey.from_private_key_file('/home/auto/.ssh/id_rsa')
 
# 创建SSH对象
ssh = paramiko.SSHClient()
# 允许连接不在know_hosts文件中的主机
ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy())
# 连接服务器
ssh.connect(hostname='10.10.33.11', port=22, username='root', pkey=private_key)
 
# 执行命令
stdin, stdout, stderr = ssh.exec_command('df')
# 获取命令结果
result = stdout.read()
 
# 关闭连接
ssh.close()

import paramiko

private_key = paramiko.RSAKey.from_private_key_file('/home/auto/.ssh/id_rsa')

transport = paramiko.Transport(('hostname', 22))
transport.connect(username='wupeiqi', pkey=private_key)

ssh = paramiko.SSHClient()
ssh._transport = transport

stdin, stdout, stderr = ssh.exec_command('df')

transport.close()

SFTPClient

用于连接远程服务器并执行上传下载

基于用户名密码上传下载

import paramiko
 
transport = paramiko.Transport(('hostname',22))
transport.connect(username='root',password='123')
 
sftp = paramiko.SFTPClient.from_transport(transport)
# 将location.py 上传至服务器 /tmp/test.py
sftp.put('/tmp/location.py', '/tmp/test.py')
# 将remove_path 下载到本地 local_path
sftp.get('remove_path', 'local_path')
 
transport.close()

基于公钥密钥上传下载

import paramiko
private_key = paramiko.RSAKey.from_private_key_file('/home/auto/.ssh/id_rsa')
transport = paramiko.Transport(('hostname', 22))
transport.connect(username='你的用户名', pkey=private_key )
sftp = paramiko.SFTPClient.from_transport(transport)
# 将你目录/本地文件 上传至服务器 目录/文件
sftp.put('/tmp/location.py', '/tmp/test.py')
# 将目标服务器文件 下载到本地 指定目录
sftp.get('remove_path', 'local_path')
# 关闭链接
transport.close()

#!/usr/bin/env python
# -*- coding:utf-8 -*-
