python第三方模块之paramiko模块

一、paramiko模块介绍

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。它包含两个常用模块，SSHClient()模块，SFTPClient()模块。

二、paramiko模块安装

pycrypto，由于 paramiko 模块内部依赖pycrypto，所以先下载安装pycrypto
pip3 install pycrypto
pip3 install paramiko

三、paramiko模块使用

1、执行远程命令SSHClient()模块

#!/usr/bin/python

import paramiko

 

ssh = paramiko.SSHClient()

ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy())

ssh.connect("某IP地址",22,"用户名", "口令")

stdin, stdout, stderr = ssh.exec_command("你的命令")

print stdout.readlines()

ssh.close()

2、执行远程命令SSHClient()模块之密钥登录

import paramiko

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

ssh = paramiko.SSHClient()
ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy())
ssh.connect('主机名 ', 端口, '用户名', key)

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

import paramiko

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

t = paramiko.Transport(('182.92.219.86',22))
t.connect(username='wupeiqi',pkey=key)

sftp = paramiko.SFTPClient.from_transport(t)
sftp.put('/tmp/test3.py','/tmp/test3.py')

t.close()

import paramiko

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

t = paramiko.Transport(('182.92.219.86',22))
t.connect(username='wupeiqi',pkey=key)

sftp = paramiko.SFTPClient.from_transport(t)
sftp.get('/tmp/test3.py','/tmp/test4.py')

t.close()

3、上传文件到远程SFTPClient()模块

#!/usr/bin/python

import paramiko

 

t = paramiko.Transport(("某IP地址",22))

t.connect(username = "用户名", password = "口令")

sftp = paramiko.SFTPClient.from_transport(t)

remotepath='/tmp/test.txt'

localpath='/tmp/test.txt'

sftp.put(localpath,remotepath)

t.close()

4、远程下载到本地SFTPClient()模块

import paramiko

 

t = paramiko.Transport(("某IP地址",22))

t.connect(username = "用户名", password = "口令")

sftp = paramiko.SFTPClient.from_transport(t)

remotepath='/tmp/test.txt'

localpath='/tmp/test.txt'

sftp.get(remotepath, localpath)

t.close()

5、整合使用：

#coding:utf-8
import paramiko
import uuid

class SSHConnection(object):

    def __init__(self, host='192.168.2.103', port=22, username='root',pwd='123456'):
        self.host = host
        self.port = port
        self.username = username
        self.pwd = pwd
        self.__k = None

    def connect(self):
        transport = paramiko.Transport((self.host,self.port))
        transport.connect(username=self.username,password=self.pwd)
        self.__transport = transport

    def close(self):
        self.__transport.close()

    def upload(self,local_path,target_path):
        # 连接，上传
        # file_name = self.create_file()
        sftp = paramiko.SFTPClient.from_transport(self.__transport)
        # 将location.py 上传至服务器 /tmp/test.py
        sftp.put(local_path, target_path)

    def download(self,remote_path,local_path):
        sftp = paramiko.SFTPClient.from_transport(self.__transport)
        sftp.get(remote_path,local_path)

    def cmd(self, command):
        ssh = paramiko.SSHClient()
        ssh._transport = self.__transport
        # 执行命令
        stdin, stdout, stderr = ssh.exec_command(command)
        # 获取命令结果
        result = stdout.read()
        print (str(result,encoding='utf-8'))
        return result

ssh = SSHConnection()
ssh.connect()
ssh.cmd("ls")
ssh.upload('s1.py','/tmp/ks77.py')
ssh.download('/tmp/test.py','kkkk',)
ssh.cmd("df")
ssh.close()
