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

 1 #!/usr/bin/python
  2
  3 import paramiko
  4
  5
  6
  7 ssh = paramiko.SSHClient()
  8
  9 ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy())
 10
 11 ssh.connect("某IP地址",22,"用户名", "口令")
 12
 13 stdin, stdout, stderr = ssh.exec_command("你的命令")
 14
 15 print stdout.readlines()
 16
 17 ssh.close()

2、执行远程命令SSHClient()模块之密钥登录

  1 import paramiko
  2
  3 private_key_path = '/home/auto/.ssh/id_rsa'
  4 key = paramiko.RSAKey.from_private_key_file(private_key_path)
  5
  6 ssh = paramiko.SSHClient()
  7 ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy())
  8 ssh.connect('主机名 ', 端口, '用户名', key)
  9
 10 stdin, stdout, stderr = ssh.exec_command('df')
 11 print stdout.read()
 12 ssh.close()

 1 import paramiko
  2
  3 pravie_key_path = '/home/auto/.ssh/id_rsa'
  4 key = paramiko.RSAKey.from_private_key_file(pravie_key_path)
  5
  6 t = paramiko.Transport(('182.92.219.86',22))
  7 t.connect(username='wupeiqi',pkey=key)
  8
  9 sftp = paramiko.SFTPClient.from_transport(t)
 10 sftp.put('/tmp/test3.py','/tmp/test3.py')
 11
 12 t.close()
 13
 14 import paramiko
 15
 16 pravie_key_path = '/home/auto/.ssh/id_rsa'
 17 key = paramiko.RSAKey.from_private_key_file(pravie_key_path)
 18
 19 t = paramiko.Transport(('182.92.219.86',22))
 20 t.connect(username='wupeiqi',pkey=key)
 21
 22 sftp = paramiko.SFTPClient.from_transport(t)
 23 sftp.get('/tmp/test3.py','/tmp/test4.py')
 24
 25 t.close()

3、上传文件到远程SFTPClient()模块

1 #!/usr/bin/python
 2
 3 import paramiko
 4
 5
 6
 7 t = paramiko.Transport(("某IP地址",22))
 8
 9 t.connect(username = "用户名", password = "口令")
10
11 sftp = paramiko.SFTPClient.from_transport(t)
12
13 remotepath='/tmp/test.txt'
14
15 localpath='/tmp/test.txt'
16
17 sftp.put(localpath,remotepath)
18
19 t.close()

4、远程下载到本地SFTPClient()模块

 1 import paramiko
 2
 3
 4
 5 t = paramiko.Transport(("某IP地址",22))
 6
 7 t.connect(username = "用户名", password = "口令")
 8
 9 sftp = paramiko.SFTPClient.from_transport(t)
10
11 remotepath='/tmp/test.txt'
12
13 localpath='/tmp/test.txt'
14
15 sftp.get(remotepath, localpath)
16
17 t.close()

5、整合使用：

  1 #coding:utf-8
  2 import paramiko
  3 import uuid
  4
  5 class SSHConnection(object):
  6
  7     def __init__(self, host='192.168.2.103', port=22, username='root',pwd=''):
  8         self.host = host
  9         self.port = port
 10         self.username = username
 11         self.pwd = pwd
 12         self.__k = None
 13
 14     def connect(self):
 15         transport = paramiko.Transport((self.host,self.port))
 16         transport.connect(username=self.username,password=self.pwd)
 17         self.__transport = transport
 18
 19     def close(self):
 20         self.__transport.close()
 21
 22     def upload(self,local_path,target_path):
 23         # 连接，上传
 24         # file_name = self.create_file()
 25         sftp = paramiko.SFTPClient.from_transport(self.__transport)
 26         # 将location.py 上传至服务器 /tmp/test.py
 27         sftp.put(local_path, target_path)
 28
 29     def download(self,remote_path,local_path):
 30         sftp = paramiko.SFTPClient.from_transport(self.__transport)
 31         sftp.get(remote_path,local_path)
 32
 33     def cmd(self, command):
 34         ssh = paramiko.SSHClient()
 35         ssh._transport = self.__transport
 36         # 执行命令
 37         stdin, stdout, stderr = ssh.exec_command(command)
 38         # 获取命令结果
 39         result = stdout.read()
 40         print (str(result,encoding='utf-8'))
 41         return result
 42
 43 ssh = SSHConnection()
 44 ssh.connect()
 45 ssh.cmd("ls")
 46 ssh.upload('s1.py','/tmp/ks77.py')
 47 ssh.download('/tmp/test.py','kkkk',)
 48 ssh.cmd("df")
 49 ssh.close()
