python之旅十【第十篇】paramiko模块

paramiko模块介绍

ssh的远程连接

基于用户名密码的连接

 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='x.x.x.x', port=, username='xiaoli, password='')

 # 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()

基于封装的transport的连接

 import paramiko

 # 创建transport对象

 transport = paramiko.Transport(('x.x.x.x', ))

 transport.connect(username='xiaoli', password='')

 ssh = paramiko.SSHClient()

 ssh._transport = transport

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

 print stdout.read()

 transport.close()

基于公钥密钥连接

 跟密码连接差不多，只是密码的地方变成了私钥

 import paramiko

 #私钥路径

 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='x.x.x.x, port=22, username='xiaoli, key=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()

基于封装的transport的连接

 同理，跟上边的差不多

 import paramiko

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

 transport = paramiko.Transport(('x.x.x.x', ))

 transport.connect(username='xiaoli', pkey=private_key)

 ssh = paramiko.SSHClient()

 ssh._transport = transport

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

 transport.close()

SFTP的上传下载

基于用户名密码的上传下载，只支持transport形式的连接然后实现上传下载

 简单小例

 import paramiko

 transport = paramiko.Transport(('x.x.x.x',))

 transport.connect(username='xiaoli',password='')

 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()

基于密钥的上传下载

 import paramiko

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

 transport = paramiko.Transport(('x.x.x.x.', ))

 transport.connect(username='xiaoli', pkey=private_key )

 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()

一个简单的上传下载，文件

 #!/usr/bin/env python

 #_*_coding:utf-8_*_

 #上传以及重命名

 import paramiko

 import uuid

 class Haproxy(object):

     def __init__(self):

         self.host = 'x.x.x.x.'

         self.port =

         self.username = 'root'

         self.pwd = ''

     def create_file(self):

         filename = str(uuid.uuid4())

         with open(filename,'w') as f:

             f.write('sb')

         return filename

     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 run(self):

         self.connect()

         self.upload()

         self.rename()

         self.close()

     def upload(self):

         file_name = self.create_file()

         sftp = paramiko.SFTPClient.from_transport(self.__transport)

         sftp.put(file_name,'/home/zdk/tttttt.py')

     def rename(self):

         ssh = paramiko.SSHClient()

         ssh._transport = self.__transport

         stdin, stdout ,stderr = ssh.exec_command('mv /home/zdk/tttttt.py /home/zdk/aaaaaaa.py')

         result =  stdout.read()

         ssh.close()

 a = Haproxy()

 a.run()
