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

 1 import paramiko
 2   
 3 # 创建SSH对象
 4 ssh = paramiko.SSHClient()
 5 # 允许连接不在know_hosts文件中的主机
 6 ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy())
 7 # 连接服务器
 8 ssh.connect(hostname='x.x.x.x', port=22, username='xiaoli, password='123456')
 9   
10 # 执行命令
11 stdin, stdout, stderr = ssh.exec_command('df')
12 # 获取命令结果
13 result = stdout.read()
14   
15 # 关闭连接
16 ssh.close()

基于封装的transport的连接

 1 import paramiko
 2 
 3 #1 创建transport对象
 4 transport = paramiko.Transport(('x.x.x.x', 22))
 5 transport.connect(username='xiaoli', password='123456')
 6 
 7 ssh = paramiko.SSHClient()
 8 ssh._transport = transport
 9 
10 stdin, stdout, stderr = ssh.exec_command('df')
11 print stdout.read()
12 
13 transport.close()

基于公钥密钥连接

 1 跟密码连接差不多，只是密码的地方变成了私钥
 2 
 3 import paramiko
 4  
 5 #私钥路径
 6 private_key = paramiko.RSAKey.from_private_key_file('/home/auto/.ssh/id_rsa')
 7  
 8 # 创建SSH对象
 9 ssh = paramiko.SSHClient()
10 # 允许连接不在know_hosts文件中的主机
11 ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy())
12 # 连接服务器
13 ssh.connect(hostname='x.x.x.x, port=22, username='xiaoli, key=private_key)
14  
15 # 执行命令
16 stdin, stdout, stderr = ssh.exec_command('df')
17 # 获取命令结果
18 result = stdout.read()
19  
20 # 关闭连接
21 ssh.close()

基于封装的transport的连接

 1 同理，跟上边的差不多
 2 
 3 import paramiko
 4 
 5 private_key = paramiko.RSAKey.from_private_key_file('/home/auto/.ssh/id_rsa')
 6 
 7 transport = paramiko.Transport(('x.x.x.x', 22))
 8 transport.connect(username='xiaoli', pkey=private_key)
 9 
10 ssh = paramiko.SSHClient()
11 ssh._transport = transport
12 
13 stdin, stdout, stderr = ssh.exec_command('df')
14 
15 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

 1 简单小例
 2 
 3 import paramiko
 4  
 5 transport = paramiko.Transport(('x.x.x.x',22))
 6 transport.connect(username='xiaoli',password='123456')
 7  
 8 sftp = paramiko.SFTPClient.from_transport(transport)
 9 # 将location.py 上传至服务器 /tmp/test.py
10 sftp.put('/tmp/location.py', '/tmp/test.py')
11 # 将remove_path 下载到本地 local_path
12 sftp.get('remove_path', 'local_path')
13  
14 transport.close()
View Code

基于密钥的上传下载

 1 import paramiko
 2  
 3 private_key = paramiko.RSAKey.from_private_key_file('/home/auto/.ssh/id_rsa')
 4  
 5 transport = paramiko.Transport(('x.x.x.x.', 22))
 6 transport.connect(username='xiaoli', pkey=private_key )
 7  
 8 sftp = paramiko.SFTPClient.from_transport(transport)
 9 # 将location.py 上传至服务器 /tmp/test.py
10 sftp.put('/tmp/location.py', '/tmp/test.py')
11 # 将remove_path 下载到本地 local_path
12 sftp.get('remove_path', 'local_path')
13  
14 transport.close()

一个简单的上传下载，文件

 1 #!/usr/bin/env python
 2 #_*_coding:utf-8_*_
 3 
 4 #上传以及重命名
 5 import paramiko
 6 import uuid
 7 class Haproxy(object):
 8     def __init__(self):
 9         self.host = 'x.x.x.x.'
10         self.port = 22
11         self.username = 'root'
12         self.pwd = '123456'
13     def create_file(self):
14         filename = str(uuid.uuid4())
15         with open(filename,'w') as f:
16             f.write('sb')
17         return filename
18     def connect(self):
19         transport = paramiko.Transport((self.host,self.port))
20         transport.connect(username=self.username,password=self.pwd)
21         self.__transport = transport
22     def close(self):
23         self.__transport.close()
24     def run(self):
25         self.connect()
26         self.upload()
27         self.rename()
28         self.close()
29 
30     def upload(self):
31         file_name = self.create_file()
32         sftp = paramiko.SFTPClient.from_transport(self.__transport)
33         sftp.put(file_name,'/home/zdk/tttttt.py')
34 
35 
36     def rename(self):
37         ssh = paramiko.SSHClient()
38         ssh._transport = self.__transport
39         stdin, stdout ,stderr = ssh.exec_command('mv /home/zdk/tttttt.py /home/zdk/aaaaaaa.py')
40         result =  stdout.read()
41         ssh.close()
42 a = Haproxy()
43 a.run()
