paramiko远程模块

1.基于密码的ssh

 1 import paramiko
 2 
 3 #创建SSH对象
 4 ssh = paramiko.SSHClient()
 5 
 6 #把要连接的机器添加到known_hosts文件中
 7 ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy())
 8 
 9 #连接服务器
10 ssh.connect(hostname='192.168.1.96', port=22, username='morra', password='123456')
11 
12 cmd = 'ps'
13 #cmd = 'ls -l;ifconfig'       #多个命令用;隔开
14 stdin, stdout, stderr = ssh.exec_command(cmd)
15 
16 result = stdout.read()
17 
18 if not result:
19     result = stderr.read()
20 ssh.close()
21 
22 print(result.decode())

2.基于密码的Sftp传输

 1 import paramiko
 2 
 3 transport = paramiko.Transport(('192.168.1.96', 22))
 4 
 5 transport.connect(username='morra', password='357447218')
 6 
 7 sftp = paramiko.SFTPClient.from_transport(transport)
 8 
 9 sftp.put('123.py', '/tmp/test.py')  # 将123.py 上传至服务器 /tmp下并改名为test.py
10 
11 sftp.get('remove_path', 'local_path')  # 将remove_path 下载到本地 local_path

3.使用密钥对ssh

 1 import paramiko
 2 
 3 private_key = paramiko.RSAKey.from_private_key_file('id_rsa96')   #使用目标的私钥来登录
 4 
 5 ssh = paramiko.SSHClient()
 6 ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy())
 7 
 8 ssh.connect(hostname='192.168.1.96',port=22,username='morra',pkey=private_key)
 9 
10 cmd = 'ps'
11 stdin, stdout, stderr = ssh.exec_command(cmd)
12 
13 result = stdout.read()
14 
15 if not result:
16     result = stderr.read()
17 ssh.close()
18 
19 print(result.decode())

4.使用密钥对Sftp

 1 import paramiko
 2 
 3 private_key = paramiko.RSAKey.from_private_key_file('id_rsa96')   #使用目标的私钥来登录
 4 
 5 ssh = paramiko.SSHClient()
 6 ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy())
 7 
 8 ssh.connect(hostname='192.168.1.96',port=22,username='morra',pkey=private_key)
 9 
10 cmd = 'ps'
11 stdin, stdout, stderr = ssh.exec_command(cmd)
12 
13 result = stdout.read()
14 
15 if not result:
16     result = stderr.read()
17 ssh.close()
18 
19 print(result.decode())

5小总结

 1 import paramiko
 2 import uuid
 3 
 4 class Haproxy(object):
 5 
 6     def __init__(self):
 7         self.host = '192.168.1.96'
 8         self.port = 22
 9         self.username = 'morra'
10         self.pwd = '123456'
11         self.__k = None
12 
13     def create_file(self):
14         file_name = str(uuid.uuid4())
15         with open(file_name,'w') as f:
16             f.write('sb')
17         return file_name
18 
19     def run(self):
20         self.connect()
21         self.upload()
22         self.rename()
23         self.close()
24 
25     def connect(self):
26         transport = paramiko.Transport((self.host,self.port))
27         transport.connect(username=self.username,password=self.pwd)
28         self.__transport = transport
29 
30     def close(self):
31 
32         self.__transport.close()
33 
34     def upload(self):
35         # 连接，上传
36         file_name = self.create_file()
37 
38         sftp = paramiko.SFTPClient.from_transport(self.__transport)
39         sftp.put(file_name, '/home/test.py')    # 将location.py 上传至服务器 /tmp/test.pydef rename(self):
40 
41         ssh = paramiko.SSHClient()
42         ssh._transport = self.__transport # 执行命令
43         stdin, stdout, stderr = ssh.exec_command('mv /home/test.py /home/test2.py') 
44         result = stdout.read()
45 
46 
47 ha = Haproxy()
48 ha.run()
