使用
（1）SSHClient
用於連接遠程服務器並執行基本命令
基於用戶名密碼連接：
#!/usr/bin/env python
# Version = 3.5.2
# __auth__ = '無名小妖'
import paramiko
# 創建SSH對象
ssh = paramiko.SSHClient()
# 允許連接不在know_hosts文件中的主機
ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy())
# 連接服務器
ssh.connect(hostname='192.168.168.231', port=22, username='oracle', password='oracle')
# 執行命令
stdin, stdout, stderr = ssh.exec_command('ls')
# 獲取命令結果
result = stdout.read()
print(result.decode())
# 關閉連接
ssh.close()
-----------------
使用transport ：
#!/usr/bin/env python
# Version = 3.5.2
# __auth__ = '無名小妖'
import paramiko
transport = paramiko.Transport(('192.168.168.231', 22))
transport.connect(username='oracle', password='oracle')
ssh = paramiko.SSHClient()
ssh._transport = transport
stdin, stdout, stderr = ssh.exec_command('df')
print(stdout.read().decode())
transport.close()
--------------------------
（2）SFTPClient
用於連接遠程服務器並執行上傳下載
基於用戶名密碼上傳下載：
import
paramiko
transport
=
paramiko.Transport((
'
192.168.168.231
'
,
22
))
transport.connect(username
=
'root'
,password
=
'123456'
)
sftp
=
paramiko.SFTPClient.from_transport(transport)
# 將location.py 上傳至服務器 /tmp/test.py
sftp.put(
'/tmp/location.py'
,
'/tmp/test.py'
)
# 將remove_path 下載到本地 local_path
sftp.get(
'remove_path'
,
'local_path'
)
transport.close()
---------------------------------------------------------------------
基於公鑰密鑰連接：
import
paramiko
private_key
=
paramiko.RSAKey.from_private_key_file(
'/home/auto/.ssh/id_rsa'
)
# 創建SSH對象
ssh
=
paramiko.SSHClient()
# 允許連接不在know_hosts文件中的主機
ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy())
# 連接服務器
ssh.connect(hostname
=
'c1.salt.com'
, port
=
22
, username
=
'wupeiqi'
, key
=
private_key)
# 執行命令
stdin, stdout, stderr
=
ssh.exec_command(
'df'
)
# 獲取命令結果
result
=
stdout.read()
# 關閉連接
ssh.close()
-------------------------------------------------------------------------
基於公鑰密鑰上傳下載：
import
paramiko
private_key
=
paramiko.RSAKey.from_private_key_file(
'/home/auto/.ssh/id_rsa'
)
transport
=
paramiko.Transport((
'hostname'
,
22
))
transport.connect(username
=
'wupeiqi'
, pkey
=
private_key )
sftp
=
paramiko.SFTPClient.from_transport(transport)
# 將location.py 上傳至服務器 /tmp/test.py
sftp.put(
'/tmp/location.py'
,
'/tmp/test.py'
)
# 將remove_path 下載到本地 local_path
sftp.get(
'remove_path'
,
'local_path'
)
transport.close()
-------------------------------------------------------------------------------------
實用小例子：(使用transport既執行命令又上傳下載文件)
#!/usr/bin/env python
# Version = 3.5.2
# __auth__ = '無名小妖'
import paramiko
class SSHConnection(object):
def __init__(self, host='192.168.168.231', port=22, username='oracle', pwd='oracle'):
self.host = host
self.port = port
self.username = username
self.pwd = pwd
self.__k = None
def run(self):
self.connect()
pass
self.close()
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 cmd(self, command):
ssh = paramiko.SSHClient()
ssh._transport = self.__transport
# 執行命令
stdin, stdout, stderr = ssh.exec_command(command)
# 獲取命令結果
result = stdout.read()
return result
def upload(self,local_path, target_path):
# 連接，上傳
sftp = paramiko.SFTPClient.from_transport(self.__transport)
# 將location.py 上傳至服務器 /tmp/test.py
sftp.put(local_path, target_path)
ssh = SSHConnection()
ssh.connect()
r1 = ssh.cmd('df')
print(r1.decode())
ssh.upload('class12.py', "test.py")
ssh.close()
-------------------------------------------------------------------
實現遠程登錄並進行操作
#!/usr/bin/env python # Version = 3.5.2 # __auth__ = '無名小妖' import paramiko import sys import os import socket import select import getpass from paramiko.py3compat import u tran = paramiko.Transport(('192.168.191.3', 22,)) tran.start_client() tran.auth_password('root', '7ujm8ik,') # 打開一個通道 chan = tran.open_session() # 獲取一個終端 chan.get_pty() # 激活器 chan.invoke_shell() while True: # 監視用戶輸入和服務器返回數據 # sys.stdin 處理用戶輸入 # chan 是之前創建的通道，用於接收服務器返回信息 readable, writeable, error = select.select([chan, sys.stdin, ], [], [], 1) if chan in readable: try: x = u(chan.recv(1024)) if len(x) == 0: print('\r\n*** EOF\r\n') break sys.stdout.write(x) sys.stdout.flush() except socket.timeout: pass if sys.stdin in readable: inp = sys.stdin.readline() chan.sendall(inp) chan.close() tran.close()
