[TOC]

The Paramiko module is based on SSH for connecting to a remote server and performing related operations.

1. SSHClient

Used to connect to a remote server and execute basic commands

Connect based on user name password:

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=‘192.168.0.2‘, port=22, username=‘root‘, password=‘test‘)# 执行命令stdin, stdout, stderr = ssh.exec_command(‘df‘)# 获取命令结果result = stdout.read().decode()# 关闭连接ssh.close()

Sshclient Package Transport

import paramikotransport = paramiko.Transport((‘192.168.0.2‘, 22))transport.connect(username=‘root‘, password=‘test‘)ssh = paramiko.SSHClient()ssh._transport = transportstdin, stdout, stderr = ssh.exec_command(‘df‘)print(stdout.read().decode())transport.close()

Connection based on public key:

import paramikoprivate_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=‘192.168.0.2‘, port=22, username=‘root‘, 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()

Sshclient Package Transport

import paramikoprivate_key = paramiko.RSAKey.from_private_key_file(‘/home/auto/.ssh/id_rsa‘)transport = paramiko.Transport((‘hostname‘, 22))transport.connect(username=‘root‘, pkey=private_key)ssh = paramiko.SSHClient()ssh._transport = transportstdin, stdout, stderr = ssh.exec_command(‘df‘)transport.close()

Connect based on a private key string

2. SFTPClient

For connecting to a remote server and performing an upload download

Upload and download based on user name password

import paramikotransport = paramiko.Transport((‘hostname‘,22))transport.connect(username=‘root‘,password=‘123‘)sftp = paramiko.SFTPClient.from_transport(transport)# 将location.py 上传至服务器 /tmp/test.pysftp.put(‘/tmp/location.py‘, ‘/tmp/test.py‘)# 将remove_path 下载到本地 local_pathsftp.get(‘remove_path‘, ‘local_path‘)transport.close()

Upload and download based on public key keys

import paramikoprivate_key = paramiko.RSAKey.from_private_key_file(‘/home/auto/.ssh/id_rsa‘)transport = paramiko.Transport((‘hostname‘, 22))transport.connect(username=‘root‘, pkey=private_key )sftp = paramiko.SFTPClient.from_transport(transport)# 将location.py 上传至服务器 /tmp/test.pysftp.put(‘/tmp/location.py‘, ‘/tmp/test.py‘)# 将remove_path 下载到本地 local_pathsftp.get(‘remove_path‘, ‘local_path‘)transport.close()
