python paramiko模块

Posted 2020-09-07

paramiko模块，该模块机遇SSH用于连接远程服务器并执行相关操作

SSHClient

基于用户名密码连接：

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=‘127.0.0.1‘, port=22, username=‘ubuntu‘, password=‘123‘)
  
# 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()

基于公钥密钥连接：

import paramiko
 
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=‘127.0.0.1‘, port=22, username=‘ubuntu‘, 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()

SFTPClient

用于连接远程服务器并执行上传下载

基于用户名密码上传下载

import paramiko
 
transport = paramiko.Transport((‘hostname‘,22))
transport.connect(username=‘ubuntu‘,password=‘123‘)
 
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()

基于公钥密钥上传下载

import paramiko
 
private_key = paramiko.RSAKey.from_private_key_file(‘/home/auto/.ssh/id_rsa‘)
 
transport = paramiko.Transport((‘hostname‘, 22))
transport.connect(username=‘ubuntu‘, 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()
