Python学习记录-paramiko模块

[TOC]

paramiko模块基于SSH用于连接远程服务器并执行相关操作。

1. SSHClient

用于连接远程服务器并执行基本命令

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='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 封装 Transport

import paramiko    transport = paramiko.Transport(('192.168.0.2', 22))  transport.connect(username='root', password='test')    ssh = paramiko.SSHClient()  ssh._transport = transport    stdin, stdout, stderr = ssh.exec_command('df')  print(stdout.read().decode())    transport.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='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 封装 Transport

import paramiko    private_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 = transport    stdin, stdout, stderr = ssh.exec_command('df')    transport.close()

基于私钥字符串进行连接

import paramiko  from io import StringIO    key_str = """-----BEGIN RSA PRIVATE KEY-----  MIIEpQIBAAKCAQEAq7gLsqYArAFco02/55IgNg0r7NXOtEM3qXpb/dabJ5Uyky/8  NEHhFiQ7deHIRIuTW5Zb0kD6h6EBbVlUMBmwJrC2oSzySLU1w+ZNfH0PE6W6fans  H80whhuc/YgP+fjiO+VR/gFcqib8Rll5UfYzf5H8uuOnDeIXGCVgyHQSmt8if1+e  7hn1MVO1Lrm9Fco8ABI7dyv8/ZEwoSfh2C9rGYgA58LT1FkBRkOePbHD43xNfAYC  tfLvz6LErMnwdOW4sNMEWWAWv1fsTB35PAm5CazfKzmam9n5IQXhmUNcNvmaZtvP  c4f4g59mdsaWNtNaY96UjOfx83Om86gmdkKcnwIDAQABAoIBAQCnDBGFJuv8aA7A  ZkBLe+GN815JtOyye7lIS1n2I7En3oImoUWNaJEYwwJ8+LmjxMwDCtAkR0XwbvY+  c+nsKPEtkjb3sAu6I148RmwWsGncSRqUaJrljOypaW9dS+GO4Ujjz3/lw1lrxSUh  IqVc0E7kyRW8kP3QCaNBwArYteHreZFFp6XmtKMtXaEA3saJYILxaaXlYkoRi4k8  S2/K8aw3ZMR4tDCOfB4o47JaeiA/e185RK3A+mLn9xTDhTdZqTQpv17/YRPcgmwz  zu30fhVXQT/SuI0sO+bzCO4YGoEwoBX718AWhdLJFoFq1B7k2ZEzXTAtjEXQEWm6  01ndU/jhAasdfasdasdfasdfa3eraszxqwefasdfadasdffsFIfAsjQb4HdkmHuC  OeJrJOd+CYvdEeqJJNnF6AbHyYHIECkj0Qq1kEfLOEsqzd5nDbtkKBte6M1trbjl  HtJ2Yb8w6o/q/6Sbj7wf/cW3LIYEdeVCjScozVcQ9R83ea05J+QOAr4nAoGBAMaq  UzLJfLNWZ5Qosmir2oHStFlZpxspax/ln7DlWLW4wPB4YJalSVovF2Buo8hr8X65  lnPiE41M+G0Z7icEXiFyDBFDCtzx0x/RmaBokLathrFtI81UCx4gQPLaSVNMlvQA  539GsubSrO4LpHRNGg/weZ6EqQOXvHvkUkm2bDDJAoGATytFNxen6GtC0ZT3SRQM  WYfasdf3xbtuykmnluiofasd2sfmjnljkt7khghmghdasSDFGQfgaFoKfaawoYeH  C2XasVUsVviBn8kPSLSVBPX4JUfQmA6h8HsajeVahxN1U9e0nYJ0sYDQFUMTS2t8  RT57+WK/0ONwTWHdu+KnaJECgYEAid/ta8LQC3p82iNAZkpWlGDSD2yb/8rH8NQg  9tjEryFwrbMtfX9qn+8srx06B796U3OjifstjJQNmVI0qNlsJpQK8fPwVxRxbJS/  pMbNICrf3sUa4sZgDOFfkeuSlgACh4cVIozDXlR59Z8Y3CoiW0uObEgvMDIfenAj  98pl3ZkCgYEAj/UCSni0dwX4pnKNPm6LUgiS7QvIgM3H9piyt8aipQuzBi5LUKWw  DlQC4Zb73nHgdREtQYYXTu7p27Bl0Gizz1sW2eSgxFU8eTh+ucfVwOXKAXKU5SeI  +MbuBfUYQ4if2N/BXn47+/ecf3A4KgB37Le5SbLDddwCNxGlBzbpBa0=  -----END RSA PRIVATE KEY-----"""    private_key = paramiko.RSAKey(file_obj=StringIO(key_str))  transport = paramiko.Transport(('10.0.1.40', 22))  transport.connect(username='root', pkey=private_key)    ssh = paramiko.SSHClient()  ssh._transport = transport    stdin, stdout, stderr = ssh.exec_command('df')  result = stdout.read()    transport.close()    print(result)

2. 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='root',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='root', 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()
