[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()
