  • python paramiko模块(ssh) 使用

    1. 安装

    pip3 install paramiko

    2. 示例一

    基于密码的连接

    复制代码
    import paramiko
    
    ssh = paramiko.SSHClient()
    
    ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy())
    
    ssh.connect(hostname='192.168.31.100',port=22,username='root',password='123456')
    
    stdin, stdout ,stderr = ssh.exec_command('df')
    
    result = stdout.read()
    
    ssh.close()
    
    print(str(result,encoding='utf-8'))
    复制代码

    3. 示例二

    基于秘钥的连接

    复制代码
    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='192.168.31.100', 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()
    复制代码

    4. 基于字符串形式的私钥连接

    复制代码
    import paramiko
    from io import StringIO
    
    # 一般可以从数据库里读取秘钥字符串
    key_str = """-----BEGIN RSA PRIVATE KEY-----

    # 使用StringIO对象的形式读取秘钥
    private_key = paramiko.RSAKey(file_obj=StringIO(key_str))
    transport = paramiko.Transport(('10.0.1.40', 22))
    transport.connect(username='wupeiqi', pkey=private_key)
    
    ssh = paramiko.SSHClient()
    ssh._transport = transport
    
    stdin, stdout, stderr = ssh.exec_command('df')
    result = stdout.read()
    
    transport.close()
    
    print(result)
    
    复制代码

    5. 上传下载基于密码

    复制代码
    import paramiko
     
    transport = paramiko.Transport(('hostname',22))
    transport.connect(username='wupeiqi',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()
    复制代码

    6.上传下载基于秘钥

    复制代码
    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)
    # 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()
