Python实现跨机器隧道打通的示例代码

client = paramiko.SSHClient()
# client.load_system_host_keys()
# 允许连接不在know_hosts文件中的主机
client.set_missing_host_key_policy(paramiko.AutoAddPolicy())
client.connect(hostname='jump_server_ip', port=22, username='root', password='pwd')
# 私钥方式
# pkey = paramiko.RSAKey.from_private_key_file(id_rsa_path)  # 私钥
# client.connect(hostname=hostname, port=port, username=username, pkey=pkey)  
stdin, stdout, stderr = client.exec_command('pwd')  # 执行命令
code, out, err = stdout.channel.recv_exit_status(), stdout.read(), stderr.read()
client.close()

with sshtunnel.open_tunnel(
    ssh_address_or_host='jump_server_ip',
    ssh_username='root',
    ssh_password='pwd',
    # ssh_pkey='local_id_rda',
    remote_bind_address=('private_server_ip', 22),
    # local_bind_address=('127.0.0.1', 10022)  # 绑定本机10022端口
) as tunnel:
    client = paramiko.SSHClient()
    client.set_missing_host_key_policy(paramiko.AutoAddPolicy())
    client.connect(hostname='127.0.0.1', port=tunnel.local_bind_port, username='root', password='pwd')
    # pkey = paramiko.RSAKey.from_private_key_file('jump_id_rda')  # 跳板机的私钥
