linux 创建监听服务

import socket

# 创建一个TCP/IP套接字
server_socket = socket.socket(socket.AF_INET, socket.SOCK_STREAM)

# 绑定套接字到地址和端口
server_address = ('localhost', 10000)
print('starting up on {} port {}'.format(*server_address), file=sys.stderr)
server_socket.bind(server_address)

# 监听传入连接
server_socket.listen(1)

while True:
    # 等待连接
    print('waiting for a connection', file=sys.stderr)
    connection, client_address = server_socket.accept()
    
    try:
        print('connection from', client_address, file=sys.stderr)
        
        # 接收数据
        while True:
            data = connection.recv(16)
            print('received {!r}'.format(data), file=sys.stderr)
            if data:
                print('sending data back to the client', file=sys.stderr)
                connection.sendall(data)
            else:
                # 没有数据，断开连接
                break
    finally:
        # 清理连接
        connection.close()
