Python套接字编程中的Errno 111连接被拒绝

我有两个python脚本：一个server.py和一个worker.py这应该是这样工作的：

- server.py listens on 5005
- workers are started and bind to random ports
- they send a message to the server with their port nr
- server adds the port to its list of known workers
- it does this for each worker

我遇到的问题是，在添加第一个工作程序并启动另一个工作程序之后，我在服务器端收到此错误：

Traceback (most recent call last):
  File "/usr/lib/python2.7/multiprocessing/process.py", line 258, in _bootstrap
    self.run()
  File "/usr/lib/python2.7/multiprocessing/process.py", line 114, in run
    self._target(*self._args, **self._kwargs)
  File "server.py", line 42, in listener
    if handle_join(data.split(',')[1:]) == 1:
  File "server.py", line 122, in handle_join
    s.connect(("",int(worker_ip_port[1])))
  File "/usr/lib/python2.7/socket.py", line 224, in meth
    return getattr(self._sock,name)(*args)
error: [Errno 111] Connection refused

该应用程序已经增长了很多，所以我只在此处包括相关部分：server.py：

def handle_join(worker_ip_port):
# e.g. worker_ip_port = 127.0.0.1,55256
# 
#
    worker_ip_port = tuple(worker_ip_port)
        s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
        s.setsockopt(socket.SOL_SOCKET, socket.SO_REUSEADDR, 1)
        print "Trying to connect to {}".format(worker_ip_port)
        s.connect(("",int(worker_ip_port[1])))
    if worker_ip_port not in WORKERS:
        WORKERS.append(worker_ip_port)
        print '\t\tNew worker added on {}'.format(worker_ip_port)
        print '\t\tWORKERS: {}'.format(WORKERS)
                s.send('0'+SIGEND)
                s.close()
                return 0
    print '\t\tThat port is already in the worker list'
    s.send('1'+SIGEND)
    s.close()
    return 1

worker.py

def read_socket():
# binds socket, keeps listening
# once connection is accepted, loops over the socket buffer until the
# signal for transmission end
# then returns the data
   s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
   s.setsockopt(socket.SOL_SOCKET, socket.SO_REUSEADDR, 1)
   s.bind(("",WORKER_PORT))
   print "listening on {}".format(WORKER_PORT)
   while True:
           buffer = ''
           data = True
           s.listen(0)
           conn, addr = s.accept()
           print "accepted connection"
           while data:
                    data = conn.recv(BUFFER_SIZE)
                    # if the SIGNAL for end of packet is found in current packet
                    # add only up to that part
                    # close socket
                    # return data
                    if data.find(SIGEND) != -1:
                            buffer += data[:data.rfind(SIGEND)]
                            conn.close()
                            s.close()
                            return buffer
                    else:
                            buffer += data

注意：我已经尝试过Linux和Windows。我已阅读了该网站上的所有其他建议以及在Google上可以找到的所有内容。似乎都不起作用。

尝试将telnet连接到第二个工作者建立的连接：

Trying ::1...
Trying 127.0.0.1...
Connected to localhost.
Escape character is '^]'.

据我所知，SECOND worker没有从服务器获得任何连接。

netstat的输出也很有趣：

tcp        0      0 0.0.0.0:55271           0.0.0.0:*               LISTEN
tcp        0      0 127.0.0.1:5005          127.0.0.1:55271         TIME_WAIT

55271是SECOND工作者绑定到的端口；以下连接是用于将“我在这里”消息发送到服务器的连接；

tcp        0      0 0.0.0.0:55269           0.0.0.0:*               LISTEN
tcp        0      0 127.0.0.1:59240         127.0.0.1:55269         TIME_WAIT
tcp        0      0 127.0.0.1:5005          127.0.0.1:55269         TIME_WAIT

对于FIRST工人（此处为55269），我可以看到有两个连接。应该的。第一个从工作器到服务器，带有“ I AM HERE”。第二个是从服务器发给工作人员的，确认一切都很好，现在已经在工作人员列表中。

我正在使用多处理框架。那会是个问题吗？
