#!/usr/bin/python

from socket import socket, AF_INET, SOCK_STREAM
from threading import Thread

port = 50008
host = 'localhost'

def server():
sock = socket(AF_INET, SOCK_STREAM)
sock.bind(('', port))
sock.listen(5)
while True:
conn, addr = sock.accept()
data = conn.recv(1024)
reply = 'server got: [%s]' % data
conn.send(reply.encode())

def client(name):
sock = socket(AF_INET, SOCK_STREAM)
sock.connect((host, port))
sock.send(name.encode())
reply = sock.recv(1024)
sock.close()
print('client got: [%s]' % reply)

if __name__ == '__main__':

sthread = Thread(target=server)
sthread.daemon = True
sthread.start()
for i in range(5):
Thread(target=client, args=('client%s' % i,)).start()

在ubuntu下运行，报下面的异常信息：
Exception in thread Thread-2:
Traceback (most recent call last):
File "/usr/lib/python3.2/threading.py", line 740, in _bootstrap_inner
self.run()
File "/usr/lib/python3.2/threading.py", line 693, in run
self._target(*self._args, **self._kwargs)
File "./socket_test.py", line 21, in client
sock.connect((host, port))
socket.error: [Errno 111] Connection refused

把socket绑定的端口改为5000后，就没有异常。

client got: [server got: [client1]]
client got: [server got: [client0]]
client got: [server got: [client2]]
client got: [server got: [client3]]
client got: [server got: [client4]]

我这正常的，你那是不是有两个服务器同时开了？把原来那个杀掉。
