Question

fork()创建网络并发连接，运行时出现ConnectionRefusedError: [Errno 111] Connection refused

#服务端
from socket import *
import os
import signal

HOST = '127,0,0,1'
PORT = 8888
ADDR = (HOST,PORT)

def handle(c):
    while True:
        data = c.recv(1024)
        if not data:
            break
        print(data.decode())
        c.send(b'OK')
        c.close()

s = socket()
s.setsockopt(SOL_SOCKET,SO_REUSEADDR,1)
s.listen(5)

signal.signal(signal.SIGCHLD,signal.SIG_IGN)

print('Listen the port 8888.....')

while True:
    try:
        c,addr = s.accept()
        print('Connect from',addr)  
    except KeyboardInterrupt as e:
        os._exit(0)
    except Exception as e:
        print(e)
        continue   

    pid = os.fork()

    if pid == 0:
        s.close()
        handle(c)
        os._exit(0)
    else:
        c.close()

#客户端
sockfd = socket()  

server_addr = ('127.0.0.1',8888)   
sockfd.connect(server_addr)

while True: 
    msg = input('Msg:')
    if not msg:    
        break
    sockfd.send(msg.encode()) 
    data = sockfd.recv(5)
    print('From server:',data.decode())    

sockfd.close()
