Question

我在linux上收到此错误，但是在Windows中就可以了。

这是用于运行nginx，uwsgi和Python3.7的新Linux服务器（cento7）。我在Python中导入“套接字”和“线程”。过去，我曾尝试在现有服务器上删除“线程”，但与OSError相同：[Errno 22]无效的参数。

import threading
from socket import *

try:
    HOST = 'localhost'
    PORT = 3333  # The default port for modbus-TCP
    ADDR = (HOST, PORT)
    server = socket(AF_INET, SOCK_STREAM)
    server.setsockopt(SOL_SOCKET, SO_REUSEADDR, 1)
    server.bind(ADDR)   
    server.listen(5)    
    print(PORT, 'Port open.')
except OSError:
    print('Port open fail.')


def recs():
    while True:
        clientsock, clientaddress = server.accept()
        if clientaddress[0] not in conn_list:
            conn_list.append(clientaddress[0])
            conn_dt[clientaddress[0]] = clientsock
            ip_ModbusDict[clientaddress[0]] = {}
        else:
            conn_dt[clientaddress[0]] = clientsock
        print(datetime.datetime.now(), clientaddress[0], "connection.")
        t = threading.Thread(target=tcplink, args=(clientsock, clientaddress))
        t.start()


t1 = threading.Thread(target=recs, args=(), name='recs')
t1.start()

3333 Port open.
Port open fail.
Traceback (most recent call last):

    fd, addr = self._accept()
OSError: [Errno 22] Invalid argument

如何解决centos7中的“ OSError：[Errno 22]无效参数”错误
