Python - socket.error: Cannot assign requested address
提问by llllllllll
I have written a chat server but I cannot bind my socket to an IP address:
我编写了一个聊天服务器，但我无法将套接字绑定到 IP 地址：
import sys
import os
import socket
HOST = "194.118.168.131"
SOCKET_LIST = []
RECV_BUFFER = 4096
PORT = 9009
def chat_server():
server_socket = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
server_socket.setsockopt(socket.SOL_SOCKET, socket.SO_REUSEADDR, 1)
server_socket.bind((HOST, PORT))
server_socket.listen(10)
...
I get the following error:
我收到以下错误：
Traceback (most recent call last):
File "server.py", line 83, in <module>
sys.exit(chat_server())
File "server.py", line 20, in chat_server
server_socket.bind((HOST, PORT))
File "/usr/lib/python2.7/socket.py", line 224, in meth
return getattr(self._sock,name)(*args)
socket.error: [Errno 99] Cannot assign requested address
What's wrong with my code?
我的代码有什么问题？
I didn't find an answer on:
我没有找到答案：
'Connection aborted.', error(99, 'Cannot assign requested address') error in Python,
socket.error[Errno 99] Cannot assign requested address,
bind: cannot assign requested address
Cannot assign requested address - possible causes?
'连接中止。'，错误（99，'无法分配请求的地址'）Python中的错误，
socket.error [Errno 99]无法分配请求的地址，
绑定：无法分配请求的地址
无法分配请求的地址 - 可能的原因？

By checking errno.h, errno 99 is EADDRNOTAVAIL. The man page bind(2)says:
通过检查errno.h， errno 99 是EADDRNOTAVAIL。手册页bind(2)说：
EADDRNOTAVAIL A nonexistent interface was requested or the requested address was not local.
EADDRNOTAVAIL 请求了一个不存在的接口或请求的地址不是本地的。
It is often caused by a wrong IP address. You can use the command ifconfigto check whether your machine has this IP address.
它通常是由错误的 IP 地址引起的。您可以使用ifconfig命令 来检查您的机器是否有这个 IP 地址。
