[python] 解决OSError: Address already in use

Posted 2020-11-20

用python http.sever实现web服务时，绑定端口由于强制退出导致再次启动服务报错：
self.socket.bind(self.server_address)
OSError: [Errno 48] Address already in use

临时解决办法：
查找端口被占用的进程，然后强制结束
lsof -i:9090
然后kill对应的进程

from http.server import BaseHTTPRequestHandler, HTTPServer
import time
import socket

class CarServer(BaseHTTPRequestHandler):
def get_host_ip(self):

def do_GET(self):
    self.send_response(200)
    self.send_header("Content-type", "text/html")
    self.end_headers()
    self.wfile.write("Hello World !".encode())

if name == "main":
socket.set
myServer = HTTPServer(("192.168.1.101", 9090), CarServer)
print(time.asctime(), "Server Starts - %s:%s" % ("a","b"))

try:
    myServer.serve_forever()
except KeyboardInterrupt:
    pass
