python address already in use

在socket中使用

phone=socket(AF_INET,SOCK_STREAM)
phone.setsockopt(SOL_SOCKET,SO_REUSEADDR,1) #就是它，在bind前加
phone.bind(('127.0.0.1',8080))

在socketserver中使用

# allow_reuse_address should be on the class, not on the instance.
socketserver.TCPServer.allow_reuse_address = True
server = socketserver.TCPServer((HOST, PORT), MyTCPHandler)
