仅供参考，可以绑定到0.0.0.0，就可以从外网访问了，IP就是主机地址

def main():
    parse_options()
    http_server = tornado.httpserver.HTTPServer(Application(),xheaders=True)
    print "Server started on port "+str(options.port)
    http_server.bind(int(options.port), "0.0.0.0")# listen local only "127.0.0.1"
    http_server.start(1)
    tornado.ioloop.IOLoop.instance().start()


if __name__ == '__main__':
    main()

监听0.0.0.0

监听 0.0.0.0

Application的listen方法可以指定ip，比如

app.listen(8888, address="0.0.0.0")
