class IndexHandler(tornado.web.RequestHandler):

def get(self):

greeting = self.get_argument('greeting','Hello')

self.write(greeting + ',welcome you to read:jk.yunzhongmoke.com')

if __name__ == "__main__":

tornado.options.parse_command_line()

app = tornado.web.Application(handlers=[(r"/",IndexHandler)])

http_server = tornado.httpserver.HTTPServer(app)

http_server.listen(options.port)

tornado.ioloop.IOLoop.instance().start()

完成后在8000端口运行，因为80端口已经运行了nginx服务器。
