单进程:
server = HTTPServer(app) server.listen(8888) IOLoop.instance().start()
多进程,方案1:
server = HTTPServer(app) server.bind(8888) server.start(0) # Forks multiple sub-processes IOLoop.instance().start()
多进程,方案2:
sockets = tornado.netutil.bind_sockets(8888) tornado.process.fork_processes(0) server = HTTPServer(app) server.add_sockets(sockets) IOLoop.instance().start()
