Tornado Web server multi process startup 2 methods

Introduction to Tornado

Tornado is an open source version of FriendFeed's Web server and its popular tools. Tornado has a clear difference from today's mainstream Web server frameworks (including most Python frameworks) : it's a non-blocking server, and it's pretty fast. With its non-blocking approach and use of epoll, Tornado can handle thousands of connections per second, making Tornado an ideal framework for real-time Web services.

Two, multi - process startup method

Normal startup method:

server = HTTPServer(app)

server.listen(8888)

IOLoop.instance().start()

Multi-process, plan 1:

server = HTTPServer(app)

server.bind(8888)

server.start(0)  # Forks multiple sub-processes

IOLoop.instance().start()

Multi-process, plan 2:

sockets = tornado.netutil.bind_sockets(8888)

tornado.process.fork_processes(0)

server = HTTPServer(app)

server.add_sockets(sockets)

IOLoop.instance().start()
