RHEL6 Installing Python Packages tornado

Tornado is a full-stack (full-stack) Web framework and asynchronous network library developed using Python, originally developed by FriendFeed. By using non-blocking io,tornado, you can handle tens of thousands of open connections, which are long polling, websockets, and others that need to be used to maintain long-connected applications for your users.

Unlike other major Web server frameworks (primarily the Python framework), Tornado uses epoll non-blocking IO, which responds quickly and handles thousands of of concurrent connections, especially for real-time Web services. The Tornado is divided into four main parts:

• Web Framework (includes RequestHandler, base class for creating Web programs, and various support classes)

• Implements the client and server side of HTTP (Httpserver and Asynchttpclient).

• An asynchronous network library (Ioloop and IOStream)

• A co-Libraries (Tornado.gen) that allows the asynchronous calling code to write in a more straightforward way instead of a callback link

One of the simplest Web services:

Import Tornado.ioloopimport tornado.webclass MainHandler (tornado.web.RequestHandler): Def get (self): Self.write ( "Hello, World") application = Tornado.web.Application ([(R "/", MainHandler),]) if __name__ = = "__main__": Application. Listen (8888) tornado.ioloop.IOLoop.instance (). Start ()
