How do you run the Tornado web server locally?

Is it possible to run Tornado such that it listens to a local port (e.g. localhost:8000). I can't seem to find any documentation explaining how to do this.

Once you've defined an application (like in the other answers) in a file (for example server.py), you simply save and run that file.

python server.py

Add an address argument to Application.listen() or HTTPServer.listen().

It's documented here (Application.listen) and here (TCPServer.listen).

For example:

application = tornado.web.Application([
    (r'/blah', BlahHandler),
    ], **settings)

# Create an HTTP server listening on localhost, port 8080.
http_server = tornado.httpserver.HTTPServer(application)
http_server.listen(8080, address='127.0.0.1')

If you want to daemonize tornado - use supervisord. If you want to access tornado on address like http://mylocal.dev/ - you should look at nginx and use it like reverse proxy. And on specific port it can be binded like in Lafada's answer.

In the documetaion they mention to run on the specific port like

import tornado.ioloop
import tornado.web

class MainHandler(tornado.web.RequestHandler):
    def get(self):
        self.write("Hello, world")

application = tornado.web.Application([
    (r"/", MainHandler),
])

if __name__ == "__main__":
    application.listen(8000)
    tornado.ioloop.IOLoop.instance().start()

You will get more help from http://www.tornadoweb.org/documentation/overview.html and http://www.tornadoweb.org/documentation/index.html
