CentOS Tornado server installation tutorial

Centos Tornado Server Installation Tutorial

 

Install using repository

yum install python-tornado

 

First ‘Hello World’ App

I’ve copied the hello world sample from Tornado documentation:

Create a new file called ‘hello.py‘ (or any other name) and fill it with:

1
2
3
4
5
6
7
8
9
10
11
12
13
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(8888)
   tornado.ioloop.IOLoop.instance().start()
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(8888)
   tornado.ioloop.IOLoop.instance().start()

Now start your server with simply typing at bash:

1
python hello.py
python hello.py

Now you can visit ‘127.0.0.1:8888‘ to watch your hello world first torando app.

It should return the ‘Hello, world‘ output into your browser.

 

Nginx

Good implementation of your server would be behind nginx server, where you can run multiple instances of your app on different port and serve them all throw port 80 using nginx load balancer.

After you know how to start a torando server, you can jump into the documentation and learn how-to build your first Torando server!
