How to use CherrPy as Web server and Bottle as Application to support multiple virtual hosts?

Question

I have a website (which running in Amazon EC2 Instance) running Python Bottle application with CherryPy as its front end web server.

Now I need to add another website with a different domain name already registered. To reduce the cost, I want to utilize the existing website host to do that.

Obviously, virtual host is the solution.

I know Apache mod_wsgi could play the trick. But I don't want to replace CherryPy.

I've googled aa lot, there are some articles showing how to make virtual hosts on CherryPy, but they all assume Cherrypy as Web Sever + Web application, Not CherrPy as Web server and Bottle as Application.

How to use CherrPy as Web server and Bottle as Application to support multiple virtual hosts?

Answer 1

As you mentioned, use VirtualHost . In the example cherrypy.Application instances are used, but any WSGI callable (eg Bottle app) will do.

Answer 2

也许您可以简单地将nginx用作反向代理，并将其配置为将流量发送到正确上游的两个域（cherryPy Web服务器）。

Answer 3

Another idea would be to use Nginx ( http://wiki.nginx.org/Main ) with uWsgi( http://projects.unbit.it/uwsgi/ ) & (uWsgi-python) plug-in

uWsgi has a module named emperor that you can link vhosts(vassals) in, sort of.

i'm a newbie at this myself, so not necessarily an answer but rather a suggestion to check it out. just a heads up, uWsgi and Nginx can be a hassle to get it to work, depending on your linux distro. Does work nicely with bottle, tested it myself. hope it helps

Answer 4

jwalker's answer is pretty clear. In case any CherryPy newbie need whole script for reference, I post one below.

import cherrypy
from bottle import Bottle
import os


app1 = Bottle() 
app2 = Bottle()

@app1.route('/')
def homePage():    
    return "=========  home1 ==============="


@app2.route('/')
def homePage_2():    
    return "=========  home2 ==============="

vhost = cherrypy._cpwsgi.VirtualHost(None, 
                                     domains={
                                              'www.domain1.com': app1, 
                                              'www.domain2.com': app2,
                                             }
                                     )

cherrypy.tree.graft(vhost) 

cherrypy.config.update({
                        'server.socket_host': '192.168.1.4',
                        'server.socket_port': 80,
                      })
cherrypy.engine.start()
cherrypy.engine.block()

you could make www.domain1.com and www.domain1.com point to one IP adress of you server, so it servers for 2 domain in one Web Server.
