I want to create a twisted daemon from my application: ...
You want to use twistd. See http://twistedmatrix.com/documents/current/core/howto/basics.html#auto1
The process is roughly:
1) create a myapp.tac file which essentially loads in your server and wraps it in an application 2) run something like: $ twistd -r epoll -y myapp.tac which will daemonize your server (using the epoll reactor) and write its pid to twistd.pid
A .tac file could look something like:
from twisted.application import service, internet from myapp import MyAppServer
def get_service(): """ Return a service suitable for creating an application object. """ site = MyAppServer() port = 2000 return internet.TCPServer(2000, site)
application = service.Application('MyApplicationName') # attach the service to its parent application service = get_service() service.setServiceParent(application)
Also, keep in mind you might want to use twistd in conjunction with a process runner (http://dustin.github.com/2010/02/28/running-processes.html). That is, if you're using something like Ubuntu, you probably want to run twistd using upstart.
Hope this helps.
Reza
