Questions[paster](server)

I am attempting to daemonize a paster process which launches celeryd.

celeryd is a paster script that only exists within the python virtual environment.

I have no problem with paster serve, as that can daemonize itself. celeryd does not have this ability coded (as the developer has not included it) and it is recommended to use an init script that had been contributed to the project. However, I am unsure how to integrate the need for the virtual environment and paster into this script.

How do I have a paster celeryd process daemonize itself?

Thanks.

[update] I eventually simply opted to drop the process to the background using &. I'm working out the command syntax for handling this in an init script. You must send a SIGINT signal (try kill -SIGINT $(cat /var/run/celeryd.pid)) to the paste process for it to perform the warm shutdown (properly shutting down the celeryd instance that is spawned by marcin's paste script celeryd (yes, it's a bit confusing).

I am setting up CKAN, a pylons application according to these instructions: http://packages.python.org/ckan/deployment.html

But when I point to the server (no DNS setup yet) using IP or hostname, I only see apache's greeting page, sugesting the ckan app is not being loaded.

here is my mod_wsgi script:

import os
instance_dir = '/home/flavio/var/srvc/ckan.emap.fgv.br'
config_file = 'ckan.emap.fgv.br.ini'
pyenv_bin_dir = os.path.join(instance_dir, 'pyenv', 'bin')
activate_this = os.path.join(pyenv_bin_dir, 'activate_this.py')
execfile(activate_this, dict(__file__=activate_this))
from paste.deploy import loadapp
config_filepath = os.path.join(instance_dir, config_file)
from paste.script.util.logging_config import fileConfig
fileConfig(config_filepath)
application = loadapp('config:%s' % config_filepath)

here is my virtual host configuration:

<VirtualHost *:80>

ServerName dck093

ServerAlias dck093

WSGIScriptAlias / /home/flavio/var/srvc/ckan.emap.fgv.br/pyenv/bin/ckan.emap.fgv.br.py

I try to disable the 000-default site (with a2dissite), but that dind't help.After doing this I get an Internal server error page, but no log message. Can anyone point out what am I missing?

I want to map a particular domain in nginx, and then have nginx round-robin to a list of servers that will response to http requests.

So I have nginx for www.domain1.com

Its a python application, and I have 10 instances of paste running on different ports that I want nginx to forward/proxy requests to using round-robin.

can it do this, if yes, how?
