Ubuntu server wewerfsre instrumentation with Upstart, Gunicorn & Django
published on
Create the init script for upstart in /etc/init/upstart-job.conf
PORT=8002 must match the number you configured in server configuration. In case you are running multiple websites on the same machine you’ll have to increment this number accordingly.
As a rule-of-thumb set the –workers (NUM_WORKERS) according to the following formula: 2 * CPUs + 1. The idea being, that at any given time half of your workers will be busy doing I/O. For a single CPU machine it would give you 3.
Add new system service
# sudo ln -fs /etc/init/upstart-job.conf /etc/init.d/upstart-job
Make it starts at system boot
# sudo update-rc.d upstart-job defaults
And start it now
# sudo service upstart-job start
