ERROR (no such process) Nginx+Gunicorn+Supervisord

Question

if I run command (to start the app) via supervisor:

sudo supervisorctl start myapp

it is throwing the error of:

myapp: ERROR (no such process) 

I created a file called myappsettings.conf:

[program:myapp]
command = /usr/local/bin/gunicorn -c /home/ubuntu/virtualenv/gunicorn_config.py myapp.wsgi
user = ubuntu
stdout_logfile = /home/ubuntu/virtualenv/myapp/error/gunicorn_supervisor.log
redirect_stderr = true

What is the issue here?

Thank you.

Answer 1

Try:

supervisorctl reread
supervisorctl reload

That should start the service. I did this as root under Ubuntu 13.04.

EDIT:

I've had trouble since I posted this with SIGHUP'ing Supervisor processes. I would just like to share a little snippet I found elsewhere:

sudo kill -HUP `sudo supervisorctl status | grep $APP_NAME | sed -n '/RUNNING/s/.*pid \([[:digit:]]\+\).*/\1/p'`

The below will send a SIGHUP to the process running APP_NAME. This is useful for Gunicorn graceful reloading.

Wow... really did they have to NOT put this in the documentation? Thanks a bunch for your answer! – Sanctus

The problem is that this will restart all supervised processes, while restart command is meant to restart a single one. – Bluepoint

The issue was with the reading of the config files. Its not a great option on a live system. – Edmon

Answer 2

The name of the gunicorns's process in supervisor is different from the name of gunicorn in truth which can be confusing, to reset gunicorn using supervisor use

sudo supervisorctl restart guni:gunicorn
