; This is where you run individual Tornado instances.
; We run four; one per processor core.
; In development, we ran as many as four per core with no issues.
; If you're looking to minimize cpu load, run fewer processes.
; BTW, Tornado processes are single threaded.
; To take advantage of multiple cores, you'll need multiple processes.

Have you created a startup script to utilize this? I solved this without supervisor using standard bash techniques, but am considering porting my solution over to supervisor based but need to be able to start on sever restart via chkconfig on centos.

@hunt3r: I solve the problem i believe you are having, by doing the following (am currently using the Amazon Linux AMI on EC2 which is loosely based on CentOS):

all as root user:

1. create a virtualenv for supervisor
2. activate virtualenv and install supervisor via pip
3. write the main supervisord.conf file to /etc/supervisord.conf
4. optionally create dir /etc/supervisord.d and put supervisor configs in there (all of my configs have user var specified as non-root user)
5. save the following to /etc/init.d/supervisord:

!/bin/sh

6. chmod +x /etc/init.d/supervisord
7. chkconfig —add supervisord
8. chkconfig supervisord on
9. service supervisord start

Hope this helps!
