Supervisor setup on AWS AMI Linux

Question

I'm trying to get supervisor working to make sure my queue system is always running.

Here are the steps I took, which I pieced together from various sources: (Ran as root or super user)

1. Ran:

   # easy_install supervisor
   # echo_supervisord_conf > /etc/supervisord.conf
   # vi supervisord.conf
   

2. Pasted the following to end of file:

   command=/usr/bin/php /path/to/AppName/artisan --env=production --timeout=240 queue:listen
   

3. Ran:

   # supervisord -c /etc/supervisord.conf
   # supervisorctl
   supervisor> status
   supervisor>
   

   It does not display anything.

4. Ran:

   # service supervisord reload
   supervisord: unrecognized service
   

Answer 1

to get supervisord running as a service you need an /etc/init.d/supervisord file. i used https://raw.githubusercontent.com/Supervisor/initscripts/master/redhat-init-equeffelec with mods to match the path which easy_install put the binaries at (/usr/local/bin/) and to find the pid and logs in /var/run/ and /var/log/

Answer 2

I just spent a couple hours on this, trying to get supervisor and Amazon Linux AMI to play nice. I was experiencing exactly the symptoms you mentioned.

Some quirks:

• go ahead and include -c /etc/supervisord.conf (or whatever your path) on any supervisord or supervisorctl command, and make sure you run from the same user every time.

• in your /etc/supervisord.conf, when you append the command, make sure you prefix the name with 'program:', like so:

  [program:queue]
  command=/usr/bin/php /path/to/AppName/artisan --env=production --timeout=240 queue:listen
  

Once I did the above, supervisorctl FINALLY recognized the queue process/program.

I still haven't gotten sudo service supervisor restart to recognize supervisor as a service - I suspect it's because I don't have an upstart script that I've seen mentioned in a handful of places. Not sure I need one at this point.

Some debugging techniques I used:

• ps aux | grep super to see if it's running
• sudo vim to edit the /etc/supervisord.conf and sudo /usr/local/bin/supervisorctl -c /etc/supervisord.conf then avail, reload, update etc. to update (rather than editing .ebextensions and pushing to elastic beanstalk everytime)
