Supervisor and Environment Variables

问题

I really don\'t know how to get supervisor to work with environment variables.

Below is a configuration snippet.

[program:htNotificationService]
priority=2
#autostart=true
#autorestart=true
directory=/home/ubuntu/workspace/htFrontEnd/heythat/htsite
command = /usr/bin/python htNotificationService.py -service
stdout_logfile=/var/log/heythat/htNotificationService.log
redirect_stderr=true
environment=PATH=/home/ubuntu/workspace/htFrontEnd/heythat
stopsignal=QUIT

I have tried the following:

environment=PATH=/home/ubuntu/workspace/htFrontEnd/heythat
environment=PYTHONPATH=$PYTHONPATH:/home/ubuntu/workspace/htFrontEnd/heythat
environment=PATH=/home/ubuntu/workspace/htFrontEnd/heythat,PYTHONPATH=$PYTHONPATH:/home/ubuntu/workspace/htFrontEnd/heythat

When I start supervisor I get

htNotificationService: ERROR (abnormal termination)

I can start from the shell by setting the python path, but not from supervisor. In the logs I get an error that says that an import can\'t be found. Well, that would be solved if supervisor would work. I even have the path in /etc/environments?

Why will supervisor not work?

Referencing existing env vars is done with %(ENV_VARNAME)s

( see https://github.com/Supervisor/supervisor/blob/master/supervisor/skel/sample.conf )

Setting multiple environment variables is done by separating them with commas

( see http://supervisord.org/subprocess.html#subprocess-environment )

Try:

environment=PYTHONPATH=/opt/mypypath:%(ENV_PYTHONPATH)s,PATH=/opt/mypath:%(ENV_PATH)s

In your .conf file under the supervisord block, you can add all the environment key=value pairs as such

[supervisord]
environment=CELERY_BROKER_URL="amqp://guest:guest@127.0.0.1:5672//",FLASK_CONFIG="TESTING"

[program:celeryd]
command=celery worker -A celery --loglevel=info -P gevent -c 1000

If you dont want to hardcode the variables but want to pull it in from the os environment, step 1 on your bash

Export env var

>> sudo export CELERY_BROKER_URL="amqp://guest:guest@127.0.0.1:5672//"

Reload Bash

>> . ~/.bashrc

Check if env vars are set properly

>> env

Now modify the conf file to read - Note: prepend your env variables with ENV_

[supervisord]
environment=CELERY_BROKER_URL="%(ENV_CELERY_BROKER_URL)s",FLASK_CONFIG="%(ENV_FLASK_CONFIG)s"

[program:celeryd]
command=celery worker -A celery --loglevel=info -P gevent -c 1000

this works for me. note the tabs before each line:

environment=
    CLOUD_INSTANCE_NAME=media-server-xx-xx-xx-xx,
    CLOUD_APPLICATION=media-server,
    CLOUD_APP_COMPONENT=none,
    CLOUD_ZONE=a,
    CLOUD_REGION=b,
    CLOUD_PRIVATE_IP=none,
    CLOUD_PUBLIC_IP=xx.xx.xx.xx,
    CLOUD_PUBLIC_IPV6=xx.xx.xx.xx.xx.xx,
    CLOUD_PROVIDER=c

If you install supervisor from a package installer, check which Supervisor version you are using. As of August 2016 you will get 3.0b2. If this is the case you will need a newer version of supervisor. You can get it by installing supervisor manually or by using Python's pip. Make sure all the dependencies are met, along with the upstart setup so that supervisord works as a service and starts on system boot.
