supervisorctl reread
error: <class ‘socket.error‘>, [Errno 111] Connection refused: file: /usr/lib64/python2.6/socket.py line: 56
You have to start supervisord before you can use supervisorctl. In my case:
supervisord -c /etc/supervisor/supervisord.conf
supervisorctl -c /etc/supervisor/supervisord.conf
