- Starting Supervisor daemon manager...
Error: Another program is already listening on a port that one of our HTTP servers is configured to use. Shut this program down first before starting supervisord.
For help, use /usr/bin/supervisord -h
...fail!
解决：
find / -name supervisor.sock
unlink /***/supervisor.sock

可以先尝试增加directory配置，避免环境问题导致。
