Configure the Supervisor

Supervisor's configuration file, named Supervisor ord.conf, provides configuration option Settings for Supervisor ord(Supervisor's master service command) and Supervisor orctl(Supervisor's supervisory management command). Supervisor does not specify the location of the configuration file Supervisor ord.conf, and the Supervisor service will start at:

$CWD/supervisord.conf

$CWD/etc/supervisord.conf

/etc/supervisord.conf

These directory locations look up the configuration file overord.conf. Supervisor also provides the parameter "-c" to specify the directory path for the configuration file.

Enter the "echo_supervisor _conf" command at the terminal to view the Supervisor's default configuration.

Generate a default profile:

echo_supervisord_conf > /etc/supervisord.conf

[unix_http_server]

file = /tmp/supervisor.sock

chmod = 0700

 

[supervisord]

logfile = /Users/dengjoe/.supervisor/supervisord.log

logfile_maxbytes = 50MB

logfile_backups=10

loglevel = info

pidfile = /tmp/supervisord.pid

nodaemon = False

minfds = 1024

minprocs = 200

umask = 022

identifier = supervisor

directory = /tmp

nocleanup = true

childlogdir = /tmp

 

[supervisorctl]

serverurl = unix:///tmp/supervisor.sock

 

[rpcinterface:supervisor]

supervisor.rpcinterface_factory = supervisor.rpcinterface:make_main_rpcinterface

 

 

 

[program:shadowsocks]

directory = /Users/dengjoe/shadowsocks

command = /usr/bin/python /Users/dengjoe/shadowsocks/local.py
