supervisord : 启动supervisor
supervisorctl reload :修改完配置文件重启supervisor
supervisorctl status :查看supervisor监管的进程状态
supervisorctl start 进程名：启动XXX进程名
supervisorctl stop 进程名：停止进程名
supervisorctl stop all停止全部进程，注：start、restart、stop都不会载入最新的配置文件
supervisorctl update 根据最新的配置文件，启动新配置或有改动的进程，配置没有改动的进程不会受影响而重启
edit /etc/supervisor/supervisor.conf program sandbox point to script file
make file /var/log/supervisor.log
supervisord -c /etc/supervisor/supervisor.conf
supervisorctl -c /etc/supervisor/supervisor.conf
if some error like this:
supervisord -c /etc/supervisor/supervisor.conf
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
follow command may work:
sudo unlink /tmp/supervisor.sock
sudo unlink /var/run/supervisor.sock
supervisor.conf
; Sample supervisor config file.

; For more information on the config file, please see:

;
; Notes:
; - Shell expansion ("~" or "$HOME") is not supported. Environment
; variables can be expanded using this syntax: "%(ENV_HOME)s".
; - Quotes around values are not supported, except in the case of
; the environment= options as shown below.
; - Comments must have a leading space: "a=b ;comment" not "a=b;comment".
; - Command will be truncated if it looks like a config file comment, e.g.
; "command=bash -c 'foo ; bar'" will truncate to "command=bash -c 'foo ".
