在配置文件supervisord.conf中添加应用模块:

directory=/Users/dongsj/workspace/dsj/pythonSpace/flaskEnv/workspace/demoWeb
user=dongsj
stdout_logfile=/Users/dongsj/workspace/dsj/pythonSpace/flaskEnv/workspace/demoWeb/log/supervisor/pkyx.log
stderr_logfile=/Users/dongsj/workspace/dsj/pythonSpace/flaskEnv/workspace/demoWeb/log/supervisor/pkyx_err.log
auto_start=True
auto_restart=True

开启web管理端：

[inet_http_server]         ; inet (TCP) server disabled by default
port=127.0.0.1:9999        ; (ip_address:port specifier, *:port for all iface)
