[program:jupyter]
; 用哪个用户启动
user= jupyter

; 程序的启动目录
directory = /home/jupyter/.jupyter
; 启动命令
command = /home/jupyter/.jupyter/start.sh

; stdout 日志文件，需要注意当指定目录不存在时无法正常启动，所以需要手动创建目录（supervisord 会自动创建日志文件）
stdout_logfile = /data/app_log/jupyter_stdout.log
stderr_logfile = /data/app_log/jupyter_stderr.log
需配置environment

http://supervisord.org/subprocess.html#subprocess-environment

No shell is executed by supervisord when it runs a subprocess, so environment variables such as USER, PATH, HOME, SHELL, LOGNAME, etc. are not changed from their defaults or otherwise reassigned. This is particularly important to note when you are running a program from a supervisord run as root with a user= stanza in the configuration. Unlike cron, supervisord does not attempt to divine and override “fundamental” environment variables like USER, PATH, HOME, and LOGNAME when it performs a setuid to the user defined within the user= program config option. If you need to set environment variables for a particular program that might otherwise be set by a shell invocation for a particular user, you must do it explicitly within the environment= program config option. An example of setting these enviroment variables is as below.
