Run a python script with supervisor

Question

I copied from here to run my Python code as a daemon. For extra uptime. I thought it would be a better Idea to use supervisor to keep this daemon running.

我这样做了。 python_deamon.conf

[program:python_deamon]
directory=/usr/local/python_deamon/
command=/usr/local/python_venv/bin/python daemon_runnner.py start
stderr_logfile=/var/log/gunicorn.log
stdout_logfile=/var/log/gunicorn.log
autostart=true
autorestart=true

问题是，尽管主管成功启动了 python_daemon，但它一直在重试。

2015-09-23 16:10:45,592 CRIT Supervisor running as root (no user in config file)

只是为了记录后覆盖 run() method I never return anything.

有可能做我想做的事情还是我很笨？

PS：我知道整个问题的根本原因是因为 run() 从不返回任何内容，主管一直在尝试启动它，因此认为该过程失败并给出状态为 FATAL Exited too quickly (process log may have details).

我的实际问题是我做得对吗？或者可以这样做吗？

PPS：独立（没有主管）daemon_runnner.py在有和没有 sudo 权限的情况下都可以正常运行。

尝试设置 startsecs = 0：

[program:foo]
command = ls
startsecs = 0
autorestart = false
http://supervisord.org/configuration.html

startsecs

启动后程序需要保持运行以认为启动成功的总秒数。如果程序在启动后没有停留这么多秒，即使它以“预期的”退出代码（参见退出代码）退出，也会认为启动失败。设置为 0 表示程序不需要在任何特定的时间内保持运行。
