如何为 django-supervisor 编写初始化脚本

请原谅，这是我第一次尝试为 centos 5 编写初始化脚本。

我正在使用 django + Supervisor 来管理我的 celery 工作者和调度程序。

现在，这是我天真的简单尝试/etc/init.d/supervisor

#!/bin/sh
#
# /etc/rc.d/init.d/supervisord
#
# Supervisor is a client/server system that
# allows its users to monitor and control a
# number of processes on UNIX-like operating
# systems.
#
# chkconfig: - 64 36
# description: Supervisor Server
# processname: supervisord

# Source init functions

/home/foo/virtualenv/property_env/bin/python /home/foo/bar/manage.py supervisor --daemonize

在我的supervisor.conf中：

[program:celerybeat]
command=/home/property/virtualenv/property_env/bin/python manage.py celerybeat --loglevel=INFO --logfile=/home/property/property_buyer/logfiles/celerybeat.log

[program:celeryd]
command=/home/foo/virtualenv/property_env/bin/python manage.py celeryd --loglevel=DEBUG --logfile=/home/foo/bar/logfiles/celeryd.log --concurrency=1 -E

[program:celerycam]
command=/home/foo/virtualenv/property_env/bin/python manage.py celerycam

我无法让它工作。

2013-08-06 00:21:03,108 INFO exited: celerybeat (exit status 2; not expected)
2013-08-06 00:21:06,114 INFO spawned: 'celeryd' with pid 11772

2013-08-06 00:21:06,147 INFO gave up: celerycam entered FATAL state, too many start retries too quickly
2013-08-06 00:21:06,147 INFO exited: celeryd (exit status 2; not expected)

2013-08-06 00:21:07,153 INFO gave up: celerybeat entered FATAL state, too many start retries too quickly

我相信这是初始化脚本，但请帮助我了解哪里出了问题。

有一份文档涵盖了您所需要的全部内容；最好仔细阅读，它位于以下位置：

[alexus@wcmisdlin02 ~]$ ll /usr/share/doc/initscripts-*/

-rw-r--r--. 1 root root  6357 Oct 10  2013 sysvinitfiles
[alexus@wcmisdlin02 ~]$

但对于初学者来说，似乎至少你缺少start()一些stop()子功能（允许你启动或停止服务）。

或者您可以尝试以下操作：用户贡献的 Supervisor 操作系统初始化脚本 -Supervisor/initscripts · GitHub
