我建议你看看upstart如果你在Ubuntu上。它比inittab
好,但确实涉及一些学习曲线。
编辑(作者:布莱尔):这里是我最近为自己的程序编写的新贵剧本的一个改编的例子。像这样一个基本的新贵脚本虽然(像许多这样的事情)是相当可读/可理解的,但当你开始做一些花哨的事情时它们会变得复杂。
description "mydaemon - my cool daemon"
# Start and stop conditions. Runlevels 2-5 are the
# multi-user (i.e, networked) levels. This means
# start the daemon when the system is booted into
# one of these runlevels and stop when it is moved
# out of them (e.g., when shut down).
start on runlevel [2345]
stop on runlevel [!2345]
# Allow the service to respawn automatically, but if
# crashes happen too often (10 times in 5 seconds)
# theres a real problem and we should stop trying.
respawn
respawn limit 10 5
# The program is going to daemonise (double-fork), and
# upstart needs to know this so it can track the change
# in PID.
expect daemon
# Set the mode the process should create files in.
umask 022
# Make sure the log folder exists.
pre-start script
mkdir -p -m0755 /var/log/mydaemon
end script
# Command to run it.
exec /usr/bin/python /path/to/mydaemon.py --logfile /var/log/mydaemon/mydaemon.log

如果你也使用[python-daemon](https://pypi.python.org/pypi/python-daemon/),那么请注意'expect守护进程'节最好避免 - python-daemon将会出现你正在使用暴发户,并不会双叉。 – 2013-06-19 13:21:47
