1 先写一个脚本, 这个脚本用来启动你的程序, 或者停止你的程序, 可参考如下
--------------------
#! /bin/sh

? exit $RETVAL

--------------------
这个服务是smartd, 你也可以参考/etc/init.d目录下的脚本, 基本都差不多


2 将写好的脚本放入/etc/init.d目录

3 用命令service xxx start/stop/restart就可以执行了

4 如果你想在开机的时候,就启动你的服务, 那么你需要对你的配置文件进行配置
见上面的例:

# chkconfig: 2345 40 40

不要以为这一行市注释, 其实不尽然
如果执行#chkconfig service_name on/off?
就会在/etc/rc.dx相应的目录中 添加/删 除启动关闭项, 用于在系统启动和关闭时的自动启动和关闭
这里将在/etc/rc.d2,3,4,5目录下 添加/删除, 后面的40 40分别是启动顺序和关闭顺序
也就意味着系统在处于2,3,4,5模式下时, 会启动你的程序

不说得是否清楚
