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

# smartmontools init file for smartd

# For RedHat and cousins:
# chkconfig: 2345 40 40

# processname: smartd

# Uncomment the line below to pass options to smartd on startup.
# Note that distribution specific configuration files like
# /etc/{default,sysconfig}/smartmontools might override these
#smartd_opts="--interval=1800"

SMARTD_BIN=/usr/sbin/smartd

# Source function library
. /etc/rc.d/init.d/functions

[ -r /etc/sysconfig/smartmontools ] && . /etc/sysconfig/smartmontools

[ ! -f /etc/smartd.conf ] && smartd-conf.py > /etc/smartd.conf

RETVAL=0

prog=smartd

case "$1" in
start)
echo -n $"Starting $prog: "
daemon $SMARTD_BIN $smartd_opts
touch /var/lock/subsys/smartd
echo
exit 0
;;
stop)
echo -n $"Shutting down $prog: "
killproc $SMARTD_BIN
rm -f /var/lock/subsys/smartd
echo
;;
reload)
echo -n $"Reloading $prog daemon configuration: "
killproc $SMARTD_BIN -HUP
RETVAL=$?
echo
;;
report)
echo -n $"Checking SMART devices now: "
killproc $SMARTD_BIN -USR1
RETVAL=$?
echo
;;
restart)
$0 stop
$0 start
;;
status)
status $prog
;;
*)
echo $"Usage: $0 {start|stop|reload|report|restart|status}"
RETVAL=1
esac

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
