提问:
我自己开发了一个绑定端口的daemon程序,想加到centos的服务中,这样我就可以使用service start这样的命令启动了。请问,我该如何添加到service当中?
回答:
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# Copyright (C) 2002-4 Bruce Allen# $Id: smartd.initd,v 1.2 2004/09/17 11:55:28 arjanv Exp $# For RedHat and cousins:# chkconfig: 2345 40 40# description: Self Monitoring and Reporting Technology (SMART) Daemon# processname: smartd# This program is free software; you can redistribute it and/or modify it# under the terms of the GNU General Public License as published by the Free# Software Foundation; either version 2, or (at your option) any later# version.# You should have received a copy of the GNU General Public License (for# example COPYING); if not, write to the Free Software Foundation, Inc., 675# Mass Ave, Cambridge, MA 02139, USA.# This code was originally developed as a Senior Thesis by Michael Cornwell# at the Concurrent Systems Laboratory (now part of the Storage Systems# Research Center), Jack Baskin School of Engineering, University of# California, Santa Cruz. http://ssrc.soe.ucsc.edu/.# 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/rc.d/init.d目录下的脚本, 基本都差不多
2.将写好的脚本放入/etc/rc.d/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第7、8行:# chkconfig: 2345 40 40# description: Self Monitoring and Reporting Technology (SMART) Daemon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
