自己的第一个服务启动脚本，虽然很简单和粗糙---httpd服务启动脚本

#!/bin/bash  //第一行的#号是注释，其他的#号开头的不是注释

# chkconfig: 2345 55 25   //运行级别，开机启动优先权，关闭优先权

# description: httpd  is a protocol for web service. //关于服务的描述

#              This service starts up the httpd server daemon.

#

# processname: httpd  //进程名称

下面是脚本内容

service=httpd

servicedir=/usr/local/apache2/bin

start () {

        $servicedir/apachectl start

        touch /usr/local/apache2/bin/lock

        echo "$service is running..."

}

stop () {

         $servicedir/apachectl stop

        rm -rf  /usr/local/apache2/bin/lock

        echo "$service is stopped"

}

status () {

        if [ -f /usr/local/apache2/bin/lock ];then

                echo "$service is running....."

        else

                echo "$service is stopped"

        fi

}

restart () {

        stop

        start

}

case "$1" in

        start ;;

        status;;

        restart;;

*)

        echo "$0: usage start|stop|status|restart"
