Linux中service命令和/etc/init.d/的关系
service xxx启动 /etc/init.d/ 目录下的xxx脚本
如一个脚本名为 mysvc保存在/etc/init.d/下可以用 service mysvc 运行mysvc脚本
echo passed in option $0 $1

if [ $1 = "start" ]
then
        echo myservice started........................................
elif [ $1 = "stop" ]
then
        echo myservice stoped........................................
else
        echo myservice not supported option........................................

fi

[root@localhost init.d]# service mysvc start
passed in option /etc/init.d/mysvc start
myservice started........................................

[root@localhost init.d]# service mysvc stop
passed in option /etc/init.d/mysvc stop
myservice stoped........................................

[root@localhost init.d]# service mysvc xxx
