1.将bwService文件放到 /etc/init.d/下
bwService文件(类型是文件)

相关命令
[root@localhost ~]# cd /etc/init.d/ [root@localhost init.d]# rz [root@localhost init.d]# ls bwService functions netconsole network README
2.bwService赋予执行权限
[root@localhost init.d]# chmod +x bwService
3.添加bwService到centos服务里
[root@localhost init.d]# chkconfig --add bwService
4.创建相关软连接
[root@localhost init.d]# ln -s /etc/init.d/bwService /etc/rc0.d/K03bwService [root@localhost init.d]# ln -s /etc/init.d/bwService /etc/rc1.d/K03bwService [root@localhost init.d]# ln -s /etc/init.d/bwService /etc/rc2.d/S98bwService [root@localhost init.d]# ln -s /etc/init.d/bwService /etc/rc3.d/S98bwService [root@localhost init.d]# ln -s /etc/init.d/bwService /etc/rc4.d/S98bwService [root@localhost init.d]# ln -s /etc/init.d/bwService /etc/rc5.d/S98bwService
5.查看服务状态,开启服务
[root@localhost init.d]# service bwService status 交换机服务 [停止运行] 网站服务 [停止运行] [root@localhost init.d]# service bwService start 启动交换机服务: [ OK ] 启动网站服务: [ OK ] [root@localhost init.d]#
