单个网卡操作 [[email protected] ~]# ifdown eth0 #关闭网络 [[email protected] ~]# ifup eth0 #启动网络 网络服务: [[email protected] ~]# service network stop #关闭网络服务 [[email protected] ~]# service network start #启动网络服务 [[email protected] ~]# service network restart #重启网络服务 [email protected] ~]# service network status #查看网卡状态
