编辑eth1网卡
[root@ ~]# cd /etc/sysconfig/network-scripts/ [root@ network-scripts]# cat >ifcfg-eth1 <编辑eth2网卡
[root@ network-scripts]# cat >ifcfg-eth2 <编辑bind0网卡
[root@ network-scripts]# cat >ifcfg-bind0 <配置bond参数
[root@ network-scripts]# cat >/etc/modprobe.conf <加入开机自启动(/etc/rc.local)
[root@ network-scripts]# cat >>/etc/rc.local <重启网络服务
