Linux的双网卡绑定（即bond0）
bond网卡的制作
一：在机其上安装两块网卡，并修改相应的网络配置文件
vim /etc/sysconfig/network-scripts/ifcfg-eth0
DEVICE=eth0
ONBOOT=yes
BOOTPROTO=static
MASTER=bond0
vim /etc/sysconfig/network-scripts/ifcfg-eth1
DEVICE=eth1
ONBOOT=yes
BOOTPROTO=static
MASTER=bond0
vim /etc/sysconfig/network-scripts/ ifcfg-bond0
DEVICE=bond0
ONBOOT=yes
BOOTPROTO=static
IPADDR=IP地址
NETMASK=子网掩码
Modprobe bonding
二。vim /etc/modprobe.conf 加载相关的网卡驱动
开机脚本
三：vim /etc/rc.d/rc.local 增加一行
四：查看状态 cat /proc/net/bonding/bond0并进行测试
使用桥接模式
Ping bond0的ip地址
当中在虚拟机中eth0断开模拟网卡损坏是的情景，可以看到网卡的替换过程，过程十分的短暂
