linux 双网卡bond命令,Linux的双网卡绑定（即bond0）[通俗易懂]

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
