vim /etc/modprobe.d/bonding.conf
#追加

alias bond0 bonding

options bonding mode=0 miimon=200

加载模块(重启系统后就不用手动再加载了)

# modprobe bonding

确认模块是否加载成功：

[root@test ~]# lsmod | grep bonding
bonding 100065 0

重启网络，然后确认一下状况：

[root@test ~]# /etc/init.d/network restart

[root@test ~]# cat /proc/net/bonding/bond0


vim /etc/init.d/after.local
#!/bin/sh
ifenslave bond0 eth0 eth1

chmod 700 /etc/init.d/after.local

ethtool

ifconfig eth0 down(无输出)
