2.查看bond接口配置

（1）[[email protected] network-scripts]# cat ifcfg-bond0 

DEVICE=bond0

ONBOOT=yes

TYPE=Ethernet

BOOTPROTO=static

IPADDR=192.168.40.40

NETWORK=192.168.40.0

NETMASK=255.255.255.0

BROADCAST=192.168.40.255

GATEWAY=192.168.40.254

USERCTL=NO

（2）[[email protected] network-scripts]# cat ifcfg-eth2

DEVICE=eth2

HWADDR=90:E2:BA:73:49:52

TYPE=Ethernet

UUID=7431769c-f1d9-41bc-8e8a-fa702a355296

ONBOOT=yes

NM_CONTROLLED=yes

BOOTPROTO=none

MASTER=bond0

SLAVE=yes

USERCTL=no

（3）[[email protected] network-scripts]# cat ifcfg-eth3

DEVICE=eth3

HWADDR=90:E2:BA:73:49:53

TYPE=Ethernet

UUID=496784dc-b5f5-4b50-8cb8-72eec3fdea3c

ONBOOT=yes

NM_CONTROLLED=yes

MASTER=bond0

SLAVE=yes

BOOTPROTO=none

IPV6INIT=no

USERCTL=no

[[email protected] network-scripts]# 

3.设置bond模式

[[email protected] network-scripts]# cat /etc/modprobe.d/bonding.conf 

alias eth2 pcnet32

alias scsi_hostadapter mptbase

alias scsi_hostadapter1 mptscsih

alias eth3 pcnet32

alias bond0 bonding

options bond0 miimon=100 mode=1

[[email protected] network-scripts]# 

4.设置开机启动接口

[[email protected] network-scripts]# cat /etc/rc.d/rc.local 

#!/bin/sh

#

# This script will be executed *after* all the other init scripts.

# You can put your own initialization stuff in here if you don‘t

# want to do the full Sys V style init stuff.

touch /var/lock/subsys/local

route add -net 192.168.10.0/24 gw 192.168.10.254 dev eth0

route add -net 192.168.20.0/24 gw 192.168.20.254 dev eth1

route add -net 192.168.1.0/24 gw 192.168.10.254 

route add -net 0.0.0.0/0 gw 192.168.20.254 metric 20

ifenslave bond0 eth2 eth3
