建立channel bonding interface
#vi /etc/sysconfig/network-scripts/ifcfg-bond0

DEVICE=bond0
BOOTPROTO=none
IPADDR=172.16.251.171
NETMASK=255.255.255.128
GATEWAY=172.16.251.1
DNS1=172.16.251.200
ONBOOT=yes
USERCTL=no
ARPCHECK=no

修改网卡eth0配置
#vi /etc/sysconfig/network-scripts/ifcfg-eth0
输入下面内容
DEVICE="eth0"
BOOTPROTO=none
#ONBOOT="no"
ONBOOT=yes
MASTER=bond0
SLAVE=yes
USERCTL=no

修改网卡eth1配置
#vi /etc/sysconfig/network-scripts/ifcfg-eth1
DEVICE="eth1"
BOOTPROTO=none
#ONBOOT="no"
ONBOOT=yes
MASTER=bond0
SLAVE=yes
USERCTL=no

添加bond0模块
modprobe bonding

#ifconfig bond0 down

配置miimon
#echo 100 > /sys/class/net/bond0/bonding/miimon

配置mode
#echo 1 > /sys/class/net/bond0/bonding/mode

#ifconfig bond0 up

#vi /etc/rc.d/rc.local
加入下列：
modprobe bonding miimon=100 mode=1 primary=eth0
ifenslave bond0 eth0 eth1

#chkconfig NetworkManager off
#service NetworkManager stop
#chkconfig network
#service network restart

#/etc/rc.d/init.d/network restart
