2、編輯物理網路介面卡配置文件,不指定網卡IP（實例如下）
Cat /etc/sysconfig/network-scripts/ifcfg-eth0
DEVICE=eth0
ONBOOT=yes
BOOTPROTO=none
Cat /etc/sysconfig/network-scripts/ifcfg-eth1
DEVICE=eth1
ONBOOT=yes
BOOTPROTO=none
3、編輯 /etc/modprobe.conf 文件,加入如下一行內容,以使系統在啟動時載入bonding模塊,對外虛擬網路介面設備為 bond0
alias bond0 bonding
options bond0 miimon=100 mode=1
說明：miimon是用來進行鏈路監測的. 比如:miimon=100,那麼系統每100ms監測一次鏈路連接狀態,如果有一條線路不通就轉入另一條線路；mode的值表示工作模式,他共有0,1,2,3四種模式,常用的為0,1兩種.
mode=0表示load balancing (round-robin)為負載均衡方式,兩塊網卡都工作.
4、編輯 /etc/rc.d/rc.local
加入兩行
ifenslave bond0 eth0 eth1
route add -net 0.0.0.0 netmask 0.0.0.0 bond0
5、重啟伺服器或service network restart
Bringing up interface bond0 OK
6、重啟后查看網卡信息
[root@yest ~]# ifconfig
