[root@oracle network-scripts]# vim /etc/modprobe.conf
在該文件的最下面添加如下2行
alias bond0 bonding
options bond0 miimon=100 mode=1
注 :
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，常用的爲0,1兩種。
mode=0表示load balancing (round-robin)爲負載均衡方式，兩塊網卡都工作。
mode=1表示fault-tolerance (active-backup)提供冗餘功能，工作方式是主備的工作方式,也就是說默認情況下只有一塊網卡工作,另一塊做備份.
[root@oracle network-scripts]# vim /etc/rc.local
添加如下2行
ifenslave bond0 eth0 eth1
route add -net 10.2.34.0 netmask 255.255.255.0 bond0
