Linux下設定網路卡繫結 (final)

 

eth0 及eth2 繫結為 bond0 
eth1 及eth3 繫結為 bond1  

 

[root@wsjrac03 network-scripts]# cp  ifcfg-eth0  ifcfg-bond0

[root@wsjrac03 etc]# cat modprobe.conf

alias bond0 bonding
options bond0 miimon=100 mode=1  primary=eth0
alias bond1 bonding
options bond1 miimon=100 mode=1  primary=eth1  

 

 

[root@wsjrac03 etc]# vi /etc/rc.local

touch /var/lock/subsys/local
ifenslave bond0 eth0 eth2
ifenslave bond1 eth1 eth3

 

 

重新啟動後檢視 ：

下面bond0對應線只有一個接了網線，所以狀態是一個up, 一個down . 

[root@wsjrac01 oracle]# more /proc/net/bonding/bond0

下面心跳線都接了網線，所以狀態都是UP
