網卡綁定功能可以起到線路冗余的效果，是一項很實用的功能
基本配置如下
綁定後的網卡
[root@localhost ~]# cat /etc/sysconfig/network-scripts/ifcfg-bond0
DEVICE=”bond0″
NM_CONTROLLED=”yes”
ONBOOT=”yes”
IPADDR=192.168.1.2
NETMASK=255.255.255.0
GATEWAY=192.168.1.1
USERCTL=no
BONDING_OPTS=”mode=1 miimon=50″
注：mode=1為主備模式，0為負載均衡模式，交換機段需要做端口聚合
成員網卡
[root@localhost ~]# cat /etc/sysconfig/network-scripts/ifcfg-eth0
DEVICE=”eth0″
NM_CONTROLLED=”no”
ONBOOT=”yes”
#IPADDR=192.168.1.2
#NETMASK=255.255.255.0
MASTER=bond0
SLAVE=yes
USERCTL=no
成員網卡
[root@localhost ~]# cat /etc/sysconfig/network-scripts/ifcfg-eth1
DEVICE=”eth1″
NM_CONTROLLED=”no”
ONBOOT=”yes”
#IPADDR=192.168.1.2
#NETMASK=255.255.255.0
MASTER=bond0
SLAVE=yes
USERCTL=no
綁定完成後，重啟網絡服務（建議重啟系統）
service network restart
網絡重起後，bond如下所示，已成功配置
[root@localhost ~]# cat /proc/net/bonding/bond0
