注意：請在配置前關(guān)閉NetworkManager服務(wù)
[root@h63 ~]# service NetworkManager status && service NetworkManager start
網(wǎng)卡綁定一次可以綁定多個網(wǎng)卡，你可以使用ifconfig -a查看你的網(wǎng)卡信息，例如：
[root@h63 ~]# ifconfig -a

這里有4個網(wǎng)卡，分別是em1、em2、em3和em4，我們把em1和em2做一個綁定，綁定模式為6（關(guān)于網(wǎng)卡綁定模式的介紹請看Linux網(wǎng)卡綁定探析），首先我給給網(wǎng)卡綁定后的設(shè)備起個名字bond0（名稱可以自定義），并創(chuàng)建：
[root@h63 ~]# vim /etc/sysconfig/network-scripts/ifcfg-bond0
DEVICE=bond0　　　　　　　　#設(shè)備名稱
BOOTPROTO=static　　　　　　#靜態(tài)IP
ONBOOT=yes　　　　　　　  　#自動啟動
IPADDR=172.16.16.63　　　　#設(shè)備綁定的IP
GATEWAY=172.16.23.254       #設(shè)備綁定的網(wǎng)關(guān)
NETMASK=255.255.248.0 　　 #設(shè)備綁定的掩碼
TYPE=Ethernet　　　　　　　　 #設(shè)備綁定的類型

編輯需要綁定的網(wǎng)卡：
[root@h63 ~]# vim /etc/sysconfig/network-scripts/ifcfg-em1

DEVICE=em1
BOOTPROTO=none
ONBOOT=yes
MASTER=bond0　　#綁定后的設(shè)備名稱
SLAVE=yes
TYPE=Ethernet

[root@h63 ~]# vim /etc/sysconfig/network-scripts/ifcfg-em2

DEVICE=em2
BOOTPROTO=none
ONBOOT=yes
MASTER=bond0　　#綁定后的設(shè)備名稱
SLAVE=yes
TYPE=Ethernet
說明：配置網(wǎng)卡時不要填寫IP地址和MAC地址

配置加載模式設(shè)置：
[root@h63 ~]# vim /etc/modprobe.conf

alias bond0 bonding
options bond0 miimon=100 mode=6

說明：mode是網(wǎng)卡綁定的模式，此處是模式6

也可以在/etc/modprobe.d/下創(chuàng)建一個文件：
[root@h63 ~]# vim /etc/modprobe.d/bond

alias bond0 bonding
options bond0 miimon=100 mode=6

綁定配置完成，重啟網(wǎng)絡(luò)服務(wù)
[root@h63 ~]#service network restart

查看網(wǎng)卡綁定的情況：

[root@h63 ~]# cat /proc/net/bonding/bond0

至此，網(wǎng)卡綁定就完成了。有不對的地方，還請指教。
