1.)#vi/etc/modprobe.conf

后添加

aliasbond0bonding

optionsbondingmax_bonds=1

2.)#viifcfg-bond0
加入如下内容
#IntelCorporation82545EMGigabitEthernetController(Copper)
DEVICE=bond0
BOOTPROTO=none
BROADCAST=192.168.100.255
IPADDR=192.168.100.12
NETMASK=255.255.255.0
NETWORK=192.168.100.0
ONBOOT=yes

BONDING_OPTS="mode=1miimon=100primary=eth0"

3.)修改ifcfg-eth0ifcfg-eth1
#viifcfg-eth0
修改为如下内容
#IntelCorporation82545EMGigabitEthernetController(Copper)
DEVICE=eth0
BOOTPROTO=none
ONBOOT=yes
MASTER=bond0
SLAVE=yes
#cpifcfg-eth0ifcfg-eth1
#viifcfg-eth1
修改为如下内容
#IntelCorporation82545EMGigabitEthernetController(Copper)
DEVICE=eth0
BOOTPROTO=none
ONBOOT=yes
MASTER=bond0
SLAVE=yes

4.)重启服务
#servicenetworkrestart
查看一下

[root@localhost~]#ifconfig-a

或者

1.新建ifcfg-bond0

[root@dexnetwork-scripts]#cd/etc/sysconfig/network-scripts/ [root@dexnetwork-scripts]#cpifcfg-eth0ifcfg-bond0 [root@dexnetwork-scripts]#viifcfg-bond0 加入如下内容 #IntelCorporation82545EMGigabitEthernetController(Copper) DEVICE=bond0 BOOTPROTO=none BROADCAST=192.168.100.255 IPADDR=192.168.100.12 NETMASK=255.255.255.0 NETWORK=192.168.100.0 ONBOOT=yes 2.修改ifcfg-eth0ifcfg-eth1 [root@dexnetwork-scripts]#viifcfg-eth0 修改为如下内容 #IntelCorporation82545EMGigabitEthernetController(Copper) DEVICE=eth0 BOOTPROTO=none ONBOOT=yes MASTER=bond0 SLAVE=yes [root@dexnetwork-scripts]#cpifcfg-eth0ifcfg-eth1 [root@dexnetwork-scripts]#viifcfg-eth1 修改为如下内容 #IntelCorporation82545EMGigabitEthernetController(Copper) DEVICE=eth0 BOOTPROTO=none ONBOOT=yes MASTER=bond0 SLAVE=yes 3.修改/etc/modprobe.conf文件 [root@dexnetwork-scripts]#vi/etc/modprobe.conf 加入如下两行 aliasbond0bonding optionsbond0miimon=100mode=1 mode=0表示两块网卡同时工作，提供负载均衡 mode=1表示提供冗余功能（主备模式）
