1,备份网卡信息。

命令： cp /etc/sysconfig/network-scripts/ifcfg-eth0 /etc/sysconfig/network-scripts/ifcfg-bond0

cp /etc/sysconfig/network-scripts/ifcfg-eth0 /etc/sysconfig/network-scripts/eth0_bak

cp /etc/sysconfig/network-scripts/ifcfg-eth1 /etc/sysconfig/network-scripts/eth1_bak

2,修改网卡信息。

A．修改eth0

vi /etc/sysconfig/network-scripts/ifcfg-eth0

修改为：

DEVICE=eth0

BOOTPROTO=none

HWADDR=B8:AC:6F:83:7E:A6（mac地址根据具体情况而定）

ONBOOT=yes

MASTER=bond0

SLAVE=yes

B．修改eth1

vi /etc/sysconfig/network-scripts/ifcfg-eth1

修改为：

DEVICE=eth0

BOOTPROTO=none

HWADDR=B8:AC:6F:83:7E:A6（mac地址根据具体情况而定）

ONBOOT=yes

MASTER=bond0

SLAVE=yes

C．修改bond0

vi /etc/sysconfig/network-scripts/ifcfg-bond0

修改为：

DEVICE=bond0

BOOTPROTO=none

IPADDR=172.16.87.2（IP地址根据具体情况而定）

GATEWAY=172.16.87.224（根据具体情况而定）

NETMASK=255.255.255.0（根据具体情况而定）

ONBOOT=yes

BONDING_OPTS="mode=1 miimon=100 primary=eth2"

3，增加内核模块

vi /etc/modprobe.conf

alias bond0 bonding

options bond0 miimon=100 mode=1

4,重启network

5,检查绑定状态

cat /proc/net/bonding/bond0

6，回滚

cp /etc/sysconfig/network-scripts/ifcfg-eth0 /etc/sysconfig/network-scripts/eth0_bak2

cp /etc/sysconfig/network-scripts/ifcfg-eth1 /etc/sysconfig/network-scripts/eth1_bak2

mv /etc/sysconfig/network-scripts/eth1_bak /etc/sysconfig/network-scripts/ ifcfg-eth1

mv /etc/sysconfig/network-scripts/eth0_bak /etc/sysconfig/network-scripts/ ifcfg-eth0

mv /etc/sysconfig/network-scripts/ifcfg-bond0 /etc/sysconfig/network-scripts/bond0_bak

service network restart
