eth2

bonding模块工作方式

bonding有0-6七种模式,常用的工作方式为0、1、6三种:

0: (balance-rr) Round-robin policy: (平衡抡循环策略):传输数据包顺序是依次传输,直到最后一个传输完毕,
此模式提供负载平衡和容错能力。
1: (active-backup) Active-backup policy:(主-备份策略):只有一个设备处于活动状态。 一个宕掉另一个马上由
备份转换为主设备。mac地址是外部可见得。
此模式提供了容错能力。
2: (balance-xor) XOR policy:(广播策略):将所有数据包传输给所有接口。
此模式提供了容错能力。
3: (balance-xor) XOR policy:(平衡策略): 传输根据原地址布尔值选择传输设备。
此模式提供负载平衡和容错能力。
4: (802.3ad) IEEE 802.3ad Dynamic link aggregation.IEEE 802.3ad 动态链接聚合:创建共享相同的速度和
双工设置的聚合组。
5: (balance-tlb) Adaptive transmit load balancing(适配器传输负载均衡):没有特殊策略,第一个设备传不通就用
另一个设备接管第一个设备正在处理的mac地址,帮助上一个传。
6: (balance-alb) Adaptive load balancing:(适配器传输负载均衡):大致意思是包括mode5,bonding驱动程序
截获 ARP 在本地系统发送出的请求,用其中之一的硬件地址覆盖从属设备的原地址。就像是在服务器上不同的人
使用不同的硬件地址一样

本次参考主库,采用 模式1

安装ifenslave,用作bonding

# apt-get install ifenslave 

让系统开机自动加载模块bonding

# echo "bonding" >> /etc/modules

没有重启需要手动添加进linux 内核

# modprobe bonding 

创建vip bond

# cd /etc/network/interfaces.d# vi bond0:1# This file describes the network interfaces available on your system# and how to activate them. For more information, see interfaces(5).# The bond0:1 network interfaceauto bond0:1 iface bond0:1 inet static    address 192.168.56.99    netmask 255.255.255.0    network 192.168.56.0    gateway 192.168.56.1

添加如下网卡配置文件

# vi /etc/network/interfaces# The primary network interfaceauto bond0iface bond0 inet static        address 192.168.56.100        netmask 255.255.255.0        gateway 192.168.56.1 bond-mode 1 bond-primary eth0 bond-slaves eth0 eth1 bond-miimon 100 bond-downdelay 400 bond-updelay 800#post-up ifenslave bond0 eth0 eth1#pre-down ifenslave -d bond0 eth0 eth1

重新启动网卡

# /etc/init.d/networking restart
