本文主要是介绍bond聚合和team聚合，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！
链路聚合
网卡的链路聚合就是将多块网卡连接起来，当一块网卡损坏，网络依旧可以正常运行，可以有效的防止因为网卡损坏带来的损失，同时也可以提高网络访问速度。
网卡的链路聚合方式：
bond：最多可以添加两块网卡
team：最多可以添加八块网卡
bond的常用的2种模式：
bond0(balance-rr)
bond0用于负载轮询（2个网单独都是100MB，聚合为1个网络传输带宽为200MB）
bond1(active-backup)
bond1用于高可用，其中一条线若断线，其他线路将会自动备援
--> eth0 ----\app --发送数据到--> bond0 <---> switch --> eth1 ----/
