网卡配置bond mode 4，前提交换机端口开启静态LACP模式

1、安装 ifenslave

ifenslave作用是网卡的负载均衡

  1. apt-get install ifenslave -y

2、编辑 /etc/network/interfaces 配置文件

  1. root@fvts-host-cn-alpha:~# cat /etc/network/interfaces
  2. # This file describes the network interfaces available on your system
  3. # and how to activate them. For more information, see interfaces(5).
  5. source /etc/network/interfaces.d/*
  7. # The loopback network interface
  8. auto lo
  9. iface lo inet loopback
  11. # The primary network interfacez
  12. auto eno1np0
  13. iface eno1np0 inet static
  14.         bond-master bond4
  16. auto eno2np1
  17. iface eno2np1 inet static
  18.         bond-master bond4
  20. auto bond4
  21. iface bond4 inet static
  22.       address 10.0.30.74/24
  23.       gateway 10.0.30.1
  24.       bond-mode 802.3ad                 #网卡模式 mode 4
  25.       bond-slaves eno1np0 eno2np1       #所绑定的网卡
  26.       bond-miimon 100                   #网卡状态监测周期100ms
  27.       bond-downdelay 200                #网卡down时间
  28.       bond-updelay  200                 #网卡up时间

3、开机自动加载bonding模块

  1. root@fvts-host-cn-alpha:~# vim /etc/modules
  2. # /etc/modules: kernel modules to load at boot time.
  3. #
  4. # This file contains the names of kernel modules that should be loaded
  5. # at boot time, one per line. Lines beginning with "#" are ignored.
  6. bonding            #添加这行

4、重启服务器

  1. reboot

验证
