Debian 16.04 配置双网卡绑定bond
Debian 16.04 bonding多网卡配置
- 安装负载均衡软件 fenslave
root@ubuntu:~# apt-get install ifenslave
root@ubuntu:~# dpkg -l | grep ifenslave
ii ifenslave 2.7ubuntu1 all configure network interfaces for parallel routing (bonding)
- 添加 bonding 模块，使之可以开机自动加载该模块
root@ubuntu:~# echo "bonding" >> /etc/modules
root@ubuntu:~# cat /etc/modules
# /etc/modules: kernel modules to load at boot time.
#
# This file contains the names of kernel modules that should be loaded
# at boot time, one per line. Lines beginning with "#" are ignored.
bonding
- 接着可以手动加载绑定内核模块，也可以重启
root@ubuntu:~# modprobe bonding
root@ubuntu:~# lsmod | grep bonding
bonding
- 编辑 /etc/network/interfaces 配置文件
- 设置主备模式 （active-backup）
root@ubuntu:~# vim /etc/network/interfaces
# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).
source /etc/network/interfaces.d/*
# The loopback network interface
auto lo
iface lo inet loopback
# The primary network interface
auto eth0 #该网卡使用来远程使用的
iface eth0 inet static
address 192.168.121.16
netmask 255.255.255.0
gateway 192.168.121.2
auto eth1 #绑定的网卡eth1
iface eth1 inet manual #最好设置为手动,设置为static可能会出问题
bond-master bond0 #绑定的接口
bond-primary eth1 #表示该网卡是主网卡，有流浪优先走该网卡
auto eth2 #绑定的网卡eth2
iface eth2 inet manual
bond-master bond0 #绑定的接口
auto bond0 #绑定网卡名
iface bond0 inet static
address 192.168.121.100
netmask 255.255.255.0
gateway 192.168.121.2
bond-slaves none #主备模式，没有从属网卡
bond-mode 1 #1代表主备模式active-backup
bond-miimon 200 #200毫秒监测一次网卡状态，如果有一条线路不通就切换另一条线路
- 设置负载均衡模式 (balace-rr)

- 重启网络服务
root@ubuntu:~# systemctl restart networking
- 查看bond
