ubuntu 16.04 配置双网卡双IP

1、在腾讯云控制台进行弹性网卡的绑定：

2、登录到服务器上进行网卡配置：vim /etc/network/interfaces.d/50-cloud-init.cfg

auto eth0:0 iface eth0:0 inet static address 10.0.64.13 netmask 255.255.255.0 gateway 10.0.64.1

auto eth0:1 iface eth0:1 inet static address 10.0.64.16 netmask 255.255.255.0 gateway 10.0.64.1

auto eth1:0 iface eth1:0 inet static address 10.0.64.8 netmask 255.255.255.0 gateway 10.0.64.1

auto eth1:1 iface eth1:1 inet static address 10.0.64.2 netmask 255.255.255.0 gateway 10.0.64.1

3、创建路由表：vim  /etc/iproute2/rt_tables，在后面追加：

10 t1

20 t2

30 t3

40 t4

4、给4张路由表添加默认路由：

ip rule add from 10.0.64.13/32 table 10

ip rule add from 10.0.64.16/32 table 20

ip rule add from 10.0.64.8/32 table 30

ip rule add from 10.0.64.2/32 table 40

5、为防止重启后失效，将路由和策略都加入到rc.local文件，vim /etc/rc.local

6、测试
