通过单个配置文件实现腾讯云双网卡配置多ip

之前都是用子配置文件方式,比如 ifcfg-eth0:0 ifcfg-eth0:1这种,需要创建多个配置文件。
现在通过单个配置文件实现多ip配置。

# 第一块网卡

[root@VM-0-3-centos network-scripts]# cat ifcfg-eth0
BOOTPROTO=static
DEVICE=eth0
HWADDR=52:54:00:4f:c4:e4
ONBOOT=yes
PERSISTENT_DHCLIENT=yes
TYPE=Ethernet
USERCTL=no
IPADDR=172.17.0.3
NETMASK=255.255.240.0
GATEWAY=172.17.0.1

IPADDR1=172.17.0.13
NETMASK1=255.255.240.0

IPADDR2=172.17.0.14
NETMASK2=255.255.240.0

IPADDR3=172.17.0.15
NETMASK3=255.255.240.0

IPADDR4=172.17.0.2
NETMASK4=255.255.240.0

IPADDR5=172.17.0.8
NETMASK5=255.255.240.0

# 第二块网卡配置

[root@VM-0-3-centos network-scripts]# cat ifcfg-eth1
BOOTPROTO=static
DEVICE=eth1
ONBOOT=yes
PERSISTENT_DHCLIENT=yes
TYPE=Ethernet
USERCTL=no
IPADDR=172.17.0.6
NETMASK=255.255.240.0

IPADDR1=172.17.0.11
NETMASK1=255.255.240.0

IPADDR2=172.17.0.12
NETMASK2=255.255.240.0

IPADDR3=172.17.0.16
NETMASK3=255.255.240.0

IPADDR4=172.17.0.4
NETMASK4=255.255.240.0

IPADDR5=172.17.0.5
NETMASK5=255.255.240.0

# 配置策略路由

echo "10 t1" >> /etc/iproute2/rt_tables
echo "20 t2" >> /etc/iproute2/rt_tables

# 测试ip连通性

#!/bin/bash

while read line || [[ -n ${line} ]]

        echo "ip地址 " $line
