Debian系统添加绑定多个IP地址

Debian需要修改 /etc/network/interfaces 文件来修改或添加多个IP地址的绑定

先备份interfaces文件

cp /etc/network/interfaces /root/interfaces.bak

使用VIM编辑配置文件

vim /etc/network/interfaces

示例文件：

# 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 eno1:0
iface eno1:0 inet static
    address 12.3.12.10
    netmask 255.255.255.192
    gateway 12.3.12.1
    dns-nameservers 8.8.8.8
	
auto eno1:1
iface eno1:1 inet static
    address 12.3.12.11
    netmask 255.255.255.192
    gateway 12.3.12.1
    dns-nameservers 8.8.8.8
 
auto eno1:2
iface eno1:2 inet static
    address 12.3.12.12
    netmask 255.255.255.192
    gateway 12.3.12.1
    dns-nameservers 8.8.8.8
 
auto eno1:3
iface eno1:3 inet static
    address 12.3.12.13
    netmask 255.255.255.192
    gateway 12.3.12.1
    dns-nameservers 8.8.8.8

重启网络

service networking restart

可用以下脚本批量添加，注意根据实际ip地址进行改动

# !/bin/bash
for ((i=1;i<=64;i=i+1))
do
echo "auto eth0:$i">>/etc/network/interfaces
echo "iface eth0:$i inet static">>/etc/network/interfaces
let j=$i+29
echo "address 1.2.3.$j">>/etc/network/interfaces
echo "netmask 255.255.255.248">>/etc/network/interfaces
echo "gateway 1.2.3.4">>/etc/network/interfaces
echo " ">>/etc/network/interfaces
done
# end

同样适用于ubuntu 17.10以前的版本，ubuntu17.10以后的请看这里
