在Debian系统下添加新IP,你只需要修改下 /etc/network/interfaces 文件就可以了,即在eth0接口上绑定更多的IP地址。
我们首先要编辑网卡添加新IP地址的配置文件,命令如下:
sudo vi /etc/network/interfaces
如果安装了nano更方便一些使用:
nano /etc/network/interfaces
输入以上命令之后,我们就进入了编辑器修改配置文件的界面。
举例:
单网卡“eth0”添加“192.168.1.2”和“192.168.1.3”这2个IP为例进行演示,命令代码如下:
注意,这里很重要,几个ip就加上几个:
auto eth0
auto eth0:0
auto eth0:1
默认网卡eth0的IP地址
iface eth0 inet static
address 192.168.1.1 #主机IP地址
netmask 255.255.255.0 #子网掩码
gateway 192.168.1.254 #网关地址
为网卡eth0的增加第1个IP地址
iface eth0:0 inet static
address 192.168.1.2
netmask 255.255.255.0
gateway 192.168.1.254
为网卡eth0的增加第2个IP地址
iface eth0:1 inet static
address 192.168.1.3
netmask 255.255.255.0
gateway 192.168.1.254
当以上内容编辑完成后,执行如下命令生效:
sudo /etc/init.d/networking restart
如果以上命令执行失败,重启服务器即可。
参考样板:
打开文件编辑
nano /etc/network/interfaces
编辑内容
# 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
auto eno1
auto eno1:1
auto eno1:2
auto eno1:3
auto eno1:4
iface lo inet loopback
# The primary network interface
allow-hotplug eno1
iface eno1 inet static
address 1.209.190.202/29
gateway 1.209.190.201
iface eno1:1 inet static
address 1.209.190.203/29
gateway 1.209.190.201
iface eno1:2 inet static
address 1.209.190.204/29
gateway 1.209.190.201
iface eno1:3 inet static
address 1.209.190.205/29
gateway 1.209.190.201
iface eno1:4 inet static
address 1.209.190.206/29
gateway 1.209.190.201
