linux单网卡配置多IP

linux单网卡配置多IP

 

1、通过复制一个ifcfg-eth0:1配置文件实现：

 

cp /etc/sysconfig/network-scripts/ifcfg-eth0 /etc/sysconfig/network-scripts/ifcfg-eth0:1

  www.2cto.com  

vi /etc/sysconfig/network-scripts/ifcfg-eth0:1

 

# Intel Corporation 82566DC Gigabit Network Connection

DEVICE=eth0

BOOTPROTO=none

BROADCAST=218.95.37.255

HWADDR=00:19:d1:34:2d:b8

IPADDR=218.95.37.250

NETMASK=255.255.255.192

NETWORK=218.95.37.192

ONBOOT=yes

GATEWAY=218.95.37.193

TYPE=Ethernet

 

ifconfig eht0:1 up

 

2、临时方式(重启后就丢失了):

 

ifconfig eth0:1 192.168.0.2 netmask 255.255.255.0 up

  www.2cto.com  

3、脚本方式实现：

 

#!/bin/sh

 

eth01=/etc/sysconfig/network-scripts/ifcfg-eth0:1

 

touch $eth01

 

echo DEVICE=eth0:1>>$eth01

echo BOOTPROTO=none>>$eth01

echo IPADDR=192.168.40.76>>$eth01

echo NETMASK=255.255.255.0>>$eth01

echo ONBOOT=yes>>$eth01

 

/etc/init.d/network restart
