删除用户默认配置文件
由于在默认清空下，配置文件是系统自动生成的用户设备配置文件保存在/etc/udev/rule.d/下面：
# cp /etc/udev/rule.d /etc/udev/rule.d.bak.0 -R
# rm /etc/udev/rule.d/*
修改网卡配置文件，添加多IP配置
#vim /etc/network/interfaces
修改或添加如下内容：
auto lo
iface lo inet loopback
auto eth0
iface eth0 inet static
address 192.168.76.192
netmask 255.255.255.0
gateway 192.168.76.254
auto eth0:0
iface eth0:0 inet static
address 192.168.76.193
netmask 255.255.255.0
gateway 192.168.76.254
auto eth0:1
iface eth0:1 inet static
address 192.168.76.194
netmask 255.255.255.0
gateway 192.168.76.254
实验环境，我添加了三个IP地址
让配置生效
#/etc/init.d/networking restart
检查效果
#ifconfig

可以看到三个IP地址，就说明配置成功了。
