在/etc/sysconfig/network-scripts/下创建ifcfg-eth0:x网卡配置文件，通过此配置文件来绑定IP,最多可绑定255个IP。
[root@info ~]# cd /etc/sysconfig/network-scripts/
[root@info network-scripts]# pwd
/etc/sysconfig/network-scripts
[root@info network-scripts]# cp ifcfg-eth0 ifcfg-eth0:1
[root@info network-scripts]# vi ifcfg-eth0:1
DEVICE=eth0:1 #设备名称
ONBOOT=yes
BOOTPROTO=static
IPADDR=172.16.0.100 #绑定IP地址
NETMASK=255.255.0.0
GATEWAY=172.16.1.1
重启网路服务
[root@info network-scripts]# service network restart
正在关闭接口 eth0： [ 确定 ]

弹出界面 eth0.tmp： [ 确定 ]
[root@info network-scripts]# ifconfig

方法二
使用ifconfig 设备名 IP地址 广播地址 子网掩码来绑定IP，缺陷是当系统重启时,ifconfig绑定的参数会丢失，需手工重新配置。但可以把配置参数加入启动文件中，让其自动运行。
[root@info network-scripts]# ifconfig eth0:2 10.0.0.100 netmask 255.0.0.0
[root@info network-scripts]# vi /etc/rc.d/rc.local
#!/bin/sh
#
# This script will be executed *after* all the other init scripts.
# You can put your own initialization stuff in here if you dont
# want to do the full Sys V style init stuff.
touch /var/lock/subsys/local
ifconfig eth0:2 10.0.0.100 netmask 255.0.0.0
[root@info ~]# ifconfig eth0:2
eth0:2 Link encap:Ethernet HWaddr 00:0C:29:84:F8:33
inet addr:10.0.0.100 Bcast:10.255.255.255 Mask:255.0.0.0
