RHEL5下一个网卡绑定多个IP

在Windows下，一个网卡可以绑定多个IP地址，只要在网卡的“TCP/IP属性”的“高级”选项中添加具体的IP地址就可以实现了，那么在Linux字符环境下又是如何实现的呢！下面就来介绍下操作步骤：

[root@ns1 ~]# cd /etc/sysconfig/network-scripts/

[root@ns1 network-scripts]# ls
ifcfg-eth0    ifdown-isdn    ifup-aliases ifup-plip    ifup-wireless
ifcfg-lo      ifdown-post    ifup-bnep     ifup-plusb   init.ipv6-global
ifdown        ifdown-ppp     ifup-eth      ifup-post    net.hotplug
ifdown-bnep   ifdown-routes ifup-ippp     ifup-ppp     network-functions
ifdown-eth    ifdown-sit     ifup-ipsec    ifup-routes network-functions-ipv6
ifdown-ippp   ifdown-sl      ifup-ipv6     ifup-sit
ifdown-ipsec ifdown-tunnel ifup-ipx      ifup-sl
ifdown-ipv6   ifup           ifup-isdn     ifup-tunnel

[root@ns1 network-scripts]# cp ifcfg-eth0 ifcfg-eth0:1

[root@ns1 network-scripts]# vi ifcfg-eth0:1
