在网卡上绑定多个ip

如果要在eth0网卡设备上添加两个lP别名192.168.8.43和192.168.8.44，可以通过以下的ifconfig和route命令来进行：

[root@ShadowFiend Gogo_yueyue]# ifconfig eth0:2 172.29.0.76 broadcast 172.29.255.255 netmask 255.255.0.0 up 
[root@ShadowFiend Gogo_yueyue]# route add -host 172.29.0.76 dev eth0:2

检验

[Gogo_yueyue@ShadowFiend ~]$ ifconfig
