Linux基础入门之网络属性配置之单接口配置多IP+TUI界面配置IP

摘要

但网卡配置单IP的情况在实际应用中有时候是无法满足我们的需求的，譬如我们有多个业务跑在一台服务器上，我们不想多业务用同一个IP地址且出于成本考虑我们也不想额外再加硬件设备网卡了，那么这时候我们就需要配置单网卡多IP的配置了。本篇博文将介绍如何在RedHat系系统上配置但网卡多IP

单网卡配置多IP也是分两种的一种是静态配置一种是动态配置，还是像上篇博文所说的一样，静态配置是需要写到配置文件里面且是永久生效的，而动态配置是通过命令来实现的，这是及时生效但是不能永久有效的。

动态方式配置但网卡多IP

ifconfig IFNAME:# IPADDRES netmask MASK

例子：

上面这种添加多IP的在某些环境下还是比较麻烦的譬如说我需要添加13个IP那么就要创建eth0:0 eth0:1......eth0:12这么多文件了，是不是也很烦躁？其实我们还可以用另外一种方式添加

使用TUI界面配置IP就简单多了，下面说说怎么用TUI界面来配置IP地址

直接运行命令system-config-network-tui命令就可以了
