Linux下一块网卡设置多个IP地址

[日期:2018-05-25] 来源:  作者: [字体: ]

在windows下给一块网卡设置多个IP,是比较容易的,今天我写的内容是关于在LINUX系统下,给一块网卡设置多个IP地址,在Linux系统下面,第一块网卡就叫eth0,第二块网卡就叫eth1,这里我们给第一块网卡设置多个IP,在Linux下,配置网卡的配置文件在目录/etc/sysconfig/network-script/下 ,原来网卡的配置文件名为ifcfg-eth0 ,我们给一块网卡配置多个IP地址的配置文件命名为ifcfg-eth0:1和ifcfg-eth0:2,下面看操作如下:
