在windows下給一塊網(wǎng)卡設置多個IP,，是比較容易的,，今天我寫的內(nèi)容是關于在LINUX系統(tǒng)下，給一塊網(wǎng)卡設置多個IP地址,，在Linux系統(tǒng)下面,，第一塊網(wǎng)卡就叫eth0，第二塊網(wǎng)卡就叫eth1,，這里我們給第一塊網(wǎng)卡設置多個IP,在Linux下,，配置網(wǎng)卡的配置文件在目錄/etc/sysconfig/network-script/下 ，原來網(wǎng)卡的配置文件名為ifcfg-eth0 ,，我們給一塊網(wǎng)卡配置多個IP地址的配置文件命名為ifcfg-eth0:1和ifcfg-eth0 :2，下面看操作如下：
