UBuntu 14.04 LTE设置IP地址和一些服务器版本的Linux还不太一样。以Centos 7.0为例，网卡IP地址的配置文件应该是/etc/sysconfig/network-scripts/ifcfg-eth0
首先UBuntu 14.04 LTE下面IP地址的配置文件是/etc/network/interfaces。
[email protected]:/etc/network$ cat /etc/network/interfaces # interfaces(5) file used by ifup(8) and ifdown(8) auto lo iface lo inet loopback auto eth0 iface eth0 inet static address 192.168.2.100 gateway 192.168.2.2 netmask 255.255.255.0 network 192.168.2.0 broadcast 192.168.2.255 dns-nameservers 8.8.8.8 [email protected]:/etc/network$
把地址配好后用ifdown eth0后跟上ifup eth0重启网卡让前面的配置生效
[email protected]:/etc/network$ sudo ifdown eth0
[email protected]:/etc/network$ sudo ifup eth0
[email protected]:/etc/network$ ifconfig
