Linux ->> UBuntu 14.04 LTE下设置静态IP地址
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。
jerry@ubuntu:/etc/network$ cat /etc/network/interfaces
# interfaces() file used by ifup() and ifdown()
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
jerry@ubuntu:/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
jerry@ubuntu:/etc/network$ sudo ifdown eth0
jerry@ubuntu:/etc/network$ sudo ifup eth0
jerry@ubuntu:/etc/network$ ifconfig

有时你在一台刚刚安装好的Ubuntu机器上运行ifdown eth0命令可能会出现ifdown: interface eth0 not configured这样的错误提示，原因是ifdown和ifup是依据/run/network/ifstate里的内容来知道有哪些网络接口。cat一下有没有eth0，没有就添加eth0=eth0到文件的尾端。然后再运行下命令就解决了。
