进入配置文件，配置IP
leafpad /etc/network/interfaces.conf
写入如下格式的内容：
/etc/network/interfaces # This file describes the network interfaces available on your system # and how to activate them. For more information, see interfaces(5). # The loopback network interface auto lo iface lo inet loopback # The primary network interface allow-hotplug eth0 iface eth0 inet dhcp # This is an autoconfigured IPv6 interface iface eth0 inet6 auto 修改为： # This file describes the network interfaces available on your system # and how to activate them. For more information, see interfaces(5). # The loopback network interface auto lo iface lo inet loopback # The primary network interface allow-hotplug eth0 auto eth0 //增加了该选项，因为使用networking restart时系统启动 auto的网卡，如不加上则启动无反应 iface eth0 inet static //配置了static 为静态ip address 192.168.1.4 //设置ip地址 netmask 255.255.255.0 //设置掩码 gateway 192.168.1.1 //设置网关 # This is an autoconfigured IPv6 interface iface eth0 inet6 auto
配置DNS（注：先删除一个之后再新建一个resolv.conf，可防止重启后resolv.conf内容被清空）
leafpad /etc/resolv.conf
/etc/resolv.conf nameserver 202.106.0.20 nameserver 202.106.46.151 修改为： nameserver 202.106.0.20 nameserver 202.106.46.151 nameserver 8.8.8.8
