# The loopback network interface
auto lo
iface lo inet loopback
# The primary network interface
auto eth0
iface eth0 inet static
address 192.168.1.20
netmask 255.255.255.0
gateway 192.168.1.1
dns-nameservers 192.168.1.1 #dns在这边改了，不是在/etc/resolv.conf改
改网络接口名称（原先接口名称为p2p1）
1、查mac地址
2、新建文件
nano /etc/udev/rules.d/70-persistent-net.rules
SUBSYSTEM==”net”, ACTION==”add”, ATTR{address}==”00:e0:4c:60:d1:59”, NAME=”eth0”
3、更改上面的文件
/etc/network/interfaces
