家中路由添加静态IP映射（二）

家中的路由器普遍通过DHCP向连接到此路由器的客户主机提供IP配置方式，但是一般都是动态IP；

假设需要静态IP配置到个人电脑，就要在路由器上进行配置IP和MAC地址映射关系。如上篇截图。路由器端配置完，继续在本地主机配置。

我的操作系统是Ubuntu16.04，默认使用NetworkManager管理网络连接，所以首先由禁用NetworkManager

1.stop and disable NetworkManager

sudo systemctl stop NetworkManager
sudo systemctl disable NetworkManager

2.drop status of NetworkManger

sudo mv /var/lib/NetworkManager/NetworkManager.state /var/lib/NetworkManager/NetworkManager.state.bak

3.edit interfaces

sudo vim /etc/network/interfaces

# interfaces(5) file used by ifup(8) and ifdown(8)
auto lo
iface lo inet loopback

auto wlan0
iface wlan0 inet static
netmask 255.255.255.0
gateway 192.168.0.1
address 192.168.0.5
pre-up ip link set wlan0 up
pre-up iwconfig wlan0 essid ssid
wpa-ssid Tenda_68A3D8 # ssid
wpa-psk wxfzwqhqq　　# password

4. config resolve.conf and add nameserver

sudo vim /etc/resolv.conf or sudo vim /etc/resolvconf/resolv.conf.d/base

nameserver 192.168.0.1
5. restart networking

sudo /etc/init.d/networking restart
