使用 putty 链接到树莓派
- 首先请安装 Putty 下载地址 https://www.chiark.greenend.org.uk/~sgtatham/putty/
2. 网线连接路由器和树莓派

3. 打开路由器页面找到树莓派的IP：
我这里路由器的IP是：192.168.1.1，所以在浏览器网址中输入：http://192.168.1.1/
image.png
找到路由器的IP地址是：192.168.1.100

4. 打开 Putty 选择SSH 输入 IP地址和端口号码
注意IP地址要换成我们上面找到的：192.168.1.100
然后输入用户名和密码

注意上图中我们可以看到有两个网卡：
eth0:192.168.0.150
wlan0:192.168.0.100
所以我们实际联网情况是这样的：

注意eth0 的IP已经更改为：10.114.204.195
8 手动临时修改IP地址.
ifconfig eth0 192.168.1.4 netmask 255.255.255.0
ifconfig eth0 down
ifconfig eth0 up
9 命令总结.
ifconfig
sudo ifconfig eth0 down
sudo ifconfig eth0 up
sudo nano /etc/dhcpcd.conf
动态IP:
iface eth0 inet dhcp
静态IP：
interface eth0
static ip_address=192.168.0.150
static routers=192.168.0.1
