手机给电脑配置
手机设置
打开设置 
设置IP地址，启用共享，注意这个ip地址设置跟电脑同一个局域网。 
通过上面的步骤，手机的就启动的代理设置了代理服务为：192.168.0.29:1082。
电脑设置
以ubuntu为例，打开设置界面，打开代理。 
将代理配置为手动模式，然后将所有的服务都代理到192.168.0.29:1082上。 
上面的意思就是HTTP/HTTPS/FTP/SOCKS的服务都定向到了192.168.0.29:1082这个ip服务上，让其代理上网。需要注意的是，如果手机关了科学上网，代理服务器就会异常，也会导致ubuntu所有的HTTP/HTTPS/FTP/SOCKS等都上不了网，那么要么手机打开科学上网，要么ubuntu关了代理。
PC给开发板配置
PC上设置
开发板上测试
先测试是否能访问PC的IP
nc -zv 10.0.xx.140 7897
Connection to 10.0.xx.140 7897 port [tcp/*] succeeded!
设置代理
export http_proxy=http://10.0.91.140:7897
export https_proxy=http://10.0.91.140:7897
export all_proxy=http://10.0.91.140:7897
验证

需要注意的是开发板上如果sudo也要走代理需要加上-E，如下：
sudo -E apt update
如果要配置拉取docker也走代理
sudo mkdir -p /etc/systemd/system/docker.service.d
sudo vim /etc/systemd/system/docker.service.d/http-proxy.conf
写入一下信息
[Service]
Environment="HTTP_PROXY=http://10.0.91.140:7897"
Environment="HTTPS_PROXY=http://10.0.91.140:7897"
Environment="NO_PROXY=localhost,127.0.0.1"
然后重启docker
sudo systemctl daemon-reload
sudo systemctl restart docker
