Tinyproxy 是一个轻量级的开源 web 代理守护进程，其设计目标是快而小。它适用于需要完整 HTTP 代理特性，但系统资源又不足以运行大型代理的场景，比如嵌入式部署。

Tinyproxy 对小规模网络非常有用，这样的场合下大型代理会使系统资源紧张，或有安全风险。Tinyproxy 的一个关键特性是其缓冲连接的理念。从效果上看， Tinyproxy 对服务器的响应进行了高速缓冲，然后按照客户端能够处理的最高速度进行响应。该特性极大的降低了网络延滞带来的问题.

在云服务器上安装 TinyProxy

我的是腾讯云的ubuntu主机

sudo apt  install tinyproxy

配置 TinyProxy

vim /etc/tinyproxy/tinyproxy.conf

修改port

改 Port 端口，默认为 8888

注释掉 Allow，表示允许所有人访问代理

#Allow 127.0.0.1

启动tinyproxy

systemctl start tinyproxy.service 
systemctl restart tinyproxy.service 
systemctl stop tinyproxy.service 
systemctl status tinyproxy.service 
systemctl enable tinyproxy.service 

配置防火墙

firewall-cmd --add-port=8888/tcp  --permanent
firewall-cmd  --reload

查看log

sudo tail -f /var/log/tinyproxy/tinyproxy.log

显示

在客户端设置代理

echo export HTTP_PROXY=http://cloudvirtualmachineIP:8888 >> ~/.bashrc
source  ~/.bashrc

验证是否代理成功

在python解释器中

import requests
requests.get('http://httpbin.org/ip').json()  

得到你云主机的ip地址就是设置成功了
