背景需求，国内云服务器，虚拟机能够更方便得连接学术网站，例如GitHub，docker等
方案1 配置proxychains
优点，简单，傻瓜式，在需要代理的命令前加上proxychains即可
方案2 配置透明代理
为了简化流程，我写了个服务单元，并把脚本上传到对象存储，这样就能保证被墙，用户也不需要麻烦去配置
命令行一键配置
bash <(wget -qO- -o- https://e.oss-cn-beijing.aliyuncs.com/SSR/ssr-systemd.sh)
缺点：启动和关闭都需要执行source ~/.bashrc

求助各位前辈，目前这种方法无法清除当前连接终端的shell变量
需要手动执行
unset https_proxy
unset http_proxy
unset all_proxy
才能清除变量，求助优化脚本，能让用户更傻瓜式操作 |
