实现方法
原理大概是 nginx 的 stream 模块 tcp 直接转发 https. 服务器使用 ubuntu 20.04.1
编译安装nginx
sudo apt update
sudo apt install -y build-essential libtool zlib1g-dev openssl libpcre3 libpcre3-dev libssl-dev libgeoip-dev
wget https://nginx.org/download/nginx-1.19.4.tar.gz 
tar -zvxf nginx-1.19.4.tar.gz 
rm nginx-1.19.4.tar.gz
cd nginx-1.19.4
./configure --prefix=/usr --sbin-path=/usr/sbin/nginx --conf-path=/etc/nginx/nginx.conf --error-log-path=/var/log/nginx/error.log --http-log-path=/var/log/nginx/access.log --pid-path=/var/run/nginx/nginx.pid --lock-path=/var/lock/nginx.lock --with-http_ssl_module --with-stream_ssl_preread_module  --with-stream --with-stream_geoip_module
sudo make && sudo make install
sudo mkdir /usr/logs
创建 /usr/lib/systemd/system/nginx.service
[Unit]
Description=nginx
After=network.target
  
[Service]
Type=forking
ExecStart=/usr/sbin/nginx
ExecReload=/usr/sbin/nginx -s reload
ExecStop=/usr/sbin/nginx -s quit
PrivateTmp=true
  
[Install]
WantedBy=multi-user.target
修改 /etc/nginx/nginx.conf

    proxy_download_rate $downspeed;  
		proxy_upload_rate $upspeed;
				#屏蔽中国大陆以外的连接
		include geocn.conf;  
  }
}
启动nginx并设置开机自启
service nginx start
systemctl enable nginx.service
开启bbr加速,开端口443
