How to use Nginx proxy to access the Internet

http proxy configuration

# 正向代理上网
server {
  listen    38080;

  # 解析域名
  resolver   8.8.8.8;

  location / {
    proxy_pass $scheme://$http_host$request_uri;
  }
}

You need to recompile nginx here. You need to check the current nginx version and compilation options, and then go to the official website to download the same version of nginx source code and recompile

/usr/local/nginx/sbin/nginx -v

wget http://nginx.org/download/nginx-1.15.12.tar.gz
tar -zxvf nginx-1.15.12.tar.gz

Download the module ngx_http_proxy_connect_module

git clone https://github.com/chobits/ngx_http_proxy_connect_module

Patch and modify the nginx source code. This step is very important, otherwise the subsequent make will not pass.

patch -d /root/nginx-1.15.12/ -p 1 < /root/ngx_http_proxy_connect_module/patch/proxy_connect_rewrite

Add the module after the original configuration, pay attention after making Do not install

cd /root/nginx-1.15.12/
./configure --with-http_stub_status_module --with-http_ssl_module --with-file-aio --with-http_realip_module --add-module=/root/ngx_http_proxy_connect_module/
make
mv /usr/local/nginx/sbin/nginx /usr/local/nginx/sbin/nginx.bak
cp /root/nginx-1.15.12/objs/nginx /usr/local/nginx/sbin/

Change the configuration file as follows, and then start the service

# 正向代理上网
server {
  listen    38080;

  # 解析域名
  resolver   8.8.8.8;

  # ngx_http_proxy_connect_module
  proxy_connect;
  proxy_connect_allow      443 563;
