Nginx正向代理配置

Nginx 正向代理默认只支持 http 协议，不支持 https 协议，需借助 "ngx_http_proxy_connect_module" 模块实现 https 正向代理，详情请参考：

https://github.com/chobits/ngx_http_proxy_connect_module

安装Nginx某些模块会用到的系统类库

yum install -y dnf install libxml2 libxml2-devel libxslt-devel gcc gcc-c++ make pcre pcre-devel zlib zlib-devel openssl openssl-devel patch perl-ExtUtils-Embed gd-devel geoip-devel gperftools gperftools-devel

一、下载 nginx

mkdir -p /opt/nginx && cd /opt/nginx
wget http://nginx.org/download/nginx-1.22.1.tar.gz
tar -xzvf nginx-1.22.1.tar.gz

二、下载 ngx_http_proxy_connect_module 模块

mkdir -p /opt/packages && cd /opt/packages
unzip ngx_http_proxy_connect_module-master.zip
mv ngx_http_proxy_connect_module-master /opt/packages/ngx_http_proxy_connect_module

三、编译安装 nginx

cd /opt/nginx/nginx-1.22.1/
patch -p1 < /opt/packages/ngx_http_proxy_connect_module/patch/proxy_connect_rewrite_102101.patch
./configure --add-module=/opt/packages/ngx_http_proxy_connect_module ...
make && make install

四、配置 nginx
vim conf/nginx.conf

    server {
        listen 8888;
        resolver 8.8.8.8 ipv6=off;
        proxy_connect;
        proxy_connect_allow 443 80;
        location / {
            proxy_pass $scheme://$http_host$request_uri;
            proxy_set_header Host $http_host;
            proxy_set_header X-Real-IP $remote_addr;
            proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
            proxy_set_header X-Forwarded-Proto $scheme;
            proxy_connect_timeout 10;
            proxy_send_timeout 600;
            proxy_read_timeout 600;

        }
    }

 五、重启 nginx。

注：`/sbin/nginx -s reload` 新增模块时重启有时不生效。

cd /opt/nginx/
./sbin/nginx -s stop
./sbin/nginx
