应用正向代理的场景,以及正向代理和反向代理的区别:

了解:
客户端 代理 服务器
A B C
正向： * B C
反向： A B *

正向暗藏客户端
反向暗藏服务端

1 查看文档

 https://github.com/chobits/ngx_http_proxy_connect_module/blob/master/README.md

2 其中: 构建为动静模块

装置nginx 和 nginx_proxy_connect module

从nginx的1.9.11开始，你也能够作为一个动静模块，通过应用编译该模块--add-dynamic-module=PATH选项，而不是--add-module=PATH在对./configure命令行。
$ $ wget http://nginx.org/download/ngi...
$ tar -xzvf nginx-1.9.12.tar.gz
$ cd nginx-1.9.12/
$ patch -p1 < /path/to/ngx_http_proxy_connect_module/patch/proxy_connect.patch
$ ./configure --add-dynamic-module=/path/to/ngx_http_proxy_connect_module
$ make && make install

3 make可能遇到的问题

1 error: this statement may fall through [-Werror=implicit-fallthrough=]
2 “src/os/unix/ngx_user.c:26:7: error: ‘struct crypt_data’ has no member named ‘current_salt’”

问题1解决,正文掉这一行

vim /opt/nginx/nginx-1.9.2/src/os/unix/ngx_user.c
36 : / cd.current_salt[0] = ~salt[0];/

问题2解决,编译加上参数 :
make CFLAGS='-Wno-implicit-fallthrough';
make install;

4 实现后 配置 conf :

vim /usr/local/nginx/conf/nginx.conf

#user  nobody;worker_processes  1;#error_log  logs/error.log;#error_log  logs/error.log  notice;#error_log  logs/error.log  info;#pid        logs/nginx.pid;events {    worker_connections  1024;}  http {    include       mime.types;    default_type  application/octet-stream;    #access_log  logs/access.log  main;    sendfile        on;    #tcp_nopush     on;    keepalive_timeout  65;    #gzip  on; server {        listen 88;                #监听端口        resolver 183.60.82.98;   #dns解析地址        server_name  _;        #charset koi8-r;        #access_log  logs/host.access.log  main;        location / {             proxy_pass https://$host$request_uri;     #设定http代理服务器的协定和地址             proxy_set_header HOST $host;             proxy_buffers 256 4k;             proxy_max_temp_file_size 0k;             proxy_connect_timeout 30;             proxy_send_timeout 60;             proxy_read_timeout 60;             proxy_next_upstream error timeout invalid_header http_502;            #root   html;            #index  index.html index.htm;        }        error_page   500 502 503 504  /50x.html;        location = /50x.html {            root   html;        }     }   server {       resolver 8.8.8.8;   #dns解析地址       listen 89;          #代理监听端口       proxy_connect;       proxy_connect_allow            443 563;       location / {             proxy_pass $scheme://$host$request_uri;     #设定https代理服务器的协定和地址             proxy_set_header HOST $host;             proxy_buffers 256 4k;             proxy_max_temp_file_size 0k;             proxy_connect_timeout 30;             proxy_send_timeout 60;             proxy_read_timeout 60;             proxy_next_upstream error timeout invalid_header http_502;        }        error_page   500 502 503 504  /50x.html;        location = /50x.html {            root   html;        }     }   }　

启动 nginx

curl -i --proxy 192.168.3.17:89 www.baidu.com
