add ngx_http_proxy_connect_module-master to nginx-1.15.2

add ngx_http_proxy_connect_module-master to nginx-1.15.2

前言

原生nginx只支持http正向代理.
为了nginx支持https正向代理,可以打ngx_http_proxy_connect_module-master补丁+ ssl模块支持.

实验

实验环境

win10真机 + debian8.8虚拟机

配置网络

root@localhost:~# cat /etc/network/interfaces
auto eth0
allow-hotplug eth0
iface eth0 inet static
address 192.168.11.200
netmask 255.255.255.0
gateway 192.168.11.2

下载nginx源码

ngx_http_proxy_connect_module-master补丁支持的最新的nginx版本为nginx-1.15.2

wget http://nginx.org/download/nginx-1.15.2.tar.gz
tar -xzvf ./nginx-1.15.2.tar.gz

下载ngx_http_proxy_connect_module

https://github.com/chobits/ngx_http_proxy_connect_module
将下载好的ngx_http_proxy_connect_module-master.zip上传到 /home/test_nginx/

aptitude install unzip
unzip ./ngx_http_proxy_connect_module-master.zip

配置nginx

cd /home/test_nginx/nginx-1.15.2
./configure --help | grep ssl
aptitude update
aptitude search PCRE
aptitude install libpcre3 libpcre3-dev
aptitude search ssl
aptitude install libssl-dev
./configure --add-module=/home/test_nginx/ngx_http_proxy_connect_module-master --with-http_ssl_module

对nginx打ngx_http_proxy_connect_module-master补丁

注意 nginx-1.15.2对应的补丁为proxy_connect_rewrite_1015.patch,可以先看ngx_http_proxy_connect_module-master的readme

patch -d /home/test_nginx/nginx-1.15.2/ -p 1 < /home/test_nginx/ngx_http_proxy_connect_module-master/patch/proxy_connect_rewrite_1015.patch
  • 1

运行补丁的结果

补丁的结果很干净。
如果补丁不对,会由错误提示信息.

patching file src/http/ngx_http_core_module.c
patching file src/http/ngx_http_parse.c
patching file src/http/ngx_http_request.c
patching file src/http/ngx_http_request.h

nginx的命令行用法

root@localhost:/home/test_nginx/nginx-1.15.2# /usr/local/nginx/sbin/nginx -h
nginx version: nginx/1.15.2
Usage: nginx [-?hvVtTq] [-s signal] [-c filename] [-p prefix] [-g directives]

Options:
  -?,-h         : this help
  -v            : show version and exit
  -V            : show version and configure options then exit
  -t            : test configuration and exit
  -T            : test configuration, dump it and exit
  -q            : suppress non-error messages during configuration testing
  -s signal     : send signal to a master process: stop, quit, reopen, reload
  -p prefix     : set prefix path (default: /usr/local/nginx/)
  -c filename   : set configuration file (default: conf/nginx.conf)

修改打完补丁的nginx-1.15.2的配置文件-支持https正向代理

这个配置文件就用ngx_http_proxy_connect_module-master自带的配置文件

/usr/local/nginx/sbin/nginx -s stop
cat /usr/local/nginx/conf/nginx.conf
