Nginx Xml Distributing Upstream Module

This Nginx upstream module based on post content. Designed for wechat.

This module is open sourced under the same license as Nginx.

You could read doc/doc.txt and following installation guide.

You should also be familiar with wechat development. If not, you could learn it at mp.weixin.qq.com.

Installation

Installation Instruction: (Tested in ubuntu 14.04)

• First, you must have libxml, pcre and zlib installed. If not, you need:
  sudo apt-get install libxml2-dev libpcre3-dev zlib1g-dev
• Add a soft link: sudo ln -s libxml2/libxml /usr/include/libxml

And you need to use 1.6.x nginx with this module. Other nginx may not work. You can get nginx by:
wget http://nginx.org/download/nginx-1.6.3.tar.gz &&tar xzf nginx-1.6.3.tar.gz

Says the nginx source folder is ./nginx-1.6.3, then you should modify nginx:

• First go to nginx-1.6.3 folder.
• cp -af ../src/ngx_http_upstream.h src/http/
• sed -i 's/.*-Werror.*//g' auto/cc/gcc. If not, after ./configure,
  you can also go to nginx-1.6.3/objs/Makefile, delete -Werror in line 2.

Compile:

• First go to nginx-1.6.3 folder.
• Execute ./configure --add-module=../src --prefix=/usr/local/nginxXml
• Then, Return to nginx-1.6.3 folder, make && sudo make install.
• You could find nginx in /usr/local/nginxXml

We give doc/nginx.conf as an example. The ticketups in upstream test block is what you need to write. You could use regular expression in xml body to match each server.

You could use re in Content, MsgType, CreateTime, FromUserName and so on. If the message couldn't be matched by any server, it's sent to the last server.

Thanks

Thanks for Evan Miller's tutorial and upstream hash module. Many of my source code comes from that module.

Thanks for developer of libxml and pcre.

Thanks for Liuqiang teacher, Chen Huarong, Jiang Linnan, Gong Dahan, Yu Zeming and all of my other classmates.

Thanks for open source!
