解决公司jboss集群的问题，开始学习apache模块开发，开发的平台采用windows平台，是希望大家更加容易能够进入开发阶段，公司大部分都有vs2008.
1.安装apache 安装包 httpd-2.2.21-win32-x86-no_ssl.msi
一定要custom全部安装，否则就不会有include和lib目录
2.配置apxs
1)安装apxs 安装包apxs_win32
2)安装Strawberry Perl 安装包strawberry-perl-5.16.3.1-32bit.msi
3)进入dos命令提示符，转到apxs安装目录下，输入perl Configure.pl，按要求填写apache的安装目录...\apache2.2和命令名称“httpd.exe”
4)通过上一步，就会在apache2.2\bin下生成apxs命令，并且在apache2.2目录下生成了build目录
5)修改在apache2.2下build目录中的config_vars.mk文件
将CC = gcc 的gcc改为cl.exe ，LD = g++的g++改为link.exe，CPP = gcc-E的gcc-E删掉
6)设置apache下的bin的命令apxs的路径为环境变量，以放便在不进入具体安装目录下运行apxs
3.编译apache模块
1)运行Visual Studio 2008 命令提示(在开始的Microsoft Visual Studio 2008下可以找到)
2)运行apxs -g -n helloworld(helloworld为模块名),会生成一个叫helloworld的目录和模板代码
3)进入helloworld目录，编辑mod_helloworld.c
4)运行apxs -c -i -a mod_helloworld.c libapr-1.lib libaprutil-1.lib libapriconv-1.lib libhttpd.lib，生成mod_helloworld.so
5)将mod_helloworld.so拷贝到Apache2.2\modules下
6)修改Apache2.2\conf\httpd.conf，在末尾加上
LoadModule helloworld_module \modules\mod_helloworld.so
<Location /helloworld>
setHandler helloworld
</Location>
7)启动apache，在IE里输入http://loacalhost/helloworld
/*
** mod_helloworld.c -- Apache sample helloworld module
** [Autogenerated via ``apxs -n helloworld -g'']
**
** To play with this sample module first compile it into a
** DSO file and install it into Apache's modules directory
** by running:
**
** $ apxs -c -i mod_helloworld.c
**
** Then activate it in Apache's httpd.conf file for instance
** for the URL /helloworld in as follows:
**
** # httpd.conf
** LoadModule helloworld_module modules/mod_helloworld.so
** <Location /helloworld>
** SetHandler helloworld
** </Location>
**
** Then after restarting Apache via
**
** $ apachectl restart
**
** you immediately can request the URL /helloworld and watch for the
** output of this module. This can be achieved for instance via:
**
** $ lynx -mime_header http://localhost/helloworld
**
** The output should be similar to the following one:
**
** HTTP/1.1 200 OK
** Date: Tue, 31 Mar 1998 14:42:22 GMT
** Server: Apache/1.3.4 (Unix)
** Connection: close
** Content-Type: text/html
**
** The sample page from mod_helloworld.c
