按照市面上常见的vista下iis7 php mysql安装的步骤，一步步完成安装。phpinfo正常，mysql命令行管理也一切正常，但就是安装discuz就会出问题，明显是php与mysql协同出现问题，这个问题在2003上从来没出现过。
最后去国外的官方网站查找，给出的结果是如果是在没有找到问题libmysql.dll拷贝到system32。根据我的经验，system32拷贝不是必须，只是为了不用设置环境变量。但本案例中环境变量已经做了设置，看来vista限制了某些不明来历读取环境变量的请求。
此次故障排除总结：如果php正常，mysql命令操作也正常，但就是php操作mysql返回网页可能不可用等错误页面时候，把libmysql.dll拷贝到system32试一下。同时装iis7和apache2的，可以在apache的httpd.conf里把监听端口改为与iis7不冲突的8080等端口。
附一个不错的phpinfo指针
