基于Nginx0.8.54+PHP5.3.4+MySQL5.5.8的全新LNMP稳定版架构搭建的VPS

虽然开始在mysql5.5.8的编译过程中遇到了一些问题，因为之前从未接触过cmake方式的编译，在查阅官方手册并结合谷歌，终于把问题搞定了。

目前nginx的worker_processes设置为4，php-fpm设置为dynamic模式，max_children=32，start_servers=8，min_spare_servers=4，max_spare_servers=16，max_request=512的环境下，540mb内存剩余380mb，相比之前用zend server ce搭建的lamp内存开销，优化效果还是十分明显的，而且网站速度也很理想，给我最大的感受就是页面请求的响应速度比以前大大提升了。

鉴于mysql5.5.8这个新产品发布不久，网上的相关资料匮乏，补充一些自己在编译上的内容（注意，我因为自己对innodb无需求，因此屏蔽了innodb引擎，如果需要可以开启参数-dwith_innobase_storage_engine=1。

ps:如果在编译php的时候报错error while loading shared libraries: libmysqlclient.so.16: cannot open shared object file: no such file or directory，可以通过以下方法解决：

ln -s /usr/local/mysql/lib/mysql/libmysqlclient.so.16 /usr/lib/libmysqlclient.so.16
