一、前言

   LAMP即Linux+Apache+Mysql+PHP，一组常用来搭建动态网站或者服务器的开源软件，本身都是各自独立的程序，但是因为常被放在一起使用，拥有了越来越高的兼容度，共同组成了一个强大的Web应用程序平台。随着开源潮流的蓬勃发展，开放源代码的LAMP已经与J2EE和.Net商业软件形成三足鼎立之势，并且该软件开发的项目在软件方面的投资成本较低，因此受到整个IT界的关注。从网站的流量上来说，70%以上的访问流量是LAMP来提供的，LAMP是最强大的网站解决方案．

   WordPress是一种使用PHP语言开发的博客平台，用户可以在支持PHP和MySQL 数据库的服务器上架设属于自己的网站。也可以把 WordPress 当作一个内容管理系统（CMS）来使用。WordPress 是一个免费的开源项目，在GNU通用公共许可证下授权发布。WordPress 被认为是Michel Valdrighi所开发的网志平台b2/cafelog的正式继承者。“WordPress”这个名字出自 Christine Selleck 的主意，他是主要开发者Matt Mullenweg的朋友。

   phpMyAdmin 是一个以PHP为基础，以Web-Base方式架构在网站主机上的MySQL的数据库管理工具，让管理者可用Web接口管理MySQL数据库。借由此Web接口可以成为一个简易方式输入繁杂SQL语法的较佳途径，尤其要处理大量资料的汇入及汇出更为方便。其中一个更大的优势在于由于phpMyaAdmin跟其他PHP程式一样在网页服务器上执行，但是您可以在任何地方使用这些程式产生的HTML页面，也就是于远端管理MySQL数据库，方便的建立、修改、删除数据库及资料表。也可借由phpMyAdmin建立常用的php语法，方便编写网页时所需要的sql语法正确性。

二、环境

软件包：

wordpress-3.9-zh_CN.zip               wordpress主文件
