MySQL:使用源码分发版还是二进制分发版
选择了MySQL的安装版本后，要做的第二项决策是你是使用源码分发版还是二进制分发版。大多数情况，如果你的平台上已经有了一个二进制分发版，你可能使用二进制分发版。大多数平台可以使用原格式二进制分发版，例如Linux使用RPM文件，Mac OS X使用DMG安装软件
选择了MySQL的安装版本后，要做的第二项决策是你是使用源码分发版还是二进制分发版。大多数情况，如果你的平台上已经有了一个二进制分发版，你可能使用二进制分发版。大多数平台可以使用原格式二进制分发版，例如Linux使用RPM文件，Mac OS X使用DMG安装软件包。也可以使用Zip文件或压缩tar文件。
选择二进制分发版的理由：
◆ 二进制分发版比源码分发版更容易安装。
◆为了满足不同用户的需求，我们提供了两种不同的二进制版本：一个是编译过的带非事务储存引擎(小的快速库)，另一个配置了最重要的扩展选项，例如事务安全表。两个版本均从相同的源码分发版编译而来。所有本地MySQL客户端均可以连接任一版本的MySQL服务器。扩展MySQL库分发版标有-max后缀，配置了与mysqld-max相同的选项。如果想要使用MySQL-Max RPM，必须首先安装标准MySQL-server RPM。
在某些环境下，最好安装源码分发版MySQL：
◆ 你想要在某个明显的位置安装MySQL。标准二进制分发版可以安装到任何地方，但你想更加灵活地将MySQL组件放到某个地方。
◆ 你想要将mysqld配置一些标准二进制分发版中未包括的一些特殊特征。下面是一些你想要使用的最常用的选项：
◆--with-innodb(在所有MySQL 5.1库版本中默认使用)
◆--with-berkeley-db(只适合部分平台)
◆--with-libwrap
◆--with-名d-z-libs(适合部分二进制)
◆--with-debug[=full]
◆ 你想要将mysqld配置一些标准二进制分发版中已经包括的一些特殊特征。例如，一般编译过的分发版支持所有字符集。如果你想要一个更小的MySQL服务器，可以重新编译只支持你需要的字符集。
◆ 你有一个专用编译器(例如pgcc)或想要使用更好地优化适用你的处理器的编译器选项。二进制分发版编译的选项适合同一处理器族的各种处理器。
◆ 你想要使用BitKeeper库中的最新源码，以访问所有最新漏洞修复。例如，如果你发现了漏洞并将它报告给MySQL开发小组，漏洞修复传递给源码库，你便可以访问它。发布实际发行后才会出现漏洞修复。
◆ 如果你想要阅读(或修改)构成MySQL的C和C++代码，你应该拿到源码分发版。源码总是最终的手册。源码分发版也比二进制的分发版包含更多的测试和实例。

MySQL query performance can be optimized by building indexes that reduce lookup time from linear complexity to logarithmic complexity. Use PreparedStatements to prevent SQL injection and improve query performance. Limit query results and reduce the amount of data processed by the server. Optimize join queries, including using appropriate join types, creating indexes, and considering using subqueries. Analyze queries to identify bottlenecks; use caching to reduce database load; optimize PHP code to minimize overhead.
