1dbadd4/p7_1.jpg) ## 谈谈 MySQL 数据库那些事 MySQL 基本介绍 MySQL 优化方式 MySQL 技巧分享 Q & A ## MyISAM vs InnoDB ## MyISAM 特点 • 数据存储方式简单，使用 B+ Tree 进行索引 • 使用三个文件定义一个表：.MYI .MYD .frm • 少碎片、支持大文件、能够进行索引压缩 • 助 MySQL 缓解访问压力 ## 服务优化 ## MySQL 配置原则 - 配置合理的 MySQL 服务器，尽量在应用本身达到一个 MySQL 最合理的使用 - 针对 MyISAM 或 InnoDB 不同引擎进行不同定制性配置 ● 针对不同的应用情况进行合理配置 - 针对 my.cnf 进行配置，后面设置是针对内存为 16G 的服务器进行的合理设置 ## 服务优化 ## 公共选项 |---|---|---|---| |innodb\_buffer\_pool\_size|32M|10G|InnoDB 使用一个缓冲池来保存索引和原始数据，这里你设置越大，你在存取表里面数据时所需要的磁盘 I/O 越少，一般是内存的一半，不超过 2G，否则系统会崩溃，这个参数非常重要| |innodb\_additional\_mem\_pool\_size|2M|512M|InnoDB 用来保存 metadata
