"MySQL5.5参考手册,涵盖了MySQL5.5至5.5.39的使用方法和性能优化,包括基于NDBCLUSTER 7.2版本的MySQL集群"
MySQL是世界上最流行的开源关系型数据库管理系统之一。此文档,即MySQL5.5参考手册,详细阐述了MySQL 5.5系列的各个方面,从基础操作到高级特性,旨在为用户提供全面的指南。手册包含了从基础查询语言到复杂的存储过程、触发器、视图等数据库设计元素的详细信息。
手册特别提到了MySQL 5.5引入的一些新特性,这些特性可能并非在所有版本中都可用。这意味着某些特性可能是特定于企业版或有特定授权限制的。如果你对所使用版本包含的功能有疑问,应查阅你的MySQL 5.5许可协议,或者联系你的Oracle销售代表获取确切信息。
对于每个版本的具体更新和改进,手册建议参考MySQL5.5的发行说明,这里列出了每一次发布中的详细变更记录。
此外,手册还覆盖了法律信息,确保用户在使用MySQL时遵守所有适用的条款和规定。文档生成日期为2014年6月28日,修订号为39189,表明它是当时最新的官方参考资料。
对于不同类型的用户,手册提供了针对性的章节:
- 通用部分:适用于所有用户的基础知识,如SQL语句、数据类型和索引。
- 管理员部分:包含服务器管理、性能调优、备份与恢复等高级主题。
- MySQL企业版:针对使用企业版的用户,可能包括额外的监控和安全特性。
- 开发者和功能:面向编写应用程序的开发者,讨论API、连接器和开发工具。
- 连接器和APIs:详细介绍了与MySQL交互的各种编程语言的接口。
- 高可用性与可扩展性:提供有关集群配置、复制和故障切换的指导。
- 安装与升级:帮助用户安装和升级MySQL服务器的步骤和注意事项。
- 服务器管理:涵盖数据库的日常维护和管理任务。
- 使用未经打包的安装程序进行安装:对于喜欢手动配置的高级用户,提供了自定义安装的方法。
这个手册是MySQL 5.5用户的宝贵资源,无论你是初次接触还是经验丰富的DBA,都能从中找到所需的详尽信息和实践指导。
