1 分库
1.1 按照功能分库
按照功能进行分库。常见的分成6大库:1 用户类库:用于保存了用户的相关信息。例如:db_user,db_system,db_company等。
2 业务类库:用于保存主要业务的信息。比如主要业务是笑话,用这个库保存笑话业务。例如:db_joke,db_temp_joke等。
3 内存类库:主要用Mysql的内存引擎。前台的数据从内存库中查找,速度快。例如:heap。
4 图片类库:主要保存图片的索引以及关联。例如:db_img_index,db_img_res。
5 日志类库:记录点击,刷新,登录等日志信息。例如:db_log_click,db_log_fresh,db_log_login。
6 统计类库:对业务的统计,比如点击量,刷新量等等。例如db_stat。
1.2 安装城市站分库
如果业务遍布全国,在按照功能分库库,每一个城市复制一份一模一样的库,只是库后缀都是城市名称。比如db_log_click_bj,db_log_click_tj,db_log_click_sh;2 分表
2.1 按照用户或业务的编号分表
对与用户或业务可以按照编号%n,进行分成n表。例如:笑话表。
tb_joke_01,tb_joke_02,tb_joke_03,tb_joke_04........
2.2 按照日期分表
对于日志或统计类等的表。可以按照年,月,日,周分表。例如 点击量统计。
tb_click_stat_201601,tb_click_stat_201602,tb_click_stat_201603
3 Mysql数据库常用架构
核心:一主多从,读写分离。

Mastering the method of adding MySQL users is crucial for database administrators and developers because it ensures the security and access control of the database. 1) Create a new user using the CREATEUSER command, 2) Assign permissions through the GRANT command, 3) Use FLUSHPRIVILEGES to ensure permissions take effect, 4) Regularly audit and clean user accounts to maintain performance and security.

Best practices for handling string data types and indexes in MySQL include: 1) Selecting the appropriate string type, such as CHAR for fixed length, VARCHAR for variable length, and TEXT for large text; 2) Be cautious in indexing, avoid over-indexing, and create indexes for common queries; 3) Use prefix indexes and full-text indexes to optimize long string searches; 4) Regularly monitor and optimize indexes to keep indexes small and efficient. Through these methods, we can balance read and write performance and improve database efficiency.

When selecting MySQL's BLOB and TEXT data types, BLOB is suitable for storing binary data, and TEXT is suitable for storing text data. 1) BLOB is suitable for binary data such as pictures and audio, 2) TEXT is suitable for text data such as articles and comments. When choosing, data properties and performance optimization must be considered.
