最近在测试 nosql,安装了HandlerSocket之后,创建表主键为自增id,结果在 insert 的时候指定的ID,发生了冲突....报121 错误,google之后mysql 的121 是表创建异常...

这点做的有些不好,应该直接将mysql端的异常直接抛出来,方便用户定位问题.

另外mysql重启不使用my.cnf, 更改mysql的my.cnf后因为服务器数量太大,选择了覆盖...结果服务器起来之后最大连接只有100个....

原来是覆盖的时候 my.cnf 的其他用户给了 W权限,导致mysql 没有使用my.cnf 启动...

升级数据库 4.0 到5.0,有一台服务器出现问题,启动的时候竟然起了10多个进程...

原因是编译的时候使用了

--with-client-ldflags=-all-static \

--with-mysqld-ldflags=-all-static \

这个还需要在不同版本的NPTL上进行测试

MySQL: String Data Types and Indexing: Best PracticesMay 12, 2025 am 12:11 AM

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.
