前段时间出差在现场开发的时候，导入MySQL数据库老是出问题。最后发现了一个神奇sql语句交给实施，只要导入出错就把如下语句执行就可以了。至今屡试不爽。

set global max_allowed_packet=100 000 000;
set global net_buffer_length=100000;
SET GLOBAL interactive_timeout=28800 000;
SET GLOBAL wait_timeout=28800000

以上语句的解释：

–max_allowed_packet=XXX 客户端/服务器之间通信的缓存区的最大大小;

–net_buffer_length=XXX TCP/IP和套接字通信缓冲区大小,创建长度达net_buffer_length的行

interactive_timeout = 10; 对后续起的交互链接有效；

wait_timeout 对当前交互链接有效；

=============================================

以上语句主要解决：连接超时，导入的sql文件过大。

Explain the InnoDB Buffer Pool and its importance for performance.Apr 19, 2025 am 12:24 AM

InnoDBBufferPool reduces disk I/O by caching data and indexing pages, improving database performance. Its working principle includes: 1. Data reading: Read data from BufferPool; 2. Data writing: After modifying the data, write to BufferPool and refresh it to disk regularly; 3. Cache management: Use the LRU algorithm to manage cache pages; 4. Reading mechanism: Load adjacent data pages in advance. By sizing the BufferPool and using multiple instances, database performance can be optimized.
