抱歉,我的英语不流利。我是MySQL数据库的新手。我在 Windows Server 2022 Datacenter 上使用 MySQL 8.0.30。我有一个问题,MySQL 经常崩溃(MySQL 服务停止),并且总是带有相同的错误日志。我试图找到问题的根源,但没有解决。

有关信息,我在具有以下规格的同一设备上使用了 Grafana Web Server 和 MySQL: 处理器 Intel(R) Xeon(R) Silver 4208 CPU @ 2.10GHz 2.10 GHz 已安装 RAM 16.0 GB(15.6 GB 可用) 系统类型 64位操作系统,基于x64的处理器

请给我建议来解决这个问题。 先谢谢了

这是错误 MySQL 日志详细信息:

Most likely, you have hit a bug, but this error can also be caused by malfunctioning hardware.
Thread pointer: 0x0
Attempting backtrace. You can use the following information to find out

我尝试减少数据读写,然后增加客户端连接限制

每秒速率 = RPS

为您的 my.ini [mysqld] 部分考虑的建议,以避免意外关闭。

innodb_thread_concurrency=10  # from 33 for reasonable limit for your 16 available total threads 
innodb_redo_log_capacity=96M  # from innodb_log_file_size name and 48M limit

**** 这是当前名称,而不是已弃用的每个错误日志的 innodb_log_file_size

innodb_buffer_pool_size=8G  # from 124M for about 1/2 available RAM to reduce innodb_data_reads RPS of 31.
read_rnd_buffer_size=32K  from 256K to reduce handler_read_rnd_next RPS of 63,041
thread_cache_size=128  # from 10 to reduce threads_created RPS of ~ 5

请查看个人资料以获取联系信息。您有很多机会通过额外的全局变量更改来提高性能。
