MySql 崩溃，无法为缓冲池分配内存

Question

时不时地，我的 MySQL 数据库在我的 Ubuntu 服务器上崩溃并且无法自动恢复。 然后我必须重新启动 AWS 实例。 当我查看数据库日志文件时，我看到“无法分配内存”和稍后的“中止”。 不知道我需要做什么来解决这个问题。

当我们注意到这个问题时，我们在 2020-09-05T02:25:00 重新启动了实例，数据库服务器再次启动。 然而它抱怨表被标记为崩溃，但所有这些表都工作得很好。

Answer 1

您没有足够的可用内存来适应 innodb_buffer_pool_size

因此，您可以增加服务器中的内存或减少参数，直到它适合您在 mysql.ini/cnf 文件中的系统。 例如 100 MB 如图所示

innodb_buffer_pool_size=100M
