php - MySQL 错误 InnoDB : Warning

Question

为什么会出现这个错误？

2017-06-15 05:54:42 1848 InnoDB: Warning: Using innodb_additional_mem_pool_size is DEPRECATED. This option may be removed in future releases, together with the option innodb_use_sys_malloc and with the InnoDB's internal memory allocator.

InnoDB only wrote those files full of zeros, but did not yet use them in any way. But be careful: do not remove old data files which contain your precious data!

从 mySql 切换到 MariaDB 后，我遇到了类似的问题，输出中列出的一些错误是相同的。我希望我的解决方案也适用于您(因为您没有提供有关该问题的太多背景信息)。

我的问题是我没有使用以下命令初始化数据库用户:

$ mysql_install_db --user=mysql --basedir=/usr --datadir=/var/lib/mysql

运行后，我解决了这个错误

[ERROR] Could not open mysql.plugin table. Some plugins may be not loaded

当我再次启动数据库时，它工作得很好。
