近期，测试环境出现了一次MySQL数据库不断自动重启的问题，导致的原因是强行kill -9 杀掉数据库进程导致，报错信息如下：
2019-07-24T01:14:53.769512Z 0 [Note] Executing 'SELECT * FROM INFORMATION_SCHEMA.TABLES;' to get a list of tables using the deprecated partition engine.

It is also possible that this binary or one of the libraries it was linked against is corrupt, improperly built, or misconfigured. This error can also be caused by malfunctioning hardware.
