我的服务器好像被入侵了，mysql数据及文件无故丢失

Question

mysql数据中的一个库无故丢失一些表的内容，及与这个表有关的文件（已经上传的文件）。出现频率3-5一次，

目前修改了mysql的root密码，及oodxyancp的密码。刚刚才修改的。其他的没发现异常，数据库中var/*.err这个文件没有异常。

/var/log/message的日志内容

Answer 1

从这里没看出数据库的问题
你查看下数据库文件是否缺少还是表结构出了问题？

Answer 2

你好！ 数据库文件没有缺少，。 表结构也没问题，

恢复到前一天的数据就正常了，，期间我们没有对数据库作任何修改

Answer 3

会不会和磁盘有关系？
