某个mysql数据库服务器，运行了很久一直都很正常。因为从数据库服务器硬件损坏，需要重新导入数据库进行同步。再执行操作时，忘记输入选项-p（mysql -u root ）,居然直接进去了。吓得不轻啊。

赶紧登录进去，看是否存在密码为空的帐号,没查到啊？强制更改root密码，然后flush privilges。再试，还是可以不用密码登录。

查一下选项文件/etc/my.cnf，看是否有密码被直接写到文件里，还是没有。再拿find搜一把，发现目录/root里有文件 .my.cnf，打开看一下，其内容为：

[client]

user=root

password=i%^KgG76

删掉这个文件，再执行mysql，嘿嘿，进不去了吧！

这可能是某人为了方便调试数据库，隐藏了一个文件在这里。
