I have been working on my first project using databases using MySQL. 我一直在使用MySQL数据库进行我的第一个项目。 I woke up this morning unable to login to localhost. 我今天早上醒来，无法登录到本地主机。 I am able to enter root with no password and none of my databases are there. 我无需输入密码即可输入root，而且我的数据库都没有。 What should I do? 我该怎么办？

1 个解决方案

In theory root should have access to all your databases. 理论上，root应该可以访问您的所有数据库。 If you haven't deleted them, it's possible you just lost access to them. 如果您尚未删除它们，则可能是您失去了对其的访问权限。 Remember that MySQL is host-sensitive when logging in. 请记住，MySQL在登录时对主机敏感。

root@% , root@localhost , root@10.0.0.1 , etc... all may be assigned different permissions. root@% ， root@localhost ， root@localhost root@10.0.0.1等...都可以分配不同的权限。

You can try skip-grant-table in my.ini , as explained in this answer: 您可以在my.ini尝试skip-grant-table ，如以下答案中所述：

Regaining access to lost MySQL password for PHPMyAdmin on WAMP 重新获得WAMP上PHPMyAdmin丢失的MySQL密码的访问权限

With this you can reset the root password and try again. 这样，您可以重置root密码，然后重试。

If this does not yield effect, I would look into your SQL history and see if you haven't accidentally deleted them? 如果这没有效果，我将调查您的SQL历史记录，看看您是否意外删除了它们？
