Question

我只是为Win64安装了XAMPP 7.3.6-2-VC15，当我安装它时，一切正常，MySQL从控制面板启动而没有错误，一切都很好。

重新启动我的PC后，Apache仍然可以运行，但是MySQL拒绝启动！我尝试重新安装XAMPP，但完全相同。 MySQL工作正常，并在重新启动后停止工作。

这是我有的几条日志...

在控制面板中：

09:48:10  [mysql]   Attempting to start MySQL app...

09:48:11  [mysql]   Status change detected: stopped

我尝试以下方法：

将端口更改为3306以外的端口=>没有成功
以管理员身份运行xamp控制面板=>失败
删除临时表ibdata1和ibtmp1 =>没有成功

如果有人有主意...

编辑：我尝试以管理员身份通过管理面板安装为Windows服务。因此，我在日志中有一些新行。似乎用户表已损坏...我该如何修复？

Answer 1

我遇到了像你这样的问题。我已经解决了如下问题。

Copy from xampp/mysql/backup folder and paste in xampp/mysql/data folder except ibdata1 file.

如果从xampp / mysql / data替换ibdata1文件，则您将得到的错误表不存在。

Answer 2

这对我有帮助：

从控制面板打开外壳，并使用以下命令启动mysql：

mysqld –-console –-skip-grant-tables –-skip-external-locking

从控制面板中打开另一个外壳，并使用以下命令修复数据库：

mysqlcheck -r --databases mysql --use-frm

停止mysql，关闭外壳并正常重启mysql。
