运行 MySQL 时出现 XAMPP 错误

Question

我有问题女巫 XAMPP。 当我尝试运行 MySQL 时，XAMPP 显示：

12:37:02  [mysql]   Error: MySQL shutdown unexpectedly.
12:37:02  [mysql]   This may be due to a blocked port, missing  dependencies, 
12:37:02  [mysql]   improper privileges, a crash, or a shutdown by another method.
12:37:02  [mysql]   Press the Logs button to view error logs and check
12:37:02  [mysql]   the Windows Event Viewer for more clues
12:37:02  [mysql]   If you need more help, copy and post this
12:37:02  [mysql]   entire log window on the forums

我已将C:\\xampp\\mysql\\bin\\my.ini和C:\\xampp\\php\\php.ini中的mysql.default_port=3307 mysqli.default_port=3307 。

我还删除了C:\\xampp\\mysql\\data ib_logfile1 ，但它仍然不起作用。 错误日志：

任何帮助表示赞赏。 谢谢

Answer 1

MySQL确切地告诉您为什么它无法启动：

[错误] InnoDB：无法创建C：\\ xampp \\ mysql \\ data \\ ib_logfile101

因此，我建议您要做的第一件事是检查c：\\ xampp \\ mysql \\ data是否存在并且可由DBMS用户写入。

Answer 2

首先在xampp控制面板上停止该服务，然后单击左侧的红叉以在您的计算机上安装该服务，然后该图标将变为绿色的勾号，然后以管理员身份启动该服务。

它应该工作正常。

Answer 3

1. 打开 XAMPP 控制面板并停止操作。
2. 打开服务，进入MySql80。
3. 停止服务。
4. 启动服务。
