Question

我有问题XAMPP。当我尝试运行MySQL时，XAMPP显示了这一点：

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

我已将端口更改为3307 in C:\xampp\mysql\bin\my.ini 并在C:\xampp\php\php.ini到mysql.default_port=3307 mysqli.default_port=3307。

我还删除了ib_logfile1中的C:\xampp\mysql\data，但它仍然无效。错误日志：

感谢任何帮助。谢谢

Answer 1

MySQL告诉你它为什么无法启动：

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

因此我建议您首先要检查c：\ xampp \ mysql \ data是否存在且DBMS用户是否可写。

Answer 2

首先停止xampp控制面板上的服务，然后单击左侧的红叉以在您的计算机上安装该服务，然后图标将变成绿色标记，然后以管理员身份启动服务。

它应该正常工作。
