我在 win10 机器上使用 xampp 运行 mysql 时遇到问题。 这是 xampp 消息:
Error: MySQL shutdown unexpectedly.
1:33:01 [mysql] This may be due to a blocked port, missing dependencies,
1:33:01 [mysql] improper privileges, a crash, or a shutdown by another method.

这是我的 mysql.log:

InnoDB only wrote those files full of zeros, but did not yet use them in any way. But be careful: do not remove old data files which contain your precious data!

我尝试重新初始化 mysql 数据文件夹，从中删除 ibdata1、ib_log 文件，但没有成功。 非常感谢任何建议。
最佳答案
通过安装 5.6.35/PHP 5.6.35 - XAMPP 解决
使用 windows 10，xampp 7.2.2 有同样的问题。
- 备份了 htdocs 项目
- 已卸载 XAMPP 7.2.x
- 已安装 XAMPP 5.6.x
- 将备份项目粘贴到 htdocs
- 遇到Apache端口号问题，然后在httpd.conf中将80改成8080
- 工作正常!
