This may be due to a blocked port, missing dependencies,
improper privileges, a crash, or a shutdown by another method.

我看了多个视频，但没有一个能告诉我如何解决这个问题。我以前也遇到过这种情况，我只是重新安装了 xammp，一切正常。但是这次我不想这样做，而是重新创建我的数据库。我想知道如何修复它。另外，如果有更好的地方可以问这个问题，请告诉我。
答案1
ibtmp1' 的大小为 12 MB。物理上写入文件完整
增加该文件的设置。
寻找需要巨大临时表的复杂查询。
缓冲池，总大小 = 16M
这个值太小了。你有多少 RAM？
