Question

我在XAMPP 7.1.7上的MySQL数据库不再运行了。我尝试了这篇文章MySQL Database won't start in XAMPP Manager-osx中提出的众多解决方案但到目前为止没有运气。这是我尝试过的：

sudo /Applications/XAMPP/xamppfiles/bin/mysql.server start - ＆gt; 终端只是简单地说“错误！”
sudo killall mysqld - ＆gt;终端声明“未找到匹配的进程”
在XAMPP控制面板中将MySQL端口从3306更改为3307 - ＆gt;没有变化
在Monitor Activity工具中删除所有活动的mysql进程 - ＆gt;找不到任何名为“mysql”或“sql”

显然我不知道问题是什么，感觉我只是随机尝试我解决的每一个解决方案。

所以我在xamppfiles / var / mysql / [mycomputername] .home.err的日志文件下面发帖。也许这里有迹象表明问题可能是什么？

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!
