MYSQL XAMPP 中的 v3.3.0 未启动，运行 直到昨天都还好 HY2006 错误
MYSQL in XAMPP v3.3.0 is not starting, was running fine till yesterday HY2006 error
昨天运行突然从今天早上开始就崩溃了。
我附上了错误日志，我们将不胜感激。
我还试图找出是否有任何进程使用以下命令使用此端口：netstat -aon | findstr 3306，但它 returns 什么都没有，这意味着端口是空的。

我终于让它以某种方式工作，不，我没有卸载它或重新安装它。目前运行良好，过程如下：
- 去了C:\xampp_php8\mysql，我的xampp mysql的根文件夹：
- 已将 data 文件夹重命名为 data_blah 等等...
- 创建了新的 data 文件夹，复制并粘贴了 backup 的所有内容
此数据文件夹
中的文件夹
- 开始 xampp、apache、mysql、https://localhost/phpmyadmin,
这里一切正常。
- 已停止 xampp，仅复制了我需要的 数据库文件夹 &
ib_logfile0、ib_logfile1 和 ibdata1 来自旧数据目录和
粘贴到新的数据目录中。
- 已启动 xampp、apache、mysql，一切似乎都很好，但 INSERT
缺少权限。
- 最后，按下清空会话数据
https:///localhost/phpmyadmin/index.php.
现在一切正常。
昨天运行突然从今天早上开始就崩溃了。
我附上了错误日志，我们将不胜感激。
我还试图找出是否有任何进程使用以下命令使用此端口：netstat -aon | findstr 3306，但它 returns 什么都没有，这意味着端口是空的。

我终于让它以某种方式工作，不，我没有卸载它或重新安装它。目前运行良好，过程如下：
- 去了C:\xampp_php8\mysql，我的xampp mysql的根文件夹：
- 已将 data 文件夹重命名为 data_blah 等等...
- 创建了新的 data 文件夹，复制并粘贴了 backup 的所有内容 此数据文件夹 中的文件夹
- 开始 xampp、apache、mysql、https://localhost/phpmyadmin, 这里一切正常。
- 已停止 xampp，仅复制了我需要的 数据库文件夹 & ib_logfile0、ib_logfile1 和 ibdata1 来自旧数据目录和 粘贴到新的数据目录中。
- 已启动 xampp、apache、mysql，一切似乎都很好，但 INSERT 缺少权限。
- 最后，按下清空会话数据 https:///localhost/phpmyadmin/index.php.
现在一切正常。
