服务中缺少 MySql - 无法打开 innodb_index_stats.ibd

Question

我在 Windows 10 上安装了 Ampps 3.7，当 Apache 运行正常时，Mysql 将不再启动；它曾经运行正常，但现在有一个 innidb 错误。我的问题和here的问题类似，只是我没有升级mysql，建议的解决方法是删除并恢复几个inno_db表。但是，当我无法连接到 mysql 时，我该怎么做

我读过 this 和 this 都说将以下内容添加到 my.ini

innodb_force_recovery = 1

Ampps Mysql 错误日志说：

有什么想法吗？

更新：

删除 2 ib_logfile 的最初工作，但后来他们重新出现（可能在重新启动后）。通过再次删除 2 个文件，我能够启动 mysql，但列出了以下错误：

删除日志文件显然不能解决根本原因。

似乎我不是唯一一个对MySql on Ampps 有问题的人。

Answer 1

答案here 对我有用：

open the following folder
Ampps/mysql/data/
delete all files like ib_logfile** and mysql-bin.index,mysql-bin.****,
then start or restart MySQL via the AMPPS pannel

对我来说只有 2 个 ib_logfile。

Answer 2

我遇到了完全相同的问题，并通过将innodb_force_recovery = 1 添加到 my.ini 来解决它，正如您指出的那样。不要忘记：

1. 保存配置并重启 MySQL。
2. 现在停止 MySQL，删除刚刚添加的行并重新启动 MySQL。

注意：您也可以简单地将 innodb_force_recovery 的值更改为 0 而不是删除它

正如您在此处指出的link 所暗示的，这非常重要

这对我来说是最好的解决方案，不像那些需要你在 mysql 甚至无法启动 O.o 时运行 sql 查询的解决方案
