我们的一台服务器遭到来自一群国际黑客的勒索软件攻击。所以我们重新分组并重新开始，我们唯一不受影响的数据是存储在 mysql 程序数据文件夹中的 ibdata1 文件。
我们想在新实例上恢复该数据，以便我们继续我们的操作，但在尝试运行新安装的 mysql 后，服务停止并出现错误 1067。它建议删除 InnoDB 创建的所有文件：所有 ibdata 文件和所有 ib_logfile 文件。如果我这样做，服务将运行，但我不能这样做，因为我需要访问这个特定数据文件中的数据。我还在 .cnf 文件中添加了这两行
innodb_force_recovery=6
innodb_fast_shutdown=0
那没有奏效。所以我只删除了日志文件，它创建了新的日志文件，随之而来的是这个错误

Then I replaced the log files with the same ones I used with the original ibdata1 file then I got this error.

日志文件中的某处似乎有一个检查点，这是 mysql 服务正确读取数据文件所必需的。也许我需要在 my.ini 配置文件中指定日志文件的大小。但我不知道该怎么做。
任何帮助都会在这里真正派上用场。
