我们的一台服务器是来自一群国际黑客的勒索软件攻击的主题。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。
我们希望在新实例上恢复该数据，以便我们继续运行我的操作，但在尝试运行新安装的mysql后，服务停止，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，因为我需要访问此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
这没效果。所以我删除了只是日志文件，它创建了新的日志文件，它出现了这个错误

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

看来日志文件中有一个检查点是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大小。但我不知道如何去做。
任何帮助都会在这里派上用场。
在my.ini（或my.cnf）文件中，添加（或替换）以下行：
innodb_log_file_size = 1024M
