如問題標題所示，很顯然，我想從ibdata1文件恢復數據。我在Ubuntu系統中安裝了mysql並損壞了大約189GB的數據庫。現在數據庫不會再起來，並觸發數百萬的innodb日誌序列號錯誤。僅從ibdata1文件恢復數據
錯誤

我網上搜尋大量和嘗試了許多方法，如-innodb_force_recovery = N（1〜6）逐一與其他變化太大。但是DB不是要去啓動來恢復數據。
我已經清除了數據庫並恢復了舊備份，並且服務器已啓動並正在運行。但很少有數據非常重要，我想從ibdata1文件中恢復它。
有人可以指導我如何從ibdata1文件恢復數據？
這裏錯誤日誌可能會有幫助。

This could be because you hit a bug. It is also possible that this binary
or one of the libraries it was linked against is corrupt, improperly built,
or misconfigured. This error can also be caused by malfunctioning hardware.
We will try our best to scrape up some info that will hopefully help
diagnose the problem, but since we have already crashed,
something is definitely wrong and this may fail.
key_buffer_size=16777216
read_buffer_size=131072
max_used_connections=0
max_threads=500
thread_count=0
connection_count=0
It is possible that mysqld could use up to
key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 1110145 K bytes of memory
Hope that's ok; if not, decrease some variables in the equation.
