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=262144
max_used_connections=1
max_threads=151
thread_count=1
connection_count=1
It is possible that mysqld could use up to
key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 134066 K bytes of memory
Hope that's ok; if not, decrease some variables in the equation.

如果您尝试了每个innodb_force_恢复值，3停止回滚或转发事务，那么我只能指出以下几点 切中要害的是，这个网页上的人最终删除了innodb文件 直到最后，我还没有找到解决这个问题的明确方法……但是如果您在测试环境中，您可以删除ibdata1和ib_logfile0、ib_logfile1并重新启动服务器。这在我的情况下奏效了 显然，如果您有大量其他数据库，这将涉及到备份和恢复这些数据库。如果你有别的办法，我建议你先试试 Percona提供了一套数据恢复工具，但在您的情况下，数据不是问题所在
