我启用了innodb_force_recovery = 1对mysql数据库进行损坏修复.但是mysql很不给面子,CPU一直在吃,但是就是不给我启动...导致我无法导出,并回复数据,请问目前如何是好呢
下面是错误的log

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=151
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 = 346079 K bytes of memory
Hope that's ok; if not, decrease some variables in the equation.
Thread pointer: 0x0
Attempting backtrace. You can use the following information to find out
where mysqld died. If you see no messages after this, something went
terribly wrong...
stack_bottom = 0 thread_stack 0x30000
The manual page at http://dev.mysql.com/doc/mysql/en/crashing.html contains
information that should help you find out what is causing the crash.
“You may have to recover from a backup”
要接受现实，并不是所有坏了的东西都能修好的
如果
innodb_force_recovery＝1不好使，你可以试试用2～6，再不行就dump一下然后重建。
