Mysql server crash on start - mysql

Question

Mysql server crash on start on my Ubuntu 12.04.2 server. Mysql just not starting. Not after reboot, not after service mysql start(it return start: Job failed to start).
Previously it worked fine, but at some point the server crashed and I was not able to run it.

InnoDB: If the corrupt page is an index page
InnoDB: you can also try to fix the corruption
InnoDB: by dumping, dropping, and reimporting
InnoDB: the corrupt table. You can use CHECK

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 = 346064 K bytes of memory
Hope that's ok; if not, decrease some variables in the equation.
