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=8388608  
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 = 68241 K bytes of memory  
Hope that's ok; if not, decrease some variables in the equation.

问题分析：应该是数据在断电的时候可能造成innodb数据损坏试着将数据存放目录下ib\_logfile0 ib\_logfile1两个日志文件做好备份删除掉（先把数据和配置文件备份一下防止乱弄把数据全弄坏了 然后再用副本试着恢复）。重启mysql能启动了，不过是一会就会出现原来的问题。继续查看错误日志

错误如下：

innoDB是可以启动的，说日志序列号和ibdata文件中的不匹配！继续删除数据存放目录下ibdata1文件（删除前做好备份）

执行service mysqld start 启动正常……
