有时，磁盘空间不够用了，可能要删除几个mysql-bin，其后果可能是造成mysql无法启动。

如可能出现下面的提示：

1.140211 16:12:03 [Note] Recovering after a crash using mysql-bin2.140211 16:12:03 [Note] Starting crash recovery...3.140211 16:12:03 [Note] Crash recovery finished.4.140211 16:12:03 - mysqld got signal 11 ;5.This could be because you hit a bug. It is also possible that this binary6.or one of the libraries it was linked against is corrupt, improperly built,7.or misconfigured. This error can also be caused by malfunctioning hardware.8.We will try our best to scrape up some info that will hopefully help diagnose9.the problem, but since we have already crashed, something is definitely wrong10.and this may fail.11. 12.key_buffer_size=013.read_buffer_size=209715214.max_used_connections=015.max_connections=150016.threads_connected=017.It is possible that mysqld could use up to 18.key_buffer_size + (read_buffer_size + sort_buffer_size)*max_connections = 7680000 K19.bytes of memory20.Hope that's ok; if not, decrease some variables in the equation.

解决办法是把mysql-index文件中多余的内容删除即可
