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.
To report this bug, see
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.
Server version: 5.5.36-MariaDB-1~precise-log
key_buffer_size=67108864
read_buffer_size=131072
max_used_connections=0
max_threads=1002
thread_count=0
It is possible that mysqld could use up to
key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 2263780 K bytes of memory
Hope that's ok; if not, decrease some variables in the equation.

大家好，我创建了备份：innobackupex --defaults-extra-file=/etc/mysql/my.cnf --host=localhost --password= --socket=/var/run/mysqld/mysqld.sock /mnt /临时备份/
rsync 到复制框：rsync -avz --progress
恢复：innobackupex --copy-back /mnt/tempdisk/
innobackupex: 开始复制 InnoDB 系统表空间 innobackupex: in '/mnt/tempdisk' innobackupex: back to original InnoDB data directory '/var/lib/mysql' innobackupex: Copying '/mnt/tempdisk/ibdata1' to '/var/lib /mysql/ibdata1'
innobackupex: 开始复制 InnoDB 撤消表空间 innobackupex: in '/mnt/tempdisk' innobackupex: back to '/var/lib/mysql'
innobackupex: 开始复制 InnoDB 日志文件 innobackupex: in '/mnt/tempdisk' innobackupex: 回到原始 InnoDB 日志目录 '/var/lib/mysql' innobackupex: 完成复制回文件。
