mysql 5.6.x error log InnoDB: Error: Table “innodb_table

mysql 5.6.x error log InnoDB: Error: Table “innodb_table_stats”not found解决办法

版本:mysql 5.6.x

错误提示:

InnoDB: Cannot open table mysql/innodb_table_stats from the internal data dictionary of InnoDB thou
gh the .frm file for the table exists. See http://dev.mysql.com/doc/refman/5.6/en/innodb-troubleshooting.html for how you can resolve
the problem.

出现这个提示总结起来有两种情况，一、mysql自带数据库mysql中Innodb引擎表损坏，二、从Mysql 5.5.x升级至5.6.x

MySQL 5.6的ibdata1表空间包含了5个InnoDB基础表,如下:

01	mysql> select table_name from information_schema.tables where table_schema='mysql' and engine='InnoDB';

02	+----------------------+

03	\| table_name \|

04	+----------------------+

05	\| innodb_index_stats \|

06	\| innodb_table_stats \|

07	\| slave_master_info \|

08	\| slave_relay_log_info \|

09	\| slave_worker_info \|

10	+----------------------+

11	5 rows in set (0.00 sec)

在MySQL 5.6之前,如果关闭MySQL后删除ibdata1,再重新启动MySQL的时候ibdata1会被重新创建. 但从MySQL 5.6开始,这5个表不会被重建.即使删除了ibdata1,下面的10个文件仍然保留在/data/mysql/mysql中(假如datadir = /data/mysql/):
innodb_index_stats.frm
innodb_index_stats.ibd
innodb_table_stats.frm
innodb_table_stats.ibd
slave_master_info.frm
slave_master_info.ibd
slave_relay_log_info.frm
slave_relay_log_info.ibd
slave_worker_info.frm
slave_worker_info.ibd

解决办法：删除/data/mysql/mysql/目录下5个数据表的表结构及数据文件，进入命令行中执行FLUSH TABLES;然后重新创建5个数据表，再接着查看mysql错误日志发现提示已经消失。
