InnoDB: Error: Table "mysql"."innodb_table_stats" not found索

InnoDB: Error: Table "mysql"."innodb_table_stats" not found.

导致：Seconds_Behind_Master: 27360  mysql主从同步停止

stop slave; 会一直卡住，service mysqld restart后，马上又会停止同步，出现同样问题。


初步判断：

因为innodb_table_stats表丢失，导致主从同步出现问题。


解决办法：

新建innodb_index_stats/innodb_tables_stats/slave_master_info/slave_relay_log_info/slave_worker_info索引表

或者：

将主mysql中的这5张表mysqldump重新导入。

Step 01 : Goto a DB Server running MySQL 5.6, or install MySQL 5.6 on a test machine.

Step 02 : mysqldump these 5 tables to a text file

INNODB_TABLES="innodb_index_stats"INNODB_TABLES="${INNODB_TABLES} innodb_table_stats"INNODB_TABLES="${INNODB_TABLES} slave_master_info"INNODB_TABLES="${INNODB_TABLES} slave_relay_log_info"INNODB_TABLES="${INNODB_TABLES} slave_worker_info"mysqldump -uroot mysql ${INNODB_TABLES} > InnoDB_MySQL_Tables.sql


前提需要先删除这5张表，在新建或者重新导入。

drop table xx yy uu ii;
