【问题描述】:
检查error log的时候发现大量warnings:
[Warning] InnoDB Error Table mysql.innodb_index_stats not found
[Warning] InnoDB Error Table mysql.innodb_table_stats not found
[Warning] InnoDB Error Table mysql.slave_master_info not found
[Warning] InnoDB Error Table mysql.slave_relay_log_info not found
[Warning] InnoDB Error Table mysql.slave_worker_info not found

或在打开innodb表时,在err-log里会打印出:
 InnoDB: Error: Table "mysql"."innodb_table_stats" not found.
 Error: Fetch of persistent statistics requested for table "{databse_name}"."{table_name}" but the required system tables mysql.innodb_table_stats and mysql.innodb_index_stats are not present or have unexpected structure. Using transient stats instead.

【解决方案】:
先看看能否drop table,如果说表不存在,则继续下一步。

  1. DROP TABLE mysql.innodb_index_stats;

  2. DROP TABLE mysql.innodb_table_stats;

  3. DROP TABLE mysql.slave_master_info;

  4. DROP TABLE mysql.slave_relay_log_info;

  5. DROP TABLE mysql.slave_worker_info;


删除datadir下mysql数据库中的这五张表的frm文件(如有ibd也一并删除)

  1. rm -rf $datadir/mysql/innodb_index_stats.*

  2. rm -rf $datadir/mysql/innodb_table_stats.*

  3. rm -rf $datadir/mysql/slave_master_info.*

  4. rm -rf $datadir/mysql/slave_relay_log_info.*

  5. rm -rf $datadir/mysql/slave_worker_info.*


再执行如下语句,重新创建这五张表:

  1. USE mysql;

  2. CREATE TABLE `innodb_index_stats` (

  3.   `database_name` varchar(64) COLLATE utf8_bin NOT NULL,
