【MySQL】5.6.x InnoDB Error Table mysql.innodb_table_stats not found

MySqlError
【問題描述】：
檢查error log的時候發現大量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

或在開啟innodb表時，在err-log裡會列印出：
 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.

【解決方案】：
先看看能否drop table，如果說表不存在，則繼續下一步。
  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;

刪除datadir下mysql資料庫中的這五張表的frm檔案（如有ibd也一併刪除）
  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.*

再執行如下語句，重新建立這五張表：
  1. USE mysql;

最後重啟mysqld即可。


可能形成這種問題的原因是做了形如rm -rf ibdata ib_logfile0 等操作。
