MySQL innodb_table_stats表不存在的解決方案

MySQL innodb_table_stats表不存在的解決方案

MySQL 版本 5.6.14

公司有幾台MySQL伺服器的錯誤記錄檔顯示,有幾個系統資料表不存在.
innodb_table_stats
 innodb_index_stats
 slave_master_info
 slave_relay_log_info
 slave_worker_info

這是因為資料庫初始化的時候,dba可能刪除過ibdata1檔案
雖然重啟之後,資料庫會自動建立一個ibdata1檔案,但是上述系統資料表也是innodb引擎,所以不能訪問了.
這雖然不會影響業務,但是使用innobackupex備份的時候,會寫入錯誤記錄檔.
最後錯誤記錄檔裡,都是這種資訊.影響日常檢查。

 解決的方法.
1.刪除上述系統資料表
drop table mysql.innodb_index_stats;
 drop table mysql.innodb_table_stats;
 drop table mysql.slave_master_info;
 drop table mysql.slave_relay_log_info;
 drop table mysql.slave_worker_info;

 

 2.刪除相關的.frm .ibd檔案
rm -rf innodb_index_stats*
 rm -rf innodb_table_stats*
 rm -rf slave_master_info*
 rm -rf slave_relay_log_info*
 rm -rf slave_worker_info*

 

 3.重新建立上述系統資料表

 4.如果是Slave備機,停止複製,記錄pos等資訊
mysql> stop slave;
 Query OK, 0 rows affected (0.09 sec)

 5.重啟資料庫

6.如果Slave啟動報錯,則使用步驟4的資訊,重新change master

再刪除ibdata1檔案的時候,一定要想起系統資料庫還有5張innodb表...
