无法打开表 mysql/innodb_index_stats

Question

在全新安装 XAMPP 并从我的 linux live db 导入到 windows 开发阶段后，我开始遇到INSERT. 其他一切似乎都运行良好。

我得到的错误mysql_error.log是：

2013-08-15 12:44:49 16c0 InnoDB: Error: Table "mysql"."innodb_table_stats" not found.
2013-08-15 12:44:49 16c0 InnoDB: Recalculation of persistent statistics requested for table "sizaradb"."pages" but the required persistent statistics storage is not present or is corrupted. Using transient stats instead.
2013-08-15 12:44:59 16c0 InnoDB: Error: Table "mysql"."innodb_table_stats" not found.
2013-08-15 12:44:59 16c0 InnoDB: Recalculation of persistent statistics requested for table "sizaradb"."translations" but the required persistent statistics storage is not present or is corrupted. Using transient stats instead.

mysql/innodb_index_stats尽管存在表的 .frm 文件，但我无法从 InnoDB 的内部数据字典打开表

我试图通过谷歌搜索错误并尝试查看其他人的修复来修复它，但它仍然无法正常工作。我已经为此工作了 2 天。

请帮我解决它。

问题

在 MySQL 5.6 中，架构中ibdata1包含 5 个 InnoDB mysql。

mysql> select table_name from information_schema.tables
    -> where table_schema='mysql' and engine='InnoDB';
+----------------------+
| table_name           |
+----------------------+
| innodb_index_stats   |
| innodb_table_stats   |
| slave_master_info    |
| slave_relay_log_info |
| slave_worker_info    |
+----------------------+
5 rows in set (0.00 sec)

mysql>

在 5.6 之前的 MySQL 版本中，如果您关闭 mysql、删除ibdata1并启动 mysql 备份，则会ibdata1重新创建。如果您使用 MySQL 5.6 执行此操作，则不会重新创建这 5 个表。即使您删除了ibdata1，以下 10 个文件仍在/var/lib/mysql/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

我很早就学会了这一点。对于新创建或损坏的ibdata1，这 5 个表没有对应的数据字典条目。

在您的特定情况下，我怀疑您ibdata1从 Linux 服务器复制到 Windows 服务器。MySQL/Windows 将期望数据字典具有 DOS 文件名格式。将其ibdata1移至 Windows，MySQL/Windows 无法与指向.frm和.ibd文件的 Linux 文件名和路径相关联。

解决方案

步骤 01：在另一个数据库服务器上安装 MySQL

步骤 02：mysqldump 只转储那 5 个表

TABLELIST="innodb_index_stats"
TABLELIST="${TABLELIST} innodb_table_stats"
TABLELIST="${TABLELIST} slave_master_info"
TABLELIST="${TABLELIST} slave_relay_log_info"
TABLELIST="${TABLELIST} slave_worker_info"
mysqldump -uroot -p mysql ${TABLELIST} > mysql_innodb_tables.sql

步骤 03：复制mysql_innodb_tables.sql到带有坏表的数据库服务器。

步骤 04：执行mysql_innodb_tables.sql

步骤 05：运行FLUSH TABLES;（可选）

试一试 ！！！

此错误已在 MySQL 论坛 ( 67179 ) 中报告，并在此处提及解决方案。请注意，在创建表之前，您应该进行清理

/* 
  temporary fix for problem with windows installer for MySQL 5.6.10 on Windows 7 machines.
  I did the procedure on a clean installed MySql, and it worked for me, at least it stopped
  lines of innodb errors in the log and the use of transient innodb tables. So, do it at
  your own risk..

  1. drop these tables from mysql:
     innodb_index_stats
     innodb_table_stats
     slave_master_info
     slave_relay_log_info
     slave_worker_info

  2. delete all .frm & .ibd of the tables above.

  3. run this file to recreate the tables above (source five-tables.sql).

  4. restart mysqld.
