InnoDB：错误：升级到 mysql 5.6 后找不到表“mysql”.“innodb_table_stats”

Question

我从 5.5 升级到 mysql 5.6，现在我的日志在启动时到处都是这样的消息

我在这里找到了一个可能的解决方案，但它似乎不是官方的。 http://forums.mysql.com/read.php?22,578559,579891#msg-579891

任何官方解决方案或 100% 修复？

我之前在：Cannot open table mysql/innodb_index_stats 中解决了这个问题

这些表是在您安装 MySQL 5.6 时为您创建的。但是，从 MySQL 5.5 升级不会调用这些表的创建。以下是手动创建它们的脚本：

innodb_index_stats

USE mysql;
CREATE TABLE `innodb_index_stats` (
  `database_name` varchar(64) COLLATE utf8_bin NOT NULL,
  `table_name` varchar(64) COLLATE utf8_bin NOT NULL,

另一种解决方法是从 MySQL 5.6 实例创建脚本。

步骤 01：转到运行 MySQL 5.6 的 DB Server，或在测试机器上安装 MySQL 5.6。

步骤02：mysqldump这5个表到一个文本文件

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

然后，您可以InnoDB_MySQL_Tables.sql在升级前在任何运行 MySQL 5.5 的数据库服务器上运行。

Answer 2

罗兰多的回答对我有用，但有一些补充。我遇到了同样的问题，这 5 个表通过 SHOW TABLES 显示，但是表上的 SELECT 或其他操作导致找不到表。

为了解决这个问题，使用 Rolando 的回答，我需要：

• DROP TABLE <tablename> -- 所有 5 个表

• 在文件系统中，删除剩余的 .ibd 文件（.frm 文件已被删除DROP TABLE）

• 然后我停止并启动了 mysqld 实例（不知道是否需要它 - 让我很高兴）

• CREATE TABLERolando 提供的声明然后运行没有问题。
