MySQLを5.1から5.6.10に上げたらなんか壊れた話

Pocket

おそらくMySQL5.1から5.6へ上げた影響だと思われるが、
ユーザの権限を設定することができなくなっていた。

mysql> grant all privileges on testdb.* to testuser@localhost identified by 'testpass';
ERROR 2013 (HY000): Lost connection to MySQL server during query

エラーログには以下のような文言がでていた。
バージョン違いのSQLをぶち込んだため、5.6で必要なテーブルがなくなったのかな。

InnoDB: Error: Table "mysql"."innodb_table_stats" not found.

これ以外にもエラーが出ているテーブルがたくさんあったが、
たぶんすべての原因はこいつ。

ググるとどうにもMySQLにバグ?っぽいので、
対応SQLファイルを取り込んでみる。

# mysql -u root -p -t mysql < five-tables.sql
# mysql -u root -p
mysql> grant all privileges on testdb.* to testuser@localhost identified by 'testpass';
ERROR 2013 (HY000): Lost connection to MySQL server during query

はい、ざんねーん。変わりません。
でもエラーログの内容は変わってました。

...

[ERROR] Native table 'performance_schema'.'events_statements_summary_by_host_by_event_name' has the wrong structure

データベースが壊れているっぽいですね。

上記URLを参考にすべてのDBをupgradeしてみる。
