解決策
セットアップではちゃんとしたパスワードを仮設定しておいてそのパスワードでまずはログイン
バリデーション機能が生きてると以下のように表示される
mysql> SHOW VARIABLES LIKE 'validate_password%'; +--------------------------------------+--------+ | Variable_name | Value | +--------------------------------------+--------+ | validate_password_dictionary_file | | | validate_password_length | 8 | | validate_password_mixed_case_count | 1 | | validate_password_number_count | 1 | | validate_password_policy | MEDIUM | | validate_password_special_char_count | 1 | +--------------------------------------+--------+
速攻削除
mysql> uninstall plugin validate_password;
mysql> SHOW VARIABLES LIKE 'validate_password%'; Empty set (0.00 sec)
やっためう!!
