1つのmysqlを除くすべてのデータベースで選択を許可

MS Windows 2008R2でtest_userの下にMySQL 5.5.17というユーザーを作成しました。MySQLデータベースを除くすべてのデータベースでこのユーザーに選択権限を付与したいのですが、このインスタンス内に約200のデータベースがあることに注意してください。

次のクエリの出力を実行します。

SELECT CONCAT("GRANT SELECT ON ",SCHEMA_NAME,".* TO 'test_user'@'localhost';")
FROM information_schema.SCHEMATA 
WHERE SCHEMA_NAME NOT LIKE 'mysql';

200個のデータベースがあり、1つずつ付与したくない場合。それを行う最速の方法は

GRANT SELECT ON *.* TO 'test_user'@'localhost';
FLUSH PRIVILEGES;

そして、mysql dbで特権を取り消すだけです

REVOKE SELECT ON mysql.* FROM 'test_user'@'localhost' ;
FLUSH PRIVILEGES;

しかし、mysql。*で選択的にGRANTしてからREVOKEすると、その後、それは働いています

数年後、MariaDBで。私がやること：

  • すべてのデータベースへのアクセスを許可する
  • mysqlに「LOCK TABLES」のみを付与します。*

ユーザーはmysqlを表示できますが、テーブルは表示できません。ユーザーはどのテーブルにもアクセスできないため、テーブルのロックは機能しません。
