Создание базы, пользователя в MySQL, настройки доступа

Для MySQL создаем БД и настраиваем права доступа:

 
  mysql> CREATE DATABASE `mydb` CHARSET utf8 COLLATE utf8_general_ci;
  mysql> GRANT USAGE ON *.* TO 'webapp'@'localhost' IDENTIFIED BY 'SecretP@ssw0rd';
  mysql> GRANT ALL PRIVILEGES ON `mydb`.* TO 'webapp'@'localhost';
  mysql> flush privileges;
  mysql> SHOW GRANTS FOR webapp@localhost;
  +---------------------------------------------------------------------------------------------------------------+
  | Grants for webapp@localhost                                                                                   |
  +---------------------------------------------------------------------------------------------------------------+
  | GRANT USAGE ON *.* TO 'webapp'@'localhost' IDENTIFIED BY PASSWORD '*2470C0C06DEE42FD1618BB99005ADCA2EC9D1E19' |
  | GRANT ALL PRIVILEGES ON `mydb`.* TO 'webapp'@'localhost'                                                      |
