MySQLConnection ОШИБКА: доступ запрещен для пользователя 'rnd-admin' @ 'localhost' (используя пароль: ДА)

Question

Я пытаюсь подключиться к базе данных mysql на удаленном сервере через ssh туннель.
Когда соединение с сервером установлено, мой скрипт завершается с ошибкой mysql:

Примечание: Когда я подключаюсь к базе данных из терминала с теми же кредитами, используя mysql -u rnd-admin -p, то все в порядке, ошибок не обнаружено, и mysql cli открывается.

                db_config = read_db_config()
                conn = MySQLConnection(**db_config)

                cursor = conn.cursor()
                cursor.execute(query)
                result = cursor.fetchall()

                conn.commit()
                cursor.close()
                conn.close()

config.ini

[mysql]
host=127.0.0.1
port=3306
database=db-name
user=rnd-admin
password=pass

Answer 1

Исправлена ​​эта проблема путем удаления 3306 порта mysql по умолчанию из config.ini и ручной подачи port=tunnel.local_bind_port в MySQLConnection конструктор.

conn = MySQLConnection(**db_config, port=tunnel.local_bind_port)
