После выбора pdf файла 5 мб в LONGBLOB выдает ошибку 1105 в MySQL workbench, хотя в max_allowed_packet ставила 50000000(50 мб), перезапускала сервер. Не помогает.
По данному форуму нашла похожий вопрос, но автор не написал, как решил проблему:

max_allowed_packed 50000000

Из документации mysql.ru:


LONGBLOB, LONGTEXT

Столбец типа BLOB или TEXT с максимальной длиной 4294967295 (2^32 - 1) символов. See Раздел 6.5.3.1, «Молчаливые изменения определений столбцов». Следует учитывать, что в настоящее время протокол передачи данных сервер/клиент и таблицы MyISAM имеют ограничение 16 Мб на передаваемый пакет/строку таблицы, поэтому пока нельзя использовать этот тип данных в его полном диапазоне. See Раздел 6.2.3.2, «Типы данных BLOB и TEXT».

InnoDB тип таблицы

Скачала вчера MySQL и workbench(версия от 08.02.2017)
Вот результат запроса SHOW VARIABLES LIKE 'max_allowed_packed'

Пробую так:
http://help.stakhanovets.ru/question/details/id/553769

В терминале sudo nano /etc/my.cnf
[mysqld]
max_allowed_packet = 10000000
innodb_buffer_pool_chunk_size = 134217728

А в workbench после SHOW VARIABLES LIKE 'max_allowed_packet' ничего не выводит, не смотря на аналогичные настройки

Написала в поддержку MySQL.com(ORACLE)

show variables like 'max_allowed_packet'
4194304

Переустановила Mysql. В терминале show variables like 'max_allowed_packet' 4194304.
В GUI по такому же запросу -4194304. В настройках GUI 10000000.

Ищу как найти поменять значение max_allowed_packet через терминал. должен быть файл my.cnf. Он у меня в /etc/my.cnf(там 10000000). Но не на сервере Mysql, поэтому не виден. Как на самом сервере поменять - не нашла.

Нашла как найти файл my.cnf
Но не могу понять выражение "добавить в секцию [mysqld]."
Помогите

У меня по этому пути /etc/mysql/my.cnf - игнорируется

Перезагрузила MYSQL 5.7.1
Нашла, что надо из файла my-default.cnf скопировать настройки в файл my.cnf.
sudo cp /usr/local/mysql/support-files/my-default.cnf /etc/my.cnf

В настройках не было max_allowed_packet = 16M
Я сама внесла эту запись в [mysqld]
Вот my.cnf:

-------------
Но настройка не сработала и по запросу show variables like 'max_allowed_packet'
выводится 4 мб

А сейчас сервер не включается - значит опять вес неправильно сделала
