Расширение mysqli не найдено

[LemoneZ]

Установил lamp-server, после phpmyadmin и выдаёт вот эту ошибку. Знаю, что такой вопрос уже задавали, но ничего не помогло.

Команда php -m | grep mysqli ничего не выдала. Это означает, что mysqli необходимо как-то подключить / установить?

Это означает, что mysqli необходимо как-то подключить / установить?

В php.ini выполнили подключение расширения mysqli?:

Код: [Выделить]

extension=mysqli.soПосле чего не забудьте перезагрузить сервис Apache.

[LemoneZ]

archuser, прописал extension=mysqli.so в конце файла /etc/php/7.0/apache2/php.ini, перезапустил сервер (sudo service apache2 reload / restart), но ошибка не исчезла.

[archuser]

LemoneZ, symon.2014 скорее всего прав. Тогда установите пакет:

Код: [Выделить]

sudo apt-get install php7.0-mysql

[LemoneZ]

archuser, как ни странно, но php7.0-mysql уже установлен. о_О

[archuser]

LemoneZ, покажите содержимое /var/log/apache2/error.log

LemoneZ, мдась, гадание на кофейной гуще продолжается
