не могу подключить мою установку laravel к установке mysql очень сложно

У меня есть установка laravel без связи с моей установкой Mysql-MariaDB, соединение требует сокета для загрузки. Можете ли вы проверить эти журналы для подсказки? .. спасибо!

Иметь Ubuntu (uname -a):

`Linux canna-r430 4.15.0-33-generic #36-Ubuntu SMP Wed Aug 15 16:00:05 UTC 2018 x86_64 x86_64 x86_64 GNU/Linux
