Проблемы с MariaDB
Пользуюсь Vesta больше двух лет, никаких нареканий не возникало, но с сентября все стало плохо.
Причина:
Для большинства своих проектов использую сервер на DigitalOcean(хватает стандартного на 512мб)+Vesta CP и на неё уже накатываю Wordpress.
Всегда использовал стандартный конфиг.
Я так понимаю, сентября в стандартной конфигурации поменяли DB на MariaDB. Проблема в том, что почему-то резко возросло потребление RAM.
Пример.
1. Прошлая версия Vesta c MySQL
2. Один из моих новых проектов с MariaDB
Что нужно сделать, чтобы уменьшить потребление памяти?
Если ничего сделать нельзя, то как сделать так, чтобы при установке Vesta можно было выбрать mySQL а не MariaDB
Буду рад любой помощи, спасибо.

Re: Проблемы с MariaDB
Если включена опция performance_schema, то стоит отключить.
Проверка командой mysql -e 'show variables like "performance_schema"'
В my.cnf добавить performance_schema=0

ТС по руски написал Wordpress, движком используется performance_schema для оптимизации запросов.

Но вообще часть вопроса была в другом
Можно ли сделать так, чтобы по дефолту ставился mySQL а не Maria? Я понимаю, MariaDB вроде как лучше, но меня вполне устраивало то, что было раньше.
А то для каждого проекта возиться с конфигом БД – то ещё удовольствие.
Re: Проблемы с MariaDB
конфиги в части потребления памяти сервером бд у мариидб и мускула одинаковые.
мариа быстрее и безопаснее, т.к. выход обновлений безопасности на марии почти моментальный по сравнению мускулом
если хотите что из-за быстродействия сервера BD проект не страдал, так и так придется оптимизировать базу под проект. с ростом проекта растет база растут индексы. поэтому придется корректировать key_bufer_size, query_cache_size и tmp_table_size, главное помните не задирать два последних больше 128M, производительность пойдет в негатив

Постоянно падает база, раньше такого не было. Помогите как исправить.
