Я сделал веб-сайт Wordpress, впервые размещенный локально на локальном сервере Flywheel.
Я пытаюсь полностью самостоятельно разместить его на персональном сервере (работает под управлением Ubuntu 18.04), не используя какой-либо сетевой ftp. Я не нашел в Интернете документации о том, как это сделать, только люди, пытающиеся продавать свои ftp-сервисы с готовой к использованию средой Wordpress ... Мне удалось установить некоторые вещи, и при входе в stati c IP адрес веб-сайта, он работает!
Проблема:
Через некоторое время появляется следующее сообщение: Error while trying to connect to the database и веб-сайт не работает.
Если снова запустить /etc/init.d/mysql start, веб-сайт снова заработает! 30 минут спустя, он снова ломается, показывая сообщение выше ...
Это то, что я сделал:
Я использовал Duplicator, чтобы сделать изображение веб-сайта и передал его на сервер. Я установил:
- nginx (для обратного прокси)
- php 7.2
- mysql -сервер
- mysql -client
- php7 .2- mysql и некоторые другие расширения
Мои логины wp-config.php верны
Можете ли вы мне помочь, пожалуйста ?
