Ошибка MySql в Rails при развертывании в Passenger + Nginx

Ошибка MySql в Rails при развертывании в Passenger + Nginx

0

У меня есть приложение для рельсов с движком базы данных MySql. Я могу запустить приложение в режиме разработки локально на сервере (173.xxx.xxx.xxx), используя

     cd /var/www/demo


     rails s -b 0.0.0.0 -p3001

сервер начал

        => Booting Puma
        => Rails 5.0.7 application starting in development on http://0.0.0.0:3001
        => Run 'rails server -h' for more startup options
        Puma starting in single mode...
        * Version 3.11.4 (ruby 2.5.1-p57), codename: Love Song
        * Min threads: 5, max threads: 5
        * Environment: development
        * Listening on tcp://0.0.0.0:3001
        Use Ctrl-C to stop

У меня есть gem 'mysql2', '~> 0.5.1' в Gemfile. пакет успешно установлен.

database.yml

            development:
              adapter: mysql2
              host: localhost
              encoding: utf8
              reconnect: false
              database: demo_development
              pool: 5
              username: root
              password: password
              socket: /var/run/mysqld/mysqld.sock




            test:
              adapter: mysql2
              encoding: utf8
              reconnect: false
              database: demo_development
              pool: 5
              username: root
              password: password


            production:
              adapter: mysql2
              encoding: utf8
              reconnect: false
              database: demo_development
              pool: 5
              username: root
              password: password

Все работает нормально на локальном сервере (я мог получить доступ к приложению из браузера

http://173.xxx.xxx.xxx:3001/

). Приложение работает отлично через IP. Имя пользователя и пароль Mysql верны (я проверял с помощью mysql -u root -p). Я могу успешно войти в Mysql Prompt без каких-либо проблем.

Теперь я хочу развернуть приложение rails на Passenger + Nginx.

mysite.conf

server {
            listen 80;
            server_name www.mysite.com mysite.com;
            # Tell Nginx and Passenger where your app 'public' directory is
            root /var/www/demo/public;
            # Turn on Passenger
            passenger_enabled on;
            rails_env development;
            passenger_ruby /usr/local/rvm/gems/ruby-2.5.1/wrappers/ruby;


        }

Я перезапустил nginx

   sudo service nginx restart

Я получаю эту ошибку

Но очень странно, что одна и та же база кода работает нормально локально (rails s -b 0.0.0.0 -p 3001) без ошибок MySql.

    sudo systemctl status nginx

Имя пользователя и пароль Mysql верны.

При использовании ядра базы данных SQLite3 приложение отлично работает с пассажиром + nginx. Я думаю, проблема связана только с движком базы данных Mysql.

Спасибо в Advance.Any Help высоко ценится.

Я знаю, что это довольно просто, но вы вошли в систему как root и перезапустили service mysql restart DB service mysql restart ?

Я нашел временное исправление. я Создал нового пользователя в оболочке MySQL вместо использования учетной записи root по умолчанию.

  CREATE USER 'newuser'@'localhost' IDENTIFIED BY 'password';
  GRANT ALL PRIVILEGES ON * . * TO 'newuser'@'localhost';
  FLUSH PRIVILEGES;

database.yml

      development:
          adapter: mysql2
          host: localhost
          encoding: utf8
          reconnect: false
          database: demo_development
          pool: 5
          username: newuser
          password: password
          socket: /var/run/mysqld/mysqld.sock




        test:
          adapter: mysql2
          encoding: utf8
          reconnect: false
          database: demo_development
          pool: 5
          username: newuser
          password: password


        production:
          adapter: mysql2
          encoding: utf8
          reconnect: false
          database: demo_development
          pool: 5
          username: newuser
          password: password

Изменение пользователя в MySQL и имя пользователя в database.yml, наконец, устранили проблему. Тем не менее, не знаю, почему использование учетной записи root вызвало эту проблему.
