🎮 Балансировка нагрузки для TCP-сервисов

Проблема: необходимо распределить трафик между несколькими TCP-серверами.

Решение: в книге "Nginx Cookbook: Advanced Recipes for High-performance Load Balancing" автор показывает использование модуля stream для балансировки нагрузки на уровне транспортного слоя.

Пример кода:

stream {
    upstream mysql_read {
        server read1.example.com:3306 weight=5;
        server read2.example.com:3306;
        server 10.10.12.34:3306 backup;
    }

    server {
        listen 3306;
        proxy_pass mysql_read;
    }
}

Преимущества:

— Поддержка балансировки для TCP-сервисов.
— Гибкая настройка весов серверов.
— Резервирование серверов для повышения надёжности.
