В настоящее время я создаю тестовую установку для приложения RADIUS, использующего FreeRADIUS V.3.xx в сочетании с MySQL. Вся установка должна быть избыточной. Все серверы работают на виртуальных машинах под управлением openSUSE 13.1.
Моя проблема в том, что я не могу найти правильную конфигурацию для резервных серверов MySQL. У кого-нибудь есть опыт в этом?
Что я делал до сих пор, так это следил за соответствующей частью официальной вики freeradius... пытался придумать варианты, используя группу, детализацию, прямое манипулирование сокетом rlm_sql_mysql... все, что я мог придумать... но безуспешно. В настоящее время он вернулся к «статусу вики».
То есть:
Я удалил ссылку на sql из .../mods-enabled/, поскольку это приводило к сбою резервных серверов даже при создании экземпляра...
Файл: .../radius.conf
Раздел: модули {...} Добавлены записи:
sql sql1{ ...#config...}
sql sql2{ ...#config...}
Раздел: instanceate {...} Добавлена запись:
redundant redundant_sql {
sql1
sql2
handled
}
А затем добавил redundant_sql в файл: .../sites-available/default (связан с сайтами с поддержкой)
Разделы: авторизация {...} и пост-аутентификация{...} (учет мне не нужен)
Вот некоторые из выводов отладки:
Создание экземпляра (и sql1, и sql2 должны быть доступны для запуска сервера RADIUS... что дерьмово, но не является текущей проблемой):

После разрушения последнего соединения с sql1 я ожидаю, что «избыточный» сработает и свяжется с sql2 ... но вместо этого RADIUS прерывается.
Я знаю, что я только ** IP и Mac, но все остальное будет правильно сброшено в любом случае, если этот проект закончит «стадию тестовой настройки».
Я был бы очень признателен за любую помощь, так как я здесь как бы в конце моей веревки.
Большое спасибо, если вы хотя бы дочитали до сюда!
