«Безумие: делать одно и то же снова и снова и ожидать разных результатов». - Альберт Эйнштейн
У меня есть встроенная коробка vagrant + chef (w/chef-zero Berkshelf), которая запускает множество программ, включая zend-server-php, mongos и erlang. Я использую популярные поваренные книги, управляемые с помощью Berkshelf, и простую коробку CentOS 6 (хранящуюся на моем локальном Mac). Запуск этого ящика в первый раз (после vagrant destroy) обычно требует нескольких попыток. vagrant up завершится ошибкой в одной из перечисленных выше программ, и мне придется запускать vagrant provision снова и снова (иногда до 6 раз), чтобы пройти всю сборку без ошибок. Однако в редких случаях звезды сойдутся, и все заработает с первой попытки.
Ошибки, которые я вижу, часто явно являются ошибками тайм-аута (хотя и не всегда). Обычно я использую это при довольно слабом сетевом соединении в офисе (‹20 Мбит/с), что может объяснить, почему сбои происходят при самых больших загрузках.
Итак, вот мой вопрос: во-первых, есть ли какая-то другая переменная, помимо сетевого подключения, которая могла бы объяснить, почему мне пришлось бы vagrant provision несколько раз? Если да, то как я могу проверить и вылечить его? Во-вторых, есть ли способ заставить бродягу продолжать подготовку до тех пор, пока он не сделает это успешно? Я не нашел документированного флага/настройки для этого, но похоже, что он может быть...
Спасибо за вашу помощь.
ОБНОВЛЕНИЕ:
Вот пример сбоя zend-server-php-5.4:
==> mongos-zend: Running triggers before provision...
the ffi-yajl and yajl-ruby gems have incompatible C libyajl libs and should not be loaded in the same Ruby VM
falling back to ffi which might work (or might not, no promises)
