PHP-FPM и Nginx: 502 Bad Gateway

конфигурация

• Ubuntu Server 11.10 64 бит
• Amazon AWS, Ec2, размещенный в облаке
• Пример t1.micro

Прежде чем написать что-нибудь еще, я хотел бы заявить, что я проверил как nginx 502 bad gateway, так и Nginx + PHP-FPM 502 Bad Gateway , которые, к сожалению, не помогли мне в этом отношении.

• PHP и PDO: подключение к MySQL с использованием адреса IPv6
• Файлы PHP не перемещаются из / tmp
• Как программировать логин / аутентификацию пользователя?
• Push-уведомление | обязательна ли websocket?
• Запрос ОЧЕНЬ медленный (> 30 секунд) в php, но быстрый при запуске запроса в phpmyadmin

Проблема представляется довольно распространенной: неправильная конфигурация nginx или php-fpm может привести к ошибке 502 Bad Gateway , от которой я не смог избавиться. Обратите внимание, что это появляется даже тогда, когда я перехожу к своему корню домена , не указав какой-либо конкретный каталог.

Я запускаю веб-сервер Amazon EC2 с включенным портом 9000, порт 80 открыт и т. Д.

Вопрос в частности заключается в том, как я могу избавиться от этой неприятной ошибки? Или, еще лучше, как я могу получить php5-fpm чтобы на самом деле работать .

Что я покушался

В основном согласованное редактирование файлов конфигурации, в частности php-fpm.conf и nginx.conf .

я. PHP-fpm.conf

Я добавил следующее, что не очень помогло:

 ;;;;;;;;;;;;; ; Fpm Start ; ;;;;;;;;;;;;; ;pm.start_servers = 20 ;pm.min_spare_servers = 5 ;pm.max_spare_servers = 35 

Теперь, после этого, я попытался включить файлы конфигурации:

include=/etc/php5/fpm/*.conf

Который только прикрутил меня еще дальше.

Честно говоря, эта конфигурация представляет собой небольшое количество веб-сайтов, которые я посетил, но могу сказать вам, что перед этим бизнесом 502 Bad Gateway сервер работал нормально (без работы PHP. Period.).

Проблема прежде всего заключается в том, что что-то ужасно, ужасно неправильно. И теперь, когда я пытаюсь service php5-fpm restart , он зависает в том, что я догадываюсь, это бесконечный цикл или что-то еще, чего я даже не могу удалить из CTRL- C .
