Впервые мы создали Nginx и PHP-FPM. Неделю назад мы использовали Apache для обслуживания веб-страницы, но мы решили попробовать комбинацию Nginx, и перед нами стоят несколько проблем.
У нас есть виртуальная машина под управлением Ubuntu 14.04 LTS Trusty. Среди других утилит машина работает с Nginx с PHP-FPM и MySQL, и вот когда возникает проблема:
Мы пришли к выводу, что клиент может подключиться к Nginx, но Nginx при перенаправлении запроса на FPM (к которому можно получить доступ через порт 7777) не получает ответа и показывает ошибку таймаута. Мы сосредоточились на устранении неполадок связи между Nginx и FPM, но через несколько часов мы не нашли решения.
Примечание . Эта проблема повторяется на всех четырех виртуальных машинах, которые мы установили.

Что мы сделали до сих пор (эти конфигурации не могут быть отражены в вышеуказанных файлах)
proxy_read_timeout в конфигурации nginx. max_execution_time и request_terminate_timeout равным 300 (на php.ini и nginx.conf, соответственно). worker_process и worker_connections в конфигурации nginx. Listen из /var/run/php5-fpm.sock на 127.0.0.1:7777 на конфигурацию nginx и php-fpm. Мы продолжим работу над решением, и если найденный будет опубликован здесь. Благодаря!
Решено!
Кажется, проблема возникла в PHP-коде. При использовании remote_host атрибут remote_host не был установлен, и мы до сих пор не знаем, почему процедуры xdebug выполняются случайным образом в зависимости от удаленного хоста.
Примечание : когда мы использовали только Apache, эта проблема никогда не возникала. Это начало происходить при использовании Nginx + php-fpm, но неважно, наконец, проблема была решена.
Благодарю.
