Я запускаю многосайтовый WordPress на amazon micro ec2 с suexec, Apache и php CGi на Ubuntu 12.04. Однако у меня было много ошибок Internal server 500, и я нахожусь в процессе отладки, чтобы найти решение. . Я разместил свои журналы ошибок ниже

на основании логов можно определить, в чем может быть причина этого? Думая, что это может быть микро-экземпляр, я думаю о модернизации до маленького.
Любая помощь будет принята с благодарностью.

Я обновился с экземпляра Miro до экземпляра Small, который, похоже, решил проблему, не более 500 ошибок.
Похоже, что у экземпляра Miro недостаточно памяти для эффективной работы WordPress Multi-Site на постоянной основе.
Если вам хочется иметь сверхмедленный сервер, вы можете добавить еще один EBS и использовать его в качестве свопа.
В противном случае вы можете попробовать уменьшить лимит памяти php (он установлен в php.ini), удалив неиспользуемые расширения php или перейдя на что-то более легкое, например nginx + php-fpm.
