Hello!
NGINX собран так:
--with-rtsig_module
--with-http_stub_status_module
--without-http_charset_module
--without-http_ssi_module
--without-http_auth_basic_module
--without-http_autoindex_module
--without-http_geo_module
--with-debug
Задача только проксировать, сам контент на нескольких серверах,
там стоит "apache-mod_accel-apache".
Конфигурация такая:
===============================
server {
listen X.X.X.X:80;
server_name host1.domain.com;
access_log /opt/nginx/logs/access_log combined;
location / {
proxy_set_header X-Real-IP $remote_addr;
proxy_pass http://host1.domain.com:81/;
}
}
server {
listen X.X.X.X:80;
server_name host2.domain.com;
access_log /opt/nginx/logs/access_log combined;
location / {
proxy_set_header X-Real-IP $remote_addr;
proxy_pass http://host2.domain.com:81/;
}
}
server {
listen X.X.X.X:80 default;
access_log /opt/nginx/logs/access_log combined;
rewrite ^/redirect http://www.google.com;
error_page 404 =302 /redirect;
error_page 403 =302 /redirect;
location / {
root /var/www;
deny all;
}
}
===============================
linux, ядро: 2.4.21-37.EL (redhat el3)
Проблемма заключается в том, что если я убираю proxy,
и прописываю "root /var/www" то все ок, как только добавляю
proxy инструкции как выше описано, начинает валиться:
"worker process 1881 exited on signal 11"
Визуально это выглядить как непрогруженные элементы страницы,
картинки к примеру. клацаешь reload 20 раз постоянно разные картинки не
показывает.
Я сделал отладочный лог.

=====================================
ps
И вторая проблемма в том что если в вышеописанной конфигурации
я поднимаю:
server {
listen X.X.X.X:80 default;
access_log /opt/nginx/logs/access_log combined;
rewrite ^/redirect http://www.google.com;
error_page 404 =302 /redirect;
error_page 403 =302 /redirect;
location / {
root /var/www;
deny all;
}
}
выше виртуал хостов, у меня никогда не полчается зайти на на
host1.domain.com ни на любой другой виртуал хост, все уходит в этот
блок server. Я уверен что броузер посылает "Host:". Ну и плюс ко всему
если ставить эту струкруту ниже виртхостов то все работает.
Причем когда не используются прокси эту кострукцию оже можно ставить выше
тогда работает всё как задумано. Более того на других серверах
у меня нету слова default и такая структура стоит выше виртхостов,
и тоже все работает но там нету прокси.
Вобщем, надеюсь на помощь.
Спасибо!
