CentOS: Nginx в качестве frontend`а к Apache

Всё как всегда не просто, а очень просто:
Подключаем репозитарий
korp # rpm -ihv http://download.fedora.redhat.com/pub/epel/5/i386/epel-release-5-4.noarch.rpm

Устанавливаем всё необходимой для дальнейшей работы
korp # yum install nginx rpm-build redhat-rpm-config httpd-devel

Скачиваем модуль mod_rpaf для Apache:
korp # wget http://yum.cocoiti.com/CentOS/5/RPMS/SRPMS/mod_rpaf-0.6-2.src.rpm

Собираем и ставим mod_rpaf
korp # rpmbuild --rebuild mod_rpaf-0.6-2.src.rpm
korp # rpm -ihv /usr/src/redhat/RPMS/i386/mod_rpaf-0.6-2.i386.rpm

Настраиваем nginx
korp # cat /dev/null > /etc/nginx/nginx.conf
korp # nano /etc/nginx/nginx.conf

user  nginx;
worker_processes  2;
error_log  /var/log/nginx/error.log debug;
pid        /var/run/nginx.pid;

events {
worker_connections  1024;
}

http {
include       /etc/nginx/mime.types;
default_type  application/octet-stream;
log_format  main  '$remote_addr - $remote_user [$time_local] $status '
'"$request" $body_bytes_sent "$http_referer" '
'"$http_user_agent" "http_x_forwarded_for"';
access_log  /var/log/nginx/access.log  main;
sendfile        on;
tcp_nopush     on;
tcp_nodelay    on;
server {
listen       80;
server_name     _;
server_name_in_redirect  off;
access_log  /var/log/nginx/host.access.log  main;
location / {
proxy_pass         http://127.0.0.1:8080/;
proxy_redirect     off;
proxy_set_header   Host             $host;
proxy_set_header   X-Real-IP        $remote_addr;
proxy_set_header   X-Forwarded-For  $proxy_add_x_forwarded_for;
client_max_body_size       10m;
client_body_buffer_size    128k;
proxy_connect_timeout      90;
proxy_send_timeout         90;
proxy_read_timeout         90;
proxy_buffer_size          4k;
proxy_buffers              4 32k;
proxy_busy_buffers_size    64k;
proxy_temp_file_write_size 10m;
}
}
}

Настраиваем Apache
korp # nano /etc/httpd/conf/httpd.conf

Listen 127.0.0.1:8080

LoadModule rpaf_module modules/mod_rpaf-2.0.so

RPAFenable On
RPAFsethostname Off
RPAFproxy_ips 127.0.0.1 192.168.0.1
RPAFheader X-Real-IP

Запускам Apache и nginx
korp # /etc/init.d/nginx start
korp # /etc/init.d/httpd start

Добавляем в автозагрузку
korp # sudo /sbin/chkconfig nginx on
korp # sudo /sbin/chkconfig httpd on
