2012/07/23 15:06:53 [error] 2908#0: *247 recv() failed (104: Connection reset by peer) while reading response header from upstream, client: 81.255.98.253, server: www.acmslt.fr, request: "GET /category/culte/conferences/ HTTP/1.1", upstream: "fastcgi://127.0.0.1:9000", host: "acmslt.fr", referrer: "http://www.google.fr/url?sa=t&rct=j&q=mosqu%C3%A9e%20de%20savigny%20le%20temple%2077&source=web&cd=2&ved=0CFsQjBAwAQ&url=http%3A%2F%2Facmslt.fr%2Fcategory%2Fculte%2Fconferences%2F&ei=OzANUOj0HYrG0QXusf2xCg&usg=AFQjCNHxw6lN8eBnkEOYDh5ONmutLiATHA"
~
here is the nginx.conf



user www-data;
worker_processes 4;
events {
worker_connections 1024;
}

http {
include mime.types;
default_type application/octet-stream;

# Hide the Nginx version number
server_tokens off;

# Tweeks
sendfile on;
tcp_nodelay off;
tcp_nopush on;
keepalive_timeout 5;
client_body_timeout 10;
client_header_timeout 10;
send_timeout 10;
client_max_body_size 8M;

set_real_ip_from 127.0.0.1;
real_ip_header X-Forwarded-For;

gzip on;
gzip_disable "MSIE [1-6].(?!.*SV1)";
gzip_vary on;
gzip_comp_level 3;
gzip_proxied any;
gzip_buffers 16 8k;

include /etc/nginx/conf.d/*.conf;
include /etc/nginx/sites-enabled/*;
}


the website conf in the site available

server {
listen 8080;
server_name www.acmslt.fr acmslt.fr;
location / {
root /var/www/wordpress;
index index.php index.html index.htm;
# Rewrite rules
if (!-e $request_filename) {
rewrite ^(.+)$ /index.php?q=$1 last;
}
# Security
# include global/security.conf;
# W3 Total Cache
include global/wordpress-w3-total-cache.conf;
# PHP-FPM
include global/php-fpm.conf;
}
}

then the global/php-fpm.conf

# PHP scripts -> PHP-FPM server listening on 127.0.0.1:9000
location ~ \.php$ {
fastcgi_pass 127.0.0.1:9000;
fastcgi_index index.php;
include fastcgi_params;
fastcgi_connect_timeout 60;
fastcgi_send_timeout 180;
fastcgi_read_timeout 600;
fastcgi_temp_file_write_size 1M;
fastcgi_intercept_errors on;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
}

the php-fpm www.conf

[www]
user = www-data
group = www-data
listen = 127.0.0.1:9000
pm = dynamic
pm.max_children = 5
pm.start_servers = 2
pm.min_spare_servers = 1
pm.max_spare_servers = 3
chdir = /
