I got these two from the Wiki installation section... I will not use  
anymore and I have changed the Wiki page...

The first option worked.

My running config:

user  www-data www-data;
worker_processes  5;
worker_rlimit_core   100m;
working_directory /usr/local/nginx/;


error_log  /var/log/nginx/warn_error.log warn;
error_log  /var/log/nginx/error.log;

events {
     worker_connections  512;
}

http {
     include       /etc/nginx/mime.types;
     default_type  application/octet-stream;
     sendfile        on;
     #tcp_nopush     on;
     #keepalive_timeout  0;
     keepalive_timeout  15;
	reset_timedout_connection  on;
     tcp_nodelay        on;
	server_names_hash_bucket_size 64;

	upstream apache {
         server 192.168.3.189:80;
     }

     gzip on;
     gzip_min_length  1100;
     gzip_buffers     4 8k;
     gzip_types       text/plain;

     include         /etc/nginx/vhosts/*.conf;
}

I'm not sure how it works and how to use it. I have read man pages  
and configured my system to dump into specific subdirectory. I will  
return if I find anything.
