Hello.
First of all you should have PHP and Nginx up and running.

After many tests this Nginx config works fine with Kalkun 0.7.1:

server {
        listen 80;
        server_name kalkun.domain.com;

	access_log /var/log/nginx/kalkun.access.log;
	error_log /var/log/nginx/kalkun.error.log;
		
	root /var/www/localhost/htdocs/kalkun;

        client_max_body_size 10G;
        fastcgi_buffers 8 16K;
	fastcgi_buffer_size 53k;

	location / {
		index  index.php;
	}

	location ~* ^.+.(jpg|jpeg|gif|css|png|js|ico|xml)$ {
		access_log        off;
		expires           360d;
	}

	location ~ /\.ht {
		deny  all;
	}

        # pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000
        location ~ ^(.+?\.php)(/.*)?$ {
                try_files $1 = 404;

                include fastcgi_params;
                fastcgi_param SCRIPT_FILENAME $document_root$1;
                fastcgi_param PATH_INFO $2;
                fastcgi_param HTTPS on;
                fastcgi_pass 127.0.0.1:9000;
        }
}

Edit Kalkun’s file “application/config/config.php”:

$config['uri_protocol']	= "PATH_INFO";

Done!
