server {
    listen      80;
    root /home/fdola.com/public_html/sub/public; # This path should point the the folder of index.php
    include /etc/nginx/conf/ddos2.conf;
    index index.php index.html index.htm;
    server_name fdola.com;

    location / {
        if ($http_host ~* "^www\.(.*)$"){
            rewrite ^(.*)$ http://%1/$1 redirect;
        }
        try_files $uri $uri/ /index.php;
    }

    location ~ \.php$ {
        try_files     $uri =404;

        fastcgi_pass  127.0.0.1:9000;
        fastcgi_index /index.php;

        include fastcgi_params;
        fastcgi_split_path_info       ^(.+\.php)(/.+)$;
        fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
    }

    location ~ /\.ht {
        deny all;
    }
}

EDIT: .htaccess is for apache only, you can delete those files
