    listen       80;
    server_name  localhost; # change this for your server
    root /usr/share/nginx/html;
    index index.php;
    client_max_body_size 5G;

    # pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000
    location ~ \.php$ {
        if (!-e $request_filename) { rewrite ^/(.*) /index.php?_page_url=$1 last; }
        fastcgi_pass   127.0.0.1:9000;
        fastcgi_index  index.php;

    location / {
        if (!-e $request_filename) {
            rewrite ^/(.*) /index.php?_page_url=$1 last;
        }
    }

    location /files/ {
        internal;
    }

    # these locations would be hidden by .htaccess normally
    location /core/logs/ {
        deny all;
    }

    location ~* "/\.(htaccess|htpasswd)$" {
        deny    all;
        return  404;
