        listen       80;
        server_name  www.xxx.com xxx.com;
        access_log  /data/varlog/nginx/xxx.log  main;

        root           /data/wwwroot/web/xxx/public;
           index  index.php index.html index.htm;
        if ($http_host = xxx.com) {
            rewrite (.*) http://www.xxx.com;
        }
        location / {
         try_files $uri $uri/  /index.php?_url=$uri&$args;    
        }
    gzip on;

        error_page  404              /404.html;
        error_page   500 502 503 504  /50x.html;
        location = /50x.html {
        }

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

            fastcgi_pass   127.0.0.1:9725;
            fastcgi_split_path_info ^(.+.php)(/.+)$;
            fastcgi_index  index.php;
            fastcgi_param  SCRIPT_FILENAME  $document_root$fastcgi_script_name;
            include        /usr/local/openresty/nginx/conf/fastcgi_params;
        }

        location ~ /.ht {
           deny  all;
        }
        location ~* .(js|css|png|jpg|jpeg|gif|ico)$ {
            expires max;
