1. ngixn配置

   server {

   listen       9000;
   server_name  localhost ;
   root   "/Applications/MAMP/htdocs/xx/xx/xx/public";
   location / {
       try_files \$uri \$uri/ /index.php?\$query_string;
       index  index.html index.htm index.php;
       #autoindex  on;
   }
   location @rewrite {    
       rewrite ^/(.*)$ /index.php?_url=/$1;    
   } 
   

   }

2.报错如下:
rewrite or internal redirection cycle while internally redirecting to "/index.php",
