nginx下隐藏admin和当前域名下得index.php

//nginx.conf
server {
        listen       80;
        server_name  www.ehotel.com www.ehotel.com;
        root   "E:/phpStudy/WWW/Ehotel";
        location / {
            index  index.html index.htm index.php;
            #autoindex  on;
               if (!-e $request_filename) {
                rewrite  ^/(.*)$  /index.php?s=$1  last;
                break;
              }
              
        }
        location /admin/ {
            index  index.html index.htm index.php;
            #autoindex  on;
               if (!-e $request_filename) {

                #rewrite ^/目录/(.*)$ /目录/index.php/$1 last;
                break;
              }
              
        }
     
        
       
        location ~ \.php(.*)$ {
            fastcgi_pass   127.0.0.1:9000;
