 #隐藏index.php
  location / {
     if (!-e $request_filename) {
          #一级目录
         # rewrite ^/(.*)$ /index.php/$1 last;
          #二级目录
          rewrite ^/myapp/(.*)$ /myapp/index.php/$1 last;
       } 
  }
 #pathinfo设置
    location ~ \.php($|/) {
      fastcgi_pass  127.0.0.1:9000;
      fastcgi_index index.php;
      fastcgi_split_path_info ^(.+\.php)(.*)$;
      fastcgi_param  path_info $fastcgi_path_info;
      fastcgi_param script_filename  $document_root$fastcgi_script_name;
