------解决方案--------------------
codeigniter在nginx下配置
应该也适用 thinkphp，你对比一下

server {
       listen  80;
       server_name     www.phpno.com;
       root /home/www/www_phpno_com/admin_wwwroot;
       access_log off;
       error_page 404  /404.html;
       location /404.html {
               root /home/www/www_phpno_com/admin_wwwroot;
