tp3.2.3 解决http://lx.com/后必须加index.php才能访问的问题，配置文件中忘了加index index.php index.html 等默认文件

server {
                listen       80;
                server_name  lx.com;
                root    "D:\phpstudy\PHPTutorial\WWW\liuxue";

               location / {
                    index  index.php index.html index.htm;
                    if (!-e $request_filename) {
                        rewrite  ^(.*)$  /index.php?s=$1  last;
                        break;
                    }
                }

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

                location ~ \.php(.*)$  {
                    fastcgi_pass   127.0.0.1:9000;
                    fastcgi_index  index.php;
