nginx下开启pathinfo模式

　　第一种方式是通过重写url来实现pathinfo模式：　　　

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

　　第二种方式 ，改变 \.php的

 location ~ \.php {
                 #fastcgi_pass 127.0.0.1:;
                 #fastcgi_pass unix:/dev/shm/php-cgi.sock;
                 fastcgi_pass  unix:/tmp/php-cgi.sock;
                 fastcgi_index index.php;
                 include fastcgi.conf;
                 set $real_script_name $fastcgi_script_name;
                 if ($fastcgi_script_name ~ "^(.+?\.php)(/.+)$") {
                 set $real_script_name $;
                 set $path_info $;
             }
                 fastcgi_param SCRIPT_FILENAME $document_root$real_script_name;
                 fastcgi_param SCRIPT_NAME $real_script_name;
                 fastcgi_param PATH_INFO $path_info;
             }  

　　第二种方案没测试通过
