nginx下开启pathinfo模式

　　第一种方式是通过重写url来实现pathinfo模式：　　　

1 location / {  
2     if (!-e $request_filename){  
3         rewrite ^/(.*)$ /index.php?s=/$1 last;  
4     }  
5 }

　　第二种方式，改变 .php的

 1 location ~ .php {  
 2                 #fastcgi_pass 127.0.0.1:9000;   
 3                 #fastcgi_pass unix:/dev/shm/php-cgi.sock;   
 4                 fastcgi_pass  unix:/tmp/php-cgi.sock;  
 5                 fastcgi_index index.php;  
 6                 include fastcgi.conf;  
 7                 set $real_script_name $fastcgi_script_name;  
 8                 if ($fastcgi_script_name ~ "^(.+?.php)(/.+)$") {  
 9                 set $real_script_name $1;  
10                 set $path_info $2;  
11             }  
12                 fastcgi_param SCRIPT_FILENAME $document_root$real_script_name;  
13                 fastcgi_param SCRIPT_NAME $real_script_name;  
14                 fastcgi_param PATH_INFO $path_info;  
15             }

　　第二种方案没测试通过
