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=/$1 last;  
    }  
}  

　　第二种方式 ，改变 .php的

location ~ .php {  
                #fastcgi_pass 127.0.0.1:9000;   
                #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 $1;  
                set $path_info $2;  
            }  
                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
