nginx配置pathinfo，简单

        location ~ \.php { # 原来有$符号，去掉
            fastcgi_pass 127.0.0.1:9000;
            fastcgi_index index.php;
            fastcgi_param PATH_INFO $fastcgi_script_name; #添加这一行
            fastcgi_param SCRIPT_FILENAME /var/www/$fastcgi_script_name;
            include fastcgi_params;
            include /etc/nginx/fastcgi_params;
        }
