关于nginx前端，apache后端的问题 ： 配置报错 

我这几天做了一个前端是nginx，后端是apache，页面是可以访问了，但是没有加载css和图片，页面显示

顺便也把弄的nginx配置发下，方便大虾帮忙一下哦：

[root@dsvps2012 ~]# vim /usr/local/nginx/conf/vhost/www.giantsjerseys2012.com.conf 

log_format  www.giantsjerseys2012.com  '$remote_addr - $remote_user [$time_local] "$request" '
             '$status $body_bytes_sent "$http_referer" '
             '"$http_user_agent" $http_x_forwarded_for';
server
        {
                listen       80;
                server_name www.giantsjerseys2012.com giantsjerseys2012.com;
                index index.html index.htm index.php default.html default.htm default.php;
                root  /home/wwwroot/giantsj2012com;


                proxy_set_header  Host $host;
                proxy_set_header  X-Real-IP $remote_addr;
                proxy_set_header  X-Forwarded-For $proxy_add_x_forwarded_for;

                include .htaccess.conf;

                location / {
                                proxy_pass  http://50.115.42.143:80;
                        }
                location ~* \.(jpg|jpeg|gif|png)$
                        {
                                access_log  off;
                                expires  30d;
                        }
                location ~* \.(js|css)$
                        {
                                access_log  off;
                                expires  1d;
                        }

                location ~ .*\.(php|php5)?$
                        {
                                try_files $uri =404;
                                fastcgi_pass  unix:/tmp/php-cgi.sock;
                                fastcgi_index index.php;
                                include fcgi.conf;
                        }

                location ~ .*\.(gif|jpg|jpeg|png|bmp|swf)$
                        {
                                expires      30d;
                        }

                location ~ .*\.(js|css)?$
                        {
                                expires      12h;
                        }


                access_log  /home/wwwlogs/www.giantsjerseys2012.com.log  www.giantsjerseys2012.com;


        }

这个是在/usr/local/nginx/conf/vhost/www.giantsjerseys2012.com.conf添加的。。
不是在/usr/local/nginx/conf/nginx.conf添加的,因为我的vps要弄多个网站。。
希望大神帮忙解决一下哦。。谢谢了。。
