virtualenv + django + gunicorn + supervisor + nginx ，nginx配置问题

[鸟类学]

搭了个博客，用的virtualenv + django + gunicorn + supervisor + nginx
没加nginx之前 一切都正常
加了之后点首页后 url显示 /mydjangoblogserver/ 找不到网页，但其他功能都正常
感觉是guincorn 和 nginx配置有问题，
尝试proxy_pass 改成127.0.0.1:8000 或0.0.0.0:8000 其他所有功能都用不了。
proxy_pass 直接改成域名会报502或404的错误，没继续查，但感觉 proxy_pass 应该和upstream对应
有朋友遇到过类似的问题么 求教。
下面是配置文件

ngnix.conf:

user root;
worker_processes  1;

events {
    worker_connections  1024;
}


http {
    include       mime.types;
    default_type  application/octet-stream;
    sendfile        on;
    keepalive_timeout  65;

    upstream mydjangoblogserver {
        server unix:/home/blog/dev/DjangoBlog/run/gunicorn.sock fail_timeout=0;
    }

    server{
        server_name www.xxx.club;
        root /home/blog/dev/DjangoBlog;
        listen 80;
        keepalive_timeout 70;
        location /collectedstatic/ {
            expires max;
            alias /home/blog/dev/DjangoBlog/;
        }

        location / {
            proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
            if (!-f $request_filename) {
                #proxy_pass http://xxx.club;
                proxy_pass http://mydjangoblogserver;
                break;
            }
        }
    }
