使用flask开发一个应用，需要部署，可是按照网络上的一些blog总是会报各种错误，实在配置不好了，烦请大叫指教。

使用的是阿里云服务器，Ubuntu 12.04.4 LTS。

大致步骤是模仿开源中国步骤完成的，如果完全按照原来的步骤进行是可以访问的，但是如果更改成我只得代码就会报
502 Bad Gateway
我的代码是存放在Github
－－－－－下面是我修改之后的配置文件。
1. 创建/var/www/flask-blog-test/flask-blog-test.conf

server {
    listen      80;
    server_name localhost;
    charset     utf-8;
    client_max_body_size 75M;

    location /static {
        root /var/www/flask-blog-test/;
    }

    location / { try_files $uri @yourapplication; }
    location @yourapplication {
        include uwsgi_params;
        uwsgi_pass unix:/var/www/flask-blog-test/flask-blog-test.sock;
    }
}

ln -s /var/www/flask-blog-test/flask-blog-test.conf /etc/nginx/conf.d/
/etc/init.d/nginx restart

1. 创建/var/www/flask-blog-test/flask-blog-test-uwsgi.ini

[uwsgi]
#application's base folder
base = /var/www/flask-blog-test

#python module to import
app = app
module = %(app)

home = %(base)/venv
pythonpath = %(base)

#socket file's location
socket = /var/www/flask-blog-test/%n.sock

#permissions for the socket file
chmod-socket    = 666

#the variable that holds a flask application inside the module imported at line #6
callable = app

#location of log files
logto = /var/log/uwsgi/%n.log

"
sudo mkdir -p /var/log/uwsgi

3. 启动uwsgi

uwsgi --ini /var/www/flask-blog-test/flask-blog-test-uwsgi.ini

4. 文件目录是

flask-blog-test
