请问Flask开发应用nginx与uwsgi应该如何部署

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

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
│
│──── venv
│ │──── bin
│ │────include
│ │──── lib
│ │──── local
│────app.py
│
│────static
│────templates
│────flask-blog-test-uwsgi.ini
│────flask-blog-test.conf

nginx+uwsgi+python+flask给你一个参考吧
1.修改/etc/nginx/nginx.conf文件
... http { ... ## # Virtual Host Configs ## #include /etc/nginx/conf.d/*.conf; include /etc/nginx/sites-enabled/*.conf; }
默认配置基础上改了Virtual Host Configs：
include /etc/nginx/sites-enabled/*.conf;
2.创建/etc/nginx/sites-enabled/www.xxx.com.conf文件
server { listen 80; server_name www.xxx.com xxx.com; access_log /var/log/nginx/www.xxx.com.access.log; error_log /var/log/nginx/www.xxx.com.error.log; location / { include uwsgi_params; uwsgi_pass unix:///tmp/uwsgi_www.xxx.com.sock; } }
3.创建/etc/uwsgi/apps-enabled/www.xxx.com.ini文件
[uwsgi] plugins = python vhost = true chmod-socket = 666 socket = /tmp/uwsgi_www.xxx.com.sock venv = /var/www/www.xxx.com/env chdir = /var/www/www.xxx.com module = runserver callable = app
用了virtualenv：
venv = /var/www/www.xxx.com/env
这是代码部署的目录：
chdir = /var/www/www.xxx.com
4.代码的结构
代码的目录是这样的：
├── env │ ├── bin │ ├── include │ ├── lib │ └── local ├── runserver.py └── abc ├── __init__.py ├── models.py ├── static ├── templates └── views.py
代码目录里有一个runserver.py:
#coding=utf-8 from abc import app ... if __name__ == '__main__': ... app.run()
其中app是Flask对象
from flask import Flask app = Flask(__name__)
5.修改权限
sudo chmod -R 775 /var/www/www.xxx.com/ sudo chown -R www-data:www-data /var/www/www.xxx.com/
6.记得安装uwsgi-plugin-python
sudo apt-get install uwsgi-plugin-python
