NOTE：不使用nginx，只使用uwsgi+django也是可以实现WEB服务的。uwsgi也可以直接处理WEB请求。
第一步先解决uwsgi与django的桥接。解决在没有nginx的情况下，如何使用uwsgi+DJANGO来实现一个简单的Web服务器。
第二步解决uwsgi与Nginx的桥接。通过nginx与uwsgi的桥接，打通nginx与django的连通，从而比较完美的实现django的部署。
环境介绍
安装uwsgi
<spanpalatino linotype new roman color:rgb>$ <spanpalatino linotype new roman color:rgb>export <spanpalatino linotype new roman color:rgb>LDFLAGS<spanpalatino linotype new roman color:rgb>=<spanpalatino linotype new roman color:rgb>"-Xlinker --no-as-needed"<spanpalatino linotype new roman color:rgb>$ pip install uwsgi </spanpalatino></spanpalatino></spanpalatino></spanpalatino></spanpalatino></spanpalatino>
测试uwsgi
# test.py
def application(env, start_response):
start_response('200 OK', [('Content-Type','text/html')])
return "Hello World"
uwsgi --http :8001 --wsgi-file test.py
配置django
NOTE：
请保证你的django项目是正常使用的。可以使用
python manage.py runserver 0.0.0.0:8002
来测试一下你的django项目是否能正常跑起来。
注意： 编写文件时需要注意语句os.environ.setdefault。比如，如果你的项目为mysite，则你的语句应该是
1 2 3 4 5 6 7 8 9 10 11 12 13 14

连接django和uwsgi，实现简单的Web服务器。
uwsgi --http :8000 --chdir /home/work/src/sites/testdjango1/testdjango/mysite --module django_wsgi
最后：
参考、解释及其它
wsgi: WSGI是一种Web服务器网关接口。它是一个Web服务器（如nginx）与应用服务器（如uWSGI服务器）通信的一种规范。
关于WSGI协议看这里：WSGI
uWSGI: http://uwsgi-docs.readthedocs.org/en/latest/index.html uWSGI是一个Web服务器，它实现了WSGI协议、uwsgi、http等协议。 Nginx中HttpUwsgiModule的作用是与uWSGI服务器进行交换。
uwsgi: uwsgi同WSGI一样是一种通信协议，而uWSGI是实现了uwsgi和WSGI两种协议的Web服务器。
uwsgi协议是一个uWSGI服务器自有的协议，它用于定义传输信息的类型（type of information），每一个uwsgi packet前4byte为传输信息类型描述，它与WSGI相比是两样东西。
关于uwsgi协议看这里：The uwsgi protocol
有了uWSGI为什么还需要nginx？
nginx具备优秀的静态内容处理能力，然后将动态内容转发给uWSGI服务器，这样可以达到很好的客户端响应。

重启Nginx服务器，以使Nginx的配置生效。
nginx -s reload
重启后检查Nginx日志是否有异常。
启动uWSGI服务器
cd /home/work/src/sites/testdjango1/testdjango/mysite uwsgi -x djangochina_socket.xml
检查日志 uwsgi.log 是否有异常发现。
访问服务
基于上面的假设你的域名是www.you.com
因此，我们访问 www.you.com，如果发现程序与 单独使用Django启动的程序一模一样时，就说明成功啦！
关闭服务的方法
将uWSGi进程杀死即可。
一些建议
uWSG配置文件的进程数，可以根据实际情况分配。不要开得太大，否则机器可能会内存耗用太高。一般来说，对于一个小社区来说，4个进程已经足够了。
一般情况下，可以编写一下 stop.sh 脚本 来关闭uWSGI。
以上就介绍了五步教你实现使用Nginx+uWSGI+Django方法部署Django程序，包括了方面的内容，希望对PHP教程有兴趣的朋友有所帮助。
