It indicates that django is successfully installed.

3. Create a django Project

[Root @ LinuxOT-Test-02 nginx] # mkdir www
[Root @ LinuxOT-Test-02 nginx] # cd www
[Root @ LinuxOT-Test-02 www] # django-admin startproject mysite
[Root @ LinuxOT-Test-02 www] # tree mysite
/Mysite/
── Manage. py
── Mysite
── _ Init _. py
── Settings. py
── Urls. py
── Wsgi. py1
Directory, 5 files

Dj17] # wget
Http://projects.unbit.it/downloads/uwsgi-2.0.11.2.tar.gz

Support for Python/wsgi.

Install uwsgi Module

[Root @ LinuxOT-Test-02 mysite] # pip install uwsgi

5. Associate django with nginx

Vim/etc/nginx/conf. d/default. conf
Server {
Listen 80 default_server;
Server_name _;
Location /{
Include uwsgi_params;
Uwsgi_pass 127.0.0.1: 9090;
}
}
[Root @ LinuxOT-Test-02] # service nginx restart
Stop nginx: [OK]
Starting nginx: [OK]
[Root @ LinuxOT-Test-02 mysite] # uwsgi-s 127.0.0.1: 9090-w demo

Start the project

Access the nginx address.
