二、Django目录结构：

    zengjf@zengjf:~/website$ pwd

    /home/zengjf/website

    zengjf@zengjf:~/website$ tree

    .

    └── mysite

        ├── manage.py

        └── mysite

            ├── __init__.py

            ├── __init__.pyc

            ├── settings.py

            ├── settings.pyc

            ├── urls.py

            ├── urls.pyc

            └── wsgi.py

     directories,  files

    zengjf@zengjf:~/website$

三、nginx配置：

    root@zengjf:/etc/nginx/sites-available# pwd

    /etc/nginx/sites-available

    root@zengjf:/etc/nginx/sites-available# cat default

    # You may add here your

    # server {

    #   ...

    # }

    # statements for each of your virtual hosts to this file

    ##

    # You should look at the following URL's in order to grasp a solid understanding

    # of Nginx configuration files in order to fully unleash the power of Nginx.

    # http://wiki.nginx.org/Pitfalls

    # http://wiki.nginx.org/QuickStart

    # http://wiki.nginx.org/Configuration

    #

    # Generally, you will want to move this file somewhere, and start with a clean

    # file but keep this around for reference. Or just disable in sites-enabled.

    #

    # Please see /usr/share/doc/nginx-doc/examples/ for more detailed examples.

    ##

    server {

        listen  default_server;

        listen [::]: default_server ipv6only=on;

        root /home/zengjf/website/mysite;

        index index.html index.htm;

        # Make site accessible from http://localhost/

        server_name localhost;

        location / {

            # First attempt to serve request as file, then

            # as directory, then fall back to displaying a .

            # try_files $uri $uri/ =;

            include  uwsgi_params;

            uwsgi_pass  127.0.0.1:;              #必须和uwsgi中的设置一致

            # Uncomment to enable naxsi on this location

            # include /etc/nginx/naxsi.rules

        }

        # Only for nginx-naxsi used with nginx-naxsi-ui : process denied requests

        #location /RequestDenied {

        #   proxy_pass http://127.0.0.1:8080;

        #}

        #error_page  /.html;

        # redirect server error pages to the static page /50x.html

        #

        #error_page     /50x.html;

        #location = /50x.html {

        #   root /usr/share/nginx/html;

        #}

        # pass the PHP scripts to FastCGI server listening on 127.0.0.1:

        #

        #location ~ \.php$ {

        #   fastcgi_split_path_info ^(.+\.php)(/.+)$;

        #   # NOTE: You should have "cgi.fix_pathinfo = 0;" in php.ini

        #

        #   # With php5-cgi alone:

        #   fastcgi_pass 127.0.0.1:;

        #   # With php5-fpm:

        #   fastcgi_pass unix:/var/run/php5-fpm.sock;

        #   fastcgi_index index.php;

        #   include fastcgi_params;

        #}

        # deny access to .htaccess files, if Apache's document root

        # concurs with nginx's one

        #

        #location ~ /\.ht {

        #   deny all;

        #}

    }

    # another virtual host using mix of IP-, name-, and port-based configuration

    #

    #server {

    #   listen ;

    #   listen somename:;

    #   server_name somename alias another.alias;

    #   root html;

    #   index index.html index.htm;

    #

    #   location / {

    #       try_files $uri $uri/ =;

    #   }

    #}

    # HTTPS server

    #

    #server {

    #   listen ;

    #   server_name localhost;

    #

    #   root html;

    #   index index.html index.htm;

    #

    #   ssl on;

    #   ssl_certificate cert.pem;

    #   ssl_certificate_key cert.key;

    #

    #   ssl_session_timeout 5m;

    #

    #   ssl_protocols SSLv3 TLSv1 TLSv1. TLSv1.;

    #   ssl_ciphers "HIGH:!aNULL:!MD5 or HIGH:!aNULL:!MD5:!3DES";

    #   ssl_prefer_server_ciphers on;

    #

    #   location / {

    #       try_files $uri $uri/ =;

    #   }

    #}

    root@zengjf:/etc/nginx/sites-available# 

四、运行uwsgi命令：

    root@zengjf:/home/zengjf/website# uwsgi --socket 127.0.0.1: --chdir /home/zengjf/website/mysite --wsgi-file mysite/wsgi.py --master --processes  --threads
