 *                         Ubuntu Nginx uwsgi django 初试
 * 说明：
 *     最近打算通过Python搭建一个数据收集的网站，先做一个搭建测试。
 *

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

    2 directories, 8 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 8000 default_server;
        listen [::]:8000 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 404.
            # try_files $uri $uri/ =404;
            include  uwsgi_params;
            uwsgi_pass  127.0.0.1:9091;              #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

        #error_page 404 /404.html;
    
        # redirect server error pages to the static page /50x.html
        #
        #error_page 500 502 503 504 /50x.html;
        #location = /50x.html {
        #   root /usr/share/nginx/html;
        #}
    
        # pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000
        #
        #location ~ .php$ {
        #   fastcgi_split_path_info ^(.+.php)(/.+)$;
        #   # NOTE: You should have "cgi.fix_pathinfo = 0;" in php.ini
        #
        #   # With php5-cgi alone:
        #   fastcgi_pass 127.0.0.1:9000;
        #   # 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 8000;
    #   listen somename:8080;
    #   server_name somename alias another.alias;
    #   root html;
    #   index index.html index.htm;
    #
    #   location / {
    #       try_files $uri $uri/ =404;
    #   }
    #}
    
    
    # HTTPS server
    #
    #server {
    #   listen 443;
    #   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 TLSv1.1 TLSv1.2;
    #   ssl_ciphers "HIGH:!aNULL:!MD5 or HIGH:!aNULL:!MD5:!3DES";
    #   ssl_prefer_server_ciphers on;
    #
    #   location / {
    #       try_files $uri $uri/ =404;
    #   }
    #}
    root@zengjf:/etc/nginx/sites-available# 

四、运行uwsgi命令：
    root@zengjf:/home/zengjf/website# uwsgi --socket 127.0.0.1:9091 --chdir /home/zengjf/website/mysite --wsgi-file mysite/wsgi.py --master --processes 2 --threads 2
