这是整个项目的样子：

2. Django项目如何创建

2.1 首先需要在ubuntu上面安装python-pip

sudo apt-get install python3-pip

2.2 升级pip

(sudo) pip3 install –upgrade pip

2.3 安装django

sudo pip3 install Django==1.8.0

2.4 创建工程项目microblog

django-admin.py startproject microblog 此时的情况：

	│── microblog      
	│   ├── db.sqlite3      
	│   ├── manage.py      
	│   └── microblog      
	│       ├── __init__.py      
	│       ├── __pycache__      
	│       │      ├── __init__.cpython-35.pyc      
	│       ├── settings.py      
	│       ├── urls.py      
   	│       └── wsgi.py      

2.5 创建app项目blog（此命令在manage.py同级的目录处执行）

python3 manage.py startapp blog

2.6 首先在settings.py中添加自己的app名称：

	INSTALLED_APPS = (
	'django.contrib.admin',
	'django.contrib.auth',
	'django.contrib.contenttypes',
	'django.contrib.sessions',
	'django.contrib.messages',
	'django.contrib.staticfiles',
	
	'blog',
	)

新建的 app 如果不加到 INSTALL_APPS 中的话, Django 就不能自动找到app中的模板文件(app-name/templates/下的文件)和静态文件(app-name/static/中的文件)

2.7 在views.py中定义视图函数：

# coding:utf-8
# !usr/bin/env python3

from django.http import HttpResponse
from django.shortcuts import render
from django.views.decorators.csrf import csrf_exempt

# Create your views here.

# 定义了一个index()函数，第一个参数必须是 request，与网页发来的请求有关，request 变量里面包含get或post的内容，用户浏览器，系统等信息在里面
# HttpResponse，它是用来向网页返回内容的，就像Python中的 print 一样，只不过 HttpResponse 是把内容显示到网页上


def index(request):
    return render(request, 'index.html', {'title': '我是自由修改的标题'})
    # return HttpResponse(u'欢应')


# 由于使用POST要CSTF，因此要加上这个
@csrf_exempt
def user(request):
    if request.method=='POST':
        m_user = request.POST.get('user', 'default')
        m_pwd = request.POST.get('pwd', '111111')
        m_option = request.POST.get('love', 'default')
        return HttpResponse(m_user + m_pwd + m_option)
    else:
        return HttpResponse("这是get请求")

2.8 在urls.py中定义视图函数相关的url：

# coding:utf-8
# !usr/bin/env python3

from django.conf.urls import include, url
from django.contrib import admin

# 自己导入
from blog import views as blog

urlpatterns = [
    # Examples:
    # url(r'^$', 'microblog.views.home', name='home'),
    # url(r'^blog/', include('blog.urls')),


    url(r'^$', blog.index, name='default'),
    url(r'^admin/', include(admin.site.urls)),
    url(r'^index', blog.index, name='index'),
    url(r'^user', blog.user, name='user')
]

（注意需要在settings.py添加模板的路径，顺便添加静态文件位置，以及ALLOWED_HOSTS：

# 需要在DIRS中添加模板文件路径
TEMPLATES = [
    {
        'BACKEND': 'django.template.backends.django.DjangoTemplates',
        'DIRS': ['blog/templates'],
        'APP_DIRS': True,
        'OPTIONS': {
            'context_processors': [
                'django.template.context_processors.debug',
                'django.template.context_processors.request',
                'django.contrib.auth.context_processors.auth',
                'django.contrib.messages.context_processors.messages',
            ],
        },
    },
]
# 此处填写Ip(比如23.12.34.56)和对应的域名(www.baidu.com)
ALLOWED_HOSTS = ['XX.XXX.XX.X','XXX']

STATIC_URL = '/static/'

# python manage.py collectstatic
# 就会自动把所有STATICFILES_DIRS静态文件全部复制到STATIC_ROOT中
# STATIC_ROOT = os.path.join(BASE_DIR, '/home/')

# 用来存放单个App的静态文件
STATICFILES_DIRS = (
    'blog/static',
)

）

2.9 更改一下models.py文件并：

python3 manage.py makemigrations
python3 manage.py migrate

2.10 此时运行：

python3 manage.py runserver 8000
(默认在8000端口运行)

服务器部分

1.1 安装pip3：

sudo apt install python3-pip

1.2 在服务器上下载uwsgi：

sudo python3 -m pip install uwsgi

1.3 安装nginx：

sudo apt-get install nginx

1.4 在工程目录下建立myweb_uwsgi.ini文件：

|-- blog  
|   |-- __init__.py  
|   |-- __pycache__  
|   |   |-- __init__.cpython-35.pyc  
|   |   |-- views.cpython-35.pyc  
|   |-- admin.py  
|   |-- migrations  
|   |   |-- __init__.py  
|   |-- models.py  
|   |-- static  
|   |   |-- zfbcdn.js  
|   |-- templates  
|   |   |-- index.html  
|   |-- tests.py  
|   |-- views.py  
|-- db.sqlite3  
|-- manage.py  
|-- microblog  
|   |-- __init__.py  
|   |-- __pycache__  
|   |   |-- __init__.cpython-35.pyc  
|   |   |-- settings.cpython-35.pyc  
|   |   |-- urls.cpython-35.pyc  
|   |   |-- wsgi.cpython-35.pyc  
|   |-- settings.py  
|   |-- urls.py  
|   |-- wsgi.py  
|-- myweb_uwsgi.ini  

文件内容如下：

# myweb_uwsgi.ini file
[uwsgi]
# django-related settings
# django project socket port
socket = :8000
# set running directory before loading
chdir = /home/microblog
# python project's wsgi file location
module = microblog.wsgi
# enable master process
master = true
# processes that were opened
processes = 4
# file permission
chomd-socket = 664
# autoclean environments when server exits
vacuum = true
# let process run in daemonize
daemonize = /home/log/blogserver.log
# split log file by size(KB)
log-maxsize = 1000000

1.5 然后进入/etc/nginx目录下：

mylinux@VM-11-11-mylinux:/home/microblog$ cd /etc/nginx
mylinux@VM-11-11-mylinux:/etc/nginx$ ls
conf.d          koi-utf     nginx.conf    sites-available  uwsgi_params
fastcgi.conf    koi-win     proxy_params  sites-enabled    win-utf
fastcgi_params  mime.types  scgi_params   snippets
mylinux@VM-11-11-mylinux:/etc/nginx$ 

然后sudo vi nginx.conf后不更该其他内容，只在http{}内进行操作：

user www-data;
worker_processes auto;
pid /run/nginx.pid;

events {
        worker_connections 768;
        # multi_accept on;
}



http {


        server {
        listen 80 ;
# 此处填写域名，比如www.baidu.com
        server_name XX ;
        charset UTF-8 ;
        access_log /home/log/myweb_access.log ;
        error_log /home/log/myweb_error.log ;

        client_max_body_size 75M ;

        location / {
            include uwsgi_params ;
            uwsgi_pass 127.0.0.1:8000 ;
            uwsgi_read_timeout 2 ;
        }

        location /static {
            expires 30d ;
            autoindex on ;
            add_header Cache-Control private ;
            alias /home/microblog/blog/static/ ;
        }
}

        # Basic Settings
        ##

#       sendfile on;

        ##
        # Virtual Host Configs
        ##

#       include /etc/nginx/conf.d/*.conf;
#       include /etc/nginx/sites-enabled/*;
}

#mail {
#       # See sample authentication script at:
#       # http://wiki.nginx.org/ImapAuthenticateWithApachePhpScript
#
#       # auth_http localhost/auth.php;
#       # pop3_capabilities "TOP" "USER";
#       # imap_capabilities "IMAP4rev1" "UIDPLUS";
#
#       server {
#               listen     localhost:110;
#               protocol   pop3;
#               proxy      on;
#       }
#
#       server {

#               protocol   imap;
#               proxy      on;
#       }
#}

1.6 然后运行Django项目：

uwsgi –ini /home/microblog/myweb_uwsgi.ini

1.7 然后运行或重启nginx：

service nginx restart

1.8 成功
