最好的时光，是自己依然有勇气面对生命中任何成功与失败!
总结：
- ngnix:80端口开启，前面我们先发起一个http请求；直接访问的根http://192.168.0.101/api/post/2，相当于根本就没有代理；这个时候 ngnix 为项目提供静态内容，api被替换掉，服务往8000端口上uWSGI，相当于/api/post/2相当于访问/post/2；
- django 相当于一个程序，没有server;
- 讲 前后端 部署 流程 后30 ；

项目 部署
1. Django打包
打包 只打python 文件；
构建setup.py文件
from distutils.core import setup
import glob
setup(name='Distutils',
version='1.0',
description='blog project',
author='wayne',
author_email='[email protected]',
url='https://magedu.com',
packages=['blog', 'post', 'user','user.templatetags'],
py_modules=['manage'],
data_files=glob.glob('templates/*.html')+['requirements'] + glob.glob('static/*')
)
#应用程序的根目录下打包（打包只针对py文件，对 html 文件无效， html要写路径）

访问成功
使用 http://192.168.0.101:8000/post?page=2&size=2 成功返回数据，说明Django应用成功;
至此，Django应用部署完成。Django带了个开发用Web Server，生成环境不用，需要借助其它Server。
注意：ALLOWED_HOSTS = ["*"] 这是所有都可以访问，生产环境应指定具体可以访问的IP，而不是所有。
2. WSGI
Web Server Gateway Interface，是Python中定义的Web Server与应用程序的接口定义。
应用程序有WSGI 的 Django框架负责，WSGI Server谁来做？
1. uWSGI （ uWSGI server服务开启， Django自带的server没开启，blog就是一个程序；
- http
3. uWSGI 项目
uW SGI是一个C语言的项目， 提供一个WEB服务器， 它支持WSGI协议， 可以和Python的WSGI应用程序通信。
的高薪职
官方文档https://uwsgi-docs.readthedocs.io/en/latest/
uW SGI可以直接启动HTTP服务， 接收HTTP请求， 并调用Django应用。
安装
(blog366) [dell@Centos7 djangoweb]$ conda install uwsgi
4. uWSGI + Django部署
在Django项目根目录下，运行 $ uwsgi --http :8000 --wsgi-file blog/wsgi.py --stats :8001 --stats-http ，使用下面的链接测试
http://192.168.0.101:8000/post/2
(blog366) [dell@Centos7 djangoweb]$ uwsgi --http:8000 --wsgi-file blog/wsgi.py

stats能够显示服务器状态值。--stats-http选项可以使用http访问这个值。
安装uwsgitop获取这个stat值。注意使用这个命令不要使用--stats-http选项。
5. Nginx uwsgi 部署
Nginx (发音同"engine x") 是一个高性能的HTTP和反向代理服务器，也是一个IMAP/POP3/SMTP服务器。Nginx的特点是占有内存少，并发能力强。中国大陆使用nginx网站用户有：百度、京东、新浪、网易、腾讯、淘宝等。
Nginx的优势
1.支持高并发连接
由于apache采用的是select网络I/O模型，Ngnix在处理大量连续高并发访问时效率要比Apache高很多。可通过top命令可以查看系统负载和CPU使用率2.内存消耗少
在服务器3W并发连接下，开启10个Nginx进程消耗150MB内存(15MB10)，开启64个php-cgi进程消耗128MB内存(20MB64)，共消耗不到2GB内存。可以使用压力测试工具webbench对Nginx进行压力测试。
3.成本低廉
购买F5 BIG-IP、NetScaler等负载均衡交换机需要几十万RMB，而开源Nginx替代这些商业设备。
4.支持热部署
能够在不间断服务的情况下、对软件版本进行升级
5.配置简单
6.其他优势
支持rewrite重写规则，能够根据域名、URL的不同、将HTTP请求分发到不同的后端服务器群组；内置的健康检查功能；节省带宽，支持GZIP压缩，可以添加浏览器本地缓存的Header头。
5.1 Ngnix 编译安装
Ngnix应该在低权限用户下跑的；

5.4 基于socket 的uWSGI+ngnix高性能模式
这是 基于http协议（访问量不高没什么问题）；webserver访问压力大 uWSGI可以修改为

5.5 部署博客前端系统
1. React 项目打包
blog 脚手架
# npm安装依赖
$ npm install rimraf --save-dev 或者 $ yarn add rimraf --dev
rimraf 递归删除文件，rm -rf
$ yarn run build # 打包
yarn run v1.22.4
$ rimraf dist && webpack -p --config webpack.config.prod.js # 加载 package.json 文件中的 built

2. 部署博客前端系统
新建assets文件夹，将app-*.js 移动到assets中
将编译好的前端项目文件index.htm与assets文件夹复制到 /usr/local/nginx/html ；
刷新首页，一切从此开始。
192.168.0.101
重新装载nginx配置文件，成功运行。
至此，前后端分离的开发、动静分离的部署的博客项目大功告成。

3.MVC设计模式
Controller控制器：处理输入： 负责接收用户请求， 调用Model完成数据， 调用view完成对用户的响应
Model模型：负责业务数据的处理
View视图：负责用户的交互界面
6. Django框架简介
在Django框架中，也是遵循MVC框架的。只不过名称有点不一样，在Django中，这种框架名叫 MVT，即模型M，视图V和模版T。
同样可以通过注册案例来理解，其思想是和MVC相同的：
Model层
表示应用程序核心（比如 ORM 建立对象关系映射，提供数据库操作）Template层
负责数据的可视化，使用HTML、CSS等构成模板，将数据应用到模板中，并返回给浏览器。View层
显示数据 ：Django完成URL映射后，把请求交给view层的视图函数处理，调用Model层完成数据，如有必要调用Template层
响应客户端，如果不需要，直接返回数据。
