luffy项目
pip换源
1.python中下载第三方模块：
pip3 install django -i 源地址
2.永久换源
pip3 install django # 就会取配好的国内镜像下载
2.1文件管理器文件路径地址栏敲：%APPDATA% 回车，快速进入 C:\Users\电脑用户\AppData\Roaming 文件夹中
2.2新建 pip 文件夹并在文件夹中新建 pip.ini 配置文件
2.3给 pip.ini 配置文件新增内容
[global]
index-url = https://mirrors.aliyun.com/pypi/simple
[install]
use-mirrors =true
mirrors =https://mirrors.aliyun.com/pypi/simple
trusted-host =mirrors.aliyun.com
虚拟环境搭建
1.装两个模块
pip3 install virtualenv
pip3 install virtualenvwrapper-win # win装这个，linux和mac装virtualenvwrapper
-查看安装的模块
pip3 list
2.配置环境变量
2.1控制面板 => 系统和安全 => 系统 => 高级系统设置 => 环境变量 => 系统变量 => 点击新建 => 填入变量名与值
-变量名：WORKON_HOME 变量值：自定义存放虚拟环境的绝对路径
eg: WORKON_HOME: D:\Virtualenvs
2.2同步配置信息：bat只是win的批处理文件linux和mac的后缀为.sh
去向Python3的安装目录 => Scripts文件夹 => virtualenvwrapper.bat => 双击
3.使用虚拟环境(注意装的是哪个解释器)
3.1创建虚拟环境到配置的WORKON_HOME路径下
-选取默认Python环境创建虚拟环境：
mkvirtualenv 虚拟环境名称
-基于某Python环境创建虚拟环境(并进入)：
mkvirtualenv -p python3.8 虚拟环境名称
-查看已有的虚拟环境
workon
-使用某个虚拟环境
workon 虚拟环境名称
-进入|退出 虚拟环境的Python环境
python | exit()
-为虚拟环境安装模块
pip或pip3 install 模块名
-退出当前虚拟环境
deactivate
-删除虚拟环境(删除当前虚拟环境要先退出)
rmvirtualenv 虚拟环境名称
- 使用pycharm创建虚拟环境
luffy后台创建目录调整
1.创建项目，需要选择虚拟环境创建
# 再使用虚拟环境创建路飞项目前，一定要先安装django，否则会以最先django创建
2.调整路飞后端项目的目录
luffyapi
├── logs/ # 项目运行时/开发时日志目录 - 包
├── manage.py # 脚本文件
├── luffyapi/ # 项目主应用，开发时的代码保存 - 包
├── apps/ # 开发者的代码保存目录，以模块[子应用]为目录保存 - 包
├── libs/ # 第三方类库的保存目录[第三方组件、模块] - 包
├── settings/ # 配置目录 - 包
├── dev.py # 项目开发时的本地配置
└── prod.py # 项目上线时的运行配置
├── urls.py # 总路由
└── utils/ # 多个模块[子应用]的公共函数类库[自己开发的组件]
└── scripts/ # 保存项目运营时的脚本文件 - 文件夹
3.要运行，修改配置
-manage.py第9行
os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'luffy_api.settings.dev')
-wsgi.py的第14行
os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'luffy_api.settings.prod')
4.创建app时，要进入到apps文件夹下执行
python ../../manage.py startapp home
5.注册app，要导入包，都要从环境变量开始导起
-settings/dev.py 加入
import sys
import os
BASE_DIR = Path(__file__).resolve().parent.parent #小luffy_api
# 把小luffy_api和apps路径都加入到环境变量。以后直接从这俩路径下导起即可
sys.path.append(str(BASE_DIR))
sys.path.append(os.path.join(BASE_DIR,'apps'))
'配置文件修改完后，要注册app，直接写app名字即可'
后台配置之封装logger
1.日志配置(配置在配置文件中)
LOGGING = {
'version': 1,
'disable_existing_loggers': False,
'formatters': {
'verbose': {
'format': '%(levelname)s %(asctime)s %(module)s %(lineno)d %(message)s'
},
'simple': {
'format': '%(levelname)s %(module)s %(lineno)d %(message)s'
},
},
'filters': {
'require_debug_true': {
'()': 'django.utils.log.RequireDebugTrue',
},
},
'handlers': {
'console': {
# 实际开发建议使用WARNING
'level': 'DEBUG',
'filters': ['require_debug_true'],
'class': 'logging.StreamHandler',
'formatter': 'simple'
},
'file': {
# 实际开发建议使用ERROR
'level': 'INFO',
'class': 'logging.handlers.RotatingFileHandler',
# 日志位置,日志文件名,日志保存目录必须手动创建，注：这里的文件路径要注意BASE_DIR代表的是小luffyapi
'filename': os.path.join(os.path.dirname(BASE_DIR), "logs", "luffy.log"),
# 日志文件的最大值,这里我们设置300M
'maxBytes': 300 * 1024 * 1024,
# 日志文件的数量,设置最大日志数量为10
'backupCount': 10,
# 日志格式:详细格式
'formatter': 'verbose',
# 文件内容编码
'encoding': 'utf-8'
},
},
# 日志对象
'loggers': {
'django': {
'handlers': ['console', 'file'],
'propagate': True, # 是否让日志信息继续冒泡给其他的日志处理系统
},
}
}
2.在utils中新建logger.py
import logging
# 通过配置中的名字拿到logger对象，只需要导入直接使用对象写日志
logger = logging.getLogger('django')
'之后在需要使用的地方导入logger'
后台配置之封装全局异常
1.处理全局异常，新建一个exceptions.py，在文件中写个函数
from rest_framework.views import exception_handler as drf_exception_handler
from rest_framework.response import Response
from utils.logger import logger
def exception_handler(exc, context):
request = context.get('request')
# 程序出异常都要记录在日志中:请求地址、请求方式、请求时间、请求那个视图函数、用户id
try:
user_id = request.user.pk
if not user_id:
# 如果没有获取名字则默认为匿名用户
user_id = '匿名用户'
except:
user_id = '匿名用户'
# 获取视图函数
view = context.get('view')
logger.error(
f'用户:{user_id}使用:{request.method}请求，请求地址:{request.get_full_path()}，视图函数:{str(view)}，出错了，错误是:{str(exc)}')
'''
res如果是有值为Response的对象，说明是drf的异常
res如果是为None，说明是drf的异常
'''
res = drf_exception_handler(exc, context)
if res: # drf异常，错误信息是从detail中获取，如果没有则是后面的字符串
res = Response(data={'code': 999, 'msg': res.data.get('detail', '服务器出错，请联系管理员')})
else: # django异常，错误信息是将exc异常对象转成字符串
res = Response(data={'code': 888, 'msg': str(exc)})
return res
2.在配置文件中配置，出了异常就会执行函数
REST_FRAMEWORK = {
# 只要出异常，就会执行exception_handler
'EXCEPTION_HANDLER': 'utils.exceptions.exception_handler',
}
后台配置之二次封装response
1.封装一个Response类，自己写返回的code和msg字段
2.utils/response.py
from rest_framework.response import Response
class APIResponse(Response):
def __init__(self, code=100, msg='成功', status=None, headers=None, **kwargs):
data = {'code': code, 'msg': msg}
if kwargs:
data.update(kwargs)
# 调用父类的__init__来完成
super().__init__(data=data, status=status, headers=headers)
'在视图类中导入即可使用'
3.使用APIResponse返回给前端的格式为
return APIResponse(token='asfdasfd',status=201,code=101)
return APIResponse(status=200, result={'id': 1, 'name': '西游记', 'price': 10})
数据库配置
1.直接使用root用户作为项目的数据库用户，权限太高了，一般在公司中，会给项目单独建立用户，这个用户只对该库权限
2.在mysql中创建一个用户luffy_api，给用户授予luffy库的所有权限
-使用navicate客户端创建数据库
-查看有哪些用户
select user,host from mysql.user;
2.1创建一个luffy_api用户
-授权命令
grant 权限(create, update) on 库.表 to '账号'@'host' identified by '密码'
-把luffy库下所有表的权限都授予luffy_api这个用户，允许远程链接
grant all privileges on luffy.* to 'luffy_api'@'%' identified by '123';
-把luffy库下所有表的权限都授予luffy_api这个用户，允许本地链接
grant all privileges on luffy.* to 'luffy_api'@'localhost' identified by '123';
-以luffy_api用户登录，只能看到luffy库
3.在配置文件中配置好mysql数据
user = os.environ.get('USER', 'luffy_api')
pwd = os.environ.get('PWD', '123')
# 防止源代码泄露，被人获取数据库用户名、密码
DATABASES = {
'default': {
'ENGINE': 'django.db.backends.mysql',
'NAME': 'luffy',
'USER': user,
'PASSWORD': pwd,
'HOST': '127.0.0.1',
'PORT': 3306
}
}
'django默认使用mysqlDB操作mysql，只需要装mysqlclient模块即可'
3.1mysql的utf8编码与utf8mb4编码的区别
-utf8:一个字符，占两个字节
-utf8mb4:一个字符，占4个字节
'1字节(byte)等于8个比特位'
User模块User表配置，开放media访问
1.配置好mysql了，项目的用户表是会用Auth的User表，在原有字段的基础上扩写字段
2.user/models.py
from django.contrib.auth.models import AbstractUser
class UserInfo(AbstractUser):
mobile = models.CharField(max_length=11, unique=True)
# ImageField继承了CharField，使用时需要pillow包的支持
icon = models.ImageField(upload_to='icon', default='icon/default.png')
class Meta:
# 指定表名
db_table = 'luffy_user'
# 在后台管理显示的名字
verbose_name = '用户表'
verbose_name_plural = verbose_name
def __str__(self):
# 打印对象时打印用户名
return self.username
3.在配置文件中配置
# 用户表的配置
AUTH_USER_MODEL = 'user.UserInfo'
开放media访问
1.在配置文件中配置
MEDIA_URL = '/media/'
# 以后提交的文件都会保存在media文件夹下
MEDIA_ROOT = os.path.join(BASE_DIR, 'media')
2.在路由中加入
from django.views.static import serve
from django.conf import settings
urlpatterns = [
# 开启media访问
path('media/<path:path>', serve, {'document_root': settings.MEDIA_ROOT}),
]
前台项目创建和配置
创建前端
1.创建项目，删除无用的代码或文件
2.安装axios
2.1输入命令行安装
cnpm install axios
2.2配置在main.js中
import axios from 'axios'
// 将axios配置好后，在任意组件中都可以使用
Vue.prototype.$axios = axios
2.3使用
this.$axios.get()
使用elementui
1.vue2要使用elementui
cnpm i element-ui -S
// vue3使用element-plus
2.配置在main.js中
import ElementUI from 'element-ui';
import 'element-ui/lib/theme-chalk/index.css';
// 配置elementui
Vue.use(ElementUI);
3.使用方法
在任意组件中复制粘贴(template，script，style)
vue-cookies
1.安装
cnpm install vue-cookies -S
2.配置在main.js中
import cookies from 'vue-cookies'
// 配置cookies
Vue.prototype.$cookies = cookies
3.使用
this.$cookies.set()
bootstrap，jquery
1.安装
cnpm install jquery -S
cnpm install bootstrap@3 -S
2.配置在main.js中
// bootstrap配置
import 'bootstrap'
import 'bootstrap/dist/css/bootstrap.min.css'
3.vue.config.js配置
const webpack = require("webpack");
module.exports = {
configureWebpack: {
plugins: [
new webpack.ProvidePlugin({
$: "jquery",
jQuery: "jquery",
"window.jQuery": "jquery",
"window.$": "jquery",
Popper: ["popper.js", "default"]
})
]
}
};
前台全局样式和js配置
- css/global.css
/* 声明全局样式和项目的初始化样式 */
body, h1, h2, h3, h4, h5, h6, p, table, tr, td, ul, li, a, form, input, select, option, textarea {
margin: 0;
padding: 0;
font-size: 15px;
}
a {
text-decoration: none;
color: #333;
}
ul {
list-style: none;
}
table {
border-collapse: collapse; /* 合并边框 */
}
- main.js
// 去掉所有标签样式
import '@/assets/css/global.css'
全局配置js
1.js/settings.js
export default {
BASE_URL: 'http://127.0.0.1:8000/'
}
2.main.js
import settings from '@/assets/js/settings'
// 全局配置
Vue.prototype.$settings = settings
3.使用
this.$settings.BASE_URL
后台主页模块接口
1.软件开发模式
-瀑布模式:设计-->开发-->测试-->部署
-敏捷开发:设计-->开发-->测试-->开发-->测试...-->部署
-DevOps:设计-->开发-->测试-->部署-->开发-->测试-->部署...
2.创建app，写轮播图表
python ../../manage.py startapp home
3.将常用字段封装utils
from django.db import models\models.py
class BaseModel(models.Model):
created_time = models.DateTimeField(auto_now_add=True, verbose_name='创建时间')
updated_time = models.DateTimeField(auto_now=True, verbose_name='上次更新时间')
# 软删除:不真正删除数据，而使用字段控制
is_delete = models.BooleanField(default=False, verbose_name='是否删除')
is_show = models.BooleanField(default=True, verbose_name='是否上架')
orders = models.IntegerField(verbose_name='优先级')
class Meta:
# 虚拟表:只用来做继承，不在数据库生成
abstract = True
4.继承BaseModel编写Banner表
from django.db import models
from utils.models import BaseModel
class Banner(BaseModel):
# 是否
title = models.CharField(max_length=16, unique=True, verbose_name='名称')
image = models.ImageField(upload_to='banner', verbose_name='图片')
link = models.CharField(max_length=64, verbose_name='图片')
info = models.TextField(verbose_name='详情')
class Meta:
db_table = 'luffy_banner'
verbose_name_plural = '轮播图表'
def __str__(self):
return self.title
轮播图
1.分路由
from django.urls import path, include
urlpatterns = [
path('api/v1/home/', include('home.urls')),
]
2.home中urls.py
from rest_framework.routers import SimpleRouter
router = SimpleRouter()
router.register('banner', views.BannerView, 'banner')
urlpatterns = [
]
urlpatterns += router.urls
3.序列化类
from .models import Banner
from rest_framework import serializers
class BannerSerializer(serializers.ModelSerializer):
class Meta:
model = Banner
fields = ['title', 'image', 'link']
4.utils中的view.py
from rest_framework.mixins import ListModelMixin
from utils.response import APIResponse
class CommonListModelMixin(ListModelMixin):
def list(self, request, *args, **kwargs):
res = super().list(request, *args, **kwargs)
return APIResponse(result=res.data)
5.home视图类
from .models import Banner
from .serializer import BannerSerializer
from rest_framework.viewsets import GenericViewSet
from utils.views import CommonListModelMixin
class BannerView(GenericViewSet, CommonListModelMixin):
queryset = Banner.objects.all().filter(is_delete=False, is_show=True).order_by('orders')
serializer_class = BannerSerializer
'''
录入数据
-下载、注册simpleui，国际化
-创建超级用户
python manage.py createsuperuser
-录入数据
'''
跨域问
1.前后端交互存在跨域问题
-同源策略（Same origin policy）是一种约定，它是浏览器最核心也最基本的安全功能，如果缺少了同源策略，则浏览器的正常功能可能都会受到影响。可以说Web是构建在同源策略基础之上的，浏览器只是针对同源策略的一种实现
-请求的url地址,必须与浏览器上的url地址处于同域上,也就是域名,端口,协议相同.
比如:我在本地上的域名是127.0.0.1:8000,请求另外一个域名：127.0.0.1:8001一段数据
浏览器上就会报错，这个就是同源策略的保护,如果浏览器对javascript没有同源策略的保护,那么一些重要的机密网站将会很危险
2.解决跨域问题
-前端代理
-nginx代理
-cors解决跨域
3.cors解决跨域
-跨域资源共享，后端技术，核心就是在响应头中加入数据，允许浏览器接受数据
'cors需要浏览器和服务器同时支持，IE浏览器不能低于IE10'
3.1浏览器将CORS的请求分为两类:
-简单请求(simple request)
-非简单请求(not-so-simple request)
3.2简单请求
浏览器发出CORS简单请求，只需要在头信息之中增加一个Access-Control-Allow-Origin字段
3.3非简单请求
-浏览器发出CORS非简单请求，会在正式通信之前，先发送一个options请求，称为”预检”请求
-浏览器先询问服务器，当前网页所在的域名是否在服务器的许可名单之中，如果允许，再发真正的请求
3.4什么是简单请求、非简单请求:满足下面两种情况的就是简单请求
-请求方式是三种之一: HEAD、GET、POST
-HTTP的请求头信息不超出以下几种字段:
Accept
Accept-Language
Content-Language
Last-Event-ID
Content-Type:只限于三个值application/x-www-form-urlencoded、multipart/form-data、text/plain
4.使用cors解决跨域
4.1使用第三方模块
-安装django-cors-headers
-注册app
'corsheaders',
-加入中间件
'corsheaders.middleware.CorsMiddleware',
-配置文件配置
CORS_ALLOW_CREDENTIALS = True
# 允许所有域
CORS_ORIGIN_ALLOW_ALL = True
CORS_ORIGIN_WHITELIST = (
'*'
)
# 允许请求方式
CORS_ALLOW_METHODS = (
'DELETE',
'GET',
'OPTIONS',
'PATCH',
'POST',
'PUT',
'VIEW',
)
# 允许请求头
CORS_ALLOW_HEADERS = (
'XMLHttpRequest',
'X_FILENAME',
'accept-encoding',
'authorization',
'content-type',
'dnt',
'origin',
'user-agent',
'x-csrftoken',
'x-requested-with',
'Pragma',
)
4.2写下面的代码
def test(request):
print(request.method)
# 解决简单请求
res = HttpResponse('ok')
res['Access-Control-Allow-Origin'] = '*'
# 解决非简单请求
if request.method == 'OPTIONS':
res['Access-Control-Allow-Headers'] = 'Content-Type'
return res
自定义配置
'公共配置信息要放到单独一个配置文件中'
1.在settings.py中common_settings.py
# 轮播图显示的条数
BANNER_COUNT = 3
2.
from settings.common_settings import *
queryset = Banner.objects.all().filter(is_delete=False, is_show=True).order_by('orders')[:BANNER_COUNT]

腾讯云短信介绍和申请
1.要写发送短信接口，借助于短信运营商发短信
-腾讯云开放平台，有很多开放的接口供人使用，我们用的是短信
https://console.cloud.tencent.com/smsv2
2.申请使用短信
-签名类型
网站:要去工信部备案
公众号:申请个人一个公众号
https://mp.weixin.qq.com/
-
3.申请模板
发送短信的模板 {1} {2} 后期用代码填上
'申请后免费赠送100条，之后收费'
-代码发送短信参照文档
https://cloud.tencent.com/document/product/382/13444
api文档，sdk
1.API文档
-使用api调用，比较麻烦，需要固定输入，接收固定的返回
-使用postman都可以测试，但是要携带认证的秘钥
2.SDK(Software Development 软件开发工具包)
-SDK是分语言，它是基于API，使用某个编程语言的包
-例如python:pip install 包
包.发短信(参数)
3.腾讯短信SDK使用
1 已开通短信服务，创建签名和模板并通过审核。 # 开了
2 如需发送国内短信，需要先 购买国内短信套餐包。 #赠送了
3 已准备依赖环境：Python 2.7 - 3.6 版本。 # 我们有
4 已在访问管理控制台 >API密钥管理页面获取 SecretID 和 SecretKey。
SecretID 用于标识 API 调用者的身份。
SecretKey 用于加密签名字符串和服务器端验证签名字符串的密钥，SecretKey 需妥善保管
5 短信的调用地址为sms.tencentcloudapi.com。

课程板块相关表分析及创建
1.课程类型
-免费课----FreeCourse
-实战课----Course
-轻课----LightCourse
2.只写5个表(核心功能、你可以扩展、收藏功能、评论功能、咨询功能)
-CourseCategory 课程分类表 跟课程是一对多：一个分类下有多个实战课
-Course 实战课程表
-Teacher 老师表 一对多，一个老师可以录多门课程
-CourseChapter 章节表 章节和课程，一对多 一个课程对多个章节
-CourseSection 课时表 课时跟章节，一对多，一个章节有多个课时
3.创建课程app，创建表，迁移表
python manage.py makemigrations
python manage.py migrate
创建表

视频托管
1.当视频过多时，如果传到自己服务器放到media文件夹，会导致项目的并发量下降，所以我们可以把视频存储到第三方存储上
2.第三方七牛云：
-上海公司，技术驱动型公司(ceo:许式伟-国内第一批使用go语言的，全线go语言)
2.1七牛云：
-注册账号
-创建空间（桶）
-上传文件：
-1 直接上传
-2 使用代码上传
-python：sdk
-前端上传:js代码案例
# 公司内部存储：fastdfs

支付宝支付
1.支付宝支付官网sdk
https://opendocs.alipay.com/open/02no41
2.沙箱环境
Sandbox:程序的虚拟执行环境，不需要申请各种认证，直接写程序，后期只需要换成只是的秘钥即可
3.使用沙箱环境
-第三方的sdk：https://github.com/fzlee/alipay
-基于支付宝的API接口封装的，开源软件
pip3 install python-alipay-sdk
4.生成公钥私钥(支付宝提了一个生成的工具)
https://opendocs.alipay.com/open/02np9g
-生成公钥私钥，在本地(私钥好好保管)
4.1把公钥填在支付宝网站上(沙箱环境，正式环境)
-把公钥填进网站，会生成一个支付宝公钥，以后项目中咱们使用支付宝公钥来做
-https://openhome.alipay.com/platform/appDaily.htm?tab=info
支付宝支付基本使用
1.app_private_key.pem
-----BEGIN RSA PRIVATE KEY-----
通过支付宝公钥私钥签发软件签发的应用私钥
-----END RSA PRIVATE KEY-----
2.alipay_public_key.pem
-----BEGIN PUBLIC KEY-----
拿应用公钥跟支付宝换来的支付宝公钥
-----END PUBLIC KEY-----
3.

支付宝回调接口
1.支付成功，支付宝会有俩回调
1.1get回调，调前端
为了保证准确性，支付宝回调会前端后，我们自己向后端发送一个请求，查询一下这个订单是否支付成功
1.2post回调，调后端接口
-后端接口，接受支付宝的回调，修改订单状态
-这个接口不需要任何的认证和权限
-如果用户点了支付----》跳转到了支付宝页面---》你的服务挂机了---》支付宝在24小时内，会有8次回调
2.内网穿透
2.1支付宝在公网上，无法访问我们内网，在测试阶段，项目没上线，就无法完成回调
2.2通过第三方服务端，让局域网内的东西，可以被外网访问到
0 上线前准备
# 1 把logs做成了包
-忽略掉日志文件后，空文件夹不会被git管理，做成包后会被管理，咱们需要logs文件夹
# 2 新建了一个manage_pro.py
-服务端，迁移数据库，如果执行 python manage.py migrate 使用的数据库是测试环境
-服务端使用manage_pro.py，迁移到正式的数据库中
# 3 migrations 中得修改记录要不要提交到git
-官方建议：提交
-我建议：不要提
-改了后，有记录
-服务端：
python manage.py makemigrations
python manage.py migrate
-假设：
本地张三在user表增加了一个字段，migrations记录
本地张三在user表增加了一个字段，migrations记录
提到远端，服务端看到两个变更记录
服务端只需要执行python manage.py migrate
-我的建议：
本地张三在user表增加了一个字段，migrations记录
本地张三在user表增加了一个字段，migrations记录
不提到远端，服务端没有变更记录
服务端只需要执行
python manage.py makemigrations 只生成一条
python manage.py migrate
# 4 配置文件中得，后台和前台地址，修改，修改成上线服务器的地址，但是现在还没有
-在配置文件中配置好阿里云的地址
# 5 后端项目提交到git上
# 6 本地把前端项目打包：html，css，js
-修改ajax的地址
export default {
BASE_URL:'http://101.132.179.71:8080/api/v1/'
}
-编译
npm run build
-项目路径下出现dist文件夹：html，css，js
1 阿里云机器购买
# 1 有一台服务器：虚拟机，购买一台阿里云的：云服务器，相当于你去电脑城配了一台电脑

# 3 域名：万网： 域名解析
# 购买机器：（阿里云，腾讯，新用户都很便宜，虚拟机）
-包年包月：公司买，一买买几年
-按量付费：用一会，用完就释放：余额里必须大于100
-抢占式：空跑的资源，偏移卖给你，等有人正常买，空跑的越来越少，就会把抢占式实例释放调
-选择流量付费
-2核4g
-centos 7.9系统
-选公网ip
-自定义密码：root用户和自己写的密码
-确定购买成功

# 创建数据库用户，和数据库，再迁移表
1）管理员连接数据库
>: mysql -uroot -p
2）创建数据库
>: create database luffy default charset=utf8;
3）设置权限账号密码：账号密码要与项目中配置的一致
>: grant all privileges on luffy.* to 'luffy_api'@'%' identified by 'Luffy123?';
>: grant all privileges on luffy.* to 'luffy_api'@'localhost' identified by 'Luffy123?';
>: flush privileges;
4）退出mysql
>: quit;
10.3 迁移数据库
# manage.py --->dev.py
# manage_pro.py --->prod.py
python manage_pro.py makemigrations
python manage_pro.py migrate
# 表中没数据，加入点测试数据
# 把之前本地测试库中得数据导入
-本地的导出成sql
-在navicate上右键---》导出成sql
-导入到远端中取
-右键导入即可
10.4 使用uwsgi启动djagno
# 0 使用uwsgi跑之前先执行
python manage_pro.py runserver 0.0.0.0:8080
外部机器浏览器里输入：http://101.132.179.71:8080/api/v1/home/banner/就能访问到
# 1进行uwsgi服务配置，内容如下
>: vim ./luffyapi.xml # uwsgi的配置文件
<uwsgi>
<socket>127.0.0.1:8888</socket>
<chdir>/home/luffy_api/</chdir>
<module>luffy_api.wsgi</module>
<processes>4</processes>
<daemonize>uwsgi.log</daemonize>
</uwsgi>
# 2 启动uwsgi
uwsgi -x luffyapi.xml
# 3 查看uwsgi进程
ps aux |grep uwsgi
# 4 配置nginx，把8080的动态请求转发给8888端口
vim /usr/local/nginx/conf/nginx.conf
events {
worker_connections 1024;
}
http {
include mime.types;
default_type application/octet-stream;
sendfile on;
server {
listen 80;
server_name 127.0.0.1;
charset utf-8;
location / {
root /home/html;
index index.html;
try_files $uri $uri/ /index.html; # 解决vue路由问题
}
}
# 新增的server
server {
listen 8080;
server_name 127.0.0.1;
charset utf-8;
location / {
include uwsgi_params;
uwsgi_pass 127.0.0.1:8888;
uwsgi_param UWSGI_SCRIPT luffy_api.wsgi;
uwsgi_param UWSGI_CHDIR /home/luffy_api/;
}
}
}
# 重启nginx
nginx -s reload
11 路飞后台样式处理
# uwsgi 只转发动态请求，静态资源它不管
1）编辑线上配置文件
>: vim /home/luffy_api/luffy_api/settings/prod.py
2）修改static配置，新增STATIC_ROOT、STATICFILES_DIRS
STATIC_URL = '/static/'
STATIC_ROOT = '/home/luffy_api/luffy_api/static'
STATICFILES_DIRS = (os.path.join(BASE_DIR, "../static"),)
3）退出编辑
>: esc
>: :wq
4）项目目录下没有 static 文件夹需要新建
>: mkdir /home/luffy_api/static 之前混合项目放静态文件
>: mkdir /home/luffy_api/luffy_api/static 收集静态文件的
5）完成静态文件迁移
>: python /home/luffy_api/manage_pro.py collectstatic
-python manage_pro.py collectstatic
6）1）修改nginx配置
>: vim /usr/local/nginx/conf/nginx.conf
events {
worker_connections 1024;
}
http {
include mime.types;
default_type application/octet-stream;
sendfile on;
server {
listen 80;
server_name 127.0.0.1;
charset utf-8;
location / {
root /home/html;
index index.html;
try_files $uri $uri/ /index.html; # 解决vue路由问题
}
}
server {
listen 8080;
server_name 127.0.0.1;
charset utf-8;
location / {
include uwsgi_params;
uwsgi_pass 127.0.0.1:8888;
uwsgi_param UWSGI_SCRIPT luffyapi.wsgi;
uwsgi_param UWSGI_CHDIR /home/luffyapi/;
}
# 上面都是之前的
location /static {
alias /home/luffy_api/luffy_api/static;
}
}
}
# 重启nginx
nginx -s reload
