阿里云CentOS7下部署Django+uwsgi+pip3+pytz+python3

环境：

CentOS==7.6

Nginx==1.14

Python==3.6

pip3==8.0.2

Django==2.1.7

pytz==2018.9

uwsgi==2.0.18

更新一次系统软件

yum update -y

依赖环境

yum -y groupinstall "Development tools"
yum install openssl-devel bzip2-devel expat-devel gdbm-devel readline-devel sqlite-devel psmisc

 安装python3

cd /usr/local
wget https://www.python.org/ftp/python/3.6.6/Python-3.6.6.tgz
tar -zxvf Python-3.6.6.tgz
cd Python-3.6.6
./configure --prefix=/usr/local/python3 && make && make install
ln -s /usr/local/python3/bin/python3.6 /usr/bin/python3
ln -s /usr/local/python3/bin/pip3.6 /usr/bin/pip3

 如果这个pip3安装报错不上，用下面的方法

 1 1.依赖
 2 yum install openssl-devel -y 
 3 yum install zlib-devel -y
 4 2.安装setuptools
 5 wget --no-check-certificate https://pypi.python.org/packages/source/s/setuptools/setuptools-19.6.tar.gz#md5=c607dd118eae682c44ed146367a17e26 
 6 tar -zxvf setuptools-19.6.tar.gz 
 7 cd setuptools-19.6
 8 python setup.py build 
 9 python setup.py install
10 3.安装pip3
11 wget --no-check-certificate https://pypi.python.org/packages/source/p/pip/pip-8.0.2.tar.gz#md5=3a73c4188f8dbad6a1e6f6d44d117eeb 
12 tar -zxvf pip-8.0.2.tar.gz 
13 cd pip-8.0.2 
14 python setup.py build 
15 python setup.py install
16 ln -s /usr/local/python3.6/bin/pip3 /usr/bin/pip3

安装virtualenv，方便不同版本项目的管理

1 pip3 install virtualenv
2 ln -s /usr/local/python3/bin/virtualenv /usr/bin/virtualenv
3 mkdir -p /data/env    #存放env文件
4 mkdir -p /data/wwwroot    #存放用户文件
5 virtualenv --python=/usr/bin/python3 pyweb    #指定版本的虚拟环境

启动虚拟环境

source activate
如果前面出现(pyweb)就是说明进入虚拟环境

 虚拟环境安装pip3，django，uwsgi

pip3 install django （如果用于生产的话，则需要指定安装和你项目相同的版本）
pip3 install uwsgi

这个时候在系统里面也需要安装一次，并且创建软连接

ln -s /usr/local/python3/bin/uwsgi /usr/bin/uwsgi

然后开始创建一个新的django项目

django-admin.py startproject mysite    #名字可以自定义

创建完之后/data/wwwroot/下会有一个mysite文件夹，项目就在这个文件夹里面

创建一个名叫blog的APP

python3 manage.py startapp blog

进入项目文件夹/data/wwwroot/mysite,添加static和templates，分别用于存放静态文件和模板文件。
编辑项目里mysite/settings.py文件

vim /data/wwwroot/mysite/mysite/settings.py

 在INSTALLED_APPS 列表里最后一行添加'blog'，注意，后面要加上一个逗号','

在我们刚才创建的templates下添加inde.html文件写一个网站

vim /data/wwwroot/mystie/templates/index.html
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title>Django</title>
</head>
<body>
<h1>Django website</h1>
</body>
</html>

配置URL

vim /data/wwwroot/mysite/mysite/urls.py
"""mysite URL Configuration

The `urlpatterns` list routes URLs to views. For more information please see:
    https://docs.djangoproject.com/en/2.1/topics/http/urls/
Examples:
Function views
    1. Add an import:  from my_app import views
    2. Add a URL to urlpatterns:  path('', views.home, name='home')
Class-based views
    1. Add an import:  from other_app.views import Home
    2. Add a URL to urlpatterns:  path('', Home.as_view(), name='home')
Including another URLconf
    1. Import the include() function: from django.urls import include, path
    2. Add a URL to urlpatterns:  path('blog/', include('blog.urls'))
"""
from django.contrib import admin
from django.urls import path
from blog import views          #导入模块   

urlpatterns = [
    path('admin/', admin.site.urls),
    path('', views.index),          #添加
]
~

编辑BlogAPP下的views.py

vim /data/wwwroot/mysite/blog/views.py
def index(request):
    return render(request, 'index.html')

变成这个样子

from django.shortcuts import render
def index(request):
    return render(request, 'index.html')
# Create your views here.
~                                                                                                                                                                                                                                                                                                                                                                             
~

启动项目

启动目录
/data/wwwroot/mysite
启动命令
python3 manage.py runserver

出现报错不会有其他原因就是配置文件写错了，仔细检查，出现需要CONTROL-C打断就是启动成功了

UWSGI

Django正常运行来配置启动uwsgi

网站项目路径是 /data/wwwroot/mysite/,在项目根目录下创建
mysite.xml文件

<uwsgi>    
   <socket>127.0.0.1:8997</socket> 　　　　　　<!-- 内部端口，自定义 --> 
   <chdir>/data/wwwroot/mysite/</chdir> 　　　　<!-- 项目路径 -->            
   <module>mysite.wsgi</module>  　　　　　　<!-- my　site为wsgi.py所在目录名--> 
   <processes>4</processes> 　　　　　　　　<!-- 进程数 -->     
   <daemonize>uwsgi.log</daemonize> 　　　　<!-- 日志文件 -->
</uwsgi>

接下来配置Nginx就不详情写

nginx的配置文件,路径要写对

events {
    worker_connections  1024;
}
http {
    include       mime.types;
    default_type  application/octet-stream;
    sendfile        on;
    server {
        listen 80;
        server_name  0.0.0.0;   #有域名写域名，没有域名写ip:80
        charset utf-8;
        location / {
           include uwsgi_params;
           uwsgi_pass 127.0.0.1:8997;
           uwsgi_param UWSGI_SCRIPT mysite.wsgi;
           uwsgi_param UWSGI_CHDIR /data/wwwroot/templates/;

        }
        location /static/ {
        alias /data/wwwroot/mysite/static/;
        }
    } 
}

修改配置文件

vim /data/wwwroot/mysite/mysite/settings.py

关闭DEBUG

DEBUG = False

进入项目源码的目录

cd /data/wwwroot/mysite/
uwsgi -x mysite.xml

然后进入nginx的sbin目录

(pyweb) [root@Test-server mysite]# cd /usr/local/nginx/sbin/
(pyweb) [root@Test-server sbin]# nginx -t
nginx: the configuration file /usr/local/nginx/conf/nginx.conf syntax is ok
nginx: configuration file /usr/local/nginx/conf/nginx.conf test is successful
(pyweb) [root@Test-server sbin]# nginx -s reload

通过域名或者局域网ip就可以访问了
