Based centos7, python3.7 new first Django project

In order to understand the entire site service better, you need to understand the link between the front, back, and this time you have the need to use the Django framework, Django's own template-based band, it can be better to receive a user request , then explain the first steps of a new Django project:
1: preparing the environment:
a virtual machine or server
centos7
python3 more than
2: installing django

        [root@bobo ~]# python3 -m venv myvenv #使用这条命令会在root用户的目录下生出myvenv这个文件夹，若不能生出，则是python3是否正常安装    
        [root@bobo ~]#  source myvenv/bin/activate #进入python环境下的虚拟环境
        (myvenv) [root@bobo ~]# pip3 list
            Package    Version
            ---------- -------
                pip        18.1   
               setuptools 40.6.2 
          (myvenv) [root@bobo ~]#  pip install django==2.2.5 #进行安装Django，版本选择当下最新的                    
           2.25
            (myvenv) [root@bobo ~]# cd myvenv/
            (myvenv) [root@bobo myvenv]# ls
             bin  include  lib  lib64  pyvenv.cfg
             (myvenv) [root@bobo myvenv]#  django-admin startproject mysite .#创建一个django项目，名字叫mysite
             (myvenv) [root@bobo myvenv]# ls
              bin  include  lib  lib64  manage.py  mysite  pyvenv.cfg
              (myvenv) [root@bobo myvenv]#  python3 manage.py migrate #接下来进行初始化，类似于编译
              raise ImproperlyConfigured('SQLite 3.8.3 or later is required (found %s).' % Database.sqlite_version)
             django.core.exceptions.ImproperlyConfigured: SQLite 3.8.3 or later is required (found 3.7.17).
             #上门是报错信息，表示django需要的数据库和python3.7的版本自带的不匹配，需要升级SQLit，下面是升级步骤
             (myvenv) [root@bobo myvenv]# cd ~
             (myvenv) [root@bobo ~]# wget https://www.sqlite.org/2019/sqlite-autoconf-3270200.tar.gz
             (myvenv) [root@bobo ~]# tar -zxvf sqlite-autoconf-3270200.tar.gz
             (myvenv) [root@bobo ~]# cd sqlite-autoconf-3270200
             (myvenv) [root@bobo sqlite-autoconf-3270200]# ls
             (myvenv) [root@bobo sqlite-autoconf-3270200]# ./configure --prefix=/usr/local
             (myvenv) [root@bobo sqlite-autoconf-3270200]#  make && make install
             (myvenv) [root@bobo sqlite-autoconf-3270200]# export LD_LIBRARY_PATH="/usr/local/lib"
             (myvenv) [root@bobo sqlite-autoconf-3270200]# mv /usr/bin/sqlite3  /usr/bin/sqlite3_old
             (myvenv) [root@bobo sqlite-autoconf-3270200]# ln -s /usr/local/bin/sqlite3   /usr/bin/sqlite3
             (myvenv) [root@bobo sqlite-autoconf-3270200]# sqlite3 --version #到这里就可以看到是否更新好了
             3.27.2 2019-02-25 16:06:06 bd49a8271d650fa89e446b42e513b595a717b9212c91dd384aab871fc1d0f6d7

3: Next is the configuration and operation of a project that comes with Django App

             (myvenv) [root@bobo sqlite-autoconf-3270200]# cd ..
              (myvenv) [root@bobo ~]# cd myvenv/
              (myvenv) [root@bobo myvenv]# cd mysite/
              (myvenv) [root@bobo mysite]# ls
              __init__.py  __pycache__  settings.py  urls.py  wsgi.py
             (myvenv) [root@bobo mysite]# vi settings.py #在这里需要三项内容1:TIME_ZONE = 'Europe/Berlin'改成 Asia/Shanghai2:在末尾添加STATIC_ROOT = 
             os.path.join(BASE_DIR, 'static')这是指定存放静态文件的，第三项，允许访问的主机，这里代表所有主机都可访问ALLOWED_HOSTS = ['*']
             [root@bobo myvenv]# python manage.py migrate #重新进入初始化
             [root@bobo myvenv]# python3 manage.py runserver 0.0.0.0:8000#运行，输入本地的IP加端口测试，就可以显示页面了，不过一般来说需要等几秒，多 
             刷新刷新吧，运行之后是一直启动的，关闭之后就收不到了。
             (myvenv) [root@bobo myvenv]# python3 manage.py createsuperuser #这条命令可以创建管理Django后台服务的超级管理员，输入用户，邮箱，密码名 
              就好了
