負笈在线 2023-10-09 原文

一、Python Install(兼容python2/python3)

python3(python-3.6.8-amd64.exe) install
--D:\Python36
python2(python-2.7.16.amd64.msi) install
--D:\Python27

二、python2/python3及pip2/pip3共存问题解决

参考URL：

C:\Users\Administrator>python2
Python 2.7.16 (v2.7.16:413a49145e, Mar  4 2019, 01:37:19) [MSC v.1500 64 bit (AMD64)] on win32
Type "help", "copyright", "credits" or "license" for more information.

>>> exit()

C:\Users\Administrator>python3
>>> Python 3.6.8 (tags/v3.6.8:3c6b436a57, Dec 24 2018, 00:16:47) [MSC v.1916 64 bit (AMD64)] on win32
>>> Type "help", "copyright", "credits" or "license" for more information.
>>> exit()

C:\Users\Administrator>pip2 -V
>>> pip 20.3.4 from d:\python27\lib\site-packages\pip (python 2.7)

C:\Users\Administrator>pip3 -V
pip 21.3.1 from d:\python36\lib\site-packages\pip (python 3.6)

三、pip源(国内)配置

新建配置文件C:\Users\Administrator\pip\pip.ini，编辑内容如下：

[global]
index-url = http://mirrors.aliyun.com/pypi/simple/
[install]
trusted-host = mirrors.aliyun.com

常见国内镜像源
（1）阿里云 http://mirrors.aliyun.com/pypi/simple/
（2）豆瓣http://pypi.douban.com/simple/
（3）清华大学 https://pypi.tuna.tsinghua.edu.cn/simple/
（4）中国科学技术大学 http://pypi.mirrors.ustc.edu.cn/simple/
（5）华中科技大学http://pypi.hustunique.com/

四、虚拟环境安装

C:\Users\Administrator>pip3 install virtualenv
C:\Users\Administrator>pip3 install virtualenvwrapper-win
C:\Users\Administrator>pip2 install virtualenv
C:\Users\Administrator>pip2 install virtualenvwrapper-win

设置系统变量 WORKON_HOME

命令：创建虚拟环境

mkvirtualenv test
mkvirtualenv  -p python2 test2
mkvirtualenv  -p python3 test2

命令：列出虚拟环境

workon

命令：进入虚拟环境

workon test
pip list
python

命令：退出虚拟环境

deactivate

命令：删除虚拟环境

rmvirtualenv test

五、创建Django项目虚拟环境

C:\Users\Administrator>mkvirtualenv -p python3 local_cmdb
(local_cmdb) C:\Users\Administrator>workon local_cmdb
(local_cmdb) C:\Users\Administrator>pip -V

六、安装Django：

(local_cmdb) C:\Users\Administrator>cd D:\python_work\local_cmdb
(local_cmdb) C:\Users\Administrator>D:
(local_cmdb) D:\python_work\local_cmdb>django-admin startproject local_cmdb
(local_cmdb) D:\python_work\local_cmdb>cd local_cmdb
(local_cmdb) D:\python_work\local_cmdb\local_cmdb>python3 manage.py runserver 0.0.0.0:8000

You have 18 unapplied migration(s). Your project may not work properly until you apply the migrations for app(s): admin, auth, contenttypes, sessions.
Run 'python manage.py migrate' to apply them.

七、MYSQL安装配置

参考URL:
https://baijiahao.baidu.com/s?id=1734145282045952263&wfr=spider&for=pc
https://downloads.mysql.com/archives/installer/

MYSQL_VERSION:5.7.39

C:\Users\Administrator>mysql -u root -p
Enter password: ******
Welcome to the MySQL monitor.  Commands end with ; or \g.
Your MySQL connection id is 57
Server version: 5.7.39-log MySQL Community Server (GPL)
mysql> create database local_cmdb;
Query OK, 1 row affected (0.00 sec)

mysql>

修改默认的sqlite数据库为mysql

(local_cmdb) D:\python_work\local_cmdb\local_cmdb>pip3 install mysqlclient==2.0.0
(local_cmdb) D:\python_work\local_cmdb\local_cmdb>python3 manage.py migrate

(local_cmdb) D:\python_work\local_cmdb\local_cmdb>python3 manage.py createsuperuser
Username (leave blank to use 'administrator'): luorf

再启动服务

(local_cmdb) D:\python_work\local_cmdb\local_cmdb>python3 manage.py runserver 0.0.0.0:8000

访问http://127.0.0.1:8000/admin/

八、整合simpleui模板

(local_cmdb) D:\python_work\local_cmdb\local_cmdb>pip3 install simpleui

修改配置文件 settings.py

import os        ##追加1
from pathlib import Path

INSTALLED_APPS = [
    'simpleui',                              #追加2
    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',
]

STATIC_URL = '/static/'
STATIC_ROOT = os.path.join(BASE_DIR, "static")            #追加3

(local_cmdb) D:\python_work\local_cmdb\local_cmdb>dir
 Volume in drive D has no label.
 Volume Serial Number is 000A-D386

 Directory of D:\python_work\local_cmdb\local_cmdb

2023/01/05  17:43    <DIR>          static
               2 File(s)            688 bytes
               4 Dir(s)   6,932,615,168 bytes free

克隆资源：

(local_cmdb) D:\python_work\local_cmdb\local_cmdb>python3 manage.py collectstatic

重启服务

(local_cmdb) D:\python_work\local_cmdb\local_cmdb>python3 manage.py runserver
