配置後端開發環境

安裝python3.6.4

#安裝依賴包
yum install openssl-devel readline-devel unzip -y

#編譯安裝
tar xf Python-3.6.4.tgz
cd Python-3.6.4
./configure  --prefix=/usr/local/python36 --enable-optimizations
make && make install

#配置環境
vim /etc/profile.d/py3.sh
    export PATH=$PATH:/usr/local/python36/bin
source 
 
/etc/profile.d/py3.sh

安裝virtualenvwrapper

/usr/local/python36/bin/pip3 install virtualenvwrapper

#在varant賬號下編輯
$ vim .bashrc
...
VIRTUALENVWRAPPER_PYTHON=/usr/local/python36/bin/python3
if [ -f /usr/local/python36/bin/virtualenvwrapper.sh ]; then
    export WORKON_HOME=$HOME/.virtualenvs
    source 
 
/usr/local/python36/bin/virtualenvwrapper.sh
fi

創建虛擬環境

mkvirtualenv --python="/usr/local/python36/bin/python3" devops_env

#在虛擬環境中安裝常用工具
pip install ipython
pip install requests

安裝mariadb

yum install -y mariadb mariadb-server mariadb-devel

#在[mysqld]下新增以下內容
default
 
-storage-engine  =innodb
innodb_file_per_table = 1
collation-server = utf8_general_ci
init-connect = ‘SET NAMES utf8‘
character-set-server = utf8

#啟動mariadb並設置開機啟動
sudo systemctl start mariadb
sudo systemctl enable mariadb

#初始化
mysql_secure_installation

#創建數據庫
create database devops CHARACTER SET utf8;

準備django環境

# 進入虛擬環境
workon devops

#安裝django
pip install "django >1.11, <2.0"

#安裝mysqlclient
pip install mysqlclient

#創建django項目
(devops) heboan@heboan-PC:~$ mkdir app
(devops) heboan@heboan-PC:~$ cd app
(devops) heboan@heboan-PC:~/app$ django-admin startproject devops

#使用pycharm打開devops項目,並配置編譯器為虛擬環境devops

#配置dajngo連接mariadb, settings.py
...
DATABASES = {
    ‘default‘: {
        ‘ENGINE‘: ‘django.db.backends.mysql‘,
        ‘NAME‘: ‘devops‘,
        ‘USER‘: ‘root‘,
        ‘PASSWORD‘: ‘root‘,
        ‘HOST‘: ‘127.0.0.1‘,
        ‘PORT‘: 3306,
        ‘OPTIONS‘: {
            ‘init_command‘: ‘SET default_storage_engine=INNODB;‘,
        },
    }
}

#配置語言和時區
LANGUAGE_CODE = ‘zh-hans‘
TIME_ZONE = ‘Asia/Shanghai‘
USE_I18N = True
USE_L10N = True
USE_TZ = False

# 配置django項目的運行
    在pycharm中點擊manage.py運行一次
    Run -->Edit Configurations
    Script parameters: runserver 0.0.0.0:8000

app目錄規範

後期的開發中，我們會根據不同的功能模塊創建app,為了維護方便，我們在項目目錄下創建Python package命名為apps, 以後所有創建的app都放在apps下

右鍵apps, Mark Directory as Sources Root

編輯setting.py

sys.path.index(0, os.path.join(BASE_DIR, ‘apps‘))

配置DRF

安裝reset framework

pip install djangorestframework
pip install markdown
pip install django-filter

Add ‘rest_framework‘ to your INSTALLED_APPS setting.

INSTALLED_APPS = (
    ...
    ‘rest_framework‘,
)
