[Django] Configure MySQL database, Redis database

1. Configure MySQL database

For the method of installing MySQL database in Django, please refer to the previous article
. Field types and constraints of changing Django database to MySQL and ORM

After installation, we only need to modify the DATABASES list in the configuration file (dev.py here)

DATABASES = {
    
    
    'default': {
    
    
        'ENGINE': 'django.db.backends.mysql', # 数据库引擎
        'HOST': '127.0.0.1', # 数据库主机
        'PORT': 3306, # 数据库端口
        'USER': 'root', # 数据库用户名
        'PASSWORD': '123456', # 数据库用户密码
        'NAME': 'XXXX' # 数据库名字
    },
}

2. Configure Redis database

Install django-redis

pip install django-redis -i https://pypi.tuna.tsinghua.edu.cn/simple/

Add Redis related configuration in the configuration file

CACHES = {
    
    
    # 默认存储信息: 存到 0 号库
    "default": {
    
     
        "BACKEND": "django_redis.cache.RedisCache",
        "LOCATION": "redis://127.0.0.1:6379/0",
        "OPTIONS": {
    
    
            "CLIENT_CLASS": "django_redis.client.DefaultClient",
        }
    },
    # session 信息: 存到 1 号库
    "session": {
    
     
        "BACKEND": "django_redis.cache.RedisCache",
        "LOCATION": "redis://127.0.0.1:6379/1",
        "OPTIONS": {
    
    
            "CLIENT_CLASS": "django_redis.client.DefaultClient",
        }
    },
}
SESSION_ENGINE = "django.contrib.sessions.backends.cache"
SESSION_CACHE_ALIAS = "session"
