• msi 다운로드 후 인스톨 (안 하면 에러남)

cmd

pip install django-redis

settings.py

CACHES = {
    "default": {
        "BACKEND": "django_redis.cache.RedisCache",
        "LOCATION": "redis://127.0.0.1:6379/1", #-> 여기서 1은 DB이름인 것 같음
        "OPTIONS": {
            "CLIENT_CLASS" : "django_redis.client.DefaultClient",

현업의 경우

채팅:

CHANNEL_LAYERS = {
    'default' : {
        'BACKEND' : 'channels_redis.core.RedisChannelLayer',
        'CONFIG' : {
            'hosts': [(REDIS_LOCATION_PRIMARY, 6379)],
        }
    }
}

캐싱:

CACHE_TTL = 30
CACHES = {
    "default": {
        "BACKEND": "django_redis.cache.RedisCache",
        "LOCATION": [ REDIS_LOCATION_PRIMARY, REDIS_LOCATION_REPLICA],
        "OPTIONS": {
            "CLIENT_CLASS" : "django_redis.client.DefaultClient",
            "MASTER_CACHE": REDIS_LOCATION_PRIMARY,
        }
    }
}

AWS

• AWS Elasticache의 대쉬보드에서 엔드포인트를 따온다
• 엔드포인트 앞에 http://가 붙지 않고 뒤에 6379 포트번호도 떼준다
