使用Elastic BeanStalk + Django设置ElastiCache Redis [英] Setting up ElastiCache Redis with Elastic BeanStalk + Django

问题描述

另一个stackoverflow answer 说，您需要进行设置一个lasticache.config文件，以使用ElastiCache自动创建Redis服务器.

Another stackoverflow answer says you need to set up a elasticache.config file to create Redis servers with ElastiCache automatically.

但是，我可以仅在AWS(Elasticache)上创建Redis实例并将其端点添加到Django设置中吗?例如，使用 Django-redis :

However, can I just create a Redis instance on AWS (Elasticache) and add its endpoint into Django settings? Eg, with Django-redis:

CACHES = {
    "default": {
        "BACKEND": "django_redis.cache.RedisCache",
        "LOCATION": "redis://<REDIS AWS ENDPOINT AND PORT HERE>",
        "OPTIONS": {
            "CLIENT_CLASS": "django_redis.client.DefaultClient",
        }
    }
}

我怀疑以上情况可能会导致多个beantalk服务器实例出现问题.鉴于此，鉴于有一个显式编写的用于与AWS Elasticache for Memcache接口的Django包，我很想使用MemCache而不是Redis:

I suspect the above could cause trouble with multiple beanstalk server instances. Given this, I am tempted to use MemCache and not Redis, given that there is a Django package written explicitly for interfacing with AWS Elasticache for Memcache: django-elasticache.

谢谢， 安迪.

推荐答案

简短答案:是.

长答案:我还没有使用过Elastic Beanstalk，但是我可以确认，如果您在ElastiCache中创建Redis 实例(即:禁用集群模式)，则可以在django-redis下正常工作.只需将primary_endpoint插入您发布的Django配置中即可.

Long answer: I have not used Elastic Beanstalk, however I can confirm that if you create a Redis instance (that is: cluster mode disabled) in ElastiCache it will work fine with django-redis. Just insert the primary_endpoint into the Django config you posted.

如果您打算使用只读副本，请按以下步骤进行设置:

N.B. If you plan to use read replicas, set it up like this:

CACHES = {
    "default": {
        "BACKEND": "django_redis.cache.RedisCache",
        "LOCATION": [
            "redis://<MASTER ENDPOINT>",
            "redis://<SLAVE ENDPOINT>",
        ]
        "OPTIONS": {
            "CLIENT_CLASS": "django_redis.client.DefaultClient",
        }
    }
}

但是，如果启动Redis 集群，则不能使用香草django-redis.您必须按照 redis-py-cluster https://github.com/niwinz/django-redis/issues/208#issuecomment-352585533"rel =" noreferrer>在这篇文章中.复制到这里:

If you spin up a Redis cluster however, you cannot use vanilla django-redis. You'll have to use use redis-py-cluster with it as described in this post. Replicated here:

CACHES = {
  'default': {
    'BACKEND': 'django_redis.cache.RedisCache',
    'LOCATION': 'redis://XXX.YYY.ZZZ.cache.amazonaws.com/0',
    'OPTIONS': {
      'REDIS_CLIENT_CLASS': 'rediscluster.RedisCluster',
      'CONNECTION_POOL_CLASS': 'rediscluster.connection.ClusterConnectionPool',
      'CONNECTION_POOL_KWARGS': {
        'skip_full_coverage_check': True # AWS ElasticCache has disabled CONFIG commands
      }
    }
  }
}
