Requirements

ElastiCache (redis) instance
your Django app
git
pip package manager

install redis

install redis by below command

pip install redis

Copy the part of django-redis-sessions in your project directory

Clone to any directory

Clone git repository wherever you want to put.

git clone https://github.com/martinrusev/django-redis-sessions#django-redis-sessions

Copy redis_sessions to your project directory

Copy redis_sessions directory in django-redis-sessions to your project directory.

cp -r redis_sessions your_directory

Edit session.py and your settings.py

Open below files with editor, and add the codes.

# session.py

    def get(self):
        ...
        elif self.connection_type == 'redis_host':
        ...
            db=settings.SESSION_REDIS_DB,
            # add below code
            SSL=True,


# settings.py

# add below code
SESSION_ENGINE = 'your_directory.redis_sessions.session'

SESSION_REDIS = {
    'host': 'your_aws_elasticache_endpoint_name',
    'port': your_port,
    'db': 0,
    'password': your_password,
    'prefix': 'session',
    'socket_timeout': 3,
    'retry_on_timeout': False
}

※ In your password setting, using encryption middleware such as django-environ, python-decouple is better.

The reason why we edit session.py is to use SSL mode. By doing that, we can connect to ElastiCache by SSL tunnel mode.

Finish! Check Connection

Confirm by running the server, testing, or connecting to ElastiCache directly, etc.

I hope I can help you to deploy your Django app to AWS!!
