如何将EC2中的Django连接到RDS中的Postgres数据库？

Question

First time using AWS services with Django.

Was wondering how to configure the Django app running in a EC2 instance to a Postgres database in RDS?

the EC2 is running ubuntu 14.04

Any special configuration required?

Answer 1

All you need to do, before doing the normal migration documented in the official tutorial be sure to have your RDS instance available and accessible to your EC2 instance .

Then what you need to do, is to modify the settings.py file of your app in the DATABSES section in the following way

DATABASES = {
'default': {
    'ENGINE': 'django.db.backends.postgresql',
    'NAME': '<name defined upon RDS creation>',
    'USER': '<username defined upon RDS creation>',
    'PASSWORD': '<password defined upon RDS creation>',
    'HOST': '<this can be found in "Endpoint" on your RDS dashboard, exclude the ":" and the port number>',
    'PORT': '5432',
    }
}

Following this, continue to migrate normally and all should work well.

If you are able to use a deployment service, take a look at at AWS Elastic Beanstalk . It combines EC2, RDS and S3 storage into a Docker and helps keep them together. It's really easy to connect your RDS instance to your EC2 instance(s). I just launched a Django project using that a few weeks ago.
