如何将开发阶段的Django Web应用程序连接到现有的AWS MySQL数据库？

Question

Short question - How do I connect to an existing Amazon Web Services MySQL database from my development-stage Django web app?

Context:

I am working on creating a webpage using the Django framework.

I've successfully created an AWS MySQL RDS database and have imported my data and connected to it successfully via MySQL Workbench.

I am now at a point where I am trying to connect to the database from my Django app. I will require read-only functionality from the database from within the app... I will not be writing any new info to the database. Furthermore, I am trying to do this within a development environment, as I am not even close to anything production worthy (ie, I am working locally off of my laptop).

I've added the AWS database information to my Django settings.py file, and based on my research, to generate the requisite models I'll need to utilize Django's 'inspectdb' utility. I've tried that, and the resulting error received was:

django.db.utils.OperationalError: (1045, u"Access denied for user '[ my username was here, which actually showed my literal first name rather than any type of username that was established by AWS ]'@'pool-[ my IP address was here ].nwrknj.fios.verizon.net'

Has anyone else experienced this issue and identified a solution?

DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.sqlite3',
        'NAME': os.path.join(BASE_DIR, 'db.sqlite3'),
    },
    '[removed]': {
          'NAME': '[removed]',
          'ENGINE': 'django.db.backends.mysql',
          'USERNAME': '[removed]',
          'PASSWORD': '[removed]',
          'HOST': '[removed].us-west-2.rds.amazonaws.com',
          'PORT': '3306'

Answer 1

Unless you have DATABASE_ROUTERS set to use an alternate database, everything in Django will use the default database. Get rid of the current ENGINE and NAME in default and move all the [removed] db info into default .

Also make sure that the AWS RDS port 3306 is open to your FIOS IP address. Ideally you would restrict it in AWS to only the actual servers (whether on AWS or elsewhere) but for now you may have to set a broad IP range to allow for your FIOS IP changing periodically during development.
