如何在 aws ec2 实例上运行现有的 Django 应用程序？

Question

I am trying to run a Django application on AWS Ec2 instance. I've chosen Ubuntu as my platform. After cloning the git repository, and creating a virtual environment, I have installed all apps in my requirements.txt. When I try to the following lines of code python3 manage.py migrate ; python3 manage.py check ; python3 manage.py runserver the following error is coming up.

django.db.utils.OperationalError: connection to server at "localhost" (127.0.0.1), port 5432 failed: FATAL: password authentication failed for user "columbus_db" connection to server at "localhost" (127.0.0.1), port 5432 failed: FATAL: password authentication failed for user "columbus_db"

My settings.py file looks like this

 DATABASES = {
# 'default': {
#     'ENGINE': 'django.db.backends.sqlite3',
#     'NAME': os.path.join(BASE_DIR, 'db.sqlite3'),
# }'default': {
    'ENGINE': 'django.db.backends.postgresql_psycopg2',  # Database Engine of PostgreSQL Database
    'NAME': 'columbus_db',  # Database Name
    'USER': 'columbus_db',  # Database has a Root User
    'PASSWORD': 'columbus',  # Database Connection Password
    'HOST': "localhost",  # IP Address for Localhost
}

What can I change in settings.py or Ec2 Instance settings to start the application and see it at Ec2 IP address?

Answer 1

You are missing a running database, the app code except it to be PostgreSQL, you have multiple choices:

• Install and run a local PostgreSQL instance directly in your EC2
• Use Amazon's managed database RDS
• Use Sqlite which is simple to setup and doesn't require more configuration, but your app might required specific PostgreSQL features
