How to Connect a Django App to AWS RDS PostgreSQL Database

*YouTube Title:* 🔹 How to Connect a Django App to AWS RDS PostgreSQL Database | Step-by-Step Guide --- *YouTube Description:* 🚀 *Learn How to Connect a Django App to AWS RDS PostgreSQL Database!* In this tutorial, I’ll guide you through *setting up an AWS RDS PostgreSQL database* and connecting it to your *Django application**. If you're developing a **scalable Django app* and need a **managed PostgreSQL database**, this is the perfect solution! --- 🔹 *What You’ll Learn:* ✅ How to *create a PostgreSQL database on AWS RDS* ✅ How to *configure security groups for remote access* ✅ How to *install and configure PostgreSQL in Django* ✅ How to *connect Django to AWS RDS PostgreSQL* ✅ How to *migrate Django models to RDS* --- 🔹 *Prerequisites:* ✔️ A *Django project* set up on your local machine ✔️ An *AWS account* ([Sign up here](https://aws.amazon.com/)) ✔️ Basic understanding of *PostgreSQL and Django databases* --- *Step 1: Create a PostgreSQL Database on AWS RDS* 1️⃣ *Log in to AWS Console* → Navigate to *RDS Service* 2️⃣ Click *Create database* 3️⃣ Select *Standard create* 4️⃣ Choose *PostgreSQL* as the database engine 5️⃣ Set up database details: **DB instance identifier**: `mydb-instance` **Master username**: `admin` **Master password**: `yourpassword` 6️⃣ Under Connectivity, *enable Public Access* (for development) 7️⃣ Select a security group that *allows inbound PostgreSQL connections (port 5432)* 8️⃣ Click *Create database* and wait for it to be available --- *Step 2: Install PostgreSQL Client on Your System* To connect Django to AWS RDS, install the PostgreSQL client: 🔹 *On Ubuntu/Linux:* ```bash sudo apt update sudo apt install postgresql-client ``` 🔹 *On macOS:* ```bash brew install postgresql ``` 🔹 *On Windows:* [Download PostgreSQL](https://www.postgresql.org/download/) and install it. Verify installation with: ```bash psql --version ``` --- *Step 3: Install PostgreSQL Adapter for Django* Inside your *Django project* folder, activate your virtual environment and install `psycopg2`: ```bash pip install psycopg2-binary ``` --- *Step 4: Configure Django Settings for AWS RDS PostgreSQL* In your Django **settings.py**, update the `DATABASES` section: ```python DATABASES = { 'default': { 'ENGINE': 'django.db.backends.postgresql', 'NAME': 'your-db-name', # Replace with your AWS RDS database name 'USER': 'your-username', # AWS RDS username 'PASSWORD': 'your-password', # AWS RDS password 'HOST': 'your-db-endpoint.rds.amazonaws.com', # AWS RDS endpoint 'PORT': '5432', # Default PostgreSQL port } } ``` Replace *`your-db-name`**, **`your-username`**, **`your-password`**, and **`your-db-endpoint.rds.amazonaws.com`* with actual values from your RDS instance. --- *Step 5: Run Database Migrations* Once the settings are updated, apply migrations to set up the database schema: ```bash python manage.py makemigrations python manage.py migrate ``` This will create necessary Django tables in **AWS RDS PostgreSQL**. --- *Step 6: Test the Connection* Run the Django development server: ```bash python manage.py runserver ``` If everything is set up correctly, Django should connect to your AWS RDS PostgreSQL database 🎉. To confirm, open *PostgreSQL CLI* and check if the tables are created: ```bash psql -h your-db-endpoint.rds.amazonaws.com -U your-username -d your-db-name ``` Then, run: ```sql SELECT datname FROM pg_database; \c your-db-name; \dt; ``` --- *Step 7: Secure Your Connection (Optional but Recommended)* 🔹 *Use environment variables* instead of hardcoding credentials in `settings.py`: ```python import os DATABASES = { 'default': { 'ENGINE': 'django.db.backends.postgresql', 'NAME': os.getenv('DB_NAME'), 'USER': os.getenv('DB_USER'), 'PASSWORD': os.getenv('DB_PASSWORD'), 'HOST': os.getenv('DB_HOST'), 'PORT': '5432', } } ``` Then, store credentials in a `.env` file: ``` DB_NAME=your-db-name DB_USER=your-username DB_PASSWORD=your-password DB_HOST=your-db-endpoint.rds.amazonaws.com ``` Use *python-dotenv* to load them: ```bash pip install python-dotenv ``` And add this to `settings.py`: ```python from dotenv import load_dotenv load_dotenv() ``` --- #Django #AWS #PostgreSQL #AWSRDS #DjangoAWS #CloudComputing #WebDevelopment #Python #Database #DjangoPostgres #AWSCloud #DjangoTutorial
