Setup Aurora PostgreSQL RDS in AWS [2 Steps]

In this article we are going to cover Setup Aurora PostgreSQL RDS in AWS and connect Aurora PostgreSQL RDS using EC2 Instance.

Prerequisite:

• AWS Account with Admin privileges

To create an Amazon Aurora PostgreSQL database, you can follow these steps:

Step #1:Sign in to the AWS Management Console

You’ll need an AWS account. If you don’t have one, you can sign up at AWS official site

Open the Amazon RDS Console

Once you’re signed in, go to the AWS Management Console and search for “RDS” in the AWS services search bar. Click on “Amazon RDS” to open the RDS dashboard.

Step #2:Setup Aurora PostgreSQL RDS in AWS

To Launch new Aurora PostgreSQL RDS in AWS, search RDS in AWS search box

In the RDS dashboard, click the “Create database” button.

Select the Database Engine:

Select “Amazon Aurora with PostgreSQL compatibility“

Specify DB Details:

Configure Advanced Settings Amazon Aurora with PostgreSQL

You can configure additional settings, such as VPC, subnet group, security groups, and database options. Adjust these settings according to your requirements.

Add Tags (Optional):

You can optionally add tags for easier management and cost allocation.

Review and Launch:

Review all your settings to ensure they are correct.

Create Database:

Click the “Create database” button to launch your Aurora PostgreSQL instance.

Monitor the Creation Process:

Wait for the database creation process to complete. You can monitor the progress on the RDS dashboard.

Once the database instance is created, you can connect to it using a PostgreSQL client or application. You’ll need the connection endpoint, username, and password that you specified during the setup.

Configure Security and Access:

Make sure to configure security groups and IAM roles to control who can access your Aurora PostgreSQL database.

Configure Backup and Maintenance:

Set up automated backups and maintenance windows to ensure the health and availability of your database.

Start Using Your Aurora PostgreSQL Database:

You can now start using your Aurora PostgreSQL database to store, retrieve, and manage your data.

Remember that Amazon Aurora is a managed database service, which means AWS takes care of many of the administrative tasks such as patching, backups, and high availability. Be sure to refer to the AWS documentation for more detailed information and best practices related to Amazon Aurora PostgreSQL.

Step #3:Connect to Aurora PostgreSQL Database using EC2 Instance

To connect to an Amazon Aurora PostgreSQL database using an Amazon EC2 instance, you can follow these general steps:

1. Launch an Amazon EC2 Instance:

• If you haven’t already, launch an Amazon EC2 instance that will act as your application server or client. Ensure it’s in the same VPC (Virtual Private Cloud) as your Aurora PostgreSQL database.

2.Install PostgreSQL Client:

• Connect to your EC2 instance using SSH and install the PostgreSQL client if it’s not already installed. You can use yum for Amazon Linux or apt-get for Ubuntu/Debian.

   # For Amazon Linux
   sudo yum install postgresql

   # For Ubuntu/Debian
   sudo apt-get install postgresql-client

3. Obtain Database Connection Information:

• Go to the AWS RDS dashboard, locate your Aurora PostgreSQL instance, and note down the following information:
  • Endpoint: This is the DNS address of your Aurora PostgreSQL instance.
  • Port: The default port for PostgreSQL is 5432.
  • Username: The username you set during database creation.
  • Password: The password you set during database creation.

4. Configure Security Groups:

• Ensure that your EC2 instance’s security group allows outbound traffic to the Aurora PostgreSQL instance’s security group on the PostgreSQL port (usually 5432). Similarly, the Aurora PostgreSQL security group should allow incoming traffic from the EC2 instance’s security group on port 5432.

5. Connect to the Database:

Use the psql command-line utility to connect to the Aurora PostgreSQL database from your EC2 instance. Replace the placeholders with your actual database information.

   psql -h your-database-endpoint -U your-username -d your-database-name -p 5432

• You’ll be prompted to enter the database password.

1. Perform Database Operations:

• Once connected, you can run SQL queries and perform database operations using the psql command-line tool.

1. Exit the psql Shell:

• To exit the psql shell, you can use the command:

   \q

Remember that it’s essential to handle sensitive information like database passwords securely and to apply best practices for database security, such as using IAM authentication if possible, for a more secure connection between your EC2 instance and Aurora PostgreSQL database.
