Setting up a Postgres database

Last Updated on Wednesday 5th Oct 2022

Check if Postgres is installed on your computer

			
					psql --version

			
	

Otherwise, Install PostGres

  • Launch the Postgres console as the Postgres user
			
					sudo -u postgres -i
psql

			
	

or, in macOS:

			
					psql postgres

			
	

In the Postgres console, create a user and database for your application.

			
					CREATE DATABASE app_db;
CREATE USER app_db_user WITH ENCRYPTED PASSWORD 'password';
GRANT ALL PRIVILEGES ON DATABASE app_db TO app_db_user;

			
	

With Docker

			
					docker run --name postgres -e POSTGRES_PASSWORD = mysecretpassword -p 5432: 5432 -d postgres

			
	

(host: localhost, username: Postgres)
