Our web application relies heavily on the database for managing the individual records related to the users and the bugs that have been filed. For the demo application, we will set back with the PostgreSQL as the choice for our database. To install it on an RPM-based distribution, such as Fedora, the following command needs to be executed:

dnf install postgresql postgresql-server postgresql-devel

To install postgresql on any other distribution of Linux or any other operating system like Windows or Mac OS, the required commands for the distribution/OS will need to be executed.

Once we have the database installed, the next step is to initialize the database so that it can be used to store our application data. For setting up PostgreSQL, the following steps need to be executed:

sudo postgresql-setup –initdb –unit postgresql

This command helps to initialize the postgresql database server and start the server process. If no configuration has been changed, the server will default to listen to traffic on port 5432.

Once our server has been initialized, the next thing we need to do is to set up our database and the user that will be used by our BugZot application.

Now, let's switch our user to postgres and create the user and database. Once we have switched the user, the following commands need to be executed to create the required user and database:

psql
postgres=# CREATE ROLE bugzot_admin WITH LOGIN PASSWORD 'bugzotuser';
postgres=# CREATE DATABASE bugzot;
postgres=# GRANT ALL PRIVILEGES ON DATABASE bugzot TO bugzot_admin;

With this, we have our database up and running along with the required user and database that our application needs to connect to. From here on, we can work on our application directly without much of a manual interaction with the database.
