= Installing NetBox on Ubuntu 20.04 =
NetBox requires PostgreSQL 10 or later. Please note that MySQL and other relational databases are not supported.

=== PostgreSQL Database Installation ===
{{{
# sudo apt update
# sudo apt install -y postgresql
}}}

Once PostgreSQL has been installed, start the service and enable it to run at boot:
{{{
# sudo systemctl start postgresql
# sudo systemctl enable postgresql
}}}

=== Database Creation ===
At a minimum, we need to create a database for NetBox and assign it a username and password for authentication. Start by invoking the PostgreSQL shell as the system Postgres user.
{{{
# sudo -u postgres psql
}}}

Within the shell, enter the following commands to create the database and user (role), substituting your own value for the password:
{{{
CREATE DATABASE netbox;
CREATE USER netbox WITH PASSWORD 'netbox123';
GRANT ALL PRIVILEGES ON DATABASE netbox TO netbox;
}}}
Do not use the password from the example. Choose a strong, random password to ensure secure database authentication for your NetBox installation.
