Throughout this book, we have mostly used the SQLite database. SQLite is simple and quick to set up, but for a production environment you will need a more powerful database, such as PostgreSQL, MySQL, or Oracle. You already learned how to install PostgreSQL and set up a PostgreSQL database in Chapter 3, Extending Your Blog Application. If you need to install PostgreSQL, you can read the Installing PostgreSQL section of Chapter 3, Extending Your Blog Application.

Let's create a PostgreSQL user. Open the shell and run the following commands to create a database user:

su postgres
createuser -dP educa

You will be prompted for a password and permissions you want to give to this user. Enter the desired password and permissions and then create a new database with the following command:

createdb -E utf8 -U educa educa

Then edit the settings/pro.py file and modify the DATABASES setting to make it look as follows:

DATABASES = {
   'default': {
       'ENGINE': 'django.db.backends.postgresql',
       'NAME': 'educa',
       'USER': 'educa',
       'PASSWORD': '*****',
   }
}

Replace the preceding data with the database name and credentials for the user you created. The new database is empty. Run the following command to apply all database migrations:

python manage.py migrate

Finally, create a superuser with the following command:

python manage.py createsuperuser
