1.2 --- Configure Postgres User

PostgreSQL uses role for user authentication and authorization, it just like Unix-Style permissions. By default, PostgreSQL creates a new user called “postgres” for basic authentication. To use PostgreSQL, you need to login to the “postgres” account, you can do that by typing:

sudo su - postgres

And then change the password for postgres role by typing:

\password postgres

Then enter \q to leave the psql command line:


You can also use the sudo command to access the PostgreSQL prompt without switching users:

sudo -u postgres psql

1.3 --- Creating Postgres Role and Database

Create a new PostgreSQL Role named pi:

sudo su - postgres -c "createuser pi"

Create a new PostgreSQL Database named pidb:

sudo su - postgres -c "createdb pidb"

To grant permissions to the pi user on the pidb we created in the previous step, connect to the PostgreSQL shell, and run the following query:

sudo -u postgres psql
grant all privileges on database pidb to pi;

1.4 --- PostgreSQL config file paths


2.0 --- Install phppgAdmin

sudo apt-get install phppgadmin php7.2-pgsql

Note: for buster release you may have to install like this: sudo apt-get install -t buster phppgadmin php7.2-pgsql

2.1 --- Configure Apache

Edit the /etc/apache2/conf-available/phppgadmin.conf configuration file by typing:

sudo nano /etc/apache2/conf-available/phppgadmin.conf

Comment out the line #Require local and add below the line Require all granted so that you can access from your browser:

# Only allow connections from localhost:
#Require local
Require all granted

2.2 --- Configure phppgAdmin

Edit the /etc/phppgadmin/ configuration file by typing:

sudo nano /etc/phppgadmin/

Find the line '$conf['extra_login_security'] = true;' and change the value to 'false' so you can login to phpPgAdmin with user postgres:

$conf['extra_login_security'] = false;

Finaly we enable the configurations and restart services:

sudo a2enconf phppgadmin.conf
sudo systemctl restart postgresql
sudo systemctl restart apache2

You can now access phpPgAdmin with your browser
