Creating Database Users for PostgreSQL for our projects.
I wanted to let you know, that it is a bit of a tricky process to connect to the PostGres backend as a user that is not postgres. Here are the steps that I did, to make it so I could connect as another user.
Backend
Be sure to remote into your backend database server using SSH, and perform the following steps.
ssh <YourUsername>@srv1.bcirpg.com
sudo nano /etc/postgresql/13/main/pg_hba.conf
Ensure that the bottom section of this file looks like this example below. The main thing that we are worried about, is turning on MD5 authentication. This will allow our new user accounts to sign in, using defined passwords.
# Put your actual configuration here
# ----------------------------------
#
# If you want to allow non-local connections, you need to add more
# "host" records. In that case you will also need to make PostgreSQL
# listen on a non-local interface via the listen_addresses
# configuration parameter, or via the -i or -h command line switches.
# DO NOT DISABLE!
# If you change this first entry you will need to make sure that the
# database superuser can access the database using some other method.
# Noninteractive access to all databases is required during automatic
# maintenance (custom daily cronjobs, replication, and similar tasks).
#
# Database administrative login by Unix domain socket
local all postgres peer
# TYPE DATABASE USER ADDRESS METHOD
# "local" is for Unix domain socket connections only
local all all md5
# IPv4 local connections:
host all all 127.0.0.1/32 md5
# IPv6 local connections:
host all all ::1/128 md5
# Allow replication connections from localhost, by a user with the
# replication privilege.
local replication all peer
host replication all 127.0.0.1/32 md5
host replication all ::1/128 md5
From there we can move on to creating the user.
Creating a new default user
Connecting to the database is impossible, without a new user. I am going to use Ernie as the example username.
Here are the commands that I ran to create a new user, that can be used by Godot's Postgres plugin.
sudo -u postgres createuser ernie
sudo -u postgres psql -d main
main=#
main=# ALTER USER ernie WITH PASSWORD 'yourpassword';
From there you can connect to the database using the following command. Be sure to connect using the same password that you used, when creating your "Ernie" user.
psql -h localhost -d main -U ernie
