Configuration

Note: Use minimal configuration files as discussed in http://github.com/jacobian/django-deployment-workshop

Initialise

Warning

Probably not a good idea to change the default location. Use Table Space instead!!

If you change the location of the data_directory, you will need to initialise the folder. To do this, I ran the following command:

sudo -i -u postgres
/usr/lib/postgresql/9.1/bin/initdb --locale=en_UK.UTF-8 --encoding=UNICODE -d /mnt/cbsvolume/postgresql/9.1/main/

Database

From Ubuntu, Community Documentation, PostgreSQL

To start off, we need to change the PostgreSQL postgres user password; we will not be able to access the server otherwise. As the postgres Linux user, we will execute the psql command:

sudo -u postgres psql postgres

Set a password for the “postgres” database role using the command:

\password postgres

For test purposes, I use the password postgres…

Log out of psql:

\q

Log into the default database (using the default postgres user):

sudo -u postgres psql

…or try:

psql postgres postgres

…or try:

su - postgres
psql

Create a user

SELECT * FROM pg_user;
CREATE USER patrick WITH PASSWORD 'password' CREATEDB;

(To delete a user, DROP USER patrick;)

Note: By default in Ubuntu, PostgreSQL is configured to use ident sameuser authentication for any connections from the same machine. Essentially this means that if your Ubuntu username is foo and you add foo as a PostgreSQL user then you can connect to the database without requiring a password.

Create a database (setting the user we just created as the owner):

CREATE DATABASE mynewdb OWNER patrick;

Log out of psql:

\q

Log into the new database with the new user:

psql mynewdb patrick
