This article offers a simple introduction to PostgreSQL and how to install it. It is necessary for Tryton. In effect, this article is merely filler, and one can skip it if one wishes so.
PostgreSQL is an open-source ORDBMS which is a hardcore programmer’s paradise. Since it is community-developed, it adheres to strict standards and supports DB best practices. For more information, Google is your friend.
Now the installation of Postgres on your setup depends on the operating system you have installed. For most Linux distros, Postgres has a distro-specific bundle which can easily be installed using the particular package manager. It is usually advised to install this distro-specific bundle rather then going down the generic route.
I had faced several problems setting up Postgres on Linux Mint because I downloaded and executed the generic bundle. You can find some mention of those problems here at the wiki of a project which I wrote as part of a company induction task. I am currently on Lubuntu, and this time, I used the package manager. Lesson learned.
Another thing you ideally should do is install PGAdmin. It is a very useful tool for management and administration of your databases. You might often have to view a specific table inside the DB that you create for Tryton.
For Debian derivatives such as mine,
There is also the
postgres user setup. After one is done installing the above,
one should fire up a terminal and set the
postgres user’s password.
Equivalently, one could do
sudo su - postgres to get into the postgres account,
and then run
psql -u postgres -h localhost or something similar.
The second line in the above snippet sets a password for the postgres database
And that’s that. Soon, we shall be on a functioning Tryton setup!
