Installing phoenix¶

The coure teaches phoenix v1.2 which can be installed by using the command

mix archive.install https://github.com/phoenixframework/archives/raw/master/phoenix_new-1.2.5.ez

The installation guide is available at https://hexdocs.pm/phoenix/installation.html.

Part from elixir, erlang and phoenix, we need node.js (>=5.0.0) too.

It can be installed using their website: https://nodejs.org/en/.

As the last step, we need to install PostgreSQL datatabase server, the course has a guide on how to install it directly on the machine.

I will be using docker for this.

docker run --name postgres -p 5432:5432 -e POSTGRES_PASSWORD=postgres -d postgres:11-alpine

Now you can connect on localhost:5432 using user postgres and password postgres.
