Dependencies

Debian / Ubuntu and derivatives

On a fresh Debian/Ubuntu, as root user, install basic utility programs needed for the installation

sudo apt install curl sudo unzip vim

It would be wise to disable root access and to continue this tutorial with a user with sudoers group access
Install certbot (choose instructions for nginx and your distribution): https://certbot.eff.org/all-instructions
Install NodeJS 10.x (current LTS): https://nodejs.org/en/download/package-manager/#debian-and-ubuntu-based-linux-distributions
Install yarn, and be sure to have a recent version: https://yarnpkg.com/en/docs/install#linux-tab
Install Erlang and Elixir: https://elixir-lang.org/install.html#unix-and-unix-like
Install PostGIS: https://postgis.net/install/
Run:

sudo apt update
sudo apt install nginx postgresql postgresql-contrib openssl make git esl-erlang elixir postgis

Now that dependencies are installed, before running Mobilizon you should start PostgreSQL:

sudo systemctl start postgresql

sudo pacman -S nodejs postgresql openssl git wget unzip base-devel yarn nginx elixir postgis

Now that dependencies are installed, before running Mobilizon you should start PostgreSQL and Redis:

sudo systemctl start postgresql
