##Linux - Free as in Freedom

####Setting up a VM or repurposing an old machine

• Downloading/Getting an iso (I will have a few USB sticks with ISO's)
• Loading the machine (Spinning up a VM or setting the BIOS load order)
• Installing Ubuntu 15.04
• During install we will talk about different distro's

####Familiar place

• Bash based terminal

- Mission

The purpose of this tutorial is to mimic setting up a DigitalOcean/AWS EC2/Linode server. The main advantages of having a virtual machine is that you can learn without worry of breaking things.

The first lesson will be all about getting familiar with a headless machine and getting a language we all know and love (ruby). Then we can mess around and try things out purely in the terminal.

The only three good options for a text editor are: emacs, vi, and vim. We will be using vim but vi itself is great and comes by default on Ubuntu 12.04.

Now you can practice getting used to ssh'ing into headless machines, using terminal based text editors, and using a terminal based window/session manager (tmux). The reason we have to use vim and tmux is that there is no X environment in a headless machine (the GUI, graphics, pretty things, etc..). The main reason for this is to save space on precious costly SSD data.

To have PG accept user DB creation from mix ecto.create for Phoenix with PG installed from homebrew

    createuser postgres -d

then run

mix ecto.create

selfup

Now that we have ruby, node, and rails, it is time to get pg

    ssh root@your_ip_address_for_DO
    sudo apt-get update
    mkdir -p ~/.rbenv/plugins
    cd ~/.rbenv/plugins
    git clone https://github.com/sstephenson/rbenv-vars.git
    cd
    sudo apt-get install postgresql postgresql-contrib libpq-dev
