  autoconf 
  bison
  build-essential
  libssl-dev

sudo nano /etc/hostname   # ex: webserver.localdomain.com
sudo nano /etc/hosts      # change 127.0.0.1 webserver.localdomain webserver localhost4 localhost4.localdomain4

Create new user to deploy Rails app

# Create a new user called deploy
sudo adduser deploy --disabled-password   # --disabled-password only fur Ubuntu servers
sudo su - deploy                          # switch to deploy user

Give new user sudo power

sudo visudo                             # Open editor
deploy ALL=(ALL:ALL) NOPASSWD:ALL       # username ALL=(ALL:ALL) NOPASSWD:ALL
                                        # NOPASSWD:ALL option prevents password prompt when using sudo command

Create SSH key for deploy user

# On Local machine
ssh-keygen                            # press enter at password prompt for no password
                                      # Generates id_rsa and id_rsa.pub, copy id_rsa.pub

# On Server, while logged on as deploy user:
mkdir ~/.ssh && chmod 700 ~/.ssh
mkdir ~/.ssh/authorized_keys
chmod 600 ~/.ssh/authorized_keys
sudo vi ~/.ssh/authorized_keys        # Paste key into authorized_keys file
                                      # to edit: press 'i' then type/paste
                                      # to save/exit: press 'ESC' then ':x' then press enter

# SSH to server
# Plot in the values: ssh -i 'path-to-your-private-key' username@amazon-server-url
ssh -i 'id_rsa' deploy@ec2-xx-xxx-xxx-xxx.compute-1.amazonaws.com
