              Initial Server Setup with Ubuntu 14.04.md
            
          
    $local = operations launched in the local machine
$server = operations launched in the vps

1. Create a New User
$server adduser example_user

and add the relative Bedrock installation sudoer passwords
2. Root Privileges
$server gpasswd -a example_user sudo

3. Add Public Key Authentication (Recommended)
$local ssh-keygen
$local cat ~/.ssh/id_rsa.pub

$server mkdir /home/example_user/.ssh
$server chmod 700 /home/example_user/.ssh
$server vi home/example_user/.ssh/authorized_keys

and paste your public_key content to the authorized_keys file.
4. Add the right permission to the newly created user
visudo

Comment all existing user/group grant lines and add:
root    ALL=(ALL) ALL
example_user  ALL=(ALL) ALL

The above grants sudo access to the example_user user when they enter the proper password.
5. Configure SSH Daemon
$server nano /etc/ssh/sshd_config

and change the following line :
PermitRootLogin yes --> PermitRootLogin no 
PasswordAuthentication yes --> PasswordAuthentication yes

6. Reload ssh
$server service ssh restart
