To set up your new server, execute the following commands.

Set the hostname

Set the server hostname. Any name will do — just make it memorable. In this example, I chose “future”.

echo "future" > /etc/hostname
hostname -F /etc/hostname

Let’s verify that it was set correctly:

hostname

Set the fully-qualified domain name

Set the FQDN of the server by making sure the following text is in the /etc/hosts file:

    127.0.0.1          localhost.localdomain   localhost
    127.0.1.1          ubuntu
    <your server ip>   future.<your domain>.net       future

It is useful if you add an A record that points from some domain you control (in this case I used “future.<your domain>.net”) to your server IP address. This way, you can easily reference the IP address of your server when you SSH into it, like so:

ssh future.<your domain>.net

If you’re curious, you can read more about the /etc/hosts file.

Set the time

Set the server timezone:

dpkg-reconfigure tzdata

Verify that the date is correct:

date

Update the server

Check for updates and install:

aptitude update
aptitude upgrade
