Ubuntu Server 16.04 OS Installation

This guide walks you through the steps necessary to install Ubuntu 16.04 LTS on a bare metal server.

  1. Create bootable USB Stick, following the tutorial available by Ubuntu, depending if your desktop is Windows, OSX or Ubuntu.

  2. Boot from USB device

  3. UNetbootin prompt: Select **"Install Ubuntu Server"

  4. Language: Who are we to say what language you want to set on your server…​ We just went for the boring option: "English"

  5. Country selection: Select your country (in our case "Other" ⇒ "Europe" ⇒ "Greece")

  6. Locale selection: en_US.UTF-8 locale selection

  7. Keyboard layout: "Yes" on auto-detect. Press keys as requested. (in our case, us:intl )

  8. Press "ok" on unetbooting warning. You can safely ignore.

  9. Hostname: You will need some kind of naming scheme. We used kube01 and increased numbering accordingly.

  10. Username: Please feel free to use ubuntu or whatever you prefer. We used k8s.

  11. Password: Select a secure password and make sure to store it somewhere safe. No, Post-its on your screen do not classify as "somewhere safe".

  12. Encrypt user home: "No". Disclaimer: clearly, there might be security considerations on your environment, which I’m not aware of. Make up your own mind, but my guide assumes you selected "No".

  13. Confirm Timezone: in my case it was correctly auto-detected as "Europe/Athens".

  14. Disk and partitions:

    • (Optional, e.g. in case the bare metal server was already used for something else) Unmount partitions that are in use: "Yes"

    • Guided ⇒ Use entire disk & setup LVM

    • Select appropriate disk

    • "Yes"

    • "50%" on LVM size

    • Finish Partitioning

    • Confirm by clicking "Yes"

  15. Proxy: leave blank, or enter http proxy, if appropriate (in my case blank).

  16. Security Updates: Again, this is a security consideration you will have to make on your own (I am by no means a security expert), but we did select: "Install security updates"

  17. Software selection:

    • ensure standard system utilities AND

    • OpenSSH server are both checked

  18. Patiently wait for software to be installed…​…​…​…​..

  19. Install the GRUB boot loader to the master boot record?

    • Select "Yes"

    • Select hard disk (not USB disk!) - usually /dev/sda - and press Enter.

  20. Remove USB disk and click "Continue".
