This post will, quickly, run through how to create a Minimal Server Install using Ubuntu 16.04. It also only takes a short time, taking between 7 to 20 minutes to install depending on your hardware and the number of times you have run through it. I find it an ideal way to try out and learn how to install Ubuntu in various configurations. I also use a virtual machine running on Virtualbox as this allows me to throw it away without messing about with real hardware.
The virtualbox configuration I will be using is:
- Type: Linux
- Version: Ubuntu (64-bit)
- Memory Size: 1Gb
- Hard disk: 8Gb Dynamic
- Processor: 2
- Network: Bridged Adaptor
- Boot Source: ubuntu-16.06-server-amd.iso
I use a minimal Server Install as the basis of nearly all my guides as that is what I start out with use when creating new machines.
we will then have a known starting place and a good foundation when playing around with different installation types. It is generally simple to add extra functionality and services to it.
Choose the language you want to use for the installation GUI.
Then select that you want to install Ubuntu.
Choose the language that will be installed
Select your location
I select No at the Detect keyboard option as I am using a UK keyboard and it is simpler to select the options from the next few screens.
Add a host name, I tend to use a name to remind me what I an doing with the machine. So for this post I will use test-server.
Add a default user, I use fred as it is simple to type 🙂
Add a password for the user. Something simple as this is a test machine and we will mostlikly be typing it a lot while experimenting.
No point encrypting the users home director with this install. But something you could try out later on.
Set the time zone. This is the time zone you want to be displayed by the new server. For me it usually defaults to the right one. It is not the time zone it will use internally. Linux uses GMT/UTC for that by default.
Disk partitions. If this is not the fist time you are doing an installation on a disk you will see the next screen. The first time through it does not appear.
I normally use Guided – Use entire disk when experimenting. But this is an area you will want to spend some time playing around with and trying out different combinations. The two screen prints below show the differences between a new disk and a disk with an OS on already.
On the virtual disk I am using there is only one disk. So not much to do here.
Write the changes to the disk.
The next bit takes a minute or so to partition and format the disk and then install an initial boot system, before moving on to installing the actual software we want.
We will be installing from the iso or DVD so there will not be a HTTP proxy to configure.
What type of update are we going to allow the system to use.
Tnhe select the initial packages. I only select standard system utilities and OpenSSH server.. This gives the minimum you can use for most occasions and then just add the extra services or functionality as you require it using apt-get.
There is a longer pause here as the minimal server is installed and configured.
You will definitely want GRUB installed or your Minimal server install will not boot. 🙂
One more little pause while some services get configured. Then the installation is complete and ready to be booted the first time.
Once rebooted you can update ALL the software with the usual commands:
sudo apt-get update sudo apt-get dist-upgrade
The update will be pretty quick less than 5 minutes in all and it will update all the software to the latest in one go. There is No multiple checking and installing, configuring and rebooting.
That is all there is to a Minimal Server Install. It should use about 1.4 GB of the 8GB storage we allocated on the virtual machine. This is far quicker and simpler than installing Microsoft Windows. Windows can take hours to do the initial update 🙁
If you would like to convert this minimal server into a desktop with MATE. Just add the following:
sudo apt-get install mate-desktop-environment-extras mate-themes \ lightdm lightdm-gtk-greeter ubuntu-artwork update-manager
One last tweak and we can reboot. Create the lightdm config file /etc/lightdm/lightdm.conf with the following two lines under the heading [SeatDefaults]. This will give you a basic login/greeter for your desktop.
sudo nano /etc/lightdm/lightdm.conf
[SeatDefaults] greeter-session=lightdm-gtk-greeter user-session=mate
If you want to enable automatic logins for a user you can also add the lines that start auto login, adjust the
[SeatDefaults] greeter-session=lightdm-gtk-greeter user-session=mate autologin-user=
Once that is finished you can reboot and you will be presented with a graphical login prompt or automatically logged in depending on what you setup.
Fix for GVIM
If like me you also use gvim when you run it from the terminal you will see warning about a number of packages missing.
Gtk-Message: Failed to load module "gail" Gtk-Message: Failed to load module "atk-bridge" Gtk-Message: Failed to load module "topmenu-gtk-module"
You can remove these messages by installing the following:
sudo apt-get install libatk-adaptor libgail-common topmenu-gtk2 \ libtopmenu-client-gtk2-0 libtopmenu-server-gtk2-0 libtopmenu-client-gtk2-0 \ topmenu-gtk3 libtopmenu-client-gtk3-0 libtopmenu-server-gtk3-0 \ libtopmenu-client-gtk3-0
