Installing Ubuntu Server

Installing the Ubuntu Server Edition using a Startup USB or Disc

The Ubuntu Server installer is text based and is more complex than a desktop install, due to all the available options. The good news is that, if you accept all the defaults, it will normally be straightforward and quick.

Assuming you have created a startup USB or CD, then installing Ubuntu Server is a case of putting the USB drive into a free USB port on the server / putting the CD into the CD drive, then doing the following:

  • Make sure the CD Drive/USB drive is the highest priority boot device (-see the Restarting using the Boot Disc section for details on how to do this)

  • The Ubuntu loader should start - pick "Install Ubuntu Server":

    Choose Install Ubuntu Server

  • Choose the installation language you wish to use:

    Choose Installation Language

  • Choose the country the server is located in:

    Choose the country the server is in

  • Either choose your keyboard layout -or have Ubuntu try and work it out from asking you a series of questions about it:

    Choose the keyboard layout

  • The base server installation will begin:

    Copying Additional Components Progress

  • Ubuntu will then try and auto-detect your network setup (-make sure your internet connection is plugged in and up if you want this to work):

    Auto Detect Network Settings

  • If Ubuntu cannot contact your DHCP server -or the server is not yet on the network then:

    • Ubuntu will first let you know it couldn't detect the settings:

      Auto Detect Failure Message

    • After clicking "Continue" - choose to either:

      • configure it manually now, using screens in the installation wizard

      • If your server was not connected to the network, you can plug it in now and re-try the auto-detection

      • Skip network configuration and do this manually once the server is up and running (-note: this is the option shown in the screenshot below)

      Choose Manual Network Configuration

  • Enter the hostname for the system (-it can always be altered later):

    Enter Hostname

  • If you have any discs on your server set up on a RAID Controller, then Ubuntu will pick this up and ask if you want these activated. The current advice is actually to remove the discs from the RAID controller and instead set them up as a Linux Software RAID array instead, so select "No" here:

    RAID Support

  • Select the disc that you want to put the Operating System on (-in the example, there is only one available):

    Selecting O/S Disc

  • Configure the discs how you desire, then select "Write the changes to disks". For details of the filesystems you need to create (-and recommended sizes), see the Desktop Installation section:

    Specifying Write Changes to Disc

  • Ubuntu will then create the filesystems as requested:

    Creating Filesystems

  • You will now be asked for the display name of the System Administrator (-it doesn't have to be a name - just something that you'll recognise):

    Enter Admin Display Name

  • Enter the name you want to use for the system admin account (e.g. fredb):

    Enter Admin Account Name

  • Enter a password for this account:

    Enter Admin Account Password

  • Re-enter the password for this account, to confirm it:

    Re-enter Admin Account Password

  • select if you require the user's /home directory to be encrypted (-e.g. if you plan to store sensitive data under it):

    Encrypt Home Directory?

  • The system will continue installing:

    Installation Progress

  • The system will then ask you if you want to automatically apply security updates. Your answer to this needs to consider your environment: if you have a large network where updates may break things, then you probably don't. If you have a fairly simple - or unattended server - that the System Administrator rarely logs onto, then automatic updates might be preferable:

    Select Patching Strategy

  • The install will continue, copying the appropriate files:

    Installation Progress Bar

  • You will then be asked if you want to install various optional components - select those you require (e.g. SSH, Samba, etc) by placing an asterisk next to them, before selecting "Continue":

    Select Optional Components to Install

  • You are then dumped into the "Aptitude" package manager - presumably to check what will be installed and any make changes if required:

    Aptitude package manager window

  • Quit "Aptitude" when you're ready to continue:

    Quitting Aptitude

  • The installation will copy the selected packages onto the system:

    Installation copies selected files

  • You'll be asked if you want to install the "GRUB" O/S loader as the default boot loader - as this is a Linux server (-no dual booting) - just accept this:

    Install GRUB as default boot loader

  • The installation will complete. Remove the startup disc/USB - then select "Continue" to reboot the server:

    Remove the USB startup disc and answer reboot prompt

  • If all went well, you should see the "login" prompt:

    Ubuntu 10.10 myServer tty1
    
    myServer login:
