    BITS: Introduction to linux, distributions and installation BITS: Introduction to linux, distributions and installation Presentation Transcript

    • Dive into Linux
      • Introduction
      • Distributions
      • Installation
      BITS/VIB Bioinformatics Training – 3 oktober, 2011 – Joachim Jacob (archive: Luc Ducazu <luc@daphnia.com>) http://www.bits.vib.be/training
    • Who has used Linux?
    • What is Linux?
      • In a strict sense, Linux is a freely distributable, Unix-like operating system kernel (Linux kernel)
      • In a broader sense, Linux is a freely distributable, Unix-like operating system that includes a kernel, system tools, applications and a complete development environment (GNU/Linux distribution)
    • Linus Thorvalds
      • Student at the University of Helsinki, Finland in 1991
      • Inspired by Minix (Andrew Tanenbaum)
      • Started Linux as a simple UNIX-like OS on the Intel 80386 processor
      • Today Linus still decides what gets into the kernel and what not: Benevolent Dictator for Life .
    • Why should I bother?
      • Since Linux is
        • free (as in beer)
        • open (as in science)
        • user-friendly (depending on the definition)
      • it gets a lot of attention in academic circles
      • Linux is the preferred software development platform for eg NCBI
      • Linux drives innovation
    • Linux Distributions
      • A Linux Distribution ( Distro ) bundles:
        • the OS kernel (Linux)
        • tools and applications
        • software package manager
        • initialization & configuration scripts
        • commercial support
      • There are many distributions (600+), but only a few that really matter
      • http://www.distrowatch.com
    • 'Big' distributions
      • Red Hat:
        • RHEL http://www.redhat.com
        • Fedora http://fedoraproject.org
        • CentOS http://centos.org
      • Novell
        • SLES http://www.novell.com/linux/
        • openSuSE http://www.opensuse.org
      • Debian
        • Debian http://www.debian.org
        • Ubuntu http://www.ubuntu.com
    • http://nicolas.barcet.com/
    •  
    • Mini-distros
      • Live CD / DVDs: burn an .iso image to a CD and Linux starts from the CD without changing your system http://www.livecdlist.com
        • Recovery: SystemRescueCD http://www.sysresccd.org/
        • Bio-informatics: bioknoppix http://bioknoppix.hpcf.upr.edu/ biolinux http://nebc.nerc.ac.uk/nebc/tools/bio-linux
    • Mini-distros
      • A live CD / DVDs can also be written to a bootable USB stick using the Unetbootin http://unetbootin.sourceforge.net/
      • This tool is available for Linux and MS Windows
    • Distrowatch
      • Exhaustive collection of information on (Linux) distributions: http://distrowatch.com
      • Distro Popularity Statistics
      • 2011
        • (1) Ubuntu
        • (2) Fedora
        • (3) Mint
        • (4) openSuSE
        • (5) Debian
        • (14) CentOS
        • (24) RedHat
    • Linux Installation
      • Goal: desktop vs. server
      • Desktop: check whether your hardware
        • meets the system requirements
        • is supported
      • Obtain installation media on website of distro
      • Make sure you have some free disk space. (See later about installing next to or in Windows)
    • Supported Hardware
      • Do your home work
      • Hardware Compatibility List http://fedoraproject.org/wiki/HCL
      • Fedora 15 is in itself available as a live CD, this is a quick way to check what hardware is supported
    • Fedora 15
      • “ Bleeding Edge” distribution. Popular with Bioinformatics developers, latest, but potentially unstable.
      • http://fedoraproject.org
    • Fedora 15
      • “ Bleeding Edge” distribution. Popular with Bioinformatics developers, latest, but potentially unstable.
    • System requirements
      • Minimum system requirements for Fedora 15: http://docs.fedoraproject.org/en-US/Fedora/15/html/Release_Notes/sect-Release_Notes-Welcome_to_Fedora_15.html
        • CPU:
          • Pentium Pro @ 400MHz system
        • Memory:
          • Minimal 256 MB
          • Recommended for a graphical desktop 640 MB
          • Full graphical for graphical: 1152 MB
        • Disk space
          • Minimal 90 MB
          • Recommended 10 GB
    • Obtaining installation media
      • The most comprehensive page to start from is http://fedoraproject.org/en/get-fedora-all
        • Download CD or DVD iso-images using HTTP
        • Download torrent files for bittorrent downloads
      • Once the iso-images are downloaded
        • burn the images on CD or DVD
        • put the image on a USB stick ( UNetbootin )
    • Windows
      • If you want to install Linux next to MS Windows, there are a few alternatives:
        • Dual-boot : Windows and Linux on separate disk partitions
        • Run Linux in a virtual machine under MS Windows
        • Run Windows as a virtual machine under Linux
          • Virtual Box http://www.virtualbox.org/
      • For this session, we will run linux as a virtual machine on Windows.
    • Windows/Linux dual boot
      • With dual boot, upon start-up of your computer, you have the choice to start up linux OR windows
      • Windows occupies all disk space, you need to free up disk space
        • You should be aware that changing disk partitions is risky and can result in data loss – take a backup first
        • In Windows, defragment the drive(s)
        • Reduce the Windows partition – a handy tool is gparted , which can be launched from a live CD http://gparted.sourceforge.net/
      • For a Windows/Linux dual-boot installation you should install Windows first
    • Virtual linux
      • We will make use of VirtualBox, a software that can be installed on your computer and that allows you to install another OS in it. Alternatives: VMWare, KVM.

    • For example, on my laptop
