LOGO Linux Installation

Linux Distribution Including shells, libraries, tools, compiler, servers, applications. Redhat, Fedora, Mandrake, SuSE, Debian, Ubuntu, Gentoo… Live CDs You can make your own Linux distribution. This slide is based on Ubuntu

Before Installation Modify the boot sequence to boot your computer from CD-ROM Make sure your hardware and device A clear head and relaxed mind Some drinks and food

Start

Disks and Partitions /dev/hda, /dev/hdb, /dev/hdc, … /dev/hda1, /dev/hda2, … /dev/sda, /dev/scd0, … Mount Points / /swap …

Partition Division Four methods Resize the partition and use freed space Erase entire disk Use the largest continuous free space Manually edit partition table Choose a proper one or edit it manually.

Partition Division (cont.)

Swap partition is usually twice as RAM when it is less than 1GB No more than four primary partition including root partition and swap partition If four isn’t enough, use extend partition Make sure all your mount points are correct

End of Installation After dividing partitions, you only need to click your mouse. After installation, reboot and enjoy your Linux! Installation by text mode is the same as graphic mode

LOGO Compiling Linux kernel

What is Linux Kernel? Kernel is the core of an operating system. Scheduler, task management, memory management, … You need to compile kernel source code to binary in order to run.

When Should We Compile Kernel? You don’t need to compile kernel after Linux installation to run. You can configure your Linux by compiling a new kernel. Add new feature, ex. patch kernel. Support new hardware. Disable functions you don’t need. Develop your own kernel. Etc.

Where to D/L Linux Kernel? Go to System/Administration/synaptic package Manager

What Does Kernel Version Mean? Naming using [ 主版本 ].[ 次版本 ].[ 修訂版本 ]-[ 附 版本 ]. Odd minor number is testing version. Even minor number is stable version.

Prepare Your Kernel Source Code 1.You need to be root to compile kernel  # sudo -i 2.Download the necessary tools #apt-get update # apt-get install kernel-package libncurses5-dev bzip2 automake libc6-dev build-essential 3. Go to System/Administration/synaptic package Manager or to get the kernel source code

Prepare Your Kernel Source Code Unzip kernel source code. cd /usr/src bzip2 -d linux-source-2.6.X.tar.bz2 tar -xvf linux-2.6.x.tar 1.Make the link “/usr/src/linux-source-2.x.x” to the kernel source directory. #ln –s linux -source -2.6.x linux #cd linux You may have many versions of Linux source codes

# cp /boot/config-`uname -r`./.config or #make config #make menuconfig #make xconfig Prepare Your Kernel Source Code

make config

make config(cont.) If you meet some problems. (SATA) Device Drivers ---> SCSI device support ---> SCSI device support SCSI disk support Device Drivers ---> SCSI device support ---> SCSI low-level drivers ---> [*] Serial ATA (SATA) support

Kernel Compilation 1.#make clean 2.#make bzImage 3.#make modules 4.#make modules_install 5.#make install 6.#mkinitramfs –o /boot/initrd.img-2.x.x

Booting using New Kernel-Grub Setup your boot manager. # vim /boot/grub/menu.lst Add the following section: title linux uuid 1444e9cd-9a3b-427b-8ac5-6948ba8eeac5 kernel /boot/vmlinuz root=UUID=1444e9cd-9a3b-427b- 8ac5-6948ba8eeac5 ro initrd /boot/initrd.img Reboot.
