Lab #1 Install Linux & How to Build Live CD Operating System Lab

Install Linux

Install Linux(1/6) • There are two methods to install and execute Linux. • Directly • Install with CD or DVD • By VM • Install Linux on a VM (Virtual Machine) • VM (Virtual Machine) • A virtual machine is software that creates a virtualized environment between the computer platform and its operating system.

Build Live CD

What is Live CD • Live CD is a simple and small operating system • Executed upon boot, without installation on a hard drive. • It saves a lot of time to install OS and save the space of HD. • When your OS has some mistakes that make your PC can not boot, we can use Live CD to save your important data. • We can build a Live CD which is easy to customise with the user's preferred applications. NCHU System & Network Lab

Live CD-Step1-1 • Live-cd tools RPM • Squashfs-tools and yum are needed by Live-cd tool • Squashfs is a file system for Live CD • yum install squashfs-tools • yum install yum • Get live-cd tools RPM • http://people.redhat.com/davidz/livecd/i386/ • Get and install livecd-tools-001-1.i386.rpm . • wget -c http://people.redhat.com/davidz/livecd/i386/livecd-tools-001-1.i386.rpm • rpm -ivh livecd-tools-001-1.i386.rpm NCHU System & Network Lab

Live CD-Step1-2 • livecd-creator commands • livecd-creator • No packages specified. usage: livecd-creator [--help] [--repo=<name1>,<url1> ...] [--repo=<name2>,<url2>] --package=<p1> [--package=<p2> ...] [--exclude-package=<e1>] --exclude-package=<e2> ...] [--base-on=<path-to-iso-file>] [--fslabel=<label>] • --help : Print usage and exit • --repo : Path to yum repository • --package : Include this package • --exclude-package : Exclude this package • --base-on : Add packages to an existing live CD iso9660 image • --fslabel : File system label (default: livecd-YYYYMMDD-HHMI) NCHU System & Network Lab

Live CD-Step2 • Create the local data storage of fedora core 6 • Get and install createrepo. • wget -c http://tqmcube.com/files/createrepo-0.4.3-5.1.noarch.rpm • rpm -ivh createrepo-0.4.3-5.1.noarch.rpm • Creating a local repository of core packages • mkdir –p /var/www/html/repo/core/ • cp <PATH TO RPMs> /var/www/html/repo/core/ • Can download form internet or fedora core 6 • createrepo /var/www/html/repo/core/ • It may need some time to copy. NCHU System & Network Lab

Live CD-Step3 • Createrepo • Creating a local repository of configuration packages • mkdir –p /root/Desktop/base_packages • cd /root/Desktop/base_packages • wget -c http://people.redhat.com/davidz/livecd/i386/fedora-livecd-6-1.i386.rpm • createrepo /root/Desktop/base_packages NCHU System & Network Lab

Live CD-Step4 • Creating a minimal Live CD • livecd-creator --repo=c6,file:///var/www/html/repo/core --package=bash --package=kernel --package=grub --repo=lcd6,file:///root/Desktop/base_packages --package=fedora-livecd --fslabel=Fedora-minimal-LiveCD NCHU System & Network Lab

Live CD with GNOME • Createrepo • Creating a local repository of configuration packages • mkdir –p /root/Desktop/newbase_packages • cd /root/Desktop/newbase_packages • wget -c http://people.redhat.com/davidz/livecd/i386/fedora-livecd-6-1.i386.rpm • wget -c http://people.redhat.com/davidz/livecd/i386/fedora-livecd-gnome-6-1.i386.rpm • wget -c http://people.redhat.com/davidz/livecd/i386/fedora-livecd-desktop-6-1.i386.rpm • createrepo /root/Desktop/newbase_packages NCHU System & Network Lab

Live CD with GNOME • fedora-livecd-gnome bases on fedora-base and with GNOME. • fedora-livecd-desktop bases on fedora-gnome and provides many api and other utilities for GNOME. NCHU System & Network Lab

Live CD with GNOME • livecd-creator --repo=c6,file:///var/www/html/repo/core --repo=lcd6,file:///root/Desktop/newbase_packages --package=fedora-livecd-gnome --repo=e6, http://download.fedora.redhat.com/pub/fedora/linux/extras/6/i386 --fslabel=My-Fedora-LiveCD-1 NCHU System & Network Lab

Adding New Packages to An Existing Live CD ISO • livecd-creator --repo=c6,file:///var/www/html/repo/core --base-on=old-live-cd.iso --package=package --fslabel=My-LiveCD-New NCHU System & Network Lab

Creating Custom Configuration Packages • fedora-livecd-gnome.conf • In fedora-livecd-gnome-6-1.i386.rpm • Extract Here • Modify etc/livecd/20-fedora-livecd-gnome.conf NCHU System & Network Lab

Creating New RPMs • Spec: • http://people.redhat.com/davidz/livecd/spec/fedora-livecd.spec • cd /usr/src/redhat/SOURCE • Put all .config and file inside • rpmbuild -bb fedora-livecd.spec • ls /usr/src/redhat/RPMS/i386 NCHU System & Network Lab

How to Use USB Disk to Boot • Modify the fedora live cd iso that we did. • Step1: • Format usb disk, and let it’s file system be FAT32 • Step2 • syslinux /dev/sda1 • mount /dev/sda1 /mountpoint //mount usb • Step3 • mount /dev/hdc /mnt/cdrom //mount iso • cp -Rpf /mnt/cdrom/* /mountpoint • Step4 • cp -Rpf /mnt/cdrom/* /mountpoint • Change the file names • isolinux.bin =>syslinux.bin • isolinux.cfg=>syslinux.cfg NCHU System & Network Lab
