Fedora/Centos ipxe bootscripts.

Been spending time looking at booting systems to the net to install linux operating systems. So far we have looked at Arch and Debian based systems. Both Fedora and Centos have pre-made iso's for network install.




Centos:

http://www.centos.org/download/

Fedora:

http://fedoraproject.org/en/get-fedora

But if you want to roll your own, here are some scripts to look at:

Fedora

 #!ipxe
  dhcp any
  # Set source URI
  set mirror http://download.fedoraproject.org/pub/fedora/linux/releases/20
 
  # Detect CPU architecture and calculate repository URI
  set arch i386
  set repo ${mirror}/Fedora/${arch}/os
 
  # Start installer
  kernel ${repo}/images/pxeboot/vmlinuz initrd=initrd.img repo=${repo}
  initrd ${repo}/images/pxeboot/initrd.img
  boot

or

  #!ipxe
  dhcp any
  # Set source URI
  set mirror http://download.fedoraproject.org/pub/fedora/linux/releases/18
 
  # Detect CPU architecture and calculate repository URI
  cpuid --ext 29 && set arch x86_64 || set arch i386
  set repo ${mirror}/Fedora/${arch}/os
 
  # Start installer
  kernel ${repo}/images/pxeboot/vmlinuz initrd=initrd.img repo=${repo}
  initrd ${repo}/images/pxeboot/initrd.img
  boot

or older releases




#!ipxe
  dhcp any
  # Set source URI
  set mirror http://archives.fedoraproject.org/pub/archive/fedora/linux/releases/14

  # Detect CPU architecture and calculate repository URI
  set arch i386
  set repo ${mirror}/Fedora/${arch}/os

  # Start installer
  kernel ${repo}/images/pxeboot/vmlinuz initrd=initrd.img repo=${repo}
  initrd ${repo}/images/pxeboot/initrd.img
  boot

----------------------------------------------



Centos

  dhcp any
  set base http://mirror.centos.org/centos/6/os/x86_64
  kernel ${base}/images/pxeboot/vmlinuz stage2=${base}/images/install.img ksdevice=${netX/mac}
  initrd ${base}/images/pxeboot/initrd.img
  boot

=================================

Our local server ipxe script

 #!ipxe
  dhcp any
  set base http://oeorgan1/distro/centos
  kernel ${base}/pxeboot/vmlinuz stage2=${base}/install.img ksdevice=${netX/mac}
  initrd ${base}/pxeboot/initrd.img
  boot


Files for local server needed:

${base}/
      boot.iso
      install.img
${base}/pxeboot/
     initrd.img
     vmlinuz

You actually can do a minimal windowing from the command line in Linux with dvtm. Dvtm is excellent for low end machines where graphics are not a priority. In the picture shown we have a working clock, SC a spreadsheet that you can easily export data to your favorite desktop spreadsheet such as Libreoffice, Links2 a web browser pointed to www.google.com, and finally nano a pretty decent basic text editor. I prefer vim, but nano has more of a user interface. Cheatsheet: `dvtm` is one simple, easy-to-use terminal multiplexer. Commonly used Options:     -v         prints version information to standard output, then exits.         -m <mod>   set default modifier at runtime.         [cmd...]   Execute cmd after dvtm is started. KeyBoard Shortcuts:     Mod    Each keybinding begins with Mod which defaults to ^g but can  be               changed in config.h or with the -m command line option.                       Mod-c  Create a new shell window.            Mod-x  Cl

Raspberry pi zero.

Instead of getting the rpi zero w, I will just add a usb female to my existing pi for the time being.Have lots of leftover cables for the cause.. Can always plug in a wifi or bluetooth module.   Various notes: Simplest configuration to connect to an unsecured wireless router knowing it;s essid: #linux auto lo iface lo inet loopback auto eth0 iface eth0 inet dhcp allow-hotplug wlan0 auto wlan0 iface wlan0 inet dhcp wireless-essid router-essid  Improvisational solder less header pin for the rpi zero Original pi zero fully decked out. with bluetooth, wired m and wireless. Basic setup ----------------- install jessie os do updates install vim mc Wifi ------ Check Ethernet & Wifi Before continuing make sure the Ethernet cable is connected in and you can ping out from the Pi: ping 8.8.8.8 You will also want to set up your WiFi dongle. runsudo shutdown -h now and then plug in the WiFi module when the Pi is off so you don't cause a
