  • updated install instructions
https://github.com/XSCE/xsce/wiki/XSCE-Installation
http://wiki.laptop.org/go/XS_Community_Edition/6.0

XSCE 6.0 Release Candidate 1 for CentOS “7.1”

  • this section updated Dec 30, 2015

Download 1.8GB XSCE 6.0 Release Candidate 1 for CentOS “7.1” (November 2015)

  • Download centos7_xsce.6.rc1.img
http://download.unleashkids.org/xsce/downloads/installer/centos/centos7_xsce.6.rc1.img

Follow instructions here: (Option 1.5)

http://wiki.sugarlabs.org/images/a/a4/IntelNUCInstallation-XSCEIIABServer.pdf

System Setup

  • Configuration I used for this testing
satellit
  • NOTE NUC i3 has 4 GB memory and wifi internal card installed.
intel (tm) NUC kit D34010WYKH1
1 TB Seagate HD added to empty kit
  • update: 02/18/2016
yum -y update
NUC 5 with 2 TB HD
xfce and firefox
- 552 rpms
centos-xovis

Also See

  • Google Docs with relevant info
http://wiki.laptop.org/go/XS_Community_Edition/FAQ#Is_a_quick_installation_possible.3F
https://docs.google.com/document/d/1Ez1H2LYrkqeXR_r5T93CMdmx9CeTJp_vC-IDBGam1Bc/edit#heading=h.hr9kca62zrfq

Configuration

  • Connect a USB­to­Ethernet dongle (adapter) from the NUC to a live Ethernet cable (with

live Internet) so that during installation, software can download and update itself. ​

  • Ideally, this live Ethernet wire leads from the dongle to a LAN port in the Netgear 3G

Modem/Router, whose WAN port (during this installation only!) leads to the Internet. Later you’ll verify “ping 8.8.8.8” and “ping mit.edu” works thru this wire, as will be discussed below.

  • Connect an Ethernet cable and a powered TP­LINK AP ​
(LAN port, and tape over WAN port to make sure it’s never used)​

to the NUC’s Ethernet port (its green link lights should light).

Install onto Intel NUC

  • This also works on a system 76 i7 laptop
  • Write to a USB stick with dd or gnome-disks restore
  • Windows users can use ​
http://sourceforge.net/projects/win32diskimager/

Format of HD for install

  • Do not use GPT format
Testing seems to result in all of installed content to be limited to 500 MiB
  • Format HD as fat ext4 in gnome-disks or gparted
Hint use booted f23 workstation live DVD or USB to access disks to reformat the internal HD.
exit live
then do install with dd USB of centos

Boot NUC with USB stick inserted, using F10 is necessary

  • NOTE USB port on NUC or Laptop where TP-Link is connected must be marked and be the only port used.
Or the server will not communicate with XO's or laptops
  • Type “erase” when requested
  • Watch for “done!” or #prompt; ignore “I/O error”.
  • Run “reboot”
Optionally Disable all USB booting in BIOS: F2 on Boot ­> Boot Configuration ­>

Boot Devices ­> USB

Likewise this should already be disabled: Boot ­> Boot Configuration ­> UEFI Boot ­> Boot USB Devices First

Login to your new server as: root / centos, then change both passwords: 

passwd                      (changes root password) 
passwd xsce-­admin           (has sudo powers, careful!)
  • Verify that you have internet connection with “ping yahoo.com”
Ensure both your networking connections are live and connected in their final position.
  • Update Centos7
yum update

Get the most recent version of the XSCE playbook 

cd /opt/schoolserver/xsce
git pull
./install-console
  • Reboot
Login to xsce-admin/(password)
sudo yum groupinstall xfce --skip-broken
sudo install firefox
startxsfce4
  • start firefox
  • Test client machines can reach ​
http://schoolserver.lan

or ​ 

http://172.18.96.1
  • Finally, if you have no downstream WiFi AP, try:
http://localhost

from any browser, on the server itself if available! And also try: 

http://localhost/admin​

with username “xsce-­admin” and the password you set above.

  • Alternate:

Log into the Admin Console (click on “Admin Console” link, user: xsce-­admin and the password you set above)

  • Select the services you want to install within "Configure­­ services".
Save configuration (green button)
Install Configured options (red button)
The TeamViewer service will automatically install a graphical environment.

Screenshot of Browse Activity 1.png

Launch TeamViewer from top­left "Applications Menu" > Internet > TeamViewer 10

  • Go to and select at bottom page"Configure Each service to Enable/Services Enabled" (in schoolserver/admin/)

Caution for learning only -- traditionally X Windows (graphical environment such as xfce, likewise TeamViewer running within it) should not be intalled on servers, in general.

  • Configure “Setup unattended access...” under TeamViewer’s Connection menu If You Dare.
  • Separately, OpenVPN can also allow remote diagnosis and support (over lower-bandidth connections, without the live visual mentoring/screensharing aspects of TeamViewer of course!)

Install your favorite text editor

For example, run: 

yum install emacs

Install GNOME Desktop

yum groupinstall 'GNOME Desktop'
  • Works well in centos7
Installed 12/18/2015 satellit
http://linuxconfig.org/how-to-install-gui-gnome-on-centos-7-linux-system

Install Xfce

If you must have a graphical environment on your server, run:
yum groupinstall xfce

Install browser, at your own risk

Install your favorite browser IF YOU UNDERSTAND ITS INHERENT RISKS TO DESTROYING YOUR SERVER. For example:
yum install firefox

Start the Xfce desktop

startxfce4

To make Xfce start at default boot

cd /etc/systemd/system 
ln -­sf /lib/systemd/system/graphical.target default.target
If above line fails, run
unlink default.target
then retry above "ln" command.
  • Reboot to test graphical login, presumably with username: xsce-­admin

Browsing rachel on centos 7.1 xsce

In the centos 7.1 xsce install (which has rachel installed) and logged into the wireless AP Internet in a Box from my T-400 laptop where I have cinnamon 2.6.12 desktop installed in Ubuntu 14.04 /sugar 0.106 

http://people.sugarlabs.org/quozl/ubuntu/trusty/sugar-0.106/olpc-ubuntu-sugar-14.04.2-desktop-amd64-1436317817.iso

Start firefox and point it to 

http://schoolserver.lan/xs-portal

which has a rachel entry under wikipedia (Interesting things. menu)

  • Here I can see the videos from kahn; Medline; Hesperian; Kahn health and Medicine; Project gutenburg etc....all mp4 files work
  • from ubuntu 14.04 on laptop ($100 rebuilt T400)
  • Videos are not available using an XO-1.5 software build 13.2.5, but I can see rest of content on the XO that does not use mp4.
  • Of course. No need to mention that here, as it is a known problem with OLPC OS. Why not test with restricted software loaded? You can do that with instructions for adding codecs, or by using a build with restricted software already included. You can contact me by mail for access to that build, as it is not public. --Quozl (talk) 20:00, 10 December 2015 (EST)

Meeting Notes 03/31/2016

"6th gen i3 NUC preliminary viability report from George -- does $249 @ http://frys.com/product/8732571 appear worth it for the masses in coming months? Short answer: YES, Amazingly considering all the complaints on Intel’s support wiki etc, this now appears extremely stable so far! Longer answer evolving... Install bios 0039.BIO before you do anything! Context: http://nucblog.net/2016/03/bios-version-0039-for-skylake-nucs/ AC8260 WiFi is soldered into these NUC6i3SYH & NUC6i3SYK require Linux kernel 4.1+; how can this possibly work with CentOS 7.2+? Somehow it does..."

F21-server-netinstall with xfce

NUC with 1 TB HD
  • Install on 32bit or 64bit Intel Machines

"The tried and true option is to start with a netinstall of the current OS, detailed as "option 1" below, and gradually build the machine up from offline downloads":

Start with an install of the base OS based upon your hardware:
http://download.fedoraproject.org/pub/fedora/linux/releases/21/Server/x86_64/iso/Fedora-Server-netinst-x86_64-21.iso
http://download.fedoraproject.org/pub/fedora/linux/releases/21/Server/i386/iso/Fedora-Server-netinst-i386-21.iso
Copy the downloaded iso to a USB stick (use dd in linux, or UNetbootin in windows)

Kickstart files

https://github.com/XSCE/xsce/tree/master/installer
For Live CD remixes + installers
https://raw.githubusercontent.com/XSCE/xsce/master/installer/netinstall/Fedora-21/install.ks
  • Add install.ks to root of USB
  • Hit tab when USB boots
Should do the following install automatically
NOT tested...
  • jvonau>: 02/01/2016
You need to use the label name of the usbkey.. to get the label ls '/dev/disk/by-label/ "
then use inst.ks=hd:LABEL=<what was returned above>:/install.ks
of if you know the what the device will be call then you could try: inst.ks=hd:sdb1:/install.ks
"inst.ks=hd:sdb1:/install.ks "
inst.ks=hd: sdb1: /install.ks no spaces
inst.ks=hd:LABEL= SOMENAME: /install.ks no spaces

Various OS Kickstart files and info

https://github.com/XSCE/xsce/tree/master/installer/netinstall

Option 1 (modified)

Start with an install of the base OS based upon your hardware:
http://download.fedoraproject.org/pub/fedora/linux/releases/21/Server/x86_64/iso/Fedora-Server-netinst-x86_64-21.iso
http://download.fedoraproject.org/pub/fedora/linux/releases/21/Server/i386/iso/Fedora-Server-netinst-i386-21.iso
Copy the downloaded iso to a USB stick (use dd in linux, or UNetbootin in windows)
  • The installer is somewhat obscure:
The first screen asks you to select keyboard and language
The next screen is the home page; you will click on topics, go off make to selections, and then return by clicking done.
  • Select "system"-installation destination:
Device selection, click on hard disk, click checkbox for "I will configure partitioning", click done.
  • In the left side window, under the drop down box, click <any previous OS> (unless the disk is already clean)
Click on the minus (which deletes the selected partition), select the "delete all other filesystems in .. as well"
Then select the drop down option "standard partition" and click the "install automatically" button
Delete the /home partition and add the resulting space to /
Otherwise the /library/downloads directory is only 53.7 GB and fills up when trying to install rachel
modify the file type to ext2 for all remaining partitions; update with right bottom button
Click the done twice, and the accept changes
  • Click on software selection, and xfce desktop
in right pane:
xfce extras; Admin tools; Devel Tools; Headless; system tools.
  • Then click start install
You will need to put in a password for root during the install.
DO NOT add a user as the ansible run later will add xsce-admin as user.
At the end of the install, a button will appear, which asks you to reboot into the newly installed Operating System.
Once you have logged in:, the steps are pretty straight forward:

In terminal: 

ping yahoo.com (this verifies that the server is properly connected to internet after the reboot) 
yum -y install icecat (or firefox)
  • NOTE: There is no need to do a
yum -y update
As the netinstall installs the latest files from the repo.
  • Connect the wifi unit to the adapter that will be used as the local area network (LAN), and make sure everything is under power with link lights.
  • Issue the following commands:
           yum -y install git ansible
           cd /opt
           mkdir -p schoolserver
           cd schoolserver
           git clone https://github.com/XSCE/xsce
           cd xsce
           ./install-console
           reboot
  • log in as root and add a password for xsce-admin
passwd xsce-admin
  • login as xsce-admin
  • I find it helpful to check that all the services are running on the server:
           syscemctl status NetworkManager
           systemctl status dhcpd
           systemctl status named
           ip addr (verify that the external adapter and the LAN adapter or br0 have ip addresses)
  • At this point you can connect to the server via the wifi at http://schoolserver/admin. Or with IceCat (firefox) from xfce desktop
Decide which services need to be enabled, check the checkboxes, Save Configuration, and click "Install configured Options'.
Wait for "SUCCEEDED" in Utilities/Display job status.
Next Install Content needed for rachel, kiwix, and/or other instructional materials.
Note: Get Rachel only appears On Install Content if you checked the rachel check box in Configure services
There are instruction for how and where to place the downloaded materials in README files in each of the roles folders.

F22-XSCE-LIVE

NOTE login to root of booted live; hit return no password to get to # prompt

run "xsceinst" to start the text installer
use installer to set your root password but please do not use "xsce-admin" as a new user, that one is already taken.

Download new installer with graphical installer

2-) log in to xsce-admin and get rachel. Should unzip and install rachel.
Saves redownloading of 21.2 GB file

Fix rachel CRC error

  • Tim Moody 12/11/2015
the rachel problem corrects itself the second time you take the option. the screen should say this.
if it doesn't you don't have the latest version.
when doing an install from an image do you make sure you have the latest fixes by doing the following?
cd /opt/schoolserver/xsce
git pull
./install-console

Fix "get rachel"

"get rachel" on xo1.5_20151224.img has bad address: links have changed
needs
http://rachelfriends.org/downloads/public_ftp/rachelusb_32EN/rachelusb_32EN_3.1.5.zip
now uses: http://rachelfriends.org/rachelusb_32EN_3.1.5.zip (Not accessable)
  • Tim Moody 01/15/2016:
easiest way to patch is to edit /opt/schoolserver/xsce/var/local_vars.yml
add the line
rachel_src_url: http://rachelfriends.org/downloads/public_ftp/rachelusb_32EN/rachelusb_32EN_3.1.5.zip
this will fix any future ansible run and change it in
/etc/xsce/xsce.ini
this will cause the console to have the correct address
