LTSP Load Balancing Part One (Installation+Booting)

There are many Linux Flavors which provide easy and simple solution with  load-balancing upto ten Thin-clients on single server. For the specific conditions like more than one server and large number of thin-clients equipped labs we have to do some small tinkering with the configuration files. This is later part and I will describe it one the next part.

Available options are Edubuntu, Open-Suse(Kiwi), K12LTSP, and Skolelinux.

We will use Skolelinux for our purpose. It is better documented and well supportive.

 

First of all let me explain a very simple logic how Booting and Load-balancing happens between Linux server and Thin-clients.

Linux server+LTSP+DHCP = Complete [(Load-balancing) + (Fail-over) + (Thin-client boot)]

Basically DHCP works to boot thin-clients from the Linux server and LTSP decides what kind of applications+resources should be provided. To save all users data Open LDAP. (This is very much later)

Now first of all you have to download the ISO file from the link below. (It has 5.4 GB size)

http://ftp.skolelinux.org/skolelinux-cd/debian-edu-7.1+edu0-USB.iso

 Now you need to burn it on pendrive using the the following links.

http://unetbootin.sourceforge.net/

Unetbootin is the application to make bootable pendrive from ISO file.

Before starting the installation make sure your Ethernet card/cards should not be connected to LAN cable.

Start the installation.

There are various options to install and configure “Skoole Linux” but here I am providing simplest and best one. 🙂

In the following PDF to see the installation instructions please direct jump to Page No. 9. (You can read all the technical data explained in the page 1-8 but presently please follow my tutorial as is )

All the installation procedure is from page No. 20-28 should follow as described in the PDF.

In between the installation you may have problem with Partitioning you hard disk. I suggest to use the option “Use Entire Disk” only if you have nothing to lost on your hard-drive. Otherwise for advance Partitioning Scheme you the following link.

######################################################################################### 

After the installation completion connect your LAN cables as you normally do with windows setup and boot your server.

The same procedure has to be done for all of other three servers but I suggest to try it only one server first and let your Thin-client boot from it.

This is simple Thin-client booting from server. No load-balancing or other implementations has not been done yet. Let me know when you will be able to complete your work till this step and I will write the Second part which will Explain how to make one ROOT server ans other Three Application Servers.
