A Poor Man’s Computer Cluster

by on Jan.25, 2009, under Solaris

This article is about my experiences with a project I had at work. I will describe the complete process I used to setup two Solaris 10 servers to be used as an FTP cluster. This article will be broken into several parts and will cover the following topics:

Part 1:

  • A complete description of the problem.
  • A proposed solution.
  • The hardware needed.
  • The software needed.
  • The network topology used.

Part 2

  • Setup of customized start up scripts with SMF.
  • Setting up SSH on a non standard port.
  • Setup and configuration of the software package Unison.
  • Passwordless SSL communication via an SSH key pair.
  • Writing a BASH shell script to syncronize system files and other data using unison over an SSL connection.

Part 3

  • How to use multipathing on Solaris 10 in order to failover a virtual IP address between two servers.
  • Writing BASH shell scripts that will detect network problems and fail a system over to the other system.

Part 4

  • Setup and configuration of ProFTPD.
  • Testing.
  • Final conclusions.
