Description
The "gridification" of a computing farm is usually a complex and time consuming task.
Operating system installation, grid specific software, configuration files
customization can turn into a large problem for site managers.
This poster introduces InGRID, a solution used to install and maintain grid software
on small/medium size computing farms.
Grid elements installation with InGRID consists in three steps.
In the first step nodes are installed using RedHat Kickstart, an installation
method that automate most of a Linux distribution installation, including disk
partitioning, boot loader configuration, network configuration, base package selection.
Grid specific software is than integrated using apt4rpm, a package management wrapper
over the rpm commands. Apt automatically manages packages dependencies, and is able
to download, install and upgrade RPMs from a central software repository.
Finally, grid configuration files are customized through LCFGng, a system to setup
and maintain Unix machines, that can configure many system files, execute scripts,
create users, etc.
