Installation mirrors

By default DIANE is installed from http://cern.ch/diane website. Sometimes you may want to change this:

  • if you want to modify the DIANE software yourself then you must be sure that the modified version is picked up by the worker nodes
  • if you are in a cluster without outbound connectivity, you may set up internal web server and install DIANE from there

These are the instruction how to make DIANE installable from your own web server: http://my.web.server

Mirror the installation packages in my.web.server

On the my.web.server do:

diane-install --prefix=topdir VERSION

There is a topdir/packages local directory created. You should make this directory accessible to your web server via some URL. For example map topdir to http://my.web.server/diane

Installing master from my.web.server

On the master machine you may simply use:

diane-install --download-url=http://my.server/diane/packages VERSION

Enabling worker agents to use my.web.server

DIANE gets dynamically installed on the worker nodes. There is a small wrapper script which installs DIANE from http://cern.ch/diane and runs the WorkerAgent.

If you use Ganga to submit worker agents, then you should make sure the wrapper script will use http://my.web.server/diane rather than the default URL:

ganga LCGSubmitter.py --diane-download-url=http://my.web.server/diane/packages

If you don't want to repeat the --diane-download-url option every time then you may change the default URL in the run file:

def initialize_submitter(s):
	s.options.DOWNLOAD_URL="http://my.web.server/diane/packages"
