Note: This version of the VDT (1.2.0) is no longer supported. Feel free to look through the documentation and install it, but we cannot guarantee support for it. The current stable release is 2.0.0.

Condor Configuration Script

The new Condor installation/configuration script, condor_configure, simplifies the task of installing and re-configuring the Condor software that comes with VDT.

When installing the Condor package as part of VDT condor_configure will perform the following without asking user any questions:

Install Condor binaries and libraries into

   $VDT_LOCATION/condor

Create the local directory (Condor home directory)

   $VDT_LOCATION/condor/local.$HOSTNAME

Create global and local configuration files:

   $VDT_LOCATION/condor/etc/condor_config

   $VDT_LOCATION/condor/local.$HOSTNAME/condor_config.local

Modify the local configuration file to create a working personal Condor (i.e. a 1-machine pool with local central manager)

During the VDT install process condor_configure writes important messages to the VDT post-install README file ($VDT_LOCATION/post-install/README). It is a good idea to check it for messages about things that the script was not able to automatically configure, errors it encountered, etc.

After the initial installation the user may always re-run condor_configure from $VDT_LOCATION/condor directory to change certain important options such as setting the central manager, changing the running daemons, etc. In particular:

--make-personal-condor

Creates a personal Condor (i.e. a 1-node pool running on local machine).

--type=[submit],[execute],[manager]

Determines which role(s) the machine will perform in a pool (which translates to which daemons will run).

submit - allows the machine to submit jobs (enables condor_schedd). This option is appropriate for a Condor-G only machine.

execute - allows the machine to execute jobs (enables condor_startd)

manager - allows the machine to act as a central manager (enables condor_negotiator,condor_collector)

In the case of a personal Condor this value is automatically forced to be "submit,execute,manager".

--central-manager=host

Connect to a pool with central manager on host

--local-dir=local_dir

Sets the local directory (Condor home) to the specified directory. Moves the relevant Condor directories (log, spool, execute) there.

--owner=owner

Run Condor daemons as specified user (can be either ID or username). (Only applicable when condor_configure is run by root, otherwise the current user is assumed). Changes ownership of log,spool,execute directories to specified user, and instructs Condor system to run as that user (by setting CONDOR_IDS in the config file).

--verbose

Print detailed information about changes being made to configuration.

With the exception of the initial install the configuration script only makes changes to the local configuration file ($VDT_LOCATION/condor/local.$HOSTNAME/condor_config.local). When it does it backs up the old version of the config file by appeding a timestamp to it.
