Install Source Package

If installing from the el7 source, replace el8 with el7 below. Change the installation prefix as desired. The default installation prefix is /usr/local/xdmod. These instructions assume you are installing Open XDMoD in /opt/xdmod.

# tar zxvf xdmod-10.5.0-el8.tar.gz
# cd xdmod-10.5.0
# ./install --prefix=/opt/xdmod

Create Open XDMoD User And Group

For improved security, create an Open XDMoD user and group that will have access to sensitive data:

# groupadd -r xdmod
# useradd -r -M -c "Open XDMoD" -g xdmod -d /opt/xdmod/lib -s /sbin/nologin xdmod

Secure the file containing database passwords:

# chmod 440 /opt/xdmod/etc/portal_settings.ini
# chown apache:xdmod /opt/xdmod/etc/portal_settings.ini

NOTE: The portal_settings.ini file must be readable by Apache and any user that will run the Open XDMoD commands. Replace the Apache username (apache) with the appropriate name if it is different on your system.

Add any user that will run Open XDMoD to the xdmod group:

# usermod -a -G xdmod jdoe

Replace jdoe with an appropriate username. Typically, you will need to log out of your system and log back in for this change to take effect.

Update log directory and file ownership and permissions:

# chmod 770 /opt/xdmod/logs
# chown apache:xdmod /opt/xdmod/logs
# touch /opt/xdmod/logs/exceptions.log
# chmod 660 /opt/xdmod/logs/exceptions.log
# chown apache:xdmod /opt/xdmod/logs/exceptions.log
# touch /opt/xdmod/logs/query.log
# chmod 660 /opt/xdmod/logs/query.log
# chown apache:xdmod /opt/xdmod/logs/query.log

The exceptions.log and query.log may be written to by both Apache and Open XDMoD commands.

Update the bin directory permissions so that only users with the xdmod group can run Open XDMoD commands:

# chmod 750 /opt/xdmod/bin/*

Run Configuration Script

# /opt/xdmod/bin/xdmod-setup

Complete each setup section with the required information.

See the Configuration Guide for more details.

Copy Configuration Files

# cp /opt/xdmod/share/templates/apache.conf /etc/apache2/conf.d/xdmod.conf

# cp /opt/xdmod/etc/cron.d/xdmod /etc/cron.d/xdmod

# cp /opt/xdmod/etc/logrotate.d/xdmod /etc/logrotate.d/xdmod

The directories where these files are needed may differ depending on your operating system.

The Apache configuration file is an example template. This template will need to be edited to specify site-specific parameters such as the SSL certificate paths and server name. See the Apache Configuration Guide for details.

Shred Data

Depending on which resource manager you use, your accounting logs may be stored in a single file, a directory containing multiple files or in a database that is queried using a specific command. Each of these is handled with different options in Open XDMoD.

See the Shredder Guide and the resource manager notes for more details.

PBS stores its accounting logs in a directory where the name of each file corresponds to the end date of the jobs it contains. A directory such as this can be specified using the -d option:

$ /opt/xdmod/bin/xdmod-shredder -v -r *resource* -f pbs \
      -d /var/spool/pbs/server_priv/accounting

SGE stores its accounting logs in a single file so the -i (input) option should be used:

$ /opt/xdmod/bin/xdmod-shredder -v -r *resource* -f sge \
      -i /var/lib/gridengine/default/common/accounting

Slurm stores its accounting logs in a database that can be queried using the sacct command. Since the accounting data is not directly accessible in files Open XDMoD provides a helper script that writes the data to a file and then shreds that file:

$ /opt/xdmod/bin/xdmod-slurm-helper -v -r *resource*

The resource name here must match the one supplied to the setup script.

NOTE: This command only works if Open XDMoD is on a machine with the sacct command or if you have configured your portal_settings.ini file with a command that accepts the same arguments as sacct (such as using ssh with a public key to run the command on another machine).

Ingest Data

$ /opt/xdmod/bin/xdmod-ingestor -v

See the Ingestor Guide for more details.

Restart Apache

# systemctl restart httpd.service

This command may be different depending on your operating system.
