Installation of KAGRA summary pages
- Writer : Duncan
ROOT set up
The following should be performed as the root user
Add Debian repositories as here
- Install Apache (for web server):
To enable .htaccess files within the userdir configuration for Apache, the all option was added to the <Directory /home/*/public_html> AllowOverride directive as follows:
Add LIGO Debian repositories as here, and install keyring to trust:
1 apt-get install lscsoft-archive-keyring
- Installed basic dependencies:
Summary pages setup
The following is performed as the controls user
- Set up a virtualenv for the summary page code:
1 python -m virtualenv ~/opt/summary-2.7 --system-site-packages
- Activate the virtualenv to enter that environment:
1 source ~/opt/summary-2.7/bin/activate
- And then install everything we need:
1 apt-get install htcondor
The automation is handled using HTCondor's timescheduling system.
- If the Condor queue is empty, you need to restart the scheduled jobs:
these jobs will persist in the Condor queue. If the persistens jobs are held, you cannot condor_release them, you must condor_rm and condor_submit again. For any other jobs (gw_summary), condor_release works fine
I (Duncan) have installed Ganglia on k1sum0 to allow web-based monitoring of the CPU/memory/disk/network etc. This is achieved as follows:
- Install ganglia software:
1 apt-get install ganglia-monitor gmetad ganglia-webfrontend
- Link Ganglia Apache configuration and restart:
1 ln -s /etc/ganglia-webfrontend/apache.conf /etc/apache2/sites-enabled/ganglia.conf
- Edit configuration files to include some useful information:
/etc/ganglia/gmond.conf # edit cluster parameters around line 20 /etc/ganglia/gmetad.conf # edit gridname on line 72
- Restart all of the necessary services
1 systemctl restart ganglia-monitor gmetad apache2
The Ganglia output is viewable on http://k1sum0/ganglia/.
Ganglia is designed to monitor an entire cluster of machines; this page might be useful if you wish to add other machines to the Ganglia output.

After the installation of gwpy and the daily-summary tools, TY installed sudo and nfs-common. nfs-common is required we use nfs as the mount type on /etc/fstab.
