ROOT set up

The following should be performed as the root user

• Add Debian repositories as here

• Install ssh-server:

     1  apt-get update
     2  apt-get install openssh-server
     3  systemctl start ssh
  

• Install Apache (for web server):

     1  apt-get install apache2
     2  a2enmod userdir
     3  systemctl restart apache2
  

• 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:

     1  <IfModule mod_userdir.c>
     2  ...
     3      <Directory /home/*/public_html>
     4          AllowOverride FileInfo AuthConfig Limit Indexes AllowOverride
     5              ...
     6      </Directory>
     7  </IfModule>
  

• Add LIGO Debian repositories as here, and install keyring to trust:

     1  apt-get install lscsoft-archive-keyring
  

• Installed basic dependencies:

     1  apt-get install \
     2      git \
     3      python-pip \
     4      python-virtualenv \
     5      python-nds2-client \
     6      lal-python \
     7      ldas-tools-framecpp-python \
     8      python-gwpy \
     9      lalapps
  

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  python -m pip install \
     2      "gwpy>=0.12.0"
     3      git+https://github.com/gwpy/gwsumm.git
  

Automation setup

• Install HTCondor:

     1  apt-get install htcondor
  

Automation notes

The automation is handled using HTCondor's timescheduling system.

• If the Condor queue is empty, you need to restart the scheduled jobs:

     1  cd /home/controls/etc/summary/condor
     2  condor_submit gw_daily_summary_kagra.sub
     3  condor_submit gw_daily_summary_rerun_kagra.sub
  

  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

Monitoring setup

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 Installation

• Writer : TYamamoto

After the installation of gwpy and the daily-summary tools, TYo installed emacs.

> su 
> apt-get install emacs

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.

> su -
> apt-get install sudo nfs-common
> emacs -nw /etc/fstab
k1nfs0:/export/users       /users       nfs            rw,bg,soft  0 0
> mount -a
