Slurm-web Installation

Back to Job Scheduler Slurm

Slurm-web installation

First, let's review the prerequisites:

• python
• pyslurm (python module)
• Flask (python module)
• clusterShell (python module)
• bootstrap (javascript library)
• jQuery
• Flot (jQuery extension for graph drawing)

all python modules and javascript libraries ought to be installed via apt packages for the slurm-web installation to work

Installing prerequisites

Some previous packages:

aptitude install apache2-dev

aptitude install libapache2-mod-wsgi

apt-get install debuild

Flask:

aptitude install python-flask

Test it by the procedure detailed in http://flask.pocoo.org/

ClusterShell:

aptitude install clustershell

Check the project page for more info http://cea-hpc.github.io/clustershell/

PySlurm:

The slurm-web package require pyslurm to be provided by a package called python-pyslurm. In the debian release where this procedure was tested that package didn't exist, so it had to be provided by a dummy package.

First, install the real pyslurm using pip

pip install pyslurm

Test it using the examples shown in http://www.gingergeeks.co.uk/pyslurm/

Then create a dummy package using equivs. First, install equivs if your system doesn't have it:

aptitude install equivs

then create a configuration file for our new package

equivs-control python-pyslurm

.  Now, we should edit the configuration file for the package to provide python-pyslurm [1].  The package will provide nothing in reality, but the package management system will be fooled into thinking that the package is present. The actual functionality is going to be provided by the pyslurm pip package. The important options are presented below:

File: nano python-pyslurm

Section: misc
Priority: optional
Standards-Version: 3.5.10

Package: python-pyslurm
Provides: python-pyslurm
Architecture: all

Description: Dummy package whichs only purpose is to provide pyslurm

Now, build the package:

equivs-build python-pyslurm

And, install it:

dpkg -i python-pyslurm_1.0_all.deb

Bootstrap, jQuery y Float

aptitude install libjs-bootstrap libjs-jquery-flot libjs-jquery-tablesorter

Now, bootstrap must be activated using:

apache - a2enconf javascript-common

 

Installation of the main package

First, it is required to get the latest snapshot of slurm-web from github:

git clone https://github.com/edf-hpc/slurm-web.git

. Then, build the package from the project directory:

debuild -us -uc

Finally, install using dpkg, first the REST api package then the dashboard:

dpkg -i slurm-web-restapi_1.1.3_amd64.deb

dpkg -i slurm-web-dashboard_1.1.3_amd64.deb

 

Configuration and customisation

In /usr/share/slurm-web/ there is a folder called static.  Put a custon logo there.  In /etc/slurm-web/ there is a file called racks.xml.  That file must be edited. The example for GUANE is presented below, but a more general version is shown in the oficial documentation of slurm-web [2]

File: nano python-pyslurm

To do:

Figure out a distribution independent way of installation.  Since it only uses javascript and python, it should be possible to install via "sources" and paths.
