perfSONAR User Q&A and Other Discussion

[Andrew Lake <>]

Hi,

No command but below is a snippet derived from a script (https://github.com/perfsonar/toolkit/blob/master/scripts/system_environment/configure_esmond) that comes on the toolkit which parses the output of the command and drop the result in meshconfig-agent-tasks.conf . Drop that in a bash script, have chef execute it and you should be good to go. We do something similar with cfengine on ESnet.

--------

export ESMOND_ROOT=/usr/lib/esmond

#initialize python

cd $ESMOND_ROOT

if [ -e /opt/rh/python27/enable ]; then

    source /opt/rh/python27/enable

    /opt/rh/python27/root/usr/bin/virtualenv --prompt="(esmond)" .

fi

. bin/activate

#create api key

KEY=`python esmond/manage.py add_api_key_user perfsonar 2> /dev/null | grep "Key:" | cut -f2 -d " "`

#set API Key in meshconfig-agent-tasks.conf

if [ -n "$KEY" ]; then

    grep -q ESMOND_API_KEY /etc/perfsonar/meshconfig-agent-tasks.conf

    if [ $? == 0 ]; then

        sed -i "s/ESMOND_API_KEY/$KEY/g" /etc/perfsonar/meshconfig-agent-tasks.conf

    fi

fi

A quick question about these database user accounts. Is there a way that I can specify the username and api key secret via CLI? Otherwise I've got to figure out how to make chef capture the results of this command and frankly that sounds like a big PITA. Help me Obi-Wan Kenobe!

Whoops, hit send too quick on the previous note.

For this one, no need to install anything via pip, simply run the following:

cd /usr/lib/esmond

. bin/activate

python esmond/manage.py add_ps_metadata_post_user perfdata

That will get you in esmond’s python virtualenv, which has everything installed that you need. We already have an issue to update the docs everywhere to say that, just hasn’t made its way in yet, sorry for the confusion.

This section is in dire need of some love it seems and I am completely stuck here as you will see.

[root@management-centos-71 esmond]# python esmond/manage.py add_ps_metadata_post_user perfdata

Traceback (most recent call last):

  File "esmond/manage.py", line 2, in <module>

    from django.core.management import execute_from_command_line

ImportError: No module named django.core.management

[root@management-centos-71 esmond]# pip freeze | grep -i django
