perfSONAR User Q&A and Other Discussion

["Mike Cruzz" <>]

Right of course I had nothing to lose by trying out the 3rd experiment.

So I spun up VM3 and also installed "yum install perfsonar-centralmanagement"

I went back to VM1 and then checked I could connect to postgres remotely after
making some changes on VM3 to allow remote connectivity to the esmond postgres
database.

I then re-ran
esmond_manage add_user_ip_address test-user 10.10.10.0/24

Creating entry for IP 10.10.10.0/24 belonging to test-user


I guess the next step in the experiment to get VM2 working is to export the
database from VM3 and import it into VM2.

Then restore a VM snapshot on VM1 and retest the esmond_manage
add_user_ip_address test-user 10.10.10.0/24 to see if maybe it does not like
an empty database.

Hopefully I get somewhere to create the postgress database external to the all
in 1 VM.

This may all be unconventional but my limited knowledge in all these
technologies the only option is trial and error.

After this the last step would be to add the http haproxy and keepalived to
loadbalance the httpd traffic but onto problem 2 :))
