monetdb cluster management can't setup

I'm trying to follow MonetDB docs on Cluster Management

to setup a 3 nodes cluster using 3 Centos machines, I created the 3 dbfarm using monetdbd create /path/to/mydbfarm and from the first node, I run monetdb discover and it returns nothing where it should discover the other nodes, and when I try to run monetdb -h [second node IP] -P mypasshphrase status it returns the following error

status: cannot connect: Connection refused

PS: I have a passwordless connection between these 3 nodes, ssh [any node IP] works just fine,

Thank you

Solution

  • By default MonetDB listens only for local connections. This is for security reasons.

    To listen also for remote connections, run

    monetdbd set listenaddr=0.0.0.0 .../path/to/dbfarm

    on each of the nodes and restart monetdbd.
