I made complete installs on two nodes turned everything on, and so far so good.
But my question is this:
So far I have a 2 server SciDB installation, the coordinator is 10.0.0.15 and one other node (server-1, say) is on 10.0.0.13
I did a full install on both. I run scidb.py initall on the coordinator, and then followed by startall and all seems well.
Now I have a ten new nodes I can use, 10.0.0.1, – 10.0.0.10.
What is the minimum install I need to do on the new ten worker bees?
The coordinator exports /opt/scidb, so all ten worker bees see 12.3/bin/ and everything else.
All ten have a scidb user, a home, a passwordless sudo–though the latter may not be needed, since postgres is setup happens only on the coordinator, yes?
Is that enough, or do I need anything else installed (postgres clientware? – in theory they could be embedded in one of the executables in the exported scidb/bin, but are they? does the worker bee need the python expansions for ssh remote calls back to the coordinator?)
I am trying to automate adding new nodes into the mix and install only what is necessary and nothing else.
If this is already in the manuals, I apologize, and please direct me to the proper section and I promise to RTFM it
Many thanks in advance,
