Does anyone have 2 or more instances running Elastic Search on the same machine?


(age) #1

Good morning

Does anyone have 2 or more instances running Elastic Search on the same
machine? Problems who live 2 instances of Elastic Search in the same
machine? Besides that would have to share the RAM, and consultation would
be slower.

A greeting and thanks

Lots of people do, by either running two processes manually managed, or
using container technology like Docker.
Obviously you'd increase your management overhead, but I haven't heard any
major issues from others using these methods.

I have 2 instances in one server, but none of them are data node, one is
master (-Des.node.master=true -Des.node.data=false) and another is use for
search balance (-Des.node.master=false -Des.node.data=false), totally fine,
no load at all.

But if these are data nodes, you probable shouldn't do that, better be one
instance per machine.

I understand that you do not have two elasticsearch both operating, which
have no problems with RAM or problems slow queries.
In my case I need to install two elasticsearch in the same machine, and not
know it would cause me problems in the short and long term.
For example had thought about playing with the parameters of the RAM and
Cache, but not if I could play some more parameter, so that the coexistence
of both elastic was the best.

Thank you.
