Hazelcast dedicated nodes

What is the simplest way to run Hazelcast nodes on dedicated servers?

We have a web application that uses a Hazelcast distributed map. Currently the Hazelcast nodes are configured to run in the Servlet Container nodes.

As we scale up, we'd like to add dedicated hardware as Hazelcast nodes.

Then we won't need full Hazelcast nodes in the Servlet Containers anymore, those can be clients. (There are licensing costs associated with the Servlet Containers, so开发者_如何学C getting load off them is good, don't ask...)

So the question is, what's a minimal Hazelcast node installation? Something analogous to a memcached installation. All it needs to do is read configuration and start up, no local clients.

I see it supports Jetty, but is that needed at all, or is there some simple class in those jars I could execute on a JVM raw?

Just create a simple class that calls HazelCast.init

There are a number of test classes in the com.hazelcast.examples package which can be run from the bin directory of the hazelcast distribution.

TL;DR

Newer version:

java -cp hazelcast-3.7.2.jar com.hazelcast.core.server.StartServer

Older version:

java -cp hazelcast-2.0.3.jar com.hazelcast.examples.StartServer

This will start a standalone Hazelcast instance

If you're using maven:

mvn -DgroupId=com.hazelcast -DartifactId=hazelcast -Dversion=3.7.2 dependency:get

cd ~/.m2/repository/com/hazelcast/hazelcast/3.7.2

will get you to the folder with the jar

You can get it to run by calling {hazelcast-directory}/bin/server.shor on Windows {hazelcast-directory}/bin/server.bat.

The configuration file can still be found in {hazelcast-directory}/bin/hazelcast.xml

This is an update to thSoft's answer as that way is no longer valid.

You can also simply run hazelcast/bin/start.sh (the configuration file is hazelcast/bin/hazelcast.xml).
