在hazelcast中自动聚类

Question

I tested with the hazelcast-default.xml,

What is happening is I have started a node 192.X.1.1 with port as 5701 and it becomes up and works like a fly,

Mean while, I started a node 192.X.1.2 with port 5701 and I wonder It does a mapping and join together, How to avoid that,

Is the param cluster.min setting to '1', solves the problem???

Answer 1

I am assuming that by cluster min setting you mean hazelcast.initial.min.cluster.size . That is unrelated to this issue. This property simply requires an x number of nodes to join the cluster before starting your application.

What you are looking for depends on whether you are using multicast or TCP-IP to discover nodes. See this book for details: http://hazelcast.com/resources/mastering-hazelcast/

In case of multicasting you need to set groups, and add the nodes to different groups.

You could also simply define interfaces such as: 192.168.24.*

with the range of IP you want to by accepted by your cluster.

Finally if you are using TCP-IP you need to define the ip of the nodes that will join your cluster. A simple example being :

            <hz:join>
                <hz:multicast enabled="false" />
                <hz:tcp-ip enabled="true">
                    <hz:members>192.168.0.1</hz:members>
                </hz:tcp-ip>
            </hz:join>

(Example shown are using spring configuration)
