Setting up networking

Correctly setting up networking is very important for your nodes and cluster.

There are a lot of different installation scenarios and networking issues: the first step for configuring the nodes to build a cluster is to correctly set the node discovery.

Getting ready

You need a working Elasticsearch installation and know your current networking configuration (that is, IP).

How to do it...

For configuring networking, we will perform the following steps:

• Open the Elasticsearch configuration file with your favorite text editor.

• Using standard Elasticsearch configuration config/elasticsearch.yml file, your node is configured to bind on all your machine interfaces and does discovery broadcasting events to the nodes listed in discovery.zen.ping.unicast.hosts. This means that it sends signals to the machine in unicast list and waits for a response. If a node responds to it, they can join in a cluster.

• If another node is available in the same LAN, they join the cluster.
