Setup with multiple ElasticSearch in one VM

Gopi_Sumanth · March 16, 2020, 1:12pm

I am using elastic-7.6.1. I am trying to setup elastic cluster locally in vm with two masters and one slave.

I have downloaded tar file and extracted into 3 different locations and modified the elasticsearch.yml with the below configurations.

first configuration

cluster.name: test-cluster
node.name: m1node
node.master: true
node.data: true
network.host: xx.xxx.xxx.xx
http.port: 9200
transport.tcp.port: 9300
discovery.seed_hosts:
        - xx.xxx.xxx.xx:9202
        - xx.xxx.xxx.xx:9200
        - 1xx.xxx.xxx.xx:9201
cluster.initial_master_nodes:
        - xx.xxx.xxx.xx:9200
        - xx.xxx.xxx.xx:9201

second configuration

    cluster.name: test-cluster
    node.name: m2node
    node.master: true
    node.data: true
    network.host: xx.xxx.xxx.xx
    http.port: 9201
    transport.tcp.port: 9301
    discovery.seed_hosts:
            - xx.xxx.xxx.xx:9202
            - xx.xxx.xxx.xx:9200
            - xx.xxx.xxx.xx:9201
    cluster.initial_master_nodes:
            - xx.xxx.xxx.xx:9200
            - xx.xxx.xxx.xx:9201

third configuration

cluster.name: test-cluster
node.name: s1node
node.master: false
node.data: true
network.host: xx.xxx.xxx.xx
transport.tcp.port: 9302
http.port: 9202
discovery.seed_hosts:
        - xx.xxx.xxx.xx:9202
        - xx.xxx.xxx.xx:9200
        - xx.xxx.xxx.xx:9201
cluster.initial_master_nodes:
        - xx.xxx.xxx.xx:9200
        - xx.xxx.xxx.xx:9201

I started the three elastic search instances using ./elasticsearch. The server starts but it doesn't discover other nodes.I get this error.

Can someone please help me with this issue.I am new to elastic search.Thank you

Hey,

first there is no such thing as a slave node. The node.master setting is only about being master eligible.

Second, you are trying to connect to the HTTP ports of your nodes, instead of using the node-to-node port, which is 9300. This is also why you are getting an error like received HTTP response on transport port, ensure that transport port (not HTTP port) of a remote node is specified in the configuration which tries to hint at the fact, that there seems to be a mixup between HTTP and node-to-node communication.
