Elasticsearch add datanode to existing cluster
I have cluster with
- elasticnode1 – master-node
- elasticnode2 – datanode
- elasticnode3 – datanode
- elasticnode4 – datanode
I want add new node
- elasticnode4 – datanode
Setup same version on elasticnode5 – i setup elasticsearch.5.6.3
wget https://artifacts.elastic.co/downloads/elasticsearch/elasticsearch-5.6.3.deb
Add node to config on all nodes
nano /etc/elasticsearch/elasticsearch.yml
discovery.zen.ping.unicast.hosts: ["elasticnode1", "elasticnode2", "elasticnode3", "elasticnode4", "elasticnode5"]
Start cluster rebalancing by put query
curl -XPUT http://elasticnode1:9200/_cluster/settings -d '{
"transient" : {
"cluster.routing.allocation.enable" : "all"
}
}'
