创建集群目录

mkdir -p /usr/local/elasticsearch-7.5.0-node-1/config &&

mkdir -p /usr/local/elasticsearch-7.5.0-node-1/data &&

mkdir -p /usr/local/elasticsearch-7.5.0-node-1/plugins/ik &&

mkdir -p /usr/local/elasticsearch-7.5.0-node-2config &&

mkdir -p /usr/local/elasticsearch-7.5.0-node-2/data &&

mkdir -p /usr/local/elasticsearch-7.5.0-node-2/plugins/ik &&

mkdir -p /usr/local/elasticsearch-7.5.0-node-3/config &&

mkdir -p /usr/local/elasticsearch-7.5.0-node-3/data &&

mkdir -p /usr/local/elasticsearch-7.5.0-node-3/plugins/ik

修改目录权限

chmod 777 -R /usr/local/elasticsearch-7.5.0-node-1 &&
chmod 777 -R /usr/local/elasticsearch-7.5.0-node-2 &&
chmod 777 -R /usr/local/elasticsearch-7.5.0-node-3

分别在node1,node2,node3的config目录下创建elasticsearch.yml文件

node1的elasticsearch.yml

cluster.name: es-cluster
node.name: es-node-1
node.master: true
node.data: true
 
network.host: es-node-1
http.port: 9200

bootstrap.memory_lock: true
action.destructive_requires_name: true

node3的elasticsearch.yml

cluster.name: es-cluster
node.name: es-node-3
