vim /etc/elasticsearch/elasticsearch.yml

cluster.name: my-els                               # 集群名称
node.name: els-node1                               # 节点名称，仅仅是描述名称，用于在日志中区分

path.data: /opt/elasticsearch/data                 # 数据的默认存放路径
path.logs: /opt/elasticsearch/log                  # 日志的默认存放路径

network.host: 192.168.60.201                        # 当前节点的IP地址
http.port: 9200                                    # 对外提供服务的端口，9300为集群服务的端口
#添加如下内容
#culster transport port
transport.tcp.port: 9300
transport.tcp.compress: true

discovery.zen.ping.unicast.hosts: ["192.168.60.201", "192.168.60.202","192.168.60.203"]       
# 集群个节点IP地址，也可以使用els、els.shuaiguoxia.com等名称，需要各节点能够解析

discovery.zen.minimum_master_nodes: 2              # 为了避免脑裂，集群节点数最少为 半数+1

mkdir /data/elasticsearch
chown -R elasticsearch.elasticsearch /data/elasticsearch

systemctl enable elasticsearch
