ES 集群

详情: http://www.javashuo.com/article/p-rpbsowhq-cm.html 将实验机器/etc/elasticsearch/elasticsearch.yml 中配置文件改成

cluster.name: myes           　 #ES集群名称
node.name: node-2         ##节点名称
path.data: /data/es-date       #数据存储的目录（多个目录使用逗号分隔）
path.logs: /var/log/elasticsearch #日志格式
bootstrap.memory_lock: true   #锁住es内存，保证内存不分配至交换分区
network.host: 192.168.83.30   #设置本机IP地址
http.port: 9200            #端口默认9200
discovery.zen.ping.unicast.hosts: ["192.168.83.20", "192.168.83.30"]

提示:cluster.name 同样便可被发现
