【ElasticSearch 6.】 学习三：分布式安装

• 主master的配置

cluster.name: lihe
node.name: master
node.master: true
network.host: 127.0.0.1

• 分slave的配置

xpack.ml.enabled: fales
http.cors.enabled: true
http.cors.allow-origin: \"*\"
cluster.name: lihe
node.name: slave1
node.master: false
network.host: 127.0.0.1
http.port: 8200
discovery.zen.ping.unicast.hosts: [\"127.0.0.1\"]

tip:

• cluster.name 必须保持一致

• salve的discovery.zen.ping.unicast.hosts不能缺少不然找不到master

• 启动服务报错：[2018-12-19T11:19:49,420][WARN ][o.e.b.ElasticsearchUncaughtExceptionHandler] [master] uncaught exception in thread [main] org.elasticsearch.bootstrap.StartupException: java.lang.IllegalStateException: failed to obtain node locks, tried [[D:\\Mooc\\elasticsearch-6.5.3\\data\\lihe]] with lock id [0]; maybe these locations are not writable or multiple nodes were started without increasing [node.max_local_storage_nodes] (was [1])?

  解决方法：rm -rf data/nodes

• 启动服务 访问head
