Elasticsearch集群搭建
现有两部机器：192.168.31.86，192.168.31.87
参考以往博文对Elasticsearch进行配置完成：http://www.cnblogs.com/zhongshengzhen/p/elasticsearch_mysql.html 1、注意事项 集群需要在同一网段 2、配置elasticsearch.yml cluster.name ：配置es的集群名称，不同的集群用名字来区分， 如果在同一网段下有多个集群，就可以用这个属性来区分不同的集群。 node.name：节点名称，一部服务器一个节点，分别为node-1，node-2，node-3 。 http.port ：服务端口，一般默认是9200，如果在同一部服务器上面配置多个elasticsearch服务，则端口需要不同 discovery.zen.ping.unicast.hosts：自动检索可用节点，设置了这个参数才会自动检测可用的节点。 同一集群名下，elasticsearch会自动去发现其他的节点。 具体配置： 192.168.31.86： cluster.name: mycluster node.name: node-1 #指定了该节点可能成为 master 节点，还可以是数据节点node.master: true
node.data: true network.host: 192.168.31.86 http.port: 9200 transport.tcp.port: 9300 discovery.zen.ping.unicast.hosts: ["192.168.31.86", "192.168.31.87"] 192.168.31.87： cluster.name: mycluster node.name: node-2 #指定了该节点可能成为 master 节点，还可以是数据节点
node.master: true
node.data: true network.host: 192.168.31.87 http.port: 9200 transport.tcp.port: 9300 discovery.zen.ping.unicast.hosts: ["192.168.31.86", "192.168.31.87"] 然后分别启动两个节点的ES服务。 安装Head
Head是一个用来监控Elasticsearch状态的客户端插件。 检查两个节点的情况： 192.168.31.86： [zsz@zsz elasticsearch-2.3.2]$ curl '192.168.31.86:9200/_cat/indices?v'
health status index pri rep docs.count docs.deleted store.size pri.store.size
green open myindex 5 1 163 0 294kb 147kb
green open customer 5 1 0 0 1.5kb 795b 192.168.31.87： [zsz@VS-SUPSV-TEST1 elasticsearch-2.3.2]$ curl '192.168.31.87:9200/_cat/indices?v'
health status index pri rep docs.count docs.deleted store.size pri.store.size
green open myindex 5 1 163 0 294kb 147kb
green open customer 5 1 0 0 1.5kb 795b 发现是GREEN的绿色健康状态，说明备份被分配完成，可用。集群配置完成。 测试集群中两个节点的查询情况： [zsz@zsz ~]$ curl '192.168.31.87:9200/myindex/_search?q=ghdfdfgddfg'
