Cross Cluster Search简介 cross-cluster search功能允许任何节点作为跨多个群集的federated client(联合客户端),与tribe node不同的是cross-cluster search节点并不会加入remote cluster(远程集群),而是用轻量的方法连接到remote cluster,以便执行federated search(联合搜索) Remote cluster 要使用cross-cluster search之前需要先了解remote…

The REST API Now that we have our node (and cluster) up and running, the next step is to understand how to communicate with it. Fortunately, Elasticsearch provides a very comprehensive and powerful REST API that you can use to interact with your clus…
The REST API Now that we have our node (and cluster) up and running, the next step is to understand how to communicate with it. 1.Check your cluster, node, and index health, status, and statistics 2.Administer your cluster, node, and index data and m…

配置文件位于%ES_HOME%/config/elasticsearch.yml文件中. cluster.name: elasticsearch 配置集群名称,默认elasticsearch node.name: node1 配置节点名称 node.master: true 配置当前节点是否具有可选为master节点的资格,默认值为true node.data: true 配置当前节点是否允许存储数据,默认值为true node.rack: rack314 每个节点都可以定义一些与之关联的通用属…
关于Elasticsearch的几个概念: 1)在Elasticsearch中,文档归属于类型type,而类型归属于索引index,为了方便理解,可以把它们与传统关系型数据库做类比: Relational DB -> DataBases -> Tables -> Rows -> Columns Elasticsearch -> Indices -> Types -> Documents -> Fields Elasticsearch集群中,可以包含多个索引I…
在正式学习 ElasticSearch 之前,首先看一下 ElasticSearch 中的基本概念. 这些概念将在以后的章节中出现多次,所以花15分钟理解一下是非常值得的. 英文好的同学,请直接移步官网:(http://www.elasticsearch.org/guide/en/elasticsearch/reference/current/_basic_concepts.html) near realtime(nrt) : ElasticSearch 是一款“接近实时(nrt)”的搜索平台,…
这两天需要将ELK中的单节点运行的ES扩展为双节点,查询了下集群配置,百度搜索结果还是一如既往的坑,基本都是各种转帖,以下记录配置静态集群的步骤: * * * <pre><code>sudo vim /etc/elasticsearch/elasticsearch.yml</code></pre> 1. cluster.name: 集群内所有node保持一致 2. node.name: 集群内所有node保持唯一性 3. network.host: 改为no…
elasticsearch的功能,主要用在搜索领域,这里,我来研究这个,也是项目需要,为公司开发了一款CMS系统,网站上的搜索栏功能,我打算采用elasticsearch来实现. elasticsearch的高性能,低延时是最大的吸引力. 系统环境: Centos6.8, X86_64. Elasticsearch的版本: 2.3.5,下载地址来自官网,选择的是RPM包. es安装完毕后,默认安装的路径是/usr/share/elasticsearch, 配置文件,默认是在/etc/elasti…
