elasticsearch集群部署

启动elk:

zjtest7-redis:/usr/local/elasticsearch-2.3.4/bin# ./elasticsearch -d 后台运行

访问；

Elasticsearch 目录结构:

文件夹                   作用

/bin                     运行ElasticSearch实例和管理插件的一些脚本

/config 配置文件路径,包含elasticsearch.yml

/data    在节点上每个索引/碎片 的数据文件的位置,可以多个目录

[elk@zjtest7-redis config]$ cat elasticsearch.yml 

cluster.name: es_cluster
node.name: node01
path.data: /elk/elasticsearch/data
path.logs: /elk/elasticsearch/logs
network.host: 192.168.32.80
network.port: 9200

3.2 Elasticsearch 相关插件；

1. Head 插件介绍

2. Bigdesk插件介绍

head 插件是一个elasticsearch的集群管理工具,它是完全由html5编写的独立网页程序

安装插件:

elk@zjtest7-redis elasticsearch-2.3.4]$ ./bin/plugin install mobz/elasticsearch-head 

-> Installing mobz/elasticsearch-head...  

http://192.168.32.80:9200/_plugin/head/

Bigdesk 插件是elasticsearch 的一个集群监控工具,可以通过它来查看集群的各种状态,如:

cpu，内存,使用情况,索引数据,搜索情况,http连接数等。

[elk@zjtest7-redis bin]$ ./plugin  install lukas-vlcek/bigdesk/2.5.0

在部署一台 192.168.32.81:

启动[elk@zjtest7-redis2 bin]$ ./elasticsearch -d
[elk@zjtest7-redis2 bin]$ 

http://192.168.32.81:9200/

{
  "name" : "node02",
  "cluster_name" : "es_cluster",
  "version" : {
    "number" : "2.3.4",
    "build_hash" : "e455fd0c13dceca8dbbdbb1665d068ae55dabe3f",
    "build_timestamp" : "2016-06-30T11:24:31Z",
    "build_snapshot" : false,
    "lucene_version" : "5.5.0"
  },
  "tagline" : "You Know, for Search"
}

配置文件:

cluster.name: es_cluster
node.name: node02
path.data: /elk/elasticsearch/data
path.logs: /elk/elasticsearch/logs
network.host: 192.168.32.81
network.port: 9200
discovery.zen.ping.unicast.hosts: ["192.168.32.80", "192.168.32.81"]

discovery.zen.ping.unicast.hosts: ["192.168.80.10", "192.168.80.20"]
位于配置文件的第79行，用于定义elasticsearch发送广播的ip，默认情况下向elasticsearch所在网段的所以ip进行广播

默认会同步数据

[elk@zjtest7-redis2 plugins]$ ls
[elk@zjtest7-redis2 plugins]$
