- 日理万妓 2022-07-26 05:20 237阅读 0赞

**1.术语讲解**  
cluster：集群  
Node:节点  
Index:类似mysql的database  
Type:类似mysql的table  
Doccument:内容  
Shard:数据分片，shard的最大默认Doccument数是2,147,483,519  
Replicas:数据副本数，查询时也会用到，不仅仅是备份

**2.安装**

(a)elasticsearch运行依赖jre，jre的安装可参考：[ubuntu安装jre][ubuntu_jre]

(b)下载地址：[https://www.elastic.co/][https_www.elastic.co]，点击右上角downloads

(c)我选择的版本是elasticsearch-2.2.0.tar.gz

(d)解压：tar -zxvf elasticsearch-2.2.0.tar.gz

(e)解压即可用，执行程序在bin目录下面

(f)后台运行：./elasticsearch -d

**3.检查集群健康状态**

curl 'localhost:9200/\_cat/health?v'

status有三种：Green，yellow，red

![20160407232810474][]

**4.检查集群的节点**

curl 'localhost:9200/\_cat/nodes?v'

\*号标注的节点是master节点

![20160407232823599][]

**5.显示所有的index**

curl 'localhost:9200/\_cat/indices?v'

![20160407232832724][]

pri:也就是shard，默认5  
rep:也就是Replicas，默认1

**6.创建删除index**  
index:customer  
pretty:显示优化,换行  
创建：curl -XPUT 'localhost:9200/customer?pretty'  
删除：curl -XDELETE 'localhost:9200/customer?pretty'

**7.关于配置**  
ES\_HOME/config目录下：  
主配置：elasticsearch.yml  
日志配置：logging.yml

单点elasticsearch的配置参考：

cluster.name: bs2test
    network.host: 0.0.0.0
    path.logs: /data/elasticsearch/logs
    path.data: /data/elasticsearch/data

**小结：细节很多，主要看官网的配置文档**
