我这边安装的是ES5.5版本，官方文档地址：[ES-5.5安装][ES-5.5]

Elastic5.5 需要 Java 8 环境。安装完 Java后，就可以跟着官方文档安装 Elastic。直接下载压缩包比较简单。

1、下载安装包

curl -L -O https://artifacts.elastic.co/downloads/elasticsearch/elasticsearch-5.5.3.tar.gz

2、解压

sudo tar -xvf elasticsearch-5.5.3.tar.gz

3、修改解压后的elasticsearch-5.5.3文件用户所属，注意当前用户和用户组必须是非root用户，

sudo chown -R noroot:noroot elasticsearch-5.5.3
    或者
    sudo chown -R noroot elasticsearch-5.5.3

4、安装目录下启动

elasticsearch-5.5.3/bin/elasticsearch

5、检验

$ curl localhost:9200
    {
      "name" : "2WFBZrz",
      "cluster_name" : "elasticsearch",
      "cluster_uuid" : "_jK-nqFKSCeLfinT0u4ubg",
      "version" : {
        "number" : "5.5.3",
        "build_hash" : "9305a5e",
        "build_date" : "2017-09-07T15:56:59.599Z",
        "build_snapshot" : false,
        "lucene_version" : "6.6.0"
      },
      "tagline" : "You Know, for Search"
    }

至此，elasticsearch的安装初步完成，如果中间报错，可以参考该博文[elasticsearch 安装过程中可遇到的问题][elasticsearch]

**附：ES相关文档**  
[官方文档][Link 1]

除了官方文档，可以看下这篇中文译文：  
[Elasticsearch 权威指南（中文版）][Elasticsearch]

**附：中文分词插件IK安装**  
参考：[elasticsearch-analysis-ik][]

**附：安装elasticsearch-head插件**  
参考：[Mac上安装elasticsearch-head插件][Mac_elasticsearch-head]

如果出现ES-HEAD插件连接不上ES集群，

elasticsearch-5x下的 config/elasticsearch.yml 增加如下配置：

http.cors.enabled: true
    http.cors.allow-origin: "*"
