ElasticSearch安装

ElasticSearch 下载

ES的官方下载地址：https://www.elastic.co/downloads/elasticsearch，大家可以按照自己的操作系统选择合适版本，目前的最新版本是6.4。

ElasticSearch 运行

我的开发环境是MAC，解压压缩包，在终端输入ls命令，会有以下文件目录：

elasticsearch               elasticsearch-service.bat
elasticsearch-certgen           elasticsearch-setup-passwords
elasticsearch-certgen.bat       elasticsearch-setup-passwords.bat
elasticsearch-certutil          elasticsearch-sql-cli
elasticsearch-certutil.bat      elasticsearch-sql-cli-6.4.0.jar
elasticsearch-cli           elasticsearch-sql-cli.bat
elasticsearch-cli.bat           elasticsearch-syskeygen
elasticsearch-croneval          elasticsearch-syskeygen.bat
elasticsearch-croneval.bat      elasticsearch-translog
elasticsearch-env           elasticsearch-translog.bat
elasticsearch-env.bat           elasticsearch-users
elasticsearch-keystore          elasticsearch-users.bat
elasticsearch-keystore.bat      elasticsearch.bat
elasticsearch-migrate           x-pack
elasticsearch-migrate.bat       x-pack-env
elasticsearch-plugin            x-pack-env.bat
elasticsearch-plugin.bat        x-pack-security-env
elasticsearch-saml-metadata     x-pack-security-env.bat
elasticsearch-saml-metadata.bat     x-pack-watcher-env
elasticsearch-service-mgr.exe       x-pack-watcher-env.bat
elasticsearch-service-x64.exe

可以看到各种文件格式，本机在bin目录下运行

./elasticsearch

如果是windows则

./elasticsearch.bat

如果作为守护进程运行，则需要添加参数 -d

./elasticsearch -d

测试是否运行成功

输入测试url

curl 'http://localhost:9200/?pretty'

如果正常的话，会有以下结果：

{
  "name" : "r9uUfUB",
  "cluster_name" : "elasticsearch",
  "cluster_uuid" : "E7L452raSgOC6w1CnClnHg",
  "version" : {
    "number" : "6.4.0",
    "build_flavor" : "default",
    "build_type" : "tar",
    "build_hash" : "595516e",
    "build_date" : "2018-08-17T23:18:47.308994Z",
    "build_snapshot" : false,
    "lucene_version" : "7.4.0",
    "minimum_wire_compatibility_version" : "5.6.0",
    "minimum_index_compatibility_version" : "5.0.0"
  },
  "tagline" : "You Know, for Search"
}

使用kibana sense

虽然sense不是必备的，但是增强了与es的交互体验，先下载kibana：https://www.elastic.co/downloads/kibana
解压安装过程跟es是一样的，目前的版本6.4集成了sense，直接在运行，启动成功后在浏览器键入地址：localhost:5601，会出现以下页面：

总结

以上是ElasticSearch的安装，谢谢。
