### 一、es官网 ###

es官网：

[免费且开放的搜索：Elasticsearch、ELK 和 Kibana 的开发者 | Elastic我们是 Elastic (ELK) Stack——Elasticsearch、Kibana、Beats 和 Logstash——的开发者。安全又可靠地搜索、分析和可视化您的数据，无论在云中，还是使用本地部署。![apple-icon-57x57.png][]https://www.elastic.co/cn/][Elasticsearch_ELK _ Kibana _ _ Elastic_ Elastic _ELK_ Stack_Elasticsearch_Kibana_Beats _ Logstash_apple-icon-57x57.png_https_www.elastic.co_cn]

### 二、ELKB介绍 ###

*  Elasticsearch：基于Json的分布式搜索和分析引擎

![4b7b3276dc004fca8220f13c4e46e317.png][]

*  Logstash：动态数据收集管道，生态丰富

![c941c3bb512d471e9e2e2894e31f45a3.png][]

*  Kibana: 提供数据的可视化界面

![d99f02772a2d414fa99866783afcb6b2.png][]

*  Beats：轻量级的数据采集器（用于替代logstash）

beats属于轻量级，并且beats是用go语言开发的，logstash也是用java语言开发的，导致数据量很大时，logstash会进行资源抢占。所以后面用beats代替logstash![96736034b3fc4e659cb19fc2be500547.png][]

### 三、安装es ###

#### 1. 安装jdk ####

因为elasticsearch使用java开发的，所以需要java环境

建议安装jdk8、jdk11、jdk14（版本兼容性问题）

#### 2. 安装elasticsearch ####

![816af3931eaf45c6b0b6a6d700596527.png][]

下载完成，解压就可以使用了

![83e574a0ae6d4267b56cdff8be447b10.png][]

#### 3. 启动es ####

\-d：以守护线程的方式启动，也可以不加

![e071b5edafcb4f059f36325fa5013aeb.png][]

通过[http://localhost:9200/][http_localhost_9200] 来验证

![aac6956aa161418a83de0158b6ae199f.png][]

*  name: 如果没有配置，默认是主机名（在elasticsearch.yml文件中修改）
 *  cluster\_name: 如果没有配置，默认是"elasticsearch",
 *  cluster\_uuid: 集群唯一id

### 四、安装kibana ###

#### 1.下载 ####

![921f08603dde44668026407d86ec3b58.png][]

[Download Kibana Free | Get Started Now | Elastic][Download Kibana Free _ Get Started Now _ Elastic]

#### 2. 启动 ####

![b4b2dfcf8ef84f6aaf59f40ad861e10d.png][]

kibana在启动时，需要连接es的服务。所以需要在启动kibana之前启动es的服务

检验：[http://localhost:5601/app/kibana][http_localhost_5601_app_kibana]

![73aa266150db408088050fa2b2d53afb.png][]

如果es的ip、端口号发生改变，需要需要kibana.yml文件

#### 3. 关闭kibana ####

![f76589d9a0d048ed8b3d9121f7c8770d.png][]

![c0d958349b884f40a81892da42971d2f.png][]

### 五、安装head插件 ###

#### 1. 安装node插件 ####

[Download | Node.js][Download _ Node.js]

node -v 命令校验node安装成功

![6ecec43062a74e43bde05c256197ad07.png][]

#### 2. 安装grunt ####

执行 npm install -g grunt -cli 命令安装

grunt -version命令检查安装成功

![9937c791568c4361a3b7d2f55e205e39.png][]

#### 3. 安装head插件 ####

[GitHub - mobz/elasticsearch-head: A web front end for an elastic search cluster][GitHub - mobz_elasticsearch-head_ A web front end for an elastic search cluster]

按照这些命令执行

![d671551d67ec49e5b04637cfe079ef6c.png][]

要是不行，按照以下步骤

![99f247d6f2dd43b9ab08c16e68358a4a.png][]

在安装目录运行npm run start

![71e678dda5e74806849b0ecda842ad17.png][]

[Node Exporter][]![344428ac3301455588b75e0f84ad9a6b.png][]

可以方便的看到集群中的节点

五角星代表主节点

![ce7a57f26691461b8129e30d75acfe93.png][]

### 六、集群健康值检查 ###

#### 1. 健康值状态 ####

![b3f0d04fab9e4eb4a3adb8a8ca0ffcf2.png][]

其中，Primary是主分片，Replica是副本分片

以下操作将会产生6个副本分片和3个主分片

![f135d0b8370e4511bb74dd33849e4570.png][]

#### 2. 查看健康值状态 ####

GET \_cat/health?v
