Docker安装Elasticsearch 7.6.1 + /Easticsearch-Head 5

一、Docker 安装 ElasticSearch

1、从仓库中查找所有ElasticSearch的镜像

[root@localhost ~]# docker search elasticsearch

2、选择一个版本镜像进行拉取

[root@localhost ~]# docker pull elasticsearch:7.6.1

3、查看镜像

[root@localhost ~]# docker images

4、通过镜像，启动一个容器，并将9200和9300端口映射到本机

[root@localhost ~]# docker network create somenetwork

[root@localhost ~]# docker run -d --name es --net somenetwork -p 9200:9200 -p 9300:9300 -e "discovery.type=single-node" elasticsearch:7.6.1

5、 配置跨域，进入容器内部，修改elasticsearch.yml

[root@localhost ~]# docker exec -it es /bin/bash

[root@localhost elasticsearch]# ls
LICENSE.txt  NOTICE.txt  README.textile  bin  config  data  lib  logs  modules  plugins
[root@localhost elasticsearch]# cd config/
[root@localhost config]# ls
elasticsearch.keystore  ingest-geoip  log4j2.properties  roles.yml  users_roles
elasticsearch.yml       jvm.options   role_mapping.yml   users
[root@localhost config]# vi elasticsearch.yml

新增跨域配置

cluster.name: "docker-cluster"
network.host: 0.0.0.0
http.cors.enabled: true
http.cors.allow-origin: "*"
  
# minimum_master_nodes need to be explicitly set when bound on a public IP
# set to 1 to allow single node clusters
# Details: https://github.com/elastic/elasticsearch/pull/17288
discovery.zen.minimum_master_nodes: 1

6、重启ElasticSearch容器

[root@localhost ~]# docker restart es

7、 浏览器访问ip:9200

{
	name: "1f5a9f949292",
	cluster_name: "docker-cluster",
	cluster_uuid: "TlppYOEORbK1PvcFDTTZbQ",
	version: {
	number: "7.6.1",
	build_flavor: "default",
	build_type: "docker",
	build_hash: "aa751e09be0a5072e8570670309b1f12348f023b",
	build_date: "2020-02-29T00:15:25.529771Z",
	build_snapshot: false,
	lucene_version: "8.4.0",
	minimum_wire_compatibility_version: "6.8.0",
	minimum_index_compatibility_version: "6.0.0-beta1"
	},
	tagline: "You Know, for Search"
}

二、Docker 部署 ElasticSearch-Head

ElasticSearch-Head是一个管理界面，可以查看ElasticSearch相关信息
1、拉取ElasticSearch-Head镜像

[root@localhost ~]# docker pull mobz/elasticsearch-head:5
5: Pulling from mobz/elasticsearch-head
75a822cd7888: Pull complete 
57de64c72267: Pull complete 
4306be1e8943: Pull complete 
871436ab7225: Pull complete 
0110c26a367a: Pull complete 
1f04fe713f1b: Pull complete 
723bac39028e: Pull complete 
7d8cb47f1c60: Pull complete 
7328dcf65c42: Pull complete 
b451f2ccfb9a: Pull complete 
304d5c28a4cf: Pull complete 
4cf804850db1: Pull complete

2、 运行ElasticSearch-Head容器

[root@localhost ~]# docker run -d --name es_admin -p 9100:9100 mobz/elasticsearch-head:5
a8affb38d3ad7f66b2bb5f7a9a28363bfc48309143b7e9892fe2f9c40ba1f4b4

3、浏览器访问 ip:9100

三、Docker部署ik中文分词插件

1、进入es容器内部，/plugins下新建ik文件夹

[root@localhost ~]# docker exec -it es /bin/bash
[root@1f5a9f949292 elasticsearch]# ls
LICENSE.txt  NOTICE.txt  README.asciidoc  bin  config  data  jdk  lib  logs  modules  plugins
[root@1f5a9f949292 elasticsearch]# cd plugins/
[root@1f5a9f949292 plugins]# mkdir ik
[root@1f5a9f949292 plugins]# ls
ik

2、下载与es对应版本的ik压缩包，并解压

下载地址：https://github.com/medcl/elasticsearch-analysis-ik/releases

[root@1f5a9f949292 ik]# wget https://github.com/medcl/elasticsearch-analysis-ik/releases/download/v7.6.0/elasticsearch-analysis-ik-7.6.0.zip

[root@1f5a9f949292 ik]# unzip elasticsearch-analysis-ik-7.6.0.zip

[root@1f5a9f949292 ik]# ls
commons-codec-1.9.jar    config                               elasticsearch-analysis-ik-7.6.0.zip  httpcore-4.4.4.jar            plugin-security.policy
commons-logging-1.2.jar  elasticsearch-analysis-ik-7.6.0.jar  httpclient-4.5.2.jar                 plugin-descriptor.properties

3、退出容器，重启es容器

[root@1f5a9f949292 ik]# exit
[root@localhost ~]# docker restart es
es

4、测试ik分词插件，postman请求以下参数

ip:9200/_analyze?pretty=true

{
	"analyzer": "ik_max_word",
	"text": "随便打一句话"
}

注意analyzer这个单词上下是不一样的

至此Docker安装 Elasticsearch已基本完成
