Docker安装ElasticSearch 版本7.1.1

一、Docker 部署 ElasticSearch

1、从仓库中查找所有ElasticSearch的镜像

[root@iZwz99dhxbd6xwly17tb3bZ app]# docker search elasticsearch

2、选择一个版本镜像进行拉取

[root@iZwz99dhxbd6xwly17tb3bZ ~]# docker pull docker.elastic.co/elasticsearch/elasticsearch:7.1.1

Trying to pull repository docker.elastic.co/elasticsearch/elasticsearch ...

7.1.1: Pulling from docker.elastic.co/elasticsearch/elasticsearch

Status: Downloaded newer image for docker.elastic.co/elasticsearch/elasticsearch:7.1.1

3、查看镜像

[root@iZwz99dhxbd6xwly17tb3bZ ~]# docker images

REPOSITORY                                      TAG                 IMAGE ID            CREATED             SIZE

docker.io/hello-world                           latest              4ab4c602aa5e        2 weeks ago         1.84 kB

docker.elastic.co/elasticsearch/elasticsearch   7.1.1               96dd1575de0f        2 months ago

4、通过镜像，启动一个容器，并将9200和9300端口映射到本机（ElasticSearch的默认端口是9200，我们把宿主环境9200端口映射到Docker容器中的9200端口）

[root@iZwz99dhxbd6xwly17tb3bZ ~]# docker run -d --name es -p 9200:9200 -p 9300:9300 -e ES_JAVA_OPTS="-Xms512m -Xmx512m" -e "discovery.type=single-node" docker.elastic.co/elasticsearch/elasticsearch:7.1.1

c11ef1beb4f3e82d74b8709f9462e83636551b6307cd816563a4a5539f17ac6b

5、配置跨域，进入容器内部，修改elasticsearch.yml

[root@iZwz99dhxbd6xwly17tb3bZ ~]# docker exec -it es /bin/bash

[root@c11ef1beb4f3 elasticsearch]# ls

LICENSE.txt  NOTICE.txt  README.textile  bin  config  data  lib  logs  modules  plugins

[root@c11ef1beb4f3 elasticsearch]# cd config/

[root@c11ef1beb4f3 config]# ls

elasticsearch.keystore  ingest-geoip  log4j2.properties  roles.yml  users_roles

elasticsearch.yml       jvm.options   role_mapping.yml   users

[root@c11ef1beb4f3 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@iZwz99dhxbd6xwly17tb3bZ ~]# docker restart es

es

7、浏览器访问ip:9200

{

  "name" : "bfc29f5a8f8c",

  "cluster_name" : "docker-cluster",

  "cluster_uuid" : "9dtJwBrNTwCHnbewPETxhw",

  "version" : {

    "number" : "7.1.1",

    "build_flavor" : "default",

    "build_type" : "docker",

    "build_hash" : "7a013de",

    "build_date" : "2019-05-23T14:04:00.380842Z",

    "build_snapshot" : false,

    "lucene_version" : "8.0.0",

    "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@iZwz99dhxbd6xwly17tb3bZ ~]# docker pull mobz/elasticsearch-head:5

Trying to pull repository docker.io/mobz/elasticsearch-head ...

5: Pulling from docker.io/mobz/elasticsearch-head

Digest: sha256:55a3c82dd4ba776e304b09308411edd85de0dc9719f9d97a2f33baa320223f34

Status: Downloaded newer image for docker.io/mobz/elasticsearch-head:5

2、运行ElasticSearch-Head容器

[root@iZwz99dhxbd6xwly17tb3bZ ~]# docker run -d --name es_admin -p 9100:9100 mobz/elasticsearch-head:5

76b0903ac01bc642d4d3ad238134df7312473a44c5b9f603f97f6742a759e629

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@iZwz99dhxbd6xwly17tb3bZ ~]# docker exec -it es /bin/bash

[root@970f612c5cac elasticsearch]# ls

LICENSE.txt  NOTICE.txt  README.textile  bin  config  data  lib  logs  modules  plugins

[root@970f612c5cac elasticsearch]# cd plugins/

[root@970f612c5cac plugins]# mkdir ik

[root@970f612c5cac plugins]# ls

ik  ingest-geoip  ingest-user-agent

2、下载与es对应版本的ik压缩包，并解压

这一步有的人服务器不支持zip所以解压不了。我是从电脑上解压后弄成tar.gz文件上传到服务器然后cp到容器内部对应文件夹下，命令 docker cp /tmp/elasticsearch-analysis-ik-7.1.1.tar.gz 40aeef081297:/usr/share/elasticsearch/plugins/tk

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

[root@970f612c5cac plugins]# cd ik

[root@970f612c5cac ik]# wget https://github.com/medcl/elasticsearch-analysis-ik/releases/download/v7.1.1/elasticsearch-analysis-ik-7.1.1.zip

[root@970f612c5cac ik]# unzip elasticsearch-analysis-ik-7.1.1.zip

[root@970f612c5cac ik]# ls

commons-codec-1.9.jar    elasticsearch-analysis-ik-6.3.2.jar  plugin-descriptor.properties

commons-logging-1.2.jar  httpclient-4.5.2.jar                 plugin-security.policy

config                   httpcore-4.4.4.jar

3、退出容器，重启es容器

[root@970f612c5cac ik]# exit

exit

[root@iZwz99dhxbd6xwly17tb3bZ ~]# docker restart 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": "这是我拷贝来的,我是不是很厉害"
}

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，从中我们可以清晰感受到Docker的强大之处！
