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/elasticsearch latest 5acf0e8da90b 3 days ago 486 MB
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！
