docker安装elasticsearch+elasticsearch-head+analysis-ik分词

1、用 Docker 拉取ElasticSearch镜像

[root@iZwz9d6z27o4s0t3dzfydlZ dnmp]# docker pull elasticsearch:7.9.0
7.9.0: Pulling from library/elasticsearch
75f829a71a1c: Pull complete
372e2d4c0ddd: Pull complete
8198cfd92e19: Pull complete

Status: Downloaded newer image for elasticsearch:7.9.0
docker.io/library/elasticsearch:7.9.0

2、运行es容器：

docker run -d --name elasticsearch -p 9200:9200 -p 9300:9300 -e "discovery.type=single-node" -e ES_JAVA_OPTS="-Xms128m -Xmx128m" -v /root/dnmp/logs/es/:/usr/share/elasticsearch/logs 0eddd30d8bdf

3、访问http://xxxxxx:9200/ 是否安装成功

4、设置允许跨域访问（为了elasticsearch-head连接访问）

进入容器：docker exec -it elasticsearch /bin/bash
vi /config/elasticsearch.yml 
添加：http.cors.enabled: true
http.cors.allow-origin: "*"
退出exit:
重启：docker restart elasticsearch

5、安装elasticsearch-head 可以用 docker search elasticsearch-head 搜索镜像，如图： 拉去对应版本的镜像：本来想拉去对应es7.9的版本

[root@iZwz9d6z27o4s0t3dzfydlZ dnmp]# docker pull mobz/elasticsearch-head:7
Error response from daemon: manifest for mobz/elasticsearch-head:7 not found: manifest unknown: manifest unknown

进hub.docker.com看es-head看tag最高才5，只能拉取对应5的版本了 https://hub.docker.com

[root@iZwz9d6z27o4s0t3dzfydlZ dnmp]# docker pull mobz/elasticsearch-head:5

6、安装ik分词

首先在宿主机下载：
wget https://github.com/medcl/elasticsearch-analysis-ik/releases/download/v7.9.0/elasticsearch-analysis-ik-7.9.0.zip
进入容器es： docker exec -it elasticsearch /bin/bash
查看[root@b7a01259e823 plugins]# pwd
/usr/share/elasticsearch/plugins
exit;

把压缩包拷贝到容器内
docker cp elasticsearch-analysis-ik-7.9.0.zip elasticsearch:/usr/share/elasticsearch/plugins
进去容器plugins目录解压： 
unzip elasticsearch-analysis-ik-7.9.0.zip -d ik7.9
 rm -rf elasticsearch-analysis-ik-7.9.0.zip
重启es容器：docker restart elasticsearch

用postman查看分词是否成功：
