elasticsearch 5.5.1安装命令：

docker pull elasticsearch:5.5.1

启动es：

docker run --name elasticsearch -p 9200:9200 -p 9300:9300 -e "discovery.type=single-node" -d elasticsearch:7.2.0

检查：

curl http://localhost:9200

或者在浏览器中打开http://localhost:9200这个网址，如果能看到以下信息则说明我们的es是已经安装好了的。

  "name" : "530dd7820315",
  "cluster_name" : "docker-cluster",
  "cluster_uuid" : "7O0fjpBJTkmn_axwmZX0RQ",
  "version" : {
    "number" : "5.5.1",
    "build_flavor" : "default",
    "build_type" : "docker",
    "build_hash" : "508c38a",
    "build_date" : "2019-06-20T15:54:18.811730Z",
    "build_snapshot" : false,

    "minimum_index_compatibility_version" : "6.0.0-beta1"
  },
  "tagline" : "You Know, for Search"
}

修改配置，解决跨域访问问题：

进入到容器中

docker exec -it elasticsearch /bin/bash
cd /usr/share/elasticsearch/config/
vi elasticsearch.yml

在elasticsearch.yml的文件末尾加上：

http.cors.enabled: true
http.cors.allow-origin: "*"

重启

docker restart elasticsearch

安装ik分词器：

cd /usr/share/elasticsearch/plugins/
elasticsearch-plugin install https://github.com/medcl/elasticsearch-analysis-ik/releases/download/v5.5.1/elasticsearch-analysis-ik-5.5.1.zip
exit
docker restart elasticsearch

检查

POST test/_analyze
{
  "analyzer": "ik_max_word",
  "text": "你好我是东邪Jiafly"
}
