ElasticSearch是一个基于Lucene的搜索服务器。它提供了一个分布式多用户能力的全文搜索引擎，基于RESTful web接口。Elasticsearch是用Java开发的，并作为Apache许可条款下的开放源码发布，是当前流行的企业级搜索引擎。
我们建立一个网站或应用程序，并要添加搜索功能，但是想要完成搜索工作的创建是非常困难的。只看数据库的查找不仅极耗资源，而且速度不快。elasticsearch是一个不错的选择，不仅快，还具有实时性。
下面讲解安装步骤，分两种，一种是在线下载，另一种是离线本地下载。

- 运行镜像
docker run -d -p 9200:9200 -p 9300:9300 --name search elasticsearch:2.4.4
- 查看正在运行的容器，验证开启
docker ps
- 再次验证是否安装成功
curl 127.0.0.1：9200
显示如下图：

离线下载
- 可在网盘中下载压缩包，下载后通过rz或其他方法传入Linux中。https://pan.baidu.com/s/1bbiv73O8kH7S66fxbyFUOg
- 导入镜像
docker load -i elasticsearch-ik-2.4.6_docker.tar- 解压配置文件
unzip elasticsearch.zip- 打开配置文件elasticsearch/config/elasticsearch.yml ，查看以下两处地方是否已修改
# network.host: 172.18.168.123
network.host: 0.0.0.0
#
# Set a custom port for HTTP:
#
http.port: 8002- 创建docker容器并运行
docker run -dti --network=host --name=elasticsearch -v /home/bd/elasticsearch/config:/usr/share/elasticsearch/config delron/elasticsearch-ik:2.4.6-1.0这里的代码不要直接复制， -v /home/bd/elasticsearch/config表示我配置文件的路径，你的路径需要自己对应。
- 查看是否创建成功
docker container ls -a
- 运行如下命令，如果有显示则elasticsearch配置成功
curl 127.0.0.1:8002
安装Head插件
- 进入容器
docker exec -it c04e4bfa058e /bin/bash
- 到/bin目录
cd bin- 执行plugin命令
plugin install mobz/elasticsearch-head
- 到浏览器输入127.0.0.1：8002/_plugin/head/，结果如下：
