搭建一个elasticsearch6.5.0集群环境，再把elasticsearch-head插件和ik分词器装好，在docker环境下完成这些工作需要多久？

答案是：只需下面这一行命令：

[code]<span style="color:#000000"><code class="language-shell"><span style="color:#61aeee">wget</span> https://raw.githubusercontent.com/zq2599/blog_demos/master/elasticsearch_docker_compose/docker-compose.yml <span style="color:#669900">&&</span> \
docker-compose up -d
</code></span>

接下来就试试这一行命令吧；

环境信息

1. 操作系统：CentOS 7.6
2. docker：17.03.2-ce
3. docker-compose：version 1.23.2
4. elasticsearch：这里选用的是6.5.0版本的elasticsearch，因为目前ik分词器官方最高只支持到6.5.0版本

验证

1. 在上述环境下，输入上面提到的那行命令，即可创建elasticsearch6.5.0集群环境，如下：

1. 假设docker所在电脑的IP地址是192.168.1.101，如下图，浏览器访问此地址可以查看es信息：http://192.168.1.101:9200
   
2. 如下图，浏览器访问此地址可以使用head插件：http://192.168.1.101:9100
   
3. 执行以下命令来创建一个索引：

[code]<span style="color:#000000"><code class="language-shell"><span style="color:#61aeee">curl</span> -X PUT http://192.168.1.101:9200/test001

1. 执行以下命令验证ik分词器效果：

[code]<span style="color:#000000"><code class="language-shell"><span style="color:#61aeee">curl</span> -X POST \
<span style="color:#669900">'http://192.168.1.101:9200/test001/_analyze?pretty=true'</span> \

验证完毕，集群、head插件、ik分词器都是正常的；

1. 首先来看看docker-compose.yml文件的内容，这里面决定了整个构成整个功能的容器：

1. 上述yml文件中，使用了镜像bolingcavalry/elasticsearch-head:6来实现head插件，关于此镜像的细节，请参考《自己动手制作elasticsearch-head的Docker镜像》；
2. 上述yml文件中，使用了镜像bolingcavalry/elasticsearch-with-ik:6.5.0来集成ik分词器，关于此镜像的细节，请参考《自己动手制作elasticsearch的ik分词器的Docker镜像》；

希望这一行简单的命令能帮助您快速搭建所需的elasticsearch环境；
