使用

安装 docker 和 docker-compose

执行命令 docker-compose up -d

打开 chrome 浏览器的插件 ElasticSearch Head, 效果如下图

![这里写图片描述][70]

本例子选择了 es 和 es1 为 master   
若想方便看日志, 也可将 logs 挂载出来, 例如在 docker-compose.yml 中 es 的 volumes 加上   
\- ./logs/es/:/usr/share/elasticsearch/logs/:rw   
同理 data 挂载出来可加上   
\- ./data/es/:/usr/share/elasticsearch/data/:rw
