集成Head插件

# 在elasticsearch 5.x版本以后不再支持直接安装head插件，而是通过访问http://ip:9200获取集群监控信息
# 使用插件之前，必须在elasticsearch的配置文件(config/elasticsearch.yml)添加允许跨域参数 http.cors.enabled: true 和 http.cors.allow-origin: "*"
docker run -itd --restart always --name elasticsearch-head -p 9100:9100 mobz/elasticsearch-head:5-alpine
