elk add node solved unassigned shards

问题
因为之前搭建ELK是单机单节点，运行了一段时间了，今天上服务器查看了下状态，命令如下
$ curl -XGET "http://localhost:9200/_cat/health?v"
突然发现status: yellow，奇怪的是出现了大量unassigned shards。 已经搜索了一下相关资料，都建议新增节点试试，可以解决这个问题；经过尝试，果然解决了这个问题，顺便把搭建过程重新整理一遍（ [查看之前整理的](http://www.zshuiquan.com/archives/20161213-elk-notes.html) ）
