[ElasticSearch]常用URL路径

https://127.0.0.1:9200/
http://127.0.0.1:9200/_all?pretty

https://127.0.0.1:9200/_cluster/health?pretty
https://127.0.0.1:9200/_cat/health?v&pretty&h=status
status的意义:
+ green 绿灯: 所有分片都正确运行，集群非常健康。
+ yellow 黄灯: 所有主分片都正确运行，但是有副本分片缺失。
这种情况意味着 ES 当前还是正常运行的，但是有一定风险。
注意，在 Kibana4 的 server 端启动逻辑中，即使是黄灯状态，Kibana 4 也会拒绝启动，死循环等待集群状态变成绿灯后才能继续运行。
+ red 红灯: 有主分片缺失。这部分数据完全不可用。而考虑到 ES 在写入端是简单的取余算法，轮到这个分片上的数据也会持续写入报错。
