集群管理

（1）GET /_cat/health?vgreen //每个索引的primary shard 和replica shard 都是active
yellow //每个primary shard 都是active状态的，但是部分replica shard 不是active 
red //不是所有primary shard 都是active 状态

(2)查看集群中有那些索引
GET /_cat/indices?v
health status index   uuid                   pri rep docs.count docs.deleted store.size pri.store.size
yellow open   .kibana DfpotP-7RLSZUW981Na7Lg   1   1          1            0      3.1kb          3.1kb

（3）创建索引 PUT /test_index?pretty
（4）删除索引 DELETE /test_index?pretty
