elasticsearch学习(1)

安装 elasticsearch ,操作elasticsearch的工具kibana,

(1)在kibana中输入GET _cluster/health查看es的健康状况(2)在kibana中输入 GET /_cat/health?v 查看es具体信息

epoch      timestamp cluster       status node.total node.data shards pri relo init unassign pending_tasks max_task_wait_time active_shards_percent
1565201059 18:04:19  elasticsearch green           1         1      2   2    0    0        0             0                  -                100.0%

status :green:每个索引的primary shard 和replica shard 都是active状态

   yellow:每个索引的primary shard 都是active状态的,但是部分replica shard不是active状态的

  red:不是所有索引primary shard都是active状态的,部分索引有数据丢失了

 

kibana中:GET /_cat/indices?v
