查看ES各个分片的状态

$ curl -XGET http://127.0.0.1:9200/_cluster/health?pretty
{
  "cluster_name" : "elasticsearch_brew",
  "status" : "yellow",
  "timed_out" : false,
  "number_of_nodes" : 1,
  "number_of_data_nodes" : 1,
  "active_primary_shards" : 350,
  "active_shards" : 350,
  "relocating_shards" : 0,
  "initializing_shards" : 0,
  "unassigned_shards" : 3,
  "number_of_pending_tasks" : 0,

}

Elasticsearch单台，增加kibana监控，集群状态总是黄色，索引kibana副本有问题，我ES里设置了一个

直接执行下列命令，删除多余副本

curl -XPUT "http://localhost:9200/_settings" -d'
{
  "number_of_replicas" : 0
}'
