elasticsearch health yellow

elasticsearch 状态查看：health为 yellow的解决办法

[elasticsearch@test01 logstash-6.3.1]$ curl 'localhost:9202/_cat/indices?v'

结果：

health	status	index	pri	rep	docs.count	docs.deleted	store.size	pri.store.size
yellow	open	.kibana	1	1	1	0	3.1kb	3.1kb
yellow	open	info	5	1	19485	0	87.2mb	87.2mb

[elasticsearch@test01 config]$ curl -XGET http://localhost:9202/_cluster/health?pretty=true

结果：

{
  "cluster_name" : "elasticsearch",
  "status" : "yellow",
  "timed_out" : false,
  "number_of_nodes" : 1,
  "number_of_data_nodes" : 1,
  "active_primary_shards" : 6,
  "active_shards" : 6,
  "relocating_shards" : 0,
  "initializing_shards" : 0,
  "unassigned_shards" : 6,
  "delayed_unassigned_shards" : 0,
  "number_of_pending_tasks" : 0,
  "number_of_in_flight_fetch" : 0,
  "task_max_waiting_in_queue_millis" : 0,
  "active_shards_percent_as_number" : 50.0
}

使用命令调整

curl -H "Content-Type: application/json" -XPUT 'http://localhost:9202/_settings' -d '
{
    "index" : {
        "number_of_replicas" : 0
    }
}'

更改后，再查询

[elasticsearch@test01 config]$ curl -XGET http://localhost:9202/_cluster/health?pretty=true

结果：

{
  "cluster_name" : "elasticsearch",
  "status" : "green",
  "timed_out" : false,
  "number_of_nodes" : 1,
  "number_of_data_nodes" : 1,
  "active_primary_shards" : 6,
  "active_shards" : 6,
  "relocating_shards" : 0,
  "initializing_shards" : 0,
  "unassigned_shards" : 0,
  "delayed_unassigned_shards" : 0,
  "number_of_pending_tasks" : 0,
  "number_of_in_flight_fetch" : 0,
  "task_max_waiting_in_queue_millis" : 0,
  "active_shards_percent_as_number" : 100.0
}

[elasticsearch@test01 config]$ curl 'localhost:9202/_cat/indices?v'
