elasticsearch在黃色狀態

Question

我有一個雙節點彈性搜索集羣logstash和kibana。在我開始logstash之前，羣集處於綠色狀態，elasticsearch羣集變爲黃色狀態。 運行curl -XGET http://localhost:9200/_cat/shards?pretty 將呈現以下

我怎樣才能獲得集羣早在綠色的狀態？

Answer 1

黃色表示您有未分配的分片，如輸出所示。

確保您的碎片分配啓用：

curl -XPUT localhost:9200/_cluster/settings -d '{ 
    "transient" : { 
     "cluster.routing.allocation.enable" : "all" 
    } 
}' 

您也可以嘗試迫使碎片上的一個節點：
