Question

我有一个带有logstash和kibana的两节点elasticsearch集群。群集处于绿色状态，直到我启动了logstash，弹性搜索群集变为黄色状态。正在运行curl -XGET http://localhost:9200/_cat/shards?pretty 将显示以下内容

如何让群集恢复绿色状态？

Answer 1

黄色表示您有未分配的分片，如输出所示。

确保您的分片分配已启用：

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

您还可以尝试将分片强制转换为节点：
