解决Elasticsearch索引只读

ddn

今天添加索引时发现 kibana 添加索引不生效, 页面也没有报错，没有创建成功只是一闪而过。

另外发现各项目日志与当前时间差异很大,filebeat 一直报错 io timeout

具体报错如下:

filebeat 无法给 logstash 传输数。

ip 使用 x 代替 

logstash/async.go:235   Failed to publish events caused by: read tcp 172.17.x.x:39092->172.17.x.x:5044: i/o timeout

logstash 报错如下，logstash 无法给 es 传输数据，es 一直在拒绝所有的请求 

[INFO][logstash.outputs.elasticsearch] Retrying individual bulk actions that failed or were rejected by the previous bulk request. {:count=>1}
[INFO][logstash.outputs.elasticsearch] retrying failed action with response code: 403 ({"type"=>"cluster_block_exception", "reason"=>"blocked by: [FORBIDDEN/12/index read-only / allow delete (api)];"})

报错索引只读 

index read-only / allow delete (api)];"}

es 报错，es 报错也是索引只读错误

解决办法 1
在 kibana 开发控制台执行下面语句即可 

PUT _settings
    {
    "index": {
    "blocks": {"read_only_allow_delete": "false"}
    }
    }

解决方法 2

如果 kibana 无法执行命令，可以使用下面命令解决 

curl -XPUT -H "Content-Type: application/json" http://localhost:9200/_all/_settings -d '{"index.blocks.read_only_allow_delete": null}'

一旦在存储超过 95%的磁盘中的节点上分配了一个或多个分片的任何索引，该索引将被强制进入只读模式

如图所示

再次查看日志信息，问题成功解决！
