解决问题 org.elasticsearch.cluster.block.ClusterBlockException: blocked by: [FORBIDDEN/12/index read-o

ES部署一段时间后，今天发布内容发现后台报错

再网上搜索都是ES集群部署会出现这个问题，这边单机部署，不知道为什么会有这个问题。

按照 Eleastisearch 官方文档给的解决办法是

An example of resetting the read-only index block on the twitter index:

PUT /twitter/_settings
{
“index.blocks.read_only_allow_delete”: null
}

经研究学习，在Elasticsearch所部署的机器上，执行以下命令，可解决此问题：

curl -XPUT -H "Content-Type: application/json" http://127.0.0.1:9200/_all/_settings -d '{"index.blocks.read_only_allow_delete": null}'

其中 _all 这个可以更改为自己在创建 Eleastisearch 索引的时候的name，用来修改单个索引只读状态，当然用 _all 也可以, _all 是修改了所有的索引只读状态。
