问题

1.Elasticsearch启动失败，错误提示如下

systemctl status elasticsearch

Sep 25 20:40:56 elasticsearch systemd[1]: elasticsearch.service: Start operation timed out. Terminating.
Sep 25 20:40:57 elasticsearch systemd[1]: elasticsearch.service: Failed with result 'timeout'.
Sep 25 20:40:57 elasticsearch systemd[1]: Failed to start Elasticsearch.

修改启动超时时间

/usr/lib/systemd/system/elasticsearch.service

TimeoutStartSec=500

2.创建文档时报以下错误:

json

{"error":{"root_cause":[{"type":"cluster_block_exception","reason":"index [logging] blocked by: [FORBIDDEN/12/index read-only / allow delete (api)];"}],"type":"cluster_block_exception","reason":"index [logging] blocked by: [FORBIDDEN/12/index read-only / allow delete (api)];"},"status":403}

检查磁盘空间是否已满，清理空间
