ElasticSearch 報錯 failed to obtain node locks

failed to obtain node locks, tried [[/var/lib/elasticsearch]] with lock id [0];

錯誤信息：

failed to obtain node locks, tried [[/var/lib/elasticsearch]] with lock id [0]; maybe these locations are not writable or multiple nodes were started without increasing [node.max_local_storage_nodes]

Elasticsearch version 6.8.2

解決方法一：

查找ES進程號，殺掉進程然后重啟。

ps -ef | grep elastic

kill -9 進程號

解決方法二：

給予操作ES的管理員權限，chown -R 用戶名:組名 文件目錄 

chown -R elastic /var/lib/elasticsearch/

解決方法三：

可能是因為安裝了ES的插件，修改了配置文件 elasticsearch.yml

將這些注釋或刪除掉后重啟
