ElasticSearch 报错 failed to obtain node locks

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

错误信息：

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

解决方法一：

查找ES进程号，杀掉进程然后重启。

ps -ef | grep elastic

kill -9 进程号

解决方法二：

给予操作ES的管理员权限，chown -R 用户名:组名文件目录

chown -R elastic /var/lib/elasticsearch/

解决方法三：

可能是因为安装了ES的插件，修改了配置文件 elasticsearch.yml

将这些注释或删除掉后重启
