无法更改elasticsearch配置中的Path.Data

Question

我不能改变本地ES索引位置-不能修改path.data。

# path.data: /var/lib/elasticsearch'
path.data: /run/media/admin/bvv2/elasticsearch/

Job for elasticsearch.service failed because the control process exited with error code. See "systemctl status elasticsearch.service" and "journalctl -xe" for details.

我遇到了类似的错误，它是由不正确的父目录权限引起的。

其中一个父目录不允许其他unix用户访问该目录，更具体地说，该目录的权限是drwx--x--+。Elasticsearch在将权限更改为drwx--x--x+(CHMOD711)后启动。你也可以试试。
