即使存在读取权限,Elasticsearch 也无法启动并出现“权限读取”错误

即使存在读取权限,Elasticsearch 也无法启动并出现“权限读取”错误

我有一个符号链接指向Ubuntu 16.04 LTS Azure VM 上/etc/elasticsearch/analysis已安装的驱动器。/elasticdata/fileshare/analysis当我尝试启动 elasticsearch 时,出现以下权限错误:

Caused by: java.security.AccessControlException: access denied ("java.io.FilePermission" "/etc/elasticsearch/analysis" "read")

挂载的驱动器具有以下权限:
drwxrwxrwx 2 elasticsearch elasticsearch 0 May 22 22:44 analysis

符号链接具有以下权限:

lrwxrwxrwx 1 elasticsearch elasticsearch    43 May 22 22:49 analysis -> /elasticdata/fileshare/analysis/

TLDR:符号链接由用户和组拥有elasticsearch,似乎具有读取权限,但我在 elasticsearch 启动时仍然收到读取权限错误。

如何解决此权限错误?

编辑:

以下是路径中每个步骤的权限:

/etc => drwxr-xr-x
/etc/elasticsearch => drwxr-S---
/etc/elasticsearch/analysis => lrwxrwxrwx
/elasticdata => drwxrwxrwx
/elasticdata/fileshare => drwxrwxrwx
/elasticdata/fileshare/analysis => drwxrwxrwx

答案1

您需要验证路径中每个步骤的权限以及符号链接的目标:

/etc
/etc/elasticsearch
/etc/elasticsearch/analysis
/elasticdata
/elasticdata/fileshare
/elasticdata/fileshare/analysis
