Question

我必须使用脱机指令加载ElasticSearch插件，但即使我完全打开文件权限并以root身份运行，我看起来也会收到权限错误！我已经删除并重新安装，但此错误是一致的。

Answer 1

我遇到了同样的异常，但在Elasticsearch 5.2.1上安装和加载 x-pack 插件后：

Caused by: java.nio.file.AccessDeniedException: /usr/share/elasticsearch/plugins/x-pack/plugin-descriptor.properties

就我而言，我首先将 elasticsearch 用户添加到根组：

usermod -aG root elasticsearch

之后，只需要修改插件文件夹的所有权：

chown -R elasticsearch:elasticsearch /usr/share/elasticsearch/plugins/

Answer 2

感谢Val，简单的解决方案是在安装插件后，如果您使用的是Elastic的RPM安装，则需要快速更改所有权/组：

chown -R root:elasticsearch /usr/share/elasticsearch

ElasticSearch无法加载插件（许可证模块）
