ElasticSearch 无法加载插件(许可证模块)

Question

我必须使用离线说明加载 ElasticSearch 插件，但即使我完全打开文件的权限并以 root 身份运行，我似乎也遇到了权限错误!我也已删除并重新安装，但此错误是一致的。

我遇到了同样的异常，但是在安装和加载 之后x-pack Elasticsearch 5.2.1 上的插件:

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 plugins 文件夹的所有权:

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