Останов службы сервиса asticsearch после добавления плагина x-pack [Не удалось загрузить класс плагина [org.elasticsearch.xpack.XPackPlugin]

Question

Я использую Elastic Stack 5.1.

У меня были эластичный поиск и кибана с установленным на них xpack,и они работали. Я также установил logstash и биты, в необходимом порядке установки.

После установки ударов и после некоторых изменений в моей компании VPN и прокси перестали работать мой asticsearch и kibana, сервис даже не запускается.

Я удалил x-pack, который заставил работать ES и kibana, но снова, когда я установил x-pack, ES и kibana перестали работать. Что я должен делать?

В журнале говорится, что плагин xpack не может быть загружен:

Answer 1

Так что я смог это исправить..

ls -al / etc /asticsearch/x-pack/system_key -rw------- 1 корневой каталог поиска 128 ноября 14 16:21 /etc/asticsearch / x-pack / system_key

chownasticsearch / etc /asticsearch / x-pack / system_key

Похоже, что команда asticsearch-plugin установила плагин x-pack, так как сам root, а у Flexiblesearch нет доступа для чтения этого файла.
