Elastic search AccessDeniedException[/usr/share/elasticsearch/data/nodes/0] -- 访问被拒绝错误

Question

我正在尝试使用 nfs mount 作为我的 elasticsearch 数据目录，之前我使用的是主机存储。但是当我尝试打开我的容器时，我遇到了下面提到的错误：

 ElasticsearchException[failed to bind service]; nested: AccessDeniedException[/usr/share/elasticsearch/data/nodes/0];

我之前使用 docker-compose 时，我的集群工作正常，当我使用主机存储时，但当我尝试切换到 NFS 存储时，我遇到了上述错误。下面是我的 docker-compose 文件：

version: '3.3'
volumes:
  data:
    driver: local
    driver_opts:
       type: nfs
       device: ":/data1/elasticsearch_data"
       o: addr=10.10.15.46,rw
#volumes:

    network_mode: "host"
    labels:
      org.label-schema.group: "APM-monitoring"
    healthcheck:
      test: ["CMD", "curl", "--write-out", "'HTTP %{http_code}'", "--silent", "--output", "/dev/null", "http://es02:9200/"]
      retries: 10
      interval: 10s

这是我的目录权限和位置

到目前为止我已经尝试过：

chown 1000:1000 elasticsearch_data（照片中提到的 vimzy 用户的 1000 uid）。

我在 docker-compose 中尝试过priviliged=true。除此之外，还尝试了多种方法来解决权限被拒绝的问题。

任何帮助...

Answer 1

由于指定路径的权限问题而发生此错误。

将路径从 更改/usr/share/elasticsearch/data为/var/lib/elasticsearch/data

会起作用的！

Answer 2

这解决了我的问题

sudo chown -R 1000:root docker_data

Answer 3

可能与 NFSv3 不兼容，请尝试切换到 NFSv4，如本博客中所述：
