添加x-pack插件后弹性搜索服务停止[无法加载插件类[org.elasticsearch.xpack.XPackPlugin]

时间：2017-01-26 12:48:06

标签： elasticsearch kibana xpack

我正在使用Elastic stack 5.1。

我安装了弹性搜索和kibana，并安装了xpack， 他们正在工作。我还按照所需的安装顺序安装了logstash和beats。

安装节拍后，在我的公司VPN和代理进行一些更改后，我的elasticsearch和kibana停止工作，服务甚至没有启动。

我删除了让ES和kibana工作的x-pack，但是当我安装x-pack时，ES和kibana再次停止工作。我该怎么办？

日志说无法加载xpack插件：

1 个答案:

答案 0 :(得分：0)

所以我能解决这个问题。

ls -al / etc / elasticsearch / x-pack / system_key -rw ------- 1 root elasticsearch 128 Nov 14 16:21 / etc / elasticsearch / x-pack / system_key

chown elasticsearch / etc / elasticsearch / x-pack / system_key

看起来elasticsearch-plugin命令以root身份安装了x-pack插件，而elasticsearch本身没有读取此文件的权限。
