请注意，在我更新证书之前，整个集群都运行良好。我在使用 Elasticsearch 7.5。
我使用 certificate-util 更新了我的证书 - 创建了一个包含我所有服务器和 Kibana 节点的 server.yml，使用 -pem、-multiple 和 --keep-ca-key 运行该实用程序，传递了 ca.crt以及发送给节点的各种节点证书，确保 elasticsearch.yml 和 kibana.yml 文件适当地指向它们，并进行滚动重启。然后一切都崩溃了。
主要问题——我目前至少遇到的问题——是我在主题中遇到了错误。完整的，来自与之通信的 Elastic 节点的日志：

我所有的节点都给出了类似的错误。
从表面上看，它看起来相当简单 - 你会认为 ca.crt 在 Kibana 节点上是错误的（至少，这是我从搜索中发现的。）如果它是错误的，我不知道为什么 - 它实际上是与我在所有其他节点上获得的 ca.crt 相同。
据我所知，我没有明确配置密钥库，elasticsearch-keystore 的输出如下所示：
[root@Kibana Node kibana]# /usr/share/elasticsearch/bin/elasticsearch-keystore list
bootstrap.password
keystore.seed
xpack.security.authc.realms.active_directory.platform_ad.secure_bind_password
如果 Java 有一个密钥库，我也找不到它，至少找不到名称“keystore”——如果有人知道可以在哪里配置它，下一步可能会很好。
我不确定我还能做些什么来解决问题 - 我的 Google-fu 让我失望了（我发现的一切都指向 CA 确实是问题，以最简单的方式 - 它们不匹配。如果在这种情况下它们不匹配，这是证书实用程序的错误，但将它们与 openssl 进行比较并没有发现任何差异。）
快速总结：用于为集群生成所有证书的同一个 ca.crt 在 Kibana 上似乎不受信任，但似乎在其他节点上工作。
