ping 期间发现的主节点不足 - Elasticsearch 集群自签名证书

Question

之后使用 SearchGuard 加密 ElasticSearch 集群中的节点

大师：

cluster.name: client1
searchguard.enterprise_modules_enabled: false


node.name: ekl.test.com
node.master: true
node.data: true
node.ingest: true


network.host: 0.0.0.0

#http.host: 0.0.0.0
network.publish_host: ["ekl1.test1.com","ekl.test.com"]



http.port: 9200


discovery.zen.ping.unicast.hosts: ["ekl.test.com", "ekl1.test1.com"]


discovery.zen.minimum_master_nodes: 1

xpack.security.enabled: false

节点：

cluster.name: client1
searchguard.enterprise_modules_enabled: false


node.name: ekl1.test.com
node.master: false
node.data: true
node.ingest: false


network.host: 0.0.0.0

network.publish_host: ["ekl1.test1.com","ekl.test.com"]



http.port: 9200


discovery.zen.ping.unicast.hosts: ["ekl.test.com", "ekl1.test1.com"]


discovery.zen.minimum_master_nodes: 1

xpack.security.enabled: false


searchguard.ssl.transport.pemcert_filepath: '/etc/elasticsearch/ssl/node2.pem'

searchguard.nodes_dn:

searchguard.authcz.admin_dn:
- CN=admin.test.com,OU=Ops,O=BugBear Com\, Inc.,DC=example,DC=com
Certificates are self-signed

从节点我可以通过主机名远程登录到端口 9200/9300 我可以 ping 和

curl -kvX GET "https://admin:pass@ekl.test.com:9200" 工作正常。节点错误：

[ekl1.test1.com] ping 期间发现主节点不足（找到 []，但需要 1），再次 ping

两个服务器名称都正确

我怀疑问题出在我将其导入受信任的根 CA 锚中的自签名证书中，但错误仍然存在。

如果我指定 IP 而不是主机名，则得到：

在 http 或传输请求中发现非法参数。这意味着一个节点正在尝试连接到另一个节点非节点证书（没有 OID 或 searchguard.nodes_dn 配置不正确）或某人是欺骗请求。

ES Config path is /etc/elasticsearch [2019-03-28T21:25:56,450][INFO ][c.f.s.s.DefaultSearchGuardKeyStore] >[ekl1.test1.com] OpenSSL not available (this is not an error, we simply >fallback to built-in JDK SSL) because of java.lang.ClassNotFoundException: >io.netty.internal.tcnative.SSL

Answer 1

找到了：不得不添加到非主：

transport.tcp.port: 9300
discovery.zen.ping.unicast.hosts: ["ekl.test.com:9300"]
transport.host: ekl1.test1.com
