Search Guard使用SSL连接到远程Elasticsearch集群

Question

使用过this指南来创建SSL证书

我正在尝试连接到远程Elasticsearch集群。两个群集都使用SSL证书（由同一CA签名），可以吗？

本地集群：

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", "ekl2.test2.com"]


discovery.zen.minimum_master_nodes: 1

xpack.security.enabled: false


searchguard.ssl.transport.pemcert_filepath: '/etc/elasticsearch/ssl/node1.pem'
searchguard.ssl.transport.pemkey_filepath: 'ssl/node1.key'
searchguard.ssl.transport.pemtrustedcas_filepath: '/etc/elasticsearch/ssl/root-ca.pem'
searchguard.ssl.transport.enforce_hostname_verification: false
searchguard.ssl.transport.resolve_hostname: false
searchguard.ssl.http.enabled: true
searchguard.ssl.http.pemcert_filepath: '/etc/elasticsearch/ssl/node1_http.pem'
searchguard.ssl.http.pemkey_filepath: '/etc/elasticsearch/ssl/node1_http.key'
searchguard.ssl.http.pemtrustedcas_filepath: '/etc/elasticsearch/ssl/root-ca.pem'
searchguard.nodes_dn:
- CN=ekl.test.com,OU=Ops,O=BugBear BG\, Ltd.,DC=BugBear,DC=com
- CN=ekl1.test1.com,OU=Ops,O=BugBear BG\, Ltd.,DC=BugBear,DC=com
searchguard.authcz.admin_dn:
- CN=admin.test.com,OU=Ops,O=BugBear Com\, Inc.,DC=example,DC=com

远程集群：

cluster.name: client2
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

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



http.port: 9200


discovery.zen.ping.unicast.hosts: ["ekl6.test1.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.ssl.transport.pemkey_filepath: 'ssl/node2.key'
searchguard.ssl.transport.pemtrustedcas_filepath: '/etc/elasticsearch/ssl/root-ca.pem'
searchguard.ssl.transport.enforce_hostname_verification: false
searchguard.ssl.transport.resolve_hostname: false
searchguard.ssl.http.enabled: true
searchguard.ssl.http.pemcert_filepath: '/etc/elasticsearch/ssl/node2_http.pem'
searchguard.ssl.http.pemkey_filepath: '/etc/elasticsearch/ssl/node2_http.key'
searchguard.ssl.http.pemtrustedcas_filepath: '/etc/elasticsearch/ssl/root-ca.pem'
searchguard.nodes_dn:
- CN=ekl.test.com,OU=Ops,O=BugBear BG\, Ltd.,DC=BugBear,DC=com
- CN=ekl1.test1.com,OU=Ops,O=BugBear BG\, Ltd.,DC=BugBear,DC=com
searchguard.authcz.admin_dn:
- CN=admin.test.com,OU=Ops,O=BugBear Com\, Inc.,DC=example,DC=com
Certificates are self-signed

我可以从本地服务器卷曲到远程群集。

 curl -vX GET "https://admin:Pass@ekl1.test1.com:9200"

我在Kibana GUI中添加了远程域：ekl1.test1.com:9200

并在ES日志中得到此错误：

  

RemoteClusterConnection] [4P1fXFO]从外部群集> [client2]获取节点失败   org.elasticsearch.transport.ConnectTransportException：[] [172.31.37.123:9200]> handshake_timeout [30s]

Answer 1

通过在Kibana界面中指定端口9300而不是9200来解决

和

http.cors.enabled: true
http.cors.allow-origin: "*"
