同样，我在使用 Solr 时遇到了一些问题。我正在尝试设置一个包含三个 ZooKeeper 实例和两个 Solr 实例的 SolrCloud 集群。应使用 SSL 保护通信。我使用官方 Solr wiki 作为手册:https://cwiki.apache.org/confluence/display/solr/Enabling+SSL
当我启动第一个 Solr 节点时，一切正常。我可以通过 HTTPS 访问 Web UI，并且 Solr 和 ZooKeeper 之间的通信也有效。但是当我启动集群中的第二个 Solr 节点时，出现以下异常:

看来Solr不接受自签名证书。 Solr Wiki 中所述的选项 -Dsolr.ssl.checkPeerName=false 无效(我将此参数放在 solr.in.sh 脚本中)。我不得不承认我现在很无能:(
有谁知道我可以做些什么来使 Solr 节点间通信正常工作？
顺便说一句:我使用的是 Solr 6.1.0，在我激活 SSL 之前，一切都运行良好。
非常感谢!
最佳答案
您还可以通过以下命令将第二个节点的证书添加到第一个节点的 keystore ，并将第一个节点的证书添加到第二个节点的 keystore :
keytool -import -alias ca -file other_node_cert -keystore solr-ssl.keystore.jks
然后就可以使用自签名证书了。
关于ssl - 使用 SSL 的 Solr 节点间通信，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/38228425/
