SSL的单节点间通信

Question

同样，我在Solr方面遇到一些问题。 我正在尝试使用三个ZooKeeper实例和两个Solr实例设置一个SolrCloud集群。 通信应使用SSL保护。 我使用了官方的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HTTP S访问Web UI，Solr和ZooKeeper之间的通信也可以。 但是，当我在集群中启动第二个Solr节点时，出现以下异常：

因此，似乎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知:(

有谁知道如何使Solr节点之间的通信正常进行？

顺便说一句：我使用的是Solr 6.1.0，在激活SSL之前，一切都像个魅力。

非常感谢！

Answer 1

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密钥库中，也可以将第一个节点的证书添加到第二个节点的密钥库中：

keytool -import -alias ca -file other_node_cert -keystore solr-ssl.keystore.jks

然后，您可以使用自签名证书。

Answer 2

查看异常详细信息，这似乎是Java客户端代码和启用ssl的服务器之间的握手问题。 此处涉及的JRE可能不信任证书。 您可以尝试将证书标记为受信任的证书（包括在JRE信任库中）。 检查特定于JRE版本的文档，以获取更新信任库的步骤。
