inter-Solr-node communication with SSL

问题


Again, I have some problems with Solr. I'm trying to set up a SolrCloud cluster with three ZooKeeper instances and two Solr instances. Communication should be secured with SSL. I used the official Solr wiki as manual: https://cwiki.apache.org/confluence/display/solr/Enabling+SSL

When I start the first Solr node everything works fine. I can access the Web UI via HTTPS and communication between Solr and ZooKeeper also works. But when I start the second Solr node in my cluster I get the following exception:

So it seems that Solr does not accept the self-signed certificate. The option -Dsolr.ssl.checkPeerName=false as stated in the Solr Wiki has no effect (I put this parameter in the solr.in.sh script). I have to admit I'm pretty clueless right now :(

Does anyone have any idea what I could do to make the inter-Solr-node communication work?

BTW: I'm on Solr 6.1.0, and before I activated SSL everything worked like a charm.

Thanks a lot!


回答1:


You can also add second node's certificate to the first node's keystore and also add first node's certificate to the second node's keystore via following command:

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

Then you can use self-signed certificate.




回答2:


Looking at exception details it appears to be a handshake issue between java client code and the ssl enabled server. The JRE involved here probably doesn't trust the certificate. You can try to mark the cert as a trusted one (include in JRE truststore). Check JRE version specific documentation for steps to update truststore.
