Hello. Per
https://solr.apache.org/guide/8_11/solr-system-requirements.html
https://solr.apache.org/guide/8_11/enabling-ssl.html
I am trying to take Solr 8.11.1 to production on a CentOS 7 cloud VPS.
Solr 8.11.1 is working fine (SSL-secured; authentication via security.json;
etc.) on my Arch Linux local host.
I installed Solr 8.11.1 via solr.in.sh, and tried it with Java JRE 1.8 (details
below) and java-11-openjdk.x86_64.
java-11-openjdk.x86_64 ##
/usr/lib/jvm/java-11-openjdk-11.0.16.0.8-1.el7_9.x86_64/bin/java
java-1.8.0-openjdk.x86_64 ##
/usr/lib/jvm/java-1.8.0-openjdk-1.8.0.342.b07-1.el7_9.x86_64/jre/bin/java
Solr worked with the Java 11 OpenJDK, but I was unable to SSL-secure it.
Solr also works on the Java 1.8 JRE, but complains
HTTP/2 + SSL is not support in Java 8.
Configure Solr with HTTP/1.1 + SSL
How can I resolve this issue?
