Add 2nd Node to Confluence Datacenter cluster?

Question

I just setup the confluence datacenter on one server, its working fine. Now I need to add 2nd node to cluster. I have looked at all the steps on your website and it makes no sense to me. Do I need to install the application on the 2nd node 1st and then copy the install and local home directory from 1st node afterwards or do I just copy the folders from 1st node and some how start up the applications on 2nd node. Your instructions seems to miss a lot of steps, sorry if I should be aware, this is my 1st time working confluence.   This is all running on windows 2016 servers.  Also where are the windows instructions to install Synchrony in datacenter cluster?  I will install syncrony on same nodes as confluence.  I opened a ticket with attlasin, but i'm not sure support actually exist...

here are the steps that make no sense.
Add more Confluence nodes
4. Copy Confluence to second node
To copy Confluence to the second node:

Shut down Confluence on node 1
Shut down your application server on node 2, or stop it automatically loading web applications

Copy the installation directory from node 1 to node 2
Copy the local home directory from node 1 to node 2
If the file path of the local home directory is not the same on nodes 1 and 2 you'll need to update the <installation directory>/confluence/WEB-INF/classes/confluence-init.properties file on node 2 to point to the correct location.
Copying the local home directory ensures the Confluence search index, the database and cluster configuration, and any other settings are copied to node 2.

Hi Robert,

I understand you are frustrated with the time it's taking to add a second node to your Data Center instance. I checked out your support case and it looks like the new information posted here was not shared there so I had a look.

Researching the error you posted, I found this knowledge base article: Hazelcast CANNOT start on this node. No matching network interface found.

I look forward to hearing whether the article helps in your case.

Please attach the latest logs to your support ticket so the support engineers can investigate more thoroughly.

Thanks,

Ann

Hello Ann, i'm getting a bit frustrated here. So, i copied over the program folder and data folder to 2nd node. I started the confluence batch file on 1st node, website is up and running. I now started the confluence batch file one 2nd node, but it not loading and stopped at certain point. I have copied install info. I see errors about no matching network interface. The only thing I can think of causing issue, is i'm using a domain based service account on 2nd node, simply because the SHARED directory is on network file server and the local confluence server system account can't write to it. THis is taking me too much time to simply add a 2nd node. Any ideas based on logs below? thanks 03-Aug-2018 09:50:07.755 WARNING [main] org.apache.tomcat.util.digester.SetPropertiesRule.begin [SetPropertiesRule]{Server} Setting property 'debug' to '0' did not find a matching property. 03-Aug-2018 09:50:07.848 WARNING [main] org.apache.catalina.startup.SetAllPropertiesRule.begin [SetAllPropertiesRule]{Server/Service/Connector} Setting property 'debug' to '0' did not find a matching property. 03-Aug-2018 09:50:07.973 WARNING [main] org.apache.tomcat.util.digester.SetPropertiesRule.begin [SetPropertiesRule]{Server/Service/Engine} Setting property 'debug' to '0' did not find a matching property. 03-Aug-2018 09:50:07.973 WARNING [main] org.apache.tomcat.util.digester.SetPropertiesRule.begin [SetPropertiesRule]{Server/Service/Engine/Host} Setting property 'debug' to '0' did not find a matching property. 03-Aug-2018 09:50:08.020 WARNING [main] org.apache.tomcat.util.digester.SetPropertiesRule.begin [SetPropertiesRule]{Server/Service/Engine/Host/Context} Setting property 'debug' to '0' did not find a matching property. 03-Aug-2018 09:50:08.051 WARNING [main] org.apache.tomcat.util.digester.SetPropertiesRule.begin [SetPropertiesRule]{Server/Service/Engine/Host/Context} Setting property 'debug' to '0' did not find a matching property. 03-Aug-2018 09:50:08.442 INFO [main] org.apache.coyote.AbstractProtocol.init Initializing ProtocolHandler ["http-nio-8090"] 03-Aug-2018 09:50:08.520 INFO [main] org.apache.tomcat.util.net.NioSelectorPool.getSharedSelector Using a shared selector for servlet write/read 03-Aug-2018 09:50:08.536 INFO [main] org.apache.catalina.startup.Catalina.load Initialization processed in 891 ms 03-Aug-2018 09:50:08.551 INFO [main] org.apache.catalina.core.StandardService.startInternal Starting service [Tomcat-Standalone] 03-Aug-2018 09:50:08.551 INFO [main] org.apache.catalina.core.StandardEngine.startInternal Starting Servlet Engine: Apache Tomcat/9.0.8 SLF4J: A number (1) of logging calls during the initialization phase have been intercepted and are SLF4J: now being replayed.

Hi Robert,

I noticed you have a support request open where some detailed steps are being discussed for your Data Center evaluation. I added myself as a watcher on the ticket so we can circle back to this thread to share the resolution with the Community.

Thanks,

Ann
