4. Add the remaining nodes to the cluster

  1. Copy the Crowd installation directory to the new node. 
  2. Create a home directory, like you did for the first node, and mount shared as its sub-directory.

  3. Edit crowd-init.properties, and enter the path to the home directory that you just created. 

    Where can I find crowd-init.properties?

    The crowd-init.properties file is in <installation-directory>\crowd-webapp\WEB-INF\classes\.

  4. Go to <installation-directory>/apache-tomcat/conf/Catalina/localhost, and delete the openidserver.xml file. This is needed because currently the CrowdID component doesn't support clustering, and it must be enabled only on the first node. The component will work as usual.
  5. Start Crowd. It will read the configuration from the shared directory, and start without any extra setup.
  6. Take a look around the new Crowd instance. Verify that user and group management, directory synchronization, and any custom integrations all work as expected.
  7. Again, verify that the node was added to the cluster. In Crowd, go to  > Clustering.

     

  8. If everything looks fine, you can configure your load balancer to start routing traffic to the new node. Once you do this, you can make a couple of changes in one Crowd instance to see if they're visible in other instances as well.
