Example of 2 Node Cluster Configuration
This section contains examples of CloverDX Cluster nodes configuration. We assume that the user "clover" is running the JVM process and the license will be uploaded manually in the web GUI. In addition it is necessary to configure:
-
Sharing or replication of the file system directory which the property "sandboxes.home" is pointing to. E.g. on Unix-like systems it would be typically
/home/[username]/CloverDX/sandboxes. -
The connection to the same database from both nodes.
Basic 2-nodes Cluster Configuration
This example describes a simple Cluster: each node has a direct connection to a database.

This Cluster configuration is similar to the previous one, but only one node has direct access to a database. The node2 has to use node1 as a proxy.

If you use an external load balancer, the configuration of CloverDX Cluster will be same as in the first example.
Figure 214. Configuration of 2-nodes Cluster with load balancer
The cluster.http.url and cluster.jgroups.bind_address are URLs of particular Cluster nodes even if you use a load balancer.
