| === Cluster setup |
| |
| Apache Karaf relies on Apache Karaf Cellar, which in turn uses Hazelcast to discover and configure its cluster. |
| |
| You can control most of the important clustering settings through the centralized configuration file at |
| |
| etc/unomi.custom.system.properties |
| |
| And notably using the following properties: |
| |
| org.apache.unomi.hazelcast.group.name=${env:UNOMI_HAZELCAST_GROUP_NAME:-cellar} |
| org.apache.unomi.hazelcast.group.password=${env:UNOMI_HAZELCAST_GROUP_PASSWORD:-pass} |
| # This list can be comma separated and use ranges such as 192.168.1.0-7,192.168.1.21 |
| org.apache.unomi.hazelcast.tcp-ip.members=${env:UNOMI_HAZELCAST_TCPIP_MEMBERS:-127.0.0.1} |
| org.apache.unomi.hazelcast.tcp-ip.interface=${env:UNOMI_HAZELCAST_TCPIP_INTERFACE:-127.0.0.1} |
| org.apache.unomi.hazelcast.network.port=${env:UNOMI_HAZELCAST_NETWORK_PORT:-5701} |
| |
| If you need more fine-grained control over the Hazelcast configuration you could also edit the following file: |
| |
| [source] |
| ---- |
| etc/hazelcast.xml |
| ---- |
| |
| Note that it would be best to keep all configuration in the centralized custom configuration, for example by adding |
| placeholders in the hazelcast.xml file if need be and adding the properties to the centralized configuration file. |
