HugeGraph Multi‐Node Deployment Configuration

For reference only. Taking a three-node deployment with RocksDB backend under Raft mode as an example, validation was performed under this commit.

After referring to the HugeGraph-Server Quick Start and building HugeGraph from the source code, you can find the folder hugegraph-server/apache-hugegraph-incubating-* in the project path. Copy this folder into three replicas A, B, C, and configure them sequentially (keep the default values for unspecified configuration items).

TL;DR

• Set raft.mode to true in hugegraph.properties.
• Set the REST ports to 8081, 8082, 8083 sequentially.
• Set the Gremlin ports to 8181, 8182, 8183 sequentially.
• Ensure no conflicts for Arthas ports on each node.
• Set the RPC ports to 8091, 8092, 8093 sequentially; these ports are essential for communication between Raft nodes.
• Download the corresponding configuration files at this location.
