<!-- Answer --> HStore（Raft+RocksDB）分布式部署时，核心配置参数如下： 1. **raft.group_peers**：必填，指定所有 Raft 节点的 RPC 地址，格式如 `raft.group_peers=192.168.230.128:8091,192.168.230.129:8091,192.168.230.130:8091`，所有节点需保持一致。[参考](https://github.com/apache/incubator-hugegraph/blob/337dc86567834acd717a2240a79fef2815d4bb6f/hugegraph-server/hugegraph-api/src/main/java/org/apache/hugegraph/config/ServerOptions.java) 2. **raft.mode**：已废弃，建议不要再配置，实际是否启用 raft 由 `raft.group_peers` 是否存在决定。[参考](https://github.com/apache/incubator-hugegraph/blob/337dc86567834acd717a2240a79fef2815d4bb6f/hugegraph-server/hugegraph-dist/src/assembly/static/conf/graphs/hugegraph.properties) 3. **推荐 raft 相关参数**（全部写在 `graphs/hugegraph.properties`，单位见注释）： ``` # Raft 选举超时时间（毫秒，默认10000） raft.election_timeout=10000 # Raft RPC 连接超时（毫秒，默认5000） raft.rpc_connect_timeout=5000 # Raft RPC 超时（秒，默认60） raft.rpc_timeout=60 # 是否开启并行日志复制（默认true） raft.use_replicator_pipeline=true # 后端线程数（默认CPU核数） raft.backend_threads=8 # 读索引线程数（默认8） raft.read_index_threads=8 ``` 4. **rocksdb 相关建议**：合理设置 `rocksdb.write_buffer_size`、`rocksdb.max_write_buffer_number`、`rocksdb.block_cache_size`，多盘用 `rocksdb.data_disks`，定期 compact，JVM 内存建议调大。[参考](https://github.com/apache/incubator-hugegraph/issues/2762) 5. **端口分配**：每个节点的 REST、Gremlin、RPC 端口不能冲突，建议如 8081/8181/8091，8082/8182/8092，8083/8183/8093。[参考](https://github.com/apache/incubator-hugegraph/issues/2725) 6. **backend/serializer**：分布式部署推荐 `backend=hstore`，`serializer=binary`。[参考](https://github.com/apache/incubator-hugegraph/discussions/2710) 7. **初始化**：所有节点配置一致后，分别执行 `init-store.sh` 初始化，再启动服务。 注意：`raft.endpoint`、`raft.election_timeout_ms`、`raft.rpc_connect_timeout_ms`、`raft.rpc_timeout_ms` 等参数已废弃，需用上面新参数替换。[参考](https://github.com/apache/incubator-hugegraph/issues/2725) 如需详细样例或遇到具体报错可补充日志。 <!-- Dosu Comment Footer --> *To reply, just mention [@dosu](https://go.dosu.dev/dosubot).* --- <sup>How did I do?
