<!-- Answer --> HugeGraph 分布式部署 RocksDB（Raft 模式）大致流程如下： 1. 环境准备：每台机器安装 JDK 11+，建议 16GB 以上内存，SSD 更佳。下载 HugeGraph 1.5.0 二进制包或官方 Docker 镜像（推荐用 release tag）。 2. 配置文件（每台节点 graphs/hugegraph.properties 必须一致）： ```properties backend=rocksdb serializer=binary store=hugegraph rocksdb.data_path=./data rocksdb.wal_path=./wal raft.group_peers=192.168.230.128:8091,192.168.230.129:8091,192.168.230.130:8091 # 推荐 raft 相关参数 raft.election_timeout=10000 raft.rpc_connect_timeout=5000 raft.rpc_timeout=60 # RocksDB 性能参数（单位为字节，不能写 128MB，需写 134217728） rocksdb.write_buffer_size=134217728 rocksdb.max_write_buffer_number=6 rocksdb.block_cache_size=8589934592 ``` 注意 raft.mode、raft.endpoint、raft.election_timeout_ms 等参数已废弃，不能再用。 3. rest-server.properties 只需配置 REST/RPC 端口，graphs 路径等，不要写 raft.group_peers。 4. 启动顺序：每台节点都执行一次 `bin/init-store.sh` 初始化（确保 data 目录无锁文件、无其他进程占用），然后启动服务 `bin/start-hugegraph.sh`。Docker 环境可用 `JAVA_OPTS` 环境变量设置 JVM 堆内存（如 `-Xmx32g -Xms32g`），docker-compose 需挂载各自配置文件，环境变量前缀用 hugegraph.。 5. 端口分配：每台节点 REST、Gremlin、RPC 端口不能冲突，比如 8081/8181/8091，8082/8182/8092，8083/8183/8093。 6. 常见问题：rocksdb.write_buffer_size、rocksdb.block_cache_size 等参数必须用字节数（如 134217728），不能写 128MB，否则报类型错误。遇到 lock 报错需确保无进程占用，必要时手动删除 lock 文件（确保无服务运行）[参考](https://github.com/apache/incubator-hugegraph/issues/2762)。 7. 集群健康：所有节点配置完全一致，raft.group_peers 必须包含所有节点，节点间网络互通，data/wal 路径可写。 详细可参考官方配置模板和 [分布式部署经验](https://github.com/apache/incubator-hugegraph/issues/2725)。如遇具体报错可贴日志进一步定位。 <!-- Dosu Comment Footer --> *To reply, just mention [@dosu](https://go.dosu.dev/dosubot).* --- <sup>How did I do?
