以本地环境为例,演示 IoTDB 集群的启动、扩容与缩容。
注意:本文档为使用本地不同端口,进行伪分布式环境部署的教程,仅用于练习。在真实环境部署时,一般不需要修改节点端口,仅需配置节点 IPV4 地址或域名即可。
解压 apache-iotdb-1.0.0-all-bin.zip 至 cluster0 目录。
在 Linux 环境中,部署 1 个 ConfigNode 和 1 个 DataNode(1C1D)集群版,默认 1 副本:
./cluster0/sbin/start-confignode.sh ./cluster0/sbin/start-datanode.sh
./cluster0/sbin/start-cli.sh

解压 apache-iotdb-1.0.0-all-bin.zip 至 cluster1 目录和 cluster2 目录
对于 cluster1 目录:
| 配置项 | 值 |
|---|---|
| cn_internal_address | 127.0.0.1 |
| cn_internal_port | 10711 |
| cn_consensus_port | 10721 |
| cn_target_config_node_list | 127.0.0.1:10710 |
| 配置项 | 值 |
|---|---|
| dn_rpc_address | 127.0.0.1 |
| dn_rpc_port | 6668 |
| dn_internal_address | 127.0.0.1 |
| dn_internal_port | 10731 |
| dn_mpp_data_exchange_port | 10741 |
| dn_schema_region_consensus_port | 10751 |
| dn_data_region_consensus_port | 10761 |
| dn_target_config_node_list | 127.0.0.1:10710 |
对于 cluster2 目录:
| 配置项 | 值 |
|---|---|
| cn_internal_address | 127.0.0.1 |
| cn_internal_port | 10712 |
| cn_consensus_port | 10722 |
| cn_target_config_node_list | 127.0.0.1:10710 |
| 配置项 | 值 |
|---|---|
| dn_rpc_address | 127.0.0.1 |
| dn_rpc_port | 6669 |
| dn_internal_address | 127.0.0.1 |
| dn_internal_port | 10732 |
| dn_mpp_data_exchange_port | 10742 |

| dn_data_region_consensus_port | 10762 |
| dn_target_config_node_list | 127.0.0.1:10710 |
将集群扩容至 3 个 ConfigNode 和 3 个 DataNode(3C3D)集群版, 指令执行顺序为先启动 ConfigNode,再启动 DataNode:
./cluster1/sbin/start-confignode.sh ./cluster2/sbin/start-confignode.sh ./cluster1/sbin/start-datanode.sh ./cluster2/sbin/start-datanode.sh
在 Cli 执行 show cluster details,结果如下:
