docker部署
Apache IoTDB 的 Docker 镜像已经上传至 https://hub.docker.com/r/apache/iotdbopen in new window。
Apache IoTDB 的配置项以环境变量形式添加到容器内。
docker镜像安装(单机版)
# 获取镜像
docker pull apache/iotdb:1.1.0-standalone
# 创建 docker bridge 网络
docker network create --driver=bridge --subnet=172.18.0.0/16 --gateway=172.18.0.1 iotdb
# 创建 docker 容器
# 注意:必须固定IP部署。IP改变会导致 confignode 启动失败。
docker run -d --name iotdb-service \

# 尝试使用命令行执行SQL
docker exec -ti iotdb-service /iotdb/sbin/start-cli.sh -h iotdb-service
外部连接:
# <主机IP/hostname> 是物理机的真实IP或域名。如果在同一台物理机,可以是127.0.0.1。

docker镜像安装(集群版)
目前只支持 host 网络和 overlay 网络,不支持 bridge 网络。overlay 网络参照1C2Dopen in new window的写法,host 网络如下。
假如有三台物理机,它们的hostname分别是iotdb-1、iotdb-2、iotdb-3。依次启动。
以 iotdb-2 节点的docker-compose文件为例:
version: "3"
services:
iotdb-confignode:
image: apache/iotdb:1.1.0-confignode
container_name: iotdb-confignode
environment:
- cn_internal_address=iotdb-2
- cn_target_config_node_list=iotdb-1:10710
- schema_replication_factor=3
- cn_internal_port=10710
- cn_consensus_port=10720
- schema_region_consensus_protocol_class=org.apache.iotdb.consensus.ratis.RatisConsensus
- config_node_consensus_protocol_class=org.apache.iotdb.consensus.ratis.RatisConsensus
- data_replication_factor=3
- data_region_consensus_protocol_class=org.apache.iotdb.consensus.iot.IoTConsensus
volumes:
- /etc/hosts:/etc/hosts:ro
- ./data/confignode:/iotdb/data
- ./logs/confignode:/iotdb/logs
network_mode: "host"
iotdb-datanode:
image: apache/iotdb:1.1.0-datanode
container_name: iotdb-datanode
environment:
- dn_rpc_address=iotdb-2
- dn_internal_address=iotdb-2
- dn_target_config_node_list=iotdb-1:10710
- data_replication_factor=3
- dn_rpc_port=6667
- dn_mpp_data_exchange_port=10740
- dn_schema_region_consensus_port=10750
- dn_data_region_consensus_port=10760
- data_region_consensus_protocol_class=org.apache.iotdb.consensus.iot.IoTConsensus
- schema_replication_factor=3
- schema_region_consensus_protocol_class=org.apache.iotdb.consensus.ratis.RatisConsensus
- config_node_consensus_protocol_class=org.apache.iotdb.consensus.ratis.RatisConsensus
volumes:
- /etc/hosts:/etc/hosts:ro
- ./data/datanode:/iotdb/data/
- ./logs/datanode:/iotdb/logs/
network_mode: "host"
注意:
dn_target_config_node_list
所有节点配置一样,需要配置第一个启动的节点,这里为iotdb-1
。- 上面docker-compose文件中,
iotdb-2
需要替换为每个节点的 hostname、域名或者IP地址。 - 需要映射
/etc/hosts
,文件内配置了 iotdb-1、iotdb-2、iotdb-3 与IP的映射。或者可以在 docker-compose 文件中增加extra_hosts
配置。 - 首次启动时,必须首先启动
iotdb-1
。 - 如果部署失败要重新部署集群,必须将所有节点上的IoTDB服务停止并删除,然后清除
data
和logs
文件夹后,再启动。
