在CentOS下使用Docker搭建IotDB集群

以下为安装1.1版本的
一、准备3台机器，IP地址依次为IP1，IP2，IP3，找一个目录下建立文件夹如下：

./data/confignode
./logs/confignode
./data/datanode
./logs/datanode

二、在当前目录下建立docker-compose.yml文件，3台都要
1、第一台（为主节点的）

version: "3"
services:
  iotdb-confignode:
    image: apache/iotdb:1.1.0-confignode
    restart: always
    container_name: iotdb-confignode
    environment:
      - cn_internal_address=IP1
      - cn_target_config_node_list=IP1:10710
      - 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:
      - ./data/confignode:/iotdb/data
      - ./logs/confignode:/iotdb/logs
    network_mode: "host"

  iotdb-datanode:
    image: apache/iotdb:1.1.0-datanode
    restart: always
    container_name: iotdb-datanode
    environment:
      - dn_rpc_address=IP1
      - dn_internal_address=IP1
      - dn_target_config_node_list=IP1:10710
      - 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:
      - ./data/datanode:/iotdb/data/
      - ./logs/datanode:/iotdb/logs/
    network_mode: "host"

2、第二台机器

version: "3"
services:
  iotdb-confignode:
    image: apache/iotdb:1.1.0-confignode
    restart: always
    container_name: iotdb-confignode
    environment:
      - cn_internal_address=IP2
      - cn_target_config_node_list=IP2:10710
      - 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:
      - ./data/confignode:/iotdb/data
      - ./logs/confignode:/iotdb/logs
    network_mode: "host"

  iotdb-datanode:
    image: apache/iotdb:1.1.0-datanode
    restart: always
    container_name: iotdb-datanode
    environment:
      - dn_rpc_address=IP2
      - dn_internal_address=IP2
      - dn_target_config_node_list=IP1:10710
      - 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:
      - ./data/datanode:/iotdb/data/
      - ./logs/datanode:/iotdb/logs/
    network_mode: "host"

3、第三台机器

version: "3"
services:
  iotdb-confignode:
    image: apache/iotdb:1.1.0-confignode
    restart: always
    container_name: iotdb-confignode
    environment:
      - cn_internal_address=IP3
      - cn_target_config_node_list=IP3:10710
      - 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:
      - ./data/confignode:/iotdb/data
      - ./logs/confignode:/iotdb/logs
    network_mode: "host"

  iotdb-datanode:
    image: apache/iotdb:1.1.0-datanode
    restart: always
    container_name: iotdb-datanode
    environment:
      - dn_rpc_address=IP3
      - dn_internal_address=IP3
      - dn_target_config_node_list=IP1:10710
      - 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:
      - ./data/datanode:/iotdb/data/
      - ./logs/datanode:/iotdb/logs/
    network_mode: "host"

三、分别运行docker-compose.yml文件

docker-compose up -d

四、如果安装1.3版本的话
1、需要修改版本号 apache/iotdb:1.3.0-confignode和apache/iotdb:1.3.0-datanode
2、将原来environment中的dn_target_config_node_list替换为dn_seed_config_node=IP1:10710，cn_target_config_node_list替换为cn_seed_config_node 即可
