基於Docker部署RocketMQ兩主兩從異步集羣搭建

文末有完整的源碼下載，大家可以參考着實踐一下。

1、創建Dockerfile-centos文件

構建鏡像 指定ROCKETMQ_VERSION

docker build --no-cache -f Dockerfile-centos -t rocketmqinc/rocketmq:${ROCKETMQ_VERSION} --build-arg version=${ROCKETMQ_VERSION} .

2、兩主兩從異步清除刷盤,broker配置

broker-a.conf

brokerClusterName=DefaultCluster
brokerName=broker-a
brokerId=0
deleteWhen=04
fileReservedTime=48
brokerRole=ASYNC_MASTER
flushDiskType=ASYNC_FLUSH

# Host node's dns-name or ip
brokerIP1=172.16.218.144

# Optional config different value rather than default ports.
# Caution: changing default ports need to update port mapping setting (-p) in start-broker.sh
listenPort=10911
#haListenPort=10912

broker-a-s.conf

brokerClusterName=DefaultCluster
brokerName=broker-a
brokerId=1
deleteWhen=04
fileReservedTime=48
brokerRole=SLAVE
flushDiskType=ASYNC_FLUSH


#Slave host dns-name/ip
brokerIP1=172.16.218.144
#with Master's BroperIP1
brokerIP2=172.16.218.144
#同一臺機器部署多個broker，端口號要不同，且端口號之間要相距大些
listenPort=12911

broker-b.conf

brokerClusterName=DefaultCluster
brokerName=broker-b
brokerId=0
deleteWhen=04
fileReservedTime=48
brokerRole=ASYNC_MASTER
flushDiskType=ASYNC_FLUSH

# Host node's dns-name or ip
brokerIP1=172.16.218.144

# Optional config different value rather than default ports.
# Caution: changing default ports need to update port mapping setting (-p) in start-broker.sh
#同一臺機器部署多個broker，端口號要不同，且端口號之間要相距大些
listenPort=11911
#haListenPort=10912

broker-b-s.conf

brokerClusterName=DefaultCluster
brokerName=broker-b
brokerId=1
deleteWhen=04
fileReservedTime=48
brokerRole=SLAVE
flushDiskType=ASYNC_FLUSH


#Slave host dns-name/ip
brokerIP1=172.16.218.144
#with Master's BroperIP1
brokerIP2=172.16.218.144
#同一臺機器部署多個broker，端口號要不同，且端口號之間要相距大些
listenPort=13911

3、創建docker-Compose.yml

version: '3'
services:
  namesrv:
    image: rocketmqinc/rocketmq:4.6.0
    container_name: rmqnamesrv
    ports:
      - 9876:9876

    container_name: rmqbroker-a-s
    links:

  broker-b-s:
    image: rocketmqinc/rocketmq:4.6.0
    container_name: rmqbroker-b-s
    links:
      - namesrv
    ports:
      - 13909:10909
      - 13911:13911
      - 13912:10912
    environment:
      - NAMESRV_ADDR=namesrv:9876
    volumes:
      - ./data4/broker/logs:/home/rocketmq/logs
      - ./data4/broker/store:/home/rocketmq/store
      - ./data4/broker/conf/broker-b-s.conf:/home/rocketmq/rocketmq-4.6.0/conf/broker-b-s.conf
    command: sh mqbroker -c ../conf/broker-b-s.conf
    networks:
      rocketmq:
        ipv4_address: 172.23.0.6
        aliases:

    driver: bridge
    ipam:
      driver: default
      config:

4、運行nameServer、broker和rocketmq-console-ng

docker-compose -f ./docker-compose/docker-compose.yml up -d
