Docker部署RocketMQ集群

方案:
1 个 Name Server
2 个 Master Broker
Docker 使用不同端口号部署


10.168.. rocketMq 端口号:
rmqnamesrv-a 9876
rmqbroker-a 10909,10911,10912
rmqbroker-b 11909,11911,11912
rmqconsole 9000
http://id:9000/

1、拉取镜像

docker pull rocketmqinc/rocketmq:4.3.0
docker pull styletang/rocketmq-console-ng

2、安装 docker-compose

curl -L https://get.daocloud.io/docker/compose/releases/download/1.24.1/docker-compose-`uname -s`-`uname -m` > /usr/local/bin/docker-compose
sudo chmod +x /usr/local/bin/docker-compose
docker-compose --version

3、创建数据文件夹文件夹

mkdir docker_rocketmq_data
cd docker_rocketmq_data

mkdir -p ./logs/nameserver-a
mkdir -p ./store/nameserver-a

mkdir -p ./logs/broker-a
mkdir -p ./store/broker-a

mkdir -p ./logs/broker-b
mkdir -p ./store/broker-b

4、broker-a.conf

brokerClusterName = rocketmq-cluster
brokerName = broker-a
brokerId = 0
brokerIP1 = 10.168.2.14
deleteWhen = 04
fileReservedTime = 48
brokerRole = ASYNC_MASTER
flushDiskType = ASYNC_FLUSH
namesrvAddr = 10.168.2.14:9876
autoCreateTopicEnable=true
listenPort = 10911
brokerRole=ASYNC_MASTER
flushDiskType=ASYNC_FLUSH

5、broker-b.conf

brokerClusterName = rocketmq-cluster
brokerName = broker-b
brokerId = 0
brokerIP1 = 10.168.2.14
deleteWhen = 04
fileReservedTime = 48
brokerRole = ASYNC_MASTER
flushDiskType = ASYNC_FLUSH
namesrvAddr=10.168.2.14:9876
autoCreateTopicEnable=true
listenPort = 11911
brokerRole=ASYNC_MASTER
flushDiskType=ASYNC_FLUSH

6、目录结构

7、docker-compose.yml

注意修改 volumes 路径

version: '3.5'
services:
  rmqnamesrv-a:
    image: rocketmqinc/rocketmq:4.3.0
    container_name: rmqnamesrv-a
    ports:

    volumes:
      - /home/userName/docker_rocketmq_data/logs/nameserver-a:/opt/logs

    ports:
      - 10909:10909
      - 10911:10911
      - 10912:10912
    volumes:
      - /home/userName/docker_rocketmq_data/logs/broker-a:/opt/logs

    environment:
        TZ: Asia/Shanghai
        NAMESRV_ADDR: "rmqnamesrv-a:9876"
        JAVA_OPTS: " -Duser.home=/opt"
        JAVA_OPT_EXT: "-server -Xms256m -Xmx256m -Xmn256m"
    command: sh mqbroker -c /opt/rocketmq-4.3.0/conf/broker.conf autoCreateTopicEnable=true &
    links:
      - rmqnamesrv-a:rmqnamesrv-a
    networks:
      rmq:
        aliases:
          - rmqbroker-a

  rmqbroker-b:
    image: rocketmqinc/rocketmq:4.3.0
    container_name: rmqbroker-b
    ports:
      - 11909:11909

      - /home/userName/docker_rocketmq_data/store/broker-b:/opt/store
      - /home/userName/docker_rocketmq_data/broker-b.conf:/opt/rocketmq-4.3.0/conf/broker.conf 
    environment:
        TZ: Asia/Shanghai
        NAMESRV_ADDR: "rmqnamesrv-b:9876"
        JAVA_OPTS: " -Duser.home=/opt"
        JAVA_OPT_EXT: "-server -Xms256m -Xmx256m -Xmn256m"
    command: sh mqbroker -c /opt/rocketmq-4.3.0/conf/broker.conf autoCreateTopicEnable=true &
    links:
      - rmqnamesrv-a:rmqnamesrv-a
    networks:
      rmq:
        aliases:
          - rmqbroker-b

  rmqconsole:
    image: styletang/rocketmq-console-ng
    container_name: rmqconsole
    ports:
      - 9000:8080
    environment:
        JAVA_OPTS: -Drocketmq.namesrv.addr=rmqnamesrv-a:9876 -Dcom.rocketmq.sendMessageWithVIPChannel=false
    networks:
      rmq:
        aliases:
          - rmqconsole
networks:
  rmq:
    name: rmq
    driver: bridge

8、启动服务

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

9、端口号

10.168.2.14 rocketMq 端口号:

rmqnamesrv-a 9876

rmqbroker-a 10909,10911,10912

rmqbroker-b 11909,11911,11912

rmqconsole 9000

http://ip:9000/

10、配置文件说明

brokerClusterName = rocketmq-cluster
brokerName = broker-a
brokerId = 0
#这个很有讲究 如果是正式环境 这里一定要填写内网地址(安全)
#如果是用于测试或者本地这里建议要填外网地址,因为你的本地代码是无法连接到阿里云内网,只能连接外网。
brokerIP1 = xxxxx
deleteWhen = 04
fileReservedTime = 48
brokerRole = ASYNC_MASTER
flushDiskType = ASYNC_FLUSH
# 内网的(阿里云有内网IP和外网IP)
namesrvAddr=172.18.0.5:9876;172.18.0.5:9877
autoCreateTopicEnable=true
#Broker 对外服务的监听端口,
listenPort = 10911
#Broker角色
#- ASYNC_MASTER 异步复制Master
#- SYNC_MASTER 同步双写Master
#- SLAVE
brokerRole=ASYNC_MASTER
#刷盘方式
#- ASYNC_FLUSH 异步刷盘
#- SYNC_FLUSH 同步刷盘
flushDiskType=ASYNC_FLUSH

11、测试代码
