Docker搭建RocketMQ环境

docker-compose搭建rocketmq环境仅需要两个文件：

• broker.conf
• docker-compose-rocketmq.yaml

1、创建rocketmq工作目录，在目录下创建broker.conf文件，内容如下：

vim /data/rocketmq-docker/broker/conf/broker.conf

# 所属集群名称，如果节点较多可以配置多个
brokerClusterName = DefaultCluster
#broker名称，master和slave使用相同的名称，表明他们的主从关系
brokerName = broker-a
#0表示Master，大于0表示不同的slave
brokerId = 0
#表示几点做消息删除动作，默认是凌晨4点
deleteWhen = 04
#在磁盘上保留消息的时长，单位是小时
fileReservedTime = 48
#有三个值：SYNC_MASTER，ASYNC_MASTER，SLAVE；同步和异步表示Master和Slave之间同步数据的机制；
brokerRole = ASYNC_MASTER
#刷盘策略，取值为：ASYNC_FLUSH，SYNC_FLUSH表示同步刷盘和异步刷盘；SYNC_FLUSH消息写入磁盘后才返回成功状态，ASYNC_FLUSH不需要；
flushDiskType = ASYNC_FLUSH
# 设置broker节点所在服务器的ip地址
brokerIP1 = 192.168.146.138
# 磁盘使用达到95%之后,生产者再写入消息会报错 CODE: 14 DESC: service not available now, maybe disk full
diskMaxUsedSpaceRatio=95

• 注意把brokerIP1改成自己服务器的ip地址：

2、创建/opt/docker目录，并在目录下创建docker-compose-rocketmq.yaml文件，内容如下：

version: '3.5'
services:
 rmqnamesrv:
   image: rocketmqinc/rocketmq
   container_name: rmqnamesrv
   restart: always
   ports:
      - 9876:9876
   environment:
    #内存分配
    JAVA_OPT_EXT: "-server -Xms128m -Xmx128m"
   volumes:
     - /data/rocketmq-docker/namesrv/logs:/root/logs
     - /data/rocketmq-docker/namesrv/store:/root/store
   command: sh mqnamesrv
   networks:
     rocketmq:
       aliases:
         - rmqnamesrv
 rmqbroker:
   image: rocketmqinc/rocketmq
   container_name: rmqbroker
   restart: always
   depends_on:
     - rmqnamesrv
   ports:
     - 10909:10909
     - 10911:10911
   volumes:
     - /data/rocketmq-docker/broker/logs:/root/logs
     - /data/rocketmq-docker/broker/store:/root/store
     - /data/rocketmq-docker/broker/conf/broker.conf:/opt/rocketmq-4.4.0/conf/broker.conf
   command: sh mqbroker -c /opt/rocketmq-4.4.0/conf/broker.conf
   environment:
     NAMESRV_ADDR: "rmqnamesrv:9876"
     JAVA_OPT_EXT: "-server -Xms128m -Xmx128m -Xmn128m"
   networks:
     rocketmq:
       aliases:
         - rmqbroker
 rmqconsole:
   image: styletang/rocketmq-console-ng
   container_name: rocketmq-console
   restart: always
   ports:
     - 8080:8080
   depends_on:
     - rmqnamesrv
   volumes:
     - /etc/localtime:/etc/localtime:ro
     - /data/rocketmq-docker/console/logs:/root/logs
   environment:
     JAVA_OPTS: "-Drocketmq.namesrv.addr=rmqnamesrv:9876 -Dcom.rocketmq.sendMessageWithVIPChannel=false"
   networks:
     rocketmq:
       aliases:
         - rmqconsole
networks:
  rocketmq:
    name: rocketmq
    driver: bridge

3、启动镜像：

docker-compose -f docker-compose-rocketmq.yaml up -d

4、登录控制台：

ip:8080

访问成功即搭建成功。
