1.namesrv
1.1 拉取rocketMQ镜像
docker pull apache/rocketmq:4.9.4
1.2 创建nameserver数据存储目录
rocketMQ 分为nameserver和broker两部分,在启动时应该先启动nameserver,因此我们现在先创建nameserver的日志和数据存放目录。这个目录可由我们自己定义路径,这里我将其放到data路径
mkdir -p /app/rockedmq/logs /app/rockedmq/store
1.3 构建namesrv容器并启动
我们已经创建好了nameserver的日志和数据的存放路径,此时我们只需要挂在日志和数据路径,执行以下命令启动nameserver即可
docker run -d -p 9876:9876 --restart=always \
-v /data/docker-data/rockedmq/namesrv/logs:/home/rocketmq/logs \
-v /data/docker-data/rockedmq/namesrv/store:/home/rocketmq/store \
--name mqnamesrv \
--network rocketmq \
-e"JAVA_OPT_EXT=-server -Xms512m -Xmx512m -Xmn512m" \
apache/rocketmq:4.9.4 \
sh mqnamesrv
2.broker
2.1 创建broker数据存储路径
在操作这步之前,我们已经将nameserver启动成功,则接下来我们将要为broker创建数据挂载目录和配置文件,以确保broker能够成功启动。
mkdir -p /app/rocketmq/broker/logs /app/rocketmq/broker/store /app/rocketmq/broker/conf
说明:logs:是broker的日志目录,store:是broker的数据目录,conf是broker的配置信息目录
2.2 创建broker配置文件
我们刚刚已经创建了broker配置目录(/data/rocketmqbroker/conf),现在我们要在改配置目录下增加一个broker的配置文件,命名叫broker.conf
cd /app/rocketmq/broker/conf
vi broker.conf
注意:将一下信息复制到broker.conf文件中,请注意修改brokerIP1,改为您服务器的IP地址!注意修改namesrvAddr,改为您nameserver的IP地址!

所属集群名字
brokerClusterName=DefaultCluster
broker 名字,注意此处不同的配置文件填写的不一样,如果在 broker-a.properties 使用: broker-a,
在 broker-b.properties 使用: broker-b
brokerName=broker-a
0 表示 Master,> 0 表示 Slave
brokerId=0
nameServer地址,分号分割
namesrvAddr=192.168.18.200:9876
启动IP,如果 docker 报 com.alibaba.rocketmq.remoting.exception.RemotingConnectException: connect to <192.168.0.120:10909> failed
解决方式1 加上一句 producer.setVipChannelEnabled(false);,解决方式2 brokerIP1 设置宿主机IP,不要使用docker 内部IP
#producer.setVipChannelEnabled=false
brokerIP1=192.168.18.200
在发送消息时,自动创建服务器不存在的topic,默认创建的队列数
defaultTopicQueueNums=4
是否允许 Broker 自动创建 Topic,建议线下开启,线上关闭 !!!这里仔细看是 false,false,false
autoCreateTopicEnable=true
是否允许 Broker 自动创建订阅组,建议线下开启,线上关闭
autoCreateSubscriptionGroup=true
Broker 对外服务的监听端口
listenPort=10911
删除文件时间点,默认凌晨4点

-v /data/docker-data/rockedmq/broker/logs:/home/rocketmq/logs \
-v /data/docker-data/rockedmq/broker/store:/home/rocketmq/store \
-v /data/docker-data/rockedmq/broker/conf/broker.conf:/home/rocketmq/rocketmq-4.9.4/conf/broker.conf \
--name rmqbroker \
-e "NAMESRV_ADDR=namesrv:9876" \

3.RocketMQ-Console可视化界面
3.1 拉取rocketmq-console镜像
docker pull styletang/rocketmq-console-ng
3.2 构建RocketMQ-Console容器并启动

注意:将一下信息Drocketmq.namesrv.addr后面的IP地址改为您的nameserver IP地址!
