Docker部署RocketMq

环境

docker 19+

# 前置环境推荐
	Docker 19+
	
# 下载内容
docker pull apache/rocketmq:4.7.1

# 创建namesrv数据存储路径
mkdir -p  /home/jamel/docker/software/rocketmq/data/namesrv/logs
mkdir -p  /home/jamel/docker/software/rocketmq/data/namesrv/store

# 创建broker存储路径
mkdir -p /home/jamel/docker/software/rocketmq/broker/broker-a

第一步：启动 namesrv

docker run -d \
	--restart=always \
	--name rocketmq-namesrv-4.7.1 \
	-p 9876:9876 \
	-m 1024m \
	-v /home/jamel/docker/software/rocketmq/data/namesrv/logs:/root/logs \
	-v /home/jamel/docker/software/rocketmq/data/namesrv/store:/root/store \
	apache/rocketmq:4.7.1 sh mqnamesrv

第二步：生成broker-a服务的配置

# 通过docker ps 找到刚启动成功的rocketmq-namesrv-4.7.1 容器id

# 复制容器内mq配置生成 broker配置
docker cp rocketmq:4.7.1:/home/rocketmq/rocketmq-4.7.1/conf /home/jamel/docker/software/rocketmq/broker/broker-a/

第三步：调整broker-a的配置文件

vim /home/jamel/docker/software/rocketmq/broker/broker-a/conf/broker.conf (下面只需要调整 brokerIP1 & namesrvAddr)

# 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 = SYNC_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 = SYNC_FLUSH
# 设置broker节点所在服务器的ip地址（**这个非常重要,主从模式下，从节点会根据主节点的brokerIP2来同步数据，如果不配置，主从无法同步，brokerIP1设置为自己外网能访问的ip，服务器双网卡情况下必须配置，比如阿里云这种，主节点需要配置ip1和ip2，从节点只需要配置ip1即可）
brokerIP1 = 192.168.110.x
#nameServer地址，分号分割
namesrvAddr=192.168.110.x:9876
#Broker 对外服务的监听端口,
listenPort = 10911
#是否允许Broker自动创建Topic
autoCreateTopicEnable = true
#是否允许 Broker 自动创建订阅组
autoCreateSubscriptionGroup = true
#linux开启epoll
useEpollNativeSelector = true

#数据存放的根目录
#storePathRootDir = /root/store/path
#commit log保存目录
#storePathCommitLog = /root/store/path/commitlog
#消费队列存储路径存储路径
#storePathConsumerQueue = /root/store/path/consumequeue

slaveReadEnable = true

第四步：启动broker-a

docker run -d \
--name rocketmq-broker-a \
--restart=always \
-p 10909:10909  \
-p 10911:10911  \
-m 2048m \
-v /home/jamel/docker/software/rocketmq/broker/broker-a/logs:/root/logs  \
-v /home/jamel/docker/software/rocketmq/broker/broker-a/store:/root/store  \
-v /home/jamel/docker/software/rocketmq/broker/broker-a/conf:/home/rocketmq/rocketmq-4.7.1/conf \
-e "JAVA_OPT_EXT=-server -Xms1g -Xmx1g -Xmn512m" apache/rocketmq:4.7.1 sh mqbroker -c /home/rocketmq/rocketmq-4.7.1/conf/broker.conf

启动

第一步: 启动broker-a，启动后确认启动日志是否出现成功信息 docker logs --tail=100 -f rocketmq-broker-a

docker run -d \
--name rocketmq-broker-a \
--restart=always \
-p 10909:10909  \
-p 10911:10911  \
-m 2048m \
-v /home/jamel/docker/software/rocketmq/broker/broker-a/logs:/root/logs  \
-v /home/jamel/docker/software/rocketmq/broker/broker-a/store:/root/store  \
-v /home/jamel/docker/software/rocketmq/broker/broker-a/conf:/home/rocketmq/rocketmq-4.7.1/conf \
-e "JAVA_OPT_EXT=-server -Xms1g -Xmx1g -Xmn512m" apache/rocketmq:4.7.1 sh mqbroker -c /home/rocketmq/rocketmq-4.7.1/conf/broker.conf

第二步：启动rocketmq控制台，启动后确认启动日志是否出现成功信息 docker logs --tail=100 -f rmqadmin

docker run -d \
--restart=always \
--name rmqadmin \
-m 2048m \
-e "JAVA_OPTS=-Drocketmq.namesrv.addr=192.168.110.x:9876 -Dcom.rocketmq.sendMessageWithVIPChannel=false" \
-p 5001:8080 \

确认部署结果:http://192.168.110.x:5001/

使用

访问管理页面

问题

1. 访问控制台提示 “Caused by: org.apache.rocketmq.remoting.exception.RemotingConnectException: connect to null failed”

1.如果是阿里云环境下部署的，请去控制台开放 9876 和 10911 端口

2.物理服务器报错可以尝试开放端口：9876、10911
	systemctl start firewalld
	firewall-cmd --zone=public --add-port=9876/tcp --permanent
	firewall-cmd --zone=public --add-port=10911/tcp --permanent
	firewall-cmd --reload
