通过docker部署rocketmq双主双从集群

1. 环境准备

阿某云：centos 7，47.77.*.*（172.21.*.*），在安全组策略开启8000-9000之间的端口访问权限。

2. 创建目录

mkdir /opt/rocketmq/logs/nameserver-1
mkdir /opt/rocketmq/logs/nameserver-2
mkdir /opt/rocketmq/logs/broker-master-1
mkdir /opt/rocketmq/logs/broker-master-2
mkdir /opt/rocketmq/logs/broker-slave-1
mkdir /opt/rocketmq/logs/broker-slave-2
mkdir /opt/rocketmq/store/nameserver-1
mkdir /opt/rocketmq/store/nameserver-2
mkdir /opt/rocketmq/store/broker-master-1
mkdir /opt/rocketmq/store/broker-master-2
mkdir /opt/rocketmq/store/broker-slave-1
mkdir /opt/rocketmq/store/broker-slave-2
mkdir /root/rocketmq/broker-master-1/conf
mkdir /root/rocketmq/broker-master-2/conf
mkdir /root/rocketmq/broker-slave-1/conf
mkdir /root/rocketmq/broker-slave-2/conf

3. 获取镜像

nameserver

docker pull foxiswho/rocketmq:server-4.3.2

broker

docker pull foxiswho/rocketmq:broker-4.3.2

rocketmq-console

docker pull styletang/rocketmq-console-ng

4. 创建容器

nameserver-1

docker create -p 8201:9876 --name rmq-nameserver-1 -e "JAVA_OPT_EXT=-server -Xms128m -Xmx128m -Xmn128m" -e "JAVA_OPTS=-Duser.home=/opt" -v /opt/rocketmq/logs/nameserver-1:/opt/logs -v /opt/rocketmq/store/nameserver-1:/opt/store foxiswho/rocketmq:server-4.3.2

nameserver-2

docker create -p 8202:9876 --name rmq-nameserver-2 -e "JAVA_OPT_EXT=-server -Xms128m -Xmx128m -Xmn128m" -e "JAVA_OPTS=-Duser.home=/opt" -v /opt/rocketmq/logs/nameserver-2:/opt/logs -v /opt/rocketmq/store/nameserver-2:/opt/store foxiswho/rocketmq:server-4.3.2

master-1

docker create --net host --name rmq-master-1 -e "JAVA_OPTS=-Duser.home=/opt" -e "JAVA_OPT_EXT=-server -Xms128m -Xmx128m -Xmn128m" -v /root/rocketmq/broker-master-1/conf/broker.conf:/etc/rocketmq/broker.conf -v /opt/rocketmq/logs/broker-master-1:/opt/logs -v /opt/rocketmq/store/broker-master-1:/opt/store foxiswho/rocketmq:broker-4.3.2

master-2

docker create --net host --name rmq-master-2 -e "JAVA_OPTS=-Duser.home=/opt" -e "JAVA_OPT_EXT=-server -Xms128m -Xmx128m -Xmn128m" -v /root/rocketmq/broker-master-2/conf/broker.conf:/etc/rocketmq/broker.conf -v /opt/rocketmq/logs/broker-master-2:/opt/logs -v /opt/rocketmq/store/broker-master-2:/opt/store foxiswho/rocketmq:broker-4.3.2

slave-1

docker create --net host --name rmq-slave-1 -e "JAVA_OPTS=-Duser.home=/opt" -e "JAVA_OPT_EXT=-server -Xms128m -Xmx128m -Xmn128m" -v /root/rocketmq/broker-slave-1/conf/broker.conf:/etc/rocketmq/broker.conf -v /opt/rocketmq/logs/broker-slave-1:/opt/logs -v /opt/rocketmq/store/broker-slave-1:/opt/store foxiswho/rocketmq:broker-4.3.2

slave-2

docker create --net host --name rmq-slave-2 -e "JAVA_OPTS=-Duser.home=/opt" -e "JAVA_OPT_EXT=-server -Xms128m -Xmx128m -Xmn128m" -v /root/rocketmq/broker-slave-2/conf/broker.conf:/etc/rocketmq/broker.conf -v /opt/rocketmq/logs/broker-slave-2:/opt/logs -v /opt/rocketmq/store/broker-slave-2:/opt/store foxiswho/rocketmq:broker-4.3.2

5. 创建配置文件

/root/rocketmq/broker-master-1/conf/broker.conf

namesrvAddr=172.21.*.*:8201;172.21.*.*:8202
brokerClusterName=myCluster
brokerName=broker01
brokerId=0
deleteWhen=04
fileReservedTime=48
brokerRole=SYNC_MASTER
flushDiskType=ASYNC_FLUSH
brokerIP1=47.77.*.*
brokerIp2=47.77.*.*
listenPort=8111

/root/rocketmq/broker-master-2/conf/broker.conf

namesrvAddr=172.21.*.*:8201;172.21.*.*:8202
brokerClusterName=myCluster
brokerName=broker02
brokerId=0
deleteWhen=04
fileReservedTime=48
brokerRole=SYNC_MASTER
flushDiskType=ASYNC_FLUSH
brokerIP1=47.77.*.*
brokerIp2=47.77.*.*
listenPort=8211

/root/rocketmq/broker-slave-1/conf/broker.conf

namesrvAddr=172.21.*.*:8201;172.21.*.*:8202
brokerClusterName=myCluster
brokerName=broker01
brokerId=1
deleteWhen=04
fileReservedTime=48
brokerRole=SLAVE
flushDiskType=ASYNC_FLUSH
brokerIP1=47.77.*.*
listenPort=8115

/root/rocketmq/broker-slave-2/conf/broker.conf

namesrvAddr=172.21.*.*:8201;172.21.*.*:8202
brokerClusterName=myCluster
brokerName=broker02
brokerId=1
deleteWhen=04
fileReservedTime=48
brokerRole=SLAVE
flushDiskType=ASYNC_FLUSH
brokerIP1=47.77.*.*
listenPort=8215

6. 启动容器

先启动nameserver

docker start rmq-nameserver-1 rmq-nameserver-2

启动broker

docker start rmq-master-1 rmq-master-2 rmq-slave-1 rmq-slave-2

启动rocketmq-console

docker run -dit --name rocketmq-console-ng -e "JAVA_OPTS=-Drocketmq.namesrv.addr=172.21.*.*:8201;172.21.*.*:8202 -Dcom.rocketmq.sendMessageWithVIPChannel=false" -p 8203:8080 styletang/rocketmq-console-ng

启动完成后查看容器状态

7. 端口说明

broker会使用3个端口：

listenPort：默认10911，监听端口，客户端通过这个端口连接broker，上面分别改成8111和8211

haListenPort：ha端口，用于主从同步，在listenPort基础上加1，即10912

vipChannelPort：vip通道端口，在listenPort基础上减2，即10909

如果启动时出现端口冲突，但是配置文件里面是不同的listenPort，很有可能就是后面2个端口冲突了。

8. 通过rocketmq-console访问集群
