docker单机安装rocketmq双主双从

1. 环境准备

阿某云：centos 7，47.*.*.*（172.*.*.*），在安全组策略开启8000-9000之间的端口访问权限。
注意一定要开放安全组端口，否则无法访问console控制台

2. 创建目录

mkdir -p /usr/local/rocketmq/logs/nameserver-1
mkdir -p /usr/local/rocketmq/logs/nameserver-2
mkdir -p /usr/local/rocketmq/logs/broker-master-1
mkdir -p /usr/local/rocketmq/logs/broker-master-2
mkdir -p /usr/local/rocketmq/logs/broker-slave-1
mkdir -p /usr/local/rocketmq/logs/broker-slave-2

mkdir -p /usr/local/rocketmq/store/nameserver-1
mkdir -p /usr/local/rocketmq/store/nameserver-2
mkdir -p /usr/local/rocketmq/store/broker-master-1
mkdir -p /usr/local/rocketmq/store/broker-master-2
mkdir -p /usr/local/rocketmq/store/broker-slave-1
mkdir -p /usr/local/rocketmq/store/broker-slave-2

mkdir -p /usr/local/rocketmq/conf/broker-master-1
mkdir -p /usr/local/rocketmq/conf/broker-master-2
mkdir -p /usr/local/rocketmq/conf/broker-slave-1
mkdir -p /usr/local/rocketmq/conf/broker-slave-2

3. 获取镜像

nameserver镜像

docker pull foxiswho/rocketmq:server-4.3.2

broker镜像
docker pull foxiswho/rocketmq:broker-4.3.2

rocketmq-console镜像
docker pull styletang/rocketmq-console-ng

4. 创建容器

nameserver容器

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


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

broker容器

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


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

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

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

5. 创建配置文件

注意：

1.brokerId  从节点错误，主节点是0，从节点是1

2.主从复制模式：brokerRole，总共3种模式，如果是从节点 该值是 SLAVE

3.刷盘机制：flushDiskType=ASYNC_FLUSH，异步刷盘 同步刷盘

如何选择：主从复制选择同步复制保证消息不丢失，异步刷盘保证效率

 

cat > /usr/local/rocketmq/conf/broker-master-1/broker.conf << EOF
listenPort=8111
brokerIP1=47.103.*.*
brokerClusterName=DefaultCluster
brokerName=broker-m1
brokerRole=SYNC_MASTER
brokerId=0
deleteWhen=04
fileReservedTime=48
flushDiskType=ASYNC_FLUSH
namesrvAddr=47.103.*.*:8201;47.103.*.*:8202
EOF
 
cat > /usr/local/rocketmq/conf/broker-master-2/broker.conf << EOF
listenPort=8211
brokerIP1=47.103.*.*
brokerClusterName=DefaultCluster
brokerName=broker-m2
brokerRole=SYNC_MASTER
brokerId=0
deleteWhen=04
fileReservedTime=48
flushDiskType=ASYNC_FLUSH
namesrvAddr=47.103.*.*:8201;47.103.*.*:8202
EOF
 
 
cat > /usr/local/rocketmq/conf/broker-slave-1/broker.conf << EOF
listenPort=8115
brokerIP1=47.103.*.*
brokerClusterName=DefaultCluster
brokerName=broker-s1
brokerRole=SLAVE
brokerId=1
deleteWhen=04
fileReservedTime=48
flushDiskType=ASYNC_FLUSH
namesrvAddr=47.103.*.*:8201;47.103.*.*:8202
EOF
 
cat > /usr/local/rocketmq/conf/broker-slave-2/broker.conf << EOF
listenPort=8215
brokerIP1=47.103.*.*
brokerClusterName=DefaultCluster
brokerName=broker-s2
brokerRole=SLAVE
brokerId=1
deleteWhen=04
fileReservedTime=48
flushDiskType=ASYNC_FLUSH
namesrvAddr=47.103.*.*:8201;47.103.*.*:8202
EOF

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=47.103.*.*:8201;47.103.*.*:8202 -Dcom.rocketmq.sendMessageWithVIPChannel=false" -p 8203:8080 styletang/rocketmq-console-ng

7.访问

http://47.103.*.*:8203/#/cluster

8.坑

1.启动容器失败 

原因：启动broker容器，挂载目睹写错了，如下图位置写反了，写成了

/usr/local/rocketmq/broker-master-1/conf

 处理

1.docker ps -a 查看所有创建的容器，包含未启动的

2.docker stop containerID 停止broker容器

3.docker rm -f  containerID 删除容器

4.重新创建容器，执行步骤4

2.访问console失败

未开放安全组

3.控制台没有broker集群信息，如下图，没有

 原因：配置文件中配置的naneserver端口不对
