docker部署rockermq集群（docker-compose版本）

此处采用docker-compose部署 rockermq主主集群模式

• 创建相关文件夹

此处创建的文件一一对应docker-compose.yml文件中的映射文件夹，酌情创建，主要需要创建配置文件夹。

cd /opt
mkdir rockermq  && cd rockermq
mkdir -p /home/rocketmq/broker-b  && mdkir -p /home/rocketmq/broker-b

• 创建配置文件

注意：此处创建broker配置文件，不配置无法启动。

vim /home/rocketmq/broker-a/broker-a.conf
#配置集群名，同个集群的名字要一样。
brokerClusterName = rocketmq-cluster
#配置节点名，同个集群需保证唯一性
brokerName = broker-a
#0为主节点，>0 为从节点
brokerId = 0
#这个很有讲究 如果是正式环境 这里一定要填写内网地址（安全）
#如果是用于测试或者本地这里建议要填外网地址，因为你的本地代码是无法连接到阿里云内网，只能连接外网。
brokerIP1 = 10.228.83.120
deleteWhen = 04
fileReservedTime = 48
brokerRole = ASYNC_MASTER
flushDiskType = ASYNC_FLUSH
# 内网的(阿里云有内网IP和外网IP)
namesrvAddr=10.228.83.120:9876
autoCreateTopicEnable=true
#Broker 对外服务的监听端口,
listenPort = 10911
#Broker角色
#- ASYNC_MASTER 异步复制Master
#- SYNC_MASTER 同步双写Master
#- SLAVE
brokerRole=ASYNC_MASTER
#刷盘方式
#- ASYNC_FLUSH 异步刷盘
#- SYNC_FLUSH 同步刷盘
flushDiskType=ASYNC_FLUSH
#配置数据化的时候需要用到，此路径为 docker路径。
storePathRootDir=/home/rocketmq/store
storePathCommitLog=/home/rocketmq/store/commitlog
#保存退出，创建broker-b配置文件
vim /home/rocketmq/broker-a/broker-b.conf
brokerClusterName = rocketmq-cluster
brokerName = broker-b
brokerId = 0
brokerIP1 = 10.228.83.120
deleteWhen = 04
fileReservedTime = 48
brokerRole = ASYNC_MASTER
flushDiskType = ASYNC_FLUSH
# 内网的(阿里云有内网IP和外网IP)
namesrvAddr=10.228.83.120:9876
autoCreateTopicEnable=true
#Broker 对外服务的监听端口,
listenPort = 10909
#Broker角色
#- ASYNC_MASTER 异步复制Master
#- SYNC_MASTER 同步双写Master
#- SLAVE
brokerRole=ASYNC_MASTER
#刷盘方式
#- ASYNC_FLUSH 异步刷盘
#- SYNC_FLUSH 同步刷盘
flushDiskType=ASYNC_FLUSH
storePathRootDir=/home/rocketmq/store
storePathCommitLog=/home/rocketmq/store/commitlog
#保存退出

• 编辑yml文件

注意：此步骤为必创建，可大大减少 docker部署服务的工作量，编写完成后一键启动。当然你也可参考此配置文件手动 docker run 一个一个启动。

# 最好在你刚刚创建的配置文件夹下载创建
vim docker-compose.yml
#复制以下配置代码，根据你当前环境酌情修改IP地址，映射路径，容器名等。

启动

#在`docker-compose.yml`配置路径下，当然你也可  `docker-compose -f  配置文件路径 up -d`
docker-compose up -d

最后

• 测试

访问web控制台查看确认一遍是否已有集群。如下图所见：
