使用docker安装RocketMQ

基于 Docker 安装 RocketMQ 在此之前先搞定环境{% post_link docker-install-centos %}或者{% post_link docker-install-ubuntu %} 安装rocketMQ 可参考https://www.jianshu.com/p/706588323276 或者 www.cnblogs.com/qdhxhz/p/11… 为了方便阅读查看笔记，在此一部分直接copy过来，感谢鲁斯菲尔做的视频和笔记，笔者学习的时候也是看了许多他的教学视频，有兴趣的同学可以去哔哩哔哩搜索鲁斯菲尔即可找到。

编写docker-compose.yml

docker-compose的版本不能太老，不然会报错，两个broker两个NameServer一个console 线上不建议使用docker内部IP，问题太多

配置broker.conf

RocketMQ Broker 需要一个配置文件，按照上面的 Compose 配置，我们需要在 当前./brokerconf/ 目录下创建四个配置文件， 因为是双主双从模式部署，所以会有四个broker.conf,这里暂且命名 broker-a.conf 和 broker-b.conf、broker-c.conf，broker-d.conf，内容如下： 注意：主节点：brokerId=0，brokerRole=ASYNC_MASTER，从节点相应做出修改 brokerIP1也需暴露为本机IP

# 所属集群名字
brokerClusterName=rocketmq-cluster

# 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。注册到NameServer的地址，看到这里有两个地址，说明NameServer也是集群部署。
# namesrvAddr=192.168.31.156:9876;192.168.31.156:9877

# 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
brokerIP1=192.168.0.253

# 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
deleteWhen=04

# 文件保留时间，默认48小时
fileReservedTime=120

# commitLog 每个文件的大小默认1G
mapedFileSizeCommitLog=1073741824

# ConsumeQueue 每个文件默认存 30W 条，根据业务情况调整
mapedFileSizeConsumeQueue=300000

# destroyMapedFileIntervalForcibly=120000
# redeleteHangedFileInterval=120000
# 检测物理文件磁盘空间
diskMaxUsedSpaceRatio=88
# 存储路径
# storePathRootDir=/home/ztztdata/rocketmq-all-4.1.0-incubating/store
# commitLog 存储路径
# storePathCommitLog=/home/ztztdata/rocketmq-all-4.1.0-incubating/store/commitlog
# 消费队列存储
# storePathConsumeQueue=/home/ztztdata/rocketmq-all-4.1.0-incubating/store/consumequeue
# 消息索引存储路径
# storePathIndex=/home/ztztdata/rocketmq-all-4.1.0-incubating/store/index
# checkpoint 文件存储路径
# storeCheckpoint=/home/ztztdata/rocketmq-all-4.1.0-incubating/store/checkpoint
# abort 文件存储路径
# abortFile=/home/ztztdata/rocketmq-all-4.1.0-incubating/store/abort
# 限制的消息大小
maxMessageSize=65536

# flushCommitLogLeastPages=4
# flushConsumeQueueLeastPages=2
# flushCommitLogThoroughInterval=10000
# flushConsumeQueueThoroughInterval=60000

# Broker 的角色
# - 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

# 发消息线程池数量
# sendMessageThreadPoolNums=128
# 拉消息线程池数量
# pullMessageThreadPoolNums=128
