Docker部署RocketMQ集群

一、概述

Apache RocketMQ是阿里开源的一款高性能、高吞吐量、队列模型的消息中间件的分布式消息中间件。

关于RocketMQ集群架构的详细介绍，请参考链接：https://blog.csdn.net/Weixiaohuai/article/details/123607472

二、下载镜像

docker pull apache/rocketmq:4.9.4
docker pull apacherocketmq/rocketmq-dashboard

主要用到了2个镜像，第1个用来部署NameServer和Broker，第2个用来管理rocketmq

三、部署

本文主要采用一台服务器来部署RocketMQ集群，集群部署模式采用多master模式，也就是2个NameServer和2个Broker

刷盘机制采用异步复制，异步刷盘

服务器配置：

操作系统：centos 7.6

硬件配置：2核4g

ip地址：192.168.137.138

创建目录

mkdir -p /opt/rocketmq/logs/nameserver-a
mkdir -p /opt/rocketmq/logs/nameserver-b
mkdir -p /opt/rocketmq/logs/broker-a
mkdir -p /opt/rocketmq/logs/broker-b
mkdir -p /opt/rocketmq/store/broker-a
mkdir -p /opt/rocketmq/store/broker-b
mkdir -p /opt/rocketmq/broker-a/
mkdir -p /opt/rocketmq/broker-b/

设置权限

chmod 777 -R /opt/rocketmq/logs/*
chmod 777 -R /opt/rocketmq/store/*

注意：这里如果不设置权限，会导致docker写入文件失败，导致rocketmq启动异常。

创建broker.conf

修改第一个节点配置

vim /opt/rocketmq/broker-a/broker-a.conf

内容如下：

brokerClusterName = rocketmq-cluster
brokerName = broker-a
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 = 192.168.137.138
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=192.168.137.138:9876;192.168.137.138:9877
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

注意：brokerIP1，namesrvAddr，这2个参数，一般配置为内网ip，提供内网访问。如果需要公网访问，这里一定要配置公网ip，否则无法访问。

修改第二个节点配置

vim /opt/rocketmq/broker-b/broker-b.conf

内容如下：

brokerClusterName = rocketmq-cluster
brokerName = broker-b
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 = 192.168.137.138
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=192.168.137.138:9876;192.168.137.138:9877
autoCreateTopicEnable=true
#Broker 对外服务的监听端口,
listenPort = 10912
#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

View Code

注意：brokerName，listenPort这2个参数和第一个节点不一样，其他内容和第一个节点配置一样

编写 docker-compose.yml

vim /opt/rocketmq/docker-compose.yml

内容如下：

最后一步，执行docker-compose

cd /opt/rocketmq
docker-compose up -d

查看进程，使用命令docker-compose ps

# docker-compose ps
    Name                  Command               State                Ports

rmqbroker-b    sh mqbroker -c /home/rocke ...   Up      10909/tcp, 10911/tcp,           
                                                        0.0.0.0:10912->10912/tcp,

rmqconsole     sh -c java $JAVA_OPTS -jar ...   Up      0.0.0.0:8087->8080/tcp          
rmqnamesrv-a   sh mqnamesrv                     Up      10909/tcp, 10911/tcp, 10912/tcp,
                                                        0.0.0.0:9876->9876/tcp

                                                        0.0.0.0:9877->9876/tcp 

确保State状态为up

访问管理平台

http://192.168.137.138:8087

点击右上角切换语言为简体中文，点击集群，效果如下：

看到这个图，说明集群启动正常。

设置持久化配置

上面的 docker-compose.yml，注释掉了一些文件挂载操作，因为新版本的rocketmq无法启动创建文件，直接挂载一个空目录，会启动报错。

复制docker里面的文件

docker cp rmqnamesrv-a:/home/rocketmq/logs /opt/rocketmq/logs/nameserver-a
docker cp rmqnamesrv-b:/home/rocketmq/logs /opt/rocketmq/logs/nameserver-b
docker cp rmqbroker-a:/home/rocketmq/logs /opt/rocketmq/logs/broker-a
docker cp rmqbroker-a:/home/rocketmq/store /opt/rocketmq/store/broker-a
docker cp rmqbroker-b:/home/rocketmq/logs /opt/rocketmq/logs/broker-b
docker cp rmqbroker-b:/home/rocketmq/store /opt/rocketmq/store/broker-b

设置权限，否则会写入文件失败，造成启动失败。

chmod 777 -R /opt/rocketmq/logs/*
chmod 777 -R /opt/rocketmq/store/*

关闭相关docker进程

docker-compose down

修改docker-compose.yml，开启持久化配置
