RocketMq 完整部署

RocketMq 部署

环境

64bit OS, Linux/Unix/Mac is recommended;
64bit JDK 1.8+;
Maven 3.2.x;
Git;
4g+ free disk for Broker server

物理机部署

unzip rocketmq-all-4.4.0-bin-release.zip 
cd rocketmq-all-4.4.0-bin-release/

自定义日志目录

# 在以下文件中替换默认的日志路径 ${user.home}/logs/rocketmqlogs/*
conf/logback_broker.xml
conf/logback_namesrv.xml
conf/logback_tools.xml

自定义参数和数据存放位置

conf 文件夹里有三种配置

  • 2m-noslave 两主,无从的配置
  • 2m-2s-async 两主,两从,同步复制数据的配置
  • 2m-2s-sync 两主,两从,异步复制数据的配置
##以修改 conf/2m-noslave/broker-a.properties 为例

#所属集群名字  
brokerClusterName=DefaultCluster
#broker名字,注意此处不同的配置文件填写的不一样
brokerName=broker-a
#0 表示 Master,>0 表示 Slave
brokerId=0
#nameServer地址,分号分割
namesrvAddr=127.0.0.1:9876

#改成服务器的本机ip,重要!

defaultTopicQueueNums=4
#是否允许 Broker 自动创建Topic,建议线下开启,线上关闭
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=48
#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

#自定义数据存储路径
#存储路径

#消费队列存储路径存储路径
storePathConsumeQueue=/usr/local/rocketmq/store/consumequeue

服务启动

启动name server

  > nohup sh bin/mqnamesrv &
  > tail -f logs/rocketmqlogs/namesrv.log
  The Name Server boot success...

启动broker

 > nohup sh bin/mqbroker -n localhost:9876 -c conf/2m-noslave/broker-a.propertie &
 > tail -f logs/rocketmqlogs/broker.log 
  The broker[%s, 172.30.30.233:10911] boot success...

关停服务

> sh bin/mqshutdown broker
The mqbroker(36695) is running...
Send shutdown request to mqbroker(36695) OK

> sh bin/mqshutdown namesrv
The mqnamesrv(36664) is running...
Send shutdown request to mqnamesrv(36664) OK

尝试发送消息

> export NAMESRV_ADDR=localhost:9876
 > sh bin/tools.sh org.apache.rocketmq.example.quickstart.Producer
 SendResult [sendStatus=SEND_OK, msgId= ...

 > sh bin/tools.sh org.apache.rocketmq.example.quickstart.Consumer

常见报错

发消息报错

org.apache.rocketmq.remoting.exception.RemotingTooMuchRequestException: sendDefaultImpl call timeout

原因:没有配置brokerIP

部署 rockermq console

建议docker 部署
非docker部署参见官方文档 https://github.com/apache/rocketmq-externals/tree/master/rocketmq-console

docker pull styletang/rocketmq-console-ng
docker run --name rocketmq-console -dit -e "JAVA_OPTS=-Drocketmq.namesrv.addr=127.0.0.1:9876 -Dcom.rocketmq.sendMessageWithVIPChannel=false -server -Xms512m -Xmx512m -Xmn256m -XX:PermSize=128m -XX:MaxPermSize=128m" -p 8080:8080 styletang/rocketmq-console-ng bash
# 进入docker查看
docker exec -it rocketmq-console /bin/bash

部署完成,到对应的端口查看即可。可以查看服务监控,历史消息详情,手动创建topic等。

docker 部署

官方镜像 rocketmqinc/rocketmq
部署步骤参见 http://www.justdojava.com/2019/08/26/rocketmq-creator/
