2. Windows 下安装

  • 解压文件夹

  • 配置环境变量

    变量名：ROCKETMQ_HOME
    变量值：MQ解压路径\MQ文件夹名
    eg、ROCKETMQ_HOME=D:\dev\rocketmq-all-4.3.0-bin-release

  • 修改bin目录下的runbroker.cmd和 runserver.cmd文件
    比如把8g 4g 改成512m， 4g 2g改成256m

    如果启动报错找不到启动类，把红框中的内容复制替换即可。

  • 启动

    Cmd命令框执行进入至‘MQ文件夹\bin’下，然后执行‘start mqnamesrv.cmd’，启动NAMESERVER。

    成功后会弹出提示框，此框勿关闭。

    Cmd命令框执行进入至‘MQ文件夹\bin’下，然后执行‘start mqbroker.cmd -n 127.0.0.1:9876 autoCreateTopicEnable=true’，启动BROKER。成功后会弹出提示框，此框勿关闭。

3. CentOS 下安装

  • 首先将安装包上传至服务器，然后解压压缩包，改个名字

    unzip rocketmq-all-4.9.2-bin-release.zip
mv rocketmq-4.9.2 rocketmq

  • 创建数据存储目录

    mkdir -p /opt/rocketmq/store/broker-a /opt/rocketmq/store/broker-a/consumequeue /opt/rocketmq/store/broker-a/commitlog /opt/rocketmq/store/broker-a/index 
/opt/rocketmq/broker-a/logs

  • 修改配置文件

    cd /opt/rocketmq/conf
vim broker.conf

    增加内容：

    #Broker 对外服务的监听端口
listenPort=10911
#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
#nameServer地址，分号分割
namesrvAddr=localhost:9876
#存储路径
storePathRootDir=/opt/rocketmq/store/broker-a
#commitLog 存储路径
storePathCommitLog=/opt/rocketmq/store/broker-a/commitlog
#消费队列存储路径存储路径
storePathConsumeQueue=/opt/rocketmq/store/broker-a/consumequeue
#消息索引存储路径
storePathIndex=/opt/rocketmq/store/broker-a/index
#checkpoint 文件存储路径
storeCheckpoint=/opt/rocketmq/store/broker-a/checkpoint
#abort 文件存储路径
abortFile=/opt/rocketmq/store/broker-a/abort

    在虚拟机中有可能因为内存不够而启动失败
    修改bin目录下的runbroker.sh 和 runserver.sh 文件
    比如把8g 4g 改成512m， 4g 2g改成256m

    cd /opt/rocketmq/bin

  • 启动

    依次启动nameserver和broker
    这两个命令可以做成alias

    nohup sh mqnamesrv &
nohup sh mqbroker -c /opt/rocketmq/conf/broker.conf &

  • 查看日志

    tail -f ~/logs/rocketmqlogs/namesrv.log
tail -f ~/logs/rocketmqlogs/broker.log

  • 关闭服务

    在bin目录下

    cd /opt/rocketmq/bin

sh mqshutdown namesrv
sh mqshutdown broker

4. RocketMQ web控制台安装

windows和Linux两者都可以安装，都需要下载源码编译使用。

  • 首先下载源代码

    cd /usr/local/soft
wget https://github.com/apache/rocketmq-externals/archive/master.zip

    下载慢可以用复制链接到迅雷里面。或者从百度网盘下载：

    链接：pan.baidu.com/s/1GrkF793X…
    提取码：mh5i

    解压：(百度网盘中的)

    tar -xvf rocketmq-externals-master.tar

    解压出来的文件夹名字：
    rocketmq-externals-master

  • 修改配置文件

    cd /opt/rocketmq-externals-master/rocketmq-console/src/main/resources/
vim application.properties

    修改端口号

    server.port=7298

    修改name server地址（多个地址用英文分号隔开）

    rocketmq.config.namesrvAddr=localhost:9876

    注意后面改了配置文件要重新打包

  • 编译

    cd /opt/rocketmq-externals-master/rocketmq-console/
mvn clean package -Dmaven.test.skip=true

  • 启动jar

    cd target
java -jar rocketmq-console-ng-2.0.0.jar

  • 访问

    浏览器中输入‘127.0.0.1:配置端口’，成功后即可查看。
    eg：http://127.0.0.1:7298
