一、RockMQ简介
二、下载RocketMQ
官网下载地址：http://rocketmq.apache.org/dowloading/releases/
选择合适的版本下载即可，小笔这里选的是4.2.0版。值得注意的是，官网提供了源码包和运行包两种，这里看个人需求，选择相应的包，我比较懒，直接选可运行包 rocketmq-all-4.2.0-bin-release.zip
下载完成之后，目录结构大概是这样的。
三、配置环境变量
在启动前，我们要先配置RocketMQ的环境变量。
新增一个系统变量ROCKETMQ_HOME
变量名：ROCKETMQ_HOME
变量值：MQ解压路径\MQ文件夹名
四、启动RocketMQ
启动NAMESERVER
cmd命令框进入到 RocketMQ的安装路径的bin目录下，执行：
start mqnamesrv.cmd
或者直接双击 mqnamesrv.cmd 文件，启动成功会弹出提示框
启动BROKER
cmd命令框进入到 RocketMQ的安装路径的bin目录下，执行：
start mqbroker.cmd -n localhost:9876
启动成功会弹出提示框
假如弹出提示框提示 “错误: 找不到或无法加载主类 xxxxxx”。编辑 runbroker.cmd 文件，然后将 %CLASSPATH% 加上英文双引号。保存并重新执行start语句

五、下载安装RocketMQ控制台
Github下载地址：git clone https://github.com/apache/rocketmq-externals.git
直接下载：https://github.com/apache/rocketmq-externals/archive/master.zip
这里我们只需要用到 rocketmq-console 这个项目
下载完成之后，需要修改 rocketmq-externals\rocketmq-console\src\main\resources 目录下的 application.properties
主要是修改 rocketmq.config.namesrvAddr 的值，即 rocketmq.config.namesrvAddr=localhost:9876
端口也可以自行修改，这里我改成了8070
server.contextPath=
server.port=8070
### SSL setting
#server.ssl.key-store=classpath:rmqcngkeystore.jks
#server.ssl.key-store-password=rocketmq
#server.ssl.keyStoreType=PKCS12
#server.ssl.keyAlias=rmqcngkey
#spring.application.index=true
spring.application.name=rocketmq-console
spring.http.encoding.charset=UTF-8
spring.http.encoding.enabled=true
spring.http.encoding.force=true
logging.config=classpath:logback.xml
#if this value is empty,use env value rocketmq.config.namesrvAddr NAMESRV_ADDR | now, you can set it in ops page.default localhost:9876
rocketmq.config.namesrvAddr=localhost:9876
#if you use rocketmq version < 3.5.8, rocketmq.config.isVIPChannel should be false.default true
rocketmq.config.isVIPChannel=
#rocketmq-console's data path:dashboard/monitor
rocketmq.config.dataPath=/tmp/rocketmq-console/data
#set it false if you don't want use dashboard.default true
rocketmq.config.enableDashBoardCollect=true
#set the message track trace topic if you don't want use the default one
rocketmq.config.msgTrackTopicName=
rocketmq.config.ticketKey=ticket
#Must create userInfo file: ${rocketmq.config.dataPath}/users.properties if the login is required
rocketmq.config.loginRequired=false
修改 rocketmq-console 的pom文件
这个里根据个人情况而定， rocketmq-console 的rocketmq版本默认是4.4.0，把版本换成自己下载的rocketmq版本，前面我们下载的是4.2.0，但是笔者这里遇到一个小坑，就是无论如何4.2.0的依赖就是下载不下来，索性就直接使用4.4.0版，因为版本也是向下兼容，如果下下载的版本号是高于4.4.0的，最好将其替换
4.4.0
如果上一步我们修改rocketmq版本之后，org.apache.rocketmq.console.service.impl.MessageServiceImpl 类的 queryMessageByTopic 这个方法可能会报错，需要修改。
将
DefaultMQPullConsumer consumer = new DefaultMQPullConsumer(MixAll.TOOLS_CONSUMER_GROUP, null);
替换为
RPCHook rpcHook = null;
DefaultMQPullConsumer consumer = new DefaultMQPullConsumer(MixAll.TOOLS_CONSUMER_GROUP, rpcHook);
上述完成之后，开始打包运行
#切换到代码根目录
cd rocketmq-externals
# 切换到控制台目录
cd rocketmq-console
# 构建
mvn clean package -DskipTests
笔者是直接丢到IDEA里去了，所以直接运行项目的，遇到打包出问题的盆友也可以参考
六、启动RocketMQ控制台
最后就是启动 rocketmq-console
通过打包方式的同学，先切换到打包目录，运行
java -jar rocketmq-console-ng-1.0.1.jar
丢IDEA里的同学则直接正常启动项目就行，启动成功之后，浏览器访问：http://localhost:8070
即可看到如下页面
