安装rocketmq-mqtt

前期准备：
官方地址：https://github.com/apache/rocketmq-mqtt
RocketMQ从4.9.3 版本开始才支持该功能，所以需要先检查 RocketMQ 的版本是否满足。
RocketMQ 部署参考：https://rocketmq.apache.org/zh/docs/4.x/deployment/01deploy

操作系统和jdk环境：

64-bit operating system, Linux/Unix/macOS recommended
64-bit JDK 1.8+

需要在rocketMQ的配置文件中broker.conf中添加下面的命令以开启mqtt支持

enableLmq = true 
enableMultiDispatch = true 

下面是跟着官网教程走的流程：

git clone https://github.com/apache/rocketmq-mqtt
cd rocketmq-mqtt 
mvn -Prelease-all -DskipTests clean install -U 
cd distribution/target/

maven编译完成之后找到rocketmq-mqtt\distribution\target\rocketmq-mqtt-1.0.2-SNAPSHOT\rocketmq-mqtt-1.0.2-SNAPSHOT\conf\下的service.conf文件编辑里面的配置

sername=test    // Authorization verification account configuration
secretKey=test    // Authorization verification account configuration
NAMESRV_ADDR=xxx  //namesrv access point
eventNotifyRetryTopic=eventNotifyRetryTopic   //notify retry topic, created in advance
clientRetryTopic=clientRetryTopic  //Client message retry topic, created in advance
testTopic=testTopic //Client message retry topic, created in advance
 
metaAddr=192.168.157.129:25000

然后编辑相同目录下面的meta.conf，这个配置文件内容如下

selfAddress=192.168.157.129:25000
membersAddress=192.168.157.129:25000

然后需要提前配置好一级topic如下：

sh mqadmin updateTopic -n 10.22.34
