3. 启动nameserver
[root@iZexci5fo076ghZ bin]# pwd /usr/local/rocketmq/rocketmq-all-4.7.1-bin-release/bin [root@iZexci5fo076ghZ bin]# sh mqnamesrv &
4. 启动broker
[root@iZexci5fo076ghZ rocketmq-all-4.7.1-bin-release]# pwd /usr/local/rocketmq/rocketmq-all-4.7.1-bin-release [root@iZexci5fo076ghZ rocketmq-all-4.7.1-bin-release]# sh bin/mqbroker -n localhost:9876 -c conf/broker.conf autoCreateTopicEnable=true &
5. 启动rocketmq console
java -jar rocketmq-console-ng-2.0.0.jar --server.port=8847 --rocketmq.config.namesrvAddr=localhost:9876 --rocketmq.config.isVIPChannel=false --rocketmq.config.dataPath=/usr/local/rocketmq/store &
6. 阿里云开放8847 端口和9876 端口
7. 访问rocketmq consle 页面
http://127.0.0.1:8847/#/
7. 关闭broker 和 nameserver
