7、相关问题

1. 内存不足问题

rocketmq Native memory allocation (mmap) failed to map 8589934592 bytes for committing reserved memory.

修改distribution/target/rocketmq-4.7.1/rocketmq-4.7.1/bin目录中的runserver.sh和runbroker.sh。
将JAVA_OPT="${JAVA_OPT} -server -Xms4g -Xmx4g -Xmn2g -XX:MetaspaceSize=128m -XX:MaxMetaspaceSize=320m"改为JAVA_OPT="${JAVA_OPT} -server -Xms256m -Xmx256m -Xmn128m -XX:MetaspaceSize=128m -XX:MaxMetaspaceSize=320m"

2. 防火墙开放端口
   9876 10911

8、安装RocketMQ可视化工具

研发测试时可以安装RocketMQ可视化工具RocketMQ-Console，利于观察。

1. 下载地址：https://github.com/apache/rocketmq-externals
   
2. 修改配置
   
3. 打包mvn clean package -Dmaven.test.skip=true
4. 将jar包传到服务器，使用java -jar启动
