环境

阿里云：centos7服务器

1. 下载源码

wget htt://mirrors.hust.edu.cn/apache/rocketmq/4.3.0/rocketmq-all-4.3.0-source-release.zip

2. 构建

  > unzip rocketmq-all-4.3.0-source-release.zip
  > cd rocketmq-all-4.3.0/
  > mvn -Prelease-all -DskipTests clean install -U
  > cd distribution/target/apache-rocketmq

3. 启动名称服务器

  > nohup sh bin/mqnamesrv &
  > tail -f ~/logs/rocketmqlogs/namesrv.log
  The Name Server boot success...

如果在启动服务器的时候报：
Java HotSpot(TM) 64-Bit Server VM warning: INFO: os::commit_memory(0x00000006c0000000, 2147483648, 0) failed; error='Cannot allocate memory' (errno=12)
那么需要调整rocketMQ的内存

> vim bin/runserver.sh
JAVA_OPT="${JAVA_OPT} -server -Xms128m -Xmx256m -Xmn256m -XX:PermSize=128m -XX:MaxPermSize=320m"

-Xms 的值一定要比 -Xmx  要小不让，也会报错：如下
Initial heap size set to a larger value than the maximum heap size

设置好后启动，

4. 启动broker

 # autoCreateTopicEnable=true 参数可以在启动Broker时指定自动创建Topic:
 > nohup sh bin/mqbroker -n localhost:9876 autoCreateTopicEnable=true &
 > tail -f ~/logs/rocketmqlogs/broker.log 
 The broker[%s, ip:port] boot success...

那么需要调整broker的内存

> vim bin/runbroker.sh
JAVA_OPT="${JAVA_OPT} -server -Xms256m -Xmx256m -Xmn128m"
