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，
