   mvn -Prelease-all -DskipTests clean install -U

最终路径

   cd distribution/target/rocketmq-4.9.4/rocketmq-4.9.4

最新版本部署存在问题

Please set the JAVA_HOME variable in your environment, We need java(x64)

解决：本地需要配置 JAVA_HOME 使用命令 vim ~/.bash_profile

JAVA_HOME="/Library/Java/JavaVirtualMachines/jdk1.8.0_171.jdk/Contents/Home"
export JAVA_HOME
CLASS_PATH="$JAVA_HOME/lib"
PATH=".$PATH:$JAVA_HOME/bin"

使用 source /etc/profile 让配置立刻生效

启动nameServer

nohup sh bin/mqnamesrv &

查看日志

tail -f nohup.out  

(结尾：The Name Server boot success. serializeType=JSON 表示启动成功)

启动broker
(-n指定nameserver地址，nameserver服务端口为9876, broker默认端口 10911)

nohup sh bin/mqbroker -n localhost:9876 &

验证是否成功

1. 设置名称服务地址

export NAMESRV_ADDR=localhost:9876

2. 投递消息

sh bin/tools.sh org.apache.rocketmq.example.quickstart.Producer

SendResult [sendStatus=SEND_OK, msgId= ...

3. 消费消息

sh bin/tools.sh org.apache.rocketmq.example.quickstart.Consumer

ConsumeMessageThread_%d Receive New Messages: [MessageExt...

关闭服务器

关闭broker

 sh bin/mqshutdown broker

The mqbroker(36695) is running...
Send shutdown request to mqbroker(36695) OK

关闭 namesrv

 sh bin/mqshutdown namesrv

The mqnamesrv(36664) is running...
Send shutdown request to mqnamesrv(36664) OK

解决

 bin/runserver.sh

修改内存

JAVA_OPT="${JAVA_OPT} -server -Xms256m -Xmx256m -Xmn256m -XX:MetaspaceSize=128m -XX:MaxMetaspaceSize=320m"

Broker内存不足

runbroker.sh

修改内存

JAVA_OPT="${JAVA_OPT} -server -Xms528m -Xmx528m -Xmn256m"
