Start Name Server

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

Start Broker

  > nohup sh bin/mqbroker -n localhost:9876 &
  > tail -f ~/logs/rocketmqlogs/broker.log 
  The broker[%s, 172.30.30.233:10911] boot success...

Send & Receive Messages

Before sending/receiving messages, we need to tell clients the location of name servers. RocketMQ provides multiple ways to achieve this. For simplicity, we use environment variable NAMESRV_ADDR

 > export NAMESRV_ADDR=localhost:9876
 > sh bin/tools.sh org.apache.rocketmq.example.quickstart.Producer
 SendResult [sendStatus=SEND_OK, msgId= ...

 > sh bin/tools.sh org.apache.rocketmq.example.quickstart.Consumer
 ConsumeMessageThread_%d Receive New Messages: [MessageExt...

Shutdown Servers

> sh bin/mqshutdown broker
The mqbroker(36695) is running...
Send shutdown request to mqbroker(36695) OK

> sh bin/mqshutdown namesrv
The mqnamesrv(36664) is running...
Send shutdown request to mqnamesrv(36664) OK


问题1：我yum install java  安装了1.8 默认openJDK，坑啊！
问题2：安装好启动的时候一直起不来，发现打了栈信息，查了很久发现内在最小8G以上，我的机器才2G（最低配置就8G吗）

问题3：测试的时候报 No route info of this topic, TopicTest。
nohup sh bin/mqbroker -n localhost:9876 &  需要改成 nohup sh mqbroker -n localhost:9876 autoCreateTopicEnable=true &
还是不行，查原因是防火墙没关，systemctl status firewalld 查看状态。systemctl stop firewalld.

问题4：RemotingTooMuchRequestException: sendDefaultImpl call timeout 发送失败
namesrver 要改成自己的IP。启动namesrver：
nohup sh bin/mqnamesrv -n "200.200.3.38:9876" &

启动broker ,强制加上本机ip：
echo 'brokerIP1=200.200.3.38' > conf/broker.properties 
nohup sh bin/mqbroker -n localhost:9876 -c conf/broker.properties autoCreateTopicEnable=true &
 
   问题5：安装 rocketmq-console-ng 界面 包的时候，maven  pom.xml 的 rocketmq.version 竟然用得是SNAPSHOT 的包，完全编译不了！！！
　
　最后去了maven 官网去找的版本包编译。
 

感觉一点没有rabbitMq好用，不能再多爱了！！！
