整合RocketMq提示RemotingTooMuchRequestException: sendDefaultImpl call timeout

在云服务器上安装RocketMq后，项目整合测试

启动好nameServer和Broker之后, 启动生产者会报这样的错误 

Exception in thread "main" org.apache.rocketmq.remoting.exception.RemotingTooMuchRequestException: sendDefaultImpl call timeout

原因： BrokerIP展示的是云服务器的本地IP，不是公网IP;

解决方法：

在conf/broker.conf 中 加入 两行配置

namesrvAddr = 你的公网IP:9876

brokerIP1=你的公网IP

 

重新启动 broker

启动broker的指令要修改下, 要将这个配置文件指定加载

nohup sh mqbroker -n localhost:9876 -c ../conf/broker.conf autoCreateTopicEnable=true &
