RocketMQ一直打印RocketmqRemoting closeChannel: close the connection to remote address[] result: true

交代一下背景：

RocketMQ服务端搭建在ECS上面（问题就出在这里）

SpringBoot应用根据官网Demo（参考：https://github.com/apache/rocketmq-spring/tree/master/rocketmq-spring-boot-samples）构建

 

项目启动的时候就开始打印远程地址为空，发送消息失败并且也打印远程地址为空：

RocketmqRemoting: closeChannel: close the connection to remote address[] result: true

 

remote address是空的，开始以为是项目的rocketmq.name-server配置有问题，通过获取RocketMQTemplate的namesrvAddr发现没问题，代码如下

rocketMQTemplate.getProducer().getNamesrvAddr()

 

再看一下SendCallback的Throwable，错误信息如下：

org.apache.rocketmq.client.exception.MQClientException: Send [1] times, still failed, cost [5325]ms, Topic: ADDRESS_PART_TOPIC, BrokersSent: [broker-a]

看到192.168.0.4:10911这个地址就知道问题是出在RocketMQ的Broker服务，192.168.0.4是ECS内网IP地址

这里再看一下Broker启动信息：

 

The broker[broker-a, 192.168.0.4:10911] boot success. serializeType=JSON and name server is X.X.X.X:9876

 

确定问题是brokerIP是服务器的内网IP导致producer无法与之建立连接导致

 

解决方法：

 

//查看broker配置
sh ./bin/mqbroker -m

 

在conf/broker.conf配置文件中增加

 

brokerIP1=X.X.X.X（公网IP）

 

再次启动broker服务

nohup sh bin/mqbroker -n 111.231.XX.XX:9876 -c conf/broker.conf autoCreateTopicEnable=true &

启动结果：

The broker[broker-a, X.X.X.X:10911] boot success. serializeType=JSON and name server is 106.12.x.x:9876

重启本地项目，测试producer发送消息成功
