Hi all, I am using rocketmq in ubuntu 16.04. I am following the guidelines from http://rocketmq.apache.org/docs/quick-start/ .
When I try to start the broker I have got the following error. 2018-04-05 09:56:29 WARN ShutdownHook - unregisterBroker Exception, localhost:9876 org.apache.rocketmq.remoting.exception.RemotingConnectException: connect to <localhost:9876> failed at org.apache.rocketmq.remoting.netty.NettyRemotingClient.invokeSync(NettyRemotingClient.java:388) ~[rocketmq-remoting-4.2.0.jar:4.2.0] at org.apache.rocketmq.broker.out.BrokerOuterAPI.unregisterBroker(BrokerOuterAPI.java:221) ~[rocketmq-broker-4.2.0.jar:4.2.0] at org.apache.rocketmq.broker.out.BrokerOuterAPI.unregisterBrokerAll(BrokerOuterAPI.java:198) ~[rocketmq-broker-4.2.0.jar:4.2.0] at org.apache.rocketmq.broker.BrokerController.unregisterBrokerAll(BrokerController.java:641) [rocketmq-broker-4.2.0.jar:4.2.0] at org.apache.rocketmq.broker.BrokerController.shutdown(BrokerController.java:607) [rocketmq-broker-4.2.0.jar:4.2.0] at org.apache.rocketmq.broker.BrokerStartup$1.run(BrokerStartup.java:227) [rocketmq-broker-4.2.0.jar:4.2.0] at java.lang.Thread.run(Thread.java:748) [na:1.8.0_151] 2018-04-05 09:56:29 INFO ShutdownHook - Shutdown hook over, consuming total time(ms): 6471 Could you please help me to solve this problem?
