recketmq配置dashboard连接问题的解决

在配置虚拟机内的rocketmq连接到win10下的dashboard时报错:

java.lang.RuntimeException: org.apache.rocketmq.remoting.exception.RemotingConnectException: connect to <null> failed

尝试一天修改各种配置无果,翌日重新尝试,仔细阅读日志,发现rocketmq RemotingConnectException: connect to [ip:9876] failed

解决方案

关闭虚拟机centos的防火墙

1.查询防火墙状态

systemctl status firewalld

2.关闭防火墙

systemctl stop firewalld	#关闭防火墙
systemctl disable firewalld    #关闭防火墙开机自启
